A novel mechanism for the elimination of false selvedge in rapier looms was successfully designed and developed, which functions to grip the protruding weft ends after each pick insertion during the weaving process, with subsequent cutting and suction of the protruding ends. The task is otherwise, presently performed by the formation of dummy or false selvedges in the fabric, requiring additional yarn other than that required for the actual fabric. A significant amount of yarn is wasted to form false selvedges, as they are removed and disposed as hard waste post weaving, which consequently increases the cost of fabric and narrows the profit margins. The developed mechanism was successfully installed and commissioned on an indigenous rapier loom leading to a reduction in the amount of hard waste otherwise generated, without affecting the normal functioning of the loom and the weaving process. The amount of reduction in hard waste was estimated and the quality of fabric manufactured before and after the installation was tested and analyzed. [ABSTRACT FROM AUTHOR]

At present, the rapier loom has gradually become the mainstream equipment in the manufacturing industry. In order to make the rapier loom realize automated production and further improve the production efficiency of the rapier loom, improve the programmability of the system, and reduce the cost of system maintenance. The thesis developed a rapier loom control system based on embedded soft PLC, and carried out experiments and applications in the field. The contribution and innovation of this paper is to develop a complete low-cost control system, and through a genetic algorithm optimized PID algorithm to complete the more effective control of the loom tension system. The embedded soft PLC system proposed in this paper reduces the overall maintenance cost of the system and improves the programmability of the system. This text carries on the systematic scheme design to the embedded soft PLC from the hardware system and the software system respectively. First, according to the actual requirements, this article designs the overall scheme of the embedded software PLC hardware system with STM32F407ZGT6 as the core. Then this article is based on the embedded soft PLC hardware platform, according to the international standard of industrial control programming, writes the embedded soft PLC low-level driver software. Secondly, this article analyzes the factors that affect the warp tension during the operation of the rapier loom, and proposes the use of genetic algorithm to optimize the warp tension control method of the traditional PID algorithm. Finally, we conducted verification tests and on-site application debugging for the entire set of rapier loom embedded soft PLC control system. We controlled the warp tension as the main experimental object. The results show that this control system effectively improves the control accuracy of the warp tension of the rapier loom and meets the actual needs of industrial applications. The whole system has a good application prospect in the warp tension control of rapier looms. [ABSTRACT FROM AUTHOR]

Adopting the format of an edited and annotated conversation, Danish researcher and designer Rosa Tolnov Clausen, American artist and professor Marianne Fairbanks and British writer and professor Jessica Hemmings discuss some of the circumstances in which community hand weaving projects may flourish. Decisions around the types of space Clausen's Weaving Kiosk (2017–ongoing) and Fairbanks's Weaving Lab (2016–ongoing) have occupied, how hand weaving may be made portable, the impact of duration and responsibility toward the material, as well as social, outcomes are discussed. While our conversation tries to understand what is shared by the Kiosk and Lab, we also acknowledge where different cultural and historical contexts cause the potential and challenges of these two initiatives to differ. The Weaving Kiosk and Weaving Lab are not intended as performances, but instead place emphasis on how hand weaving may build social connections. The format of this article foregrounds the conversational nature of social hand weaving and hopefully offers inspiration to others interested in expanding the purpose of contemporary hand weaving and textile scholarship.

An electropneumatic shedding mechanism has been designed and developed for making a prototype sampling loom with having computer-controlled shedding in our project supported by Turkish Government. In the study, in order to choose the best suited healds and heald frame movement distance for shedding system, different shedding geometries were studied and compared in relation to the cloth fell distances and warp elongation in fully open-shed positions. Mechanical and electrical designs were based on the most effective shed geometry. This article includes the developed shedding mechanism, comparison of the shed geometries drawn by using SolidworksVR as well as the strength analysis of pneumatic pistons. [ABSTRACT FROM AUTHOR]

As a definition of craft practice, the workmanship of risk emphasises the judgement and skill of the crafter, as they engage with materials, tools, and techniques to produce artefacts. Through experimental design research methods, self-forming three-dimensional textiles were created with the aim to develop both the use of digital and automated tools for weaving, and language to describe the process of textural forming in weaving when hand and machine meet. Examples of experimental work illustrate the potential of industrial looms as tools for crafting complex textile systems and expressions. The results include a method for crafting at the intersection of the workmanship of risk and CAD/CAM, providing a framework for this hybrid practice, while a new language of textile forming for craft including industrial and CAD/CAM tools emerges.

Development of figured warp colored products on dobby loom was discussed. Based on dobby weaving condition, technology key points of yarn configuration, composition design, weave design and looming drafting of figured warp colored fabric were studied. On 16 heddle electronic dobby rapier loom, 4 new figured warp colored products with different characteristics were developed. It was pointed out that figured warp could be designed to be uniformly distributed across entire width and strip distribution according to composition requirements. Ground weave could be single-layer structure or double-layer structure. Visual effect of fabric was determined by color contrast and color matching of figured warp and ground warp. It is considered that the developed fabric can be used for high-end men s & women s suits and casual fabric. [ABSTRACT FROM AUTHOR]

The aim of this paper is to shed light on the research and travels of the pioneering Danish textile researcher Margrethe Hald regarding the rare and ancient warping technique known as the tubular loom. It retraces Hald’s steps on her quest for the tubular loom from the study of Danish bog finds through Egyptian textile remains to surviving weaving traditions in Syria and South America. Hald’s method of combining archaeology, ethnology, textile craft, and art history in her research created new understandings of past and present textile traditions and paved the way for modern interdisciplinary research. By revisiting Hald’s published and unpublished work on the subject, as well as letters and notes, this paper demonstrates how archival studies can improve understanding of the work carried out by early textile researchers.

In order to reduce the energy consumption of air jet looms, a new weft insertion method of main nozzle + weft insertion sheet was proposed. Firstly, based on SolidWorks software, a new type of weft insertion structure model with air passage was established, the SpaceClaim module of the finite element analysis software Ansys was used to extract the flow field in the new weft insertion sheet. Finally, the numerical simulation method was used to obtain the velocity cloud diagram of the symmetrical section of the new weft insertion sheet, the velocity attenuation curve on the center line of the airflow weft insertion, the air consumption and the velocity section diagram. The results show that when the air supply pressure is 0.3 MPa, the air consumption of the new weft insertion sheet in the full flow field is 1.997 m3/h, and the air consumption in the full flow field of the conventional single-hole auxiliary nozzle is 2.822 m³/h. The weft insertion method of nozzle + weft insertion piece is feasible and can effectively reduce air consumption. [ABSTRACT FROM AUTHOR]

This paper discusses some of the insights that have been gained from the study of the textile tools from the Etruscan settlement of Poggio Civitate di Murlo and coeval textiles recovered from the adjacent cemetery site of Poggio Aguzzo di Murlo. Over 1,600 textile tools (including spindle whorls, loom weights, and spools) are analysed from a functional perspective, and results suggest that the textiles found in burials were likely produced at the site. This new information is discussed in light of other subsistence and craft activities documented at the settlement, all of which indicate an inward-oriented economy that catered to the local elites and the populations they controlled.

In this paper, the design of the remote monitoring system for the industrial interconnection of the intelligent high-speed loom is carried out from the hardware system and the software system. The overall design scheme of the system is as follows. The transmission control protocol/internet protocol communication protocol based on the socket programming interface is used for data transmission between the local executor and the cloud server. The browser/server architecture is selected for data communication between the web server and remote client. The data interaction between the web server and the remote client is realized by Ajax (Asynchronous JavaScript and XML). Finally, the remote monitoring function of the industrial interconnection of the intelligent high-speed loom is realized. The effective communication distance of the hardware circuit control board of the intelligent high-speed loom monitoring system is 150 m, which meets the needs of the industrial field. The client-side of the system can be compatible with different browsers and can monitor the running state of high-speed loom in real-time. Once the loom breaks down, the system can judge the cause of the failure through algorithm analysis, and the visual interface can achieve a better human–computer interaction effect, which can meet the needs of the industry for the intelligent remote monitoring system of the high-speed loom. The effective communication distance of the hardware circuit control board of the intelligent high-speed loom monitoring system is 150 m, which meets the needs of the industrial field.

The textile industry has a long history and a large market scale around the world. High-speed loom belongs to the high-end production equipment of the textile industry with the characteristics of high precision, high speed and high efficiency. However, due to its expensive cost and complex structure, there might be significant loss once a high-speed loom breaks down. At present, the monitoring and troubleshooting of high-speed loom operation mainly depend on the experience of maintenance people to carry out inspections, which is inefficient, time-consuming, laborious and less efficient. In this paper, a fault diagnosis method for high-speed loom based on rough set and Bayesian network is investigated. Rough set theory is applied to reduce the attributes of fault causes and results and find the minimum reduction and classification rules. Then, a Bayesian fault diagnosis network model is built, and the probability of each fault cause is calculated to find the maximum probability. Finally, the diagnosis results are obtained. The experimental results have demonstrated the reliability and convenience of the faults diagnosis method for the high-speed loom. [ABSTRACT FROM AUTHOR]

A new duplicate of the hymn dubbed ‹Ishtar-Louvre› is published here. It supplies part of the lost end of the text, and prompts new interpretations of some previously known passages (uzunšu liškun mummāšipu i 2 and 4; in the play of the loom, Ishtar determines the sex of the baby i 45 sq.) as well as lexical remarks on tūqaru/tūgaru, sissiru.

This paper examines Late Bronze Age spindle whorls and loom weights found in the ongoing excavations at Beycesultan Höyük restarted in 2007 in context. Some supporting evidence on the functions of weaving tools has been obtained based on the context. The lack of written sources on weaving in Western Anatolia entails directly description of the weaving of this region through archaeological material. Spindle whorls in various forms and sizes indicate that different types of yarns were produced in the settlement while the numerous loom weights in the settlement imply the weavings be woven on the warp-weighted vertical looms of different sizes. The weaving tools found in the houses with several rooms indicate that weaving was practiced as a specialized occupation by some members of the household. It may be assumed that spinning could be done in almost any room, but wider courtyards were generally preferred for weaving with a loom. The storage rooms or living rooms of the houses were areas where the weaving tools were collected/stored after the weaving was stowed/stored. Despite similarities with Central Anatolia and Western Anatolia, local effects on weaving tools are quite dominant. With a large number of decoration elements unique to Beycesultan, some spindle whorls and loom weights found also support this view. The data renders Beycesultan höyük as an important textile production center in Western Anatolia. Hundreds of spindle whorls and loom weights found that will also dim light on the settlement and the region's Late Bronze Age weaving in region. [ABSTRACT FROM AUTHOR]

This paper brings Barad's agential realism into relation with educational ethnographic work, and longstanding concerns with matters of inequality. We extend previous work that foregrounds time and space in particular places, and that resists approaches to inequality that generalise about 'best practices' for schools in communities facing challenging circumstances. An Axminster Jacquard carpet loom—located in a particular place, the City of Geelong—becomes a specific point of entry to a discussion of agential realism, ethnography and inequality. This carpet loom was once a key machine in a thriving Geelong carpet factory employing families intergenerationally; it is now a demonstration machine in the Geelong National Wool Museum, operated by skilled carpet weavers (now employed as demonstrators) formerly employed at the (now closed) factory. We read questions of deindustrialisation and schooling through the carpet loom as apparatus, working with the questions that it materialises about educational research, ethnography and inequalities.

In air-jet weaving looms, the main nozzle pulls the yarn from the prewinder by means of a high velocity air flow. The flexible yarn is excited by the flow and exhibits high amplitude oscillations. The motion of the yarn is important for the reliability and the attainable speed of the insertion. Fluid-structure interaction simulations calculate the interaction between the air flow and the yarn motion and could provide additional insight into yarn behavior. However, the use of an arbitrary Lagrangian–Eulerian approach for the deforming fluid domain around a flexible yarn typically results in severe mesh degradation, vastly reducing the accuracy of the calculations or limiting the physical time that can be simulated. In this research, the feasibility of using a Chimera technique to simulate the motion of a yarn interacting with the air flow from a main nozzle was investigated. This methodology combines a fixed background grid with a moving component grid deforming along with the yarn. The component grid is, however, not constrained by the boundaries of the flow domain allowing for large deformations with limited mesh degradation. Two separate cases were investigated. In the first case, the yarn was considered to be clamped at the main nozzle inlet. For the second case, the yarn was allowed to move axially as the main nozzle pulled it from a drum storage system.

Hippolytus (Asiatic tradition, 3rd century) likes to approach the reality by creating resemblances between all kind of objects, events and living beings. Despite metaphorical language is less accurate than scientific reasoning, it might, however, reflect better the dynamism of the reality. For instance, the history of salvation is compared to a loom (cf. De Antichristo 4), due to its strong biblical roots and omnipresent in Roman life; therefore, this would not only generate greater interest in the audience but also it could arouse among some of them connotations linked to the Myth of Penelope, the myth of social content in Plato's Politikos, etc. By this passage, Hippolytus provides the following correspondence between different aspects of a textile work-shop and some details of the history of salvation: the warp, strong and durable as the Spirit; the weft, thicker and weak, such as the flesh of Christ, the patient workers, the Patriarchs and the Prophets; the golden threads of the edge meaning the grace of God; the loom's shuttle weaving the artistic design, the same as the Logos and finally, the mast of the loom meaning the Cross of Christ.

Loom weights are difficult to date as they are fairly consistent in weight and shape over long periods. This article discusses the dating of 194 light loom weights with no contextual data from Szâzhalombatta, Hungary. The aim of this paper is to present previously unpublished material and identify the period to which the textile tools belong. It shows that the light loom weights in this study most likely belong to the Hallstatt period based on the find site's characteristics and comparison with loom weights from dated contexts.
