Shuttleless Loom

The main distribution frame (MDF) is an important component between the user and the operator that supplies a telecommunication service and is the only layer in the seven-layer communication architecture that is not fully automated. In this paper, a cross-connect method for simulating the rapier picking of a rapier loom (shuttleless loom) is proposed to imitate the shedding and the picking action to achieve quick switching. Using the designed “shedding device” and “picking device”, a model prototype of the automatic optical distribution frame (AODF) was constructed and tested for verification.

Shuttleless Loom

An article in the National Institute Economic Review in May 1969 described the first results of an inquiry on which the National Institute has been engaged since 1967, in collaboration with research institutes in a number of other countries, into the diffusion of new technology in industry. Ten techniques were originally studied, of which eight were subsequently selected for investigation in greater depth. These included the use of the shuttleless loom in weaving (discussed in a Review article in August last year) and of the tunnel kiln in brickmaking, with which the present article is concerned.

Weaving Loom

Weaving technique represents the development of textile industry. After 25 years of open gate and reform of industry construction, textile manufacturing in China has been developed to a higher level. China had imported many modern weaving machines from Italy, Switzerland, Belgium, Japan, and other countries. The domestic textile machine manufacturers and research institutes developed and manufactured many kinds of shuttleless looms. According to the statistical calculation, the total number of shuttleless looms is more than shuttle looms in use in China currently [1]. The wide use of the shuttleless loom demonstrates a strong technical support to the modernization of textile industry in China. These kind of shuttleless looms are equipped with advanced mechanisms like electronic let-off motion, electronic shedding motion, computer based monitoring, electronic dobby and jacquard machine. They are modern textile machines. Due to the labor denseness of the textile industry and unbalanced development of information technology (IT) in China, the manufacturing organization mode of textile is still old fashioned. Modern machines did not get the most economic and technical benefits. This situation was called “Automation Island”. In this paper, the author will describe his research in the integration of weaving machines through a local net. In the author’s project, which is being supported by the Natural Science Foundation of Zhejiang in China, a research team tries to reform the original computer-based loom controller. The required hardware modification and software programming was added. All looms of the workshop were linked to a central control computer through PROFIBUS to make a local net. Now weaving information of every single loom can be monitored through this central computer. Weaving machine integration is very important textile enterprises. There are a lot of applications using this technology. Web-based (mass customization, MC) customized produce is the future of advanced manufacture. An integrated workshop is a good platform for the enterprisers to expose their business to worldwide market. In this article, the author will discuss effort in this area, including experiments and results.

Shuttleless Loom

The productivity and product quality of a shuttle loom are comparatively less than that of a shuttleless loom because of its high power consumption, more losses of energy, and fault susceptible picking mechanism. The economical commercialization of shuttle loom weaving requires systematic aspects of quality control which enable the mill to adhere to the methods of defect control methods. The current study focuses on the effectiveness of loom patrolling in minimizing fabric defects in the quality inspection department. The t-critical Value distribution of the recorded loom patrol defects and defects recorded in the quality inspection section were calculated to get the rejection region. The study demonstrated how much loom patrol minimizes the number of defects in the inspection department and emphasized loom patrolling as a decisive defect control method for shuttle looms. The t-critical value was calculated from the recorded data of the snap study done through direct observation, interview, and check sheet and these data were also analyzed using the Pareto technique, and focus group discussion. It was found that reed mark, temple mark, over pick and double pick were frequent in the shuttle looms. The causes of the defects were material, process, and human-related problems ranging from spinning section up to finishing section. Scientific Remedies were applied to avoid the successive coming of the faults and minimized the frequency of the defects significantly.
