Industrial training is an important part of the theoretical studies. It is of an immense importance in the field of technology. It offers the student to explore the valuable treasure of experience and an exposure to real work culture followed by the industries and thereby helping the students to bridge gap between the theories explained in the books and their practical implementations.

Training project plays an important role in future building of an individual so that students can better understand the real world in which he has to work in future. The theory greatly enhances our knowledge and provides opportunities to blend theoretical with the practical knowledge.

ACKNOWLEDGEMENT

It is almost inevitable to incur indebtedness to all those who generously helped me by sharing their invaluable time and rich experience with me, without which this project would have never been accomplished. There is always a sense of gratitude which one express to other for the helpful and ready service they render during all work at life. I gratefully acknowledge the inspiration, encouragement, guidance, help and valuable suggestions receipt from the following well wishers.

In the beginning, I deeply convey my sincere thanks to Ms. MANISHA(HOD of ECE department) for their regular assistance all through the project for their precious contribution on the training study . She has been benevolent enough to lend me help and spare his valuable time throughout the training. She has been immensely contributive with his ideas, constructive criticism and motivation which were the guiding line during the entire tenure of studies.

Finally, it is grace of almighty GOD, my parents and esteemed friends, who has been a source of strength and confidence for me in this endeavor

ABSTRACT

Spinning is the process of conversion of fibre into yarn. The spinning process includes variousoperations such as cotton mixing, carding, combing, drawing, winding. Winding is the final process inspinning mill where the yarn of small quantity is wound into a big package known as cones. The importantaspect in winding is removal of defects or faults in yarn produced. In manual winding when there isdiscontinuity of thread, during removal of faults, the knot is made by a human. This reduces the quality ofyarn. To overcome this disadvantage, autoconer is used. Autoconer is an advanced machine used in windingprocess to get a high quality yarn with low man power. Here, threads are spliced automatically. Splicing meansthe process of opening of broken ends and retwisting the ends after the removal of faults. Here the joined yarnlooks like parent yarn. Thus, the quality of yarn is enhanced. The drawback of autoconer is, waste collected bysuction motor gets deposited on the suction panel and it should be disposed manually for a periodic timeinterval. If the waste is not removed it reduces the operating efficiency of the suction motor. This leads to reduction in quality of yarn. The aim of the proposed work is to design an automatic waste removal system using PLC (Programmable Logic Controller) which helps us to further increase the efficiency of the suction

motor and thus the quality of yarn.

INTRODUCTION

Spinning is the part of the textile manufacturing process. It is the process of twisting together of drawn out strands of fibres to form yarn, though it is colloquially used to describe the process of drawing out, inserting the twist, and winding onto bobbins. Quality is an important factor to be considered in all industries. Quality of textile is based on type of yarn used. So that, all manufactures of yarn concentrate more in quality so that they can withstand in the market. To be able to make agreements, accurate values which characterize quality are required. Quality of the products are provided by the testing instruments for example, for assessing the quality of fibres, slivers, rovings and yarns .Without the availability of such reliable values, it would be extremely difficult or even impossible to form the basis for a dialogue with the modern textile world. Therefore, great importance is attached to the accuracy and reproducibility of the quality determining values. Table 1 shows the

results of inter-laboratory tests for analysing the quality of yarn.
