Design and Development of a Novel Mechanism for the Removal of False Selvedge and Minimization of its Associated Yarn Wastage in Shuttleless Looms

Sajid Ahmed Qureshi, M. Ramesh Kumar and C. Prakash

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.
