MENDING

Mending is a necessary process where woolens and worsteds fabrics are carefully sought upon generally from naked eyes on an inspection table so that this process can eliminate defects such as holes, tears, broken yarns, and missed warp or weft yarns.

In OCM, the mending capacity of the respective department is up to 12000 meters per day, but if defects are large in number, then the output reduces even up to 5000 meters however these instances are extremely rare as OCM has strict guidelines to keep the quality in check.

Further, the fabric from greasy perch is checked on the mending table and the defects like missing pick, missing end, bunches, and knots are corrected. Float, damage, temple cut, and wrong draft cannot be mended. The usual tools used for mending are-

When the fabric is brought to the mending department it has to be mended and checked for defect and then it has to be sent to the finishing department. Fabric is brought to the department for the weaving department after every shift.

In the mending tables, there are two tube lights overhead the worker and two tube lights underneath the mending table. After mending, perching is done to see whether all the defects in the fabric have been properly checked and mended by the mending department. The perches have two tube lights underneath the glass panel and two tube lights overhead the worker.
