Abstract
This report is concerned with the Troubleshooting in weaving mill. I havelimited it to the problems of sizing department, mechanical, electrical, filling andother faults those occurred in loom.To me troubleshooting means thinking about the many factors which togetheror individually create the problems in running of machine or quality of fabric. Timespent thinking before starting the new design of fabric is better than wasting the timeand production of after occurring the problem. Infect thinking and thus solving theproblem should take place all the time.The first chapter is about the introduction of organization in which I havewritten the brief introduction of the founder and chairman of the group, the groupperformance. This chapter is also consisting of all the mills' history, like Nishat millslimited Faisalabad having seven spinning units containing 176500spindles.
