Stitching department

The line supervisor analyzes the garment construction of the style to be loaded to the line. He calculates the machine requirement for the style, based on the garment construction.

Line supervisors calculate the estimated cost per operation. In the piece-rate-production system, the supervisor sets piece rates for stitching operations. Those factories that have industrial engineering departments calculate direct labour costs based on the standard allowed minutes (SAM) to produce a garment.

The floor in-charge and line supervisors plan the daily production output. They take information on upcoming orders from merchandisers or the planning department and plan manpower and machine requirements in advance.

Line supervisors set the sewing line for new orders. Line setting involves the tasks of placing sewing in a sequence, by allocating operators to each machine, giving work to operators and helpers and giving instructions to operators on how to undertake operations and the required stitching quality.

The sewing department stitches garments and makes clothes. Operators sew garments using different types of sewing machines. An operator can be given single or multiple operations to sew.

To get maximum production from the line, line supervisors balance line by adding additional operator, or by clubbing operations. Read this article to learn about line balancing.

Marking is done on the garment component needed to point a position from where the stitching is to be done. Helpers mark on garment parts as per process requirement by using marking chalk and magic marker.

Garment components might need to be folded and ironed prior to stitching to improve seam quality. Portable irons are used for ironing on garment parts.

Garments are checked in line and off the line. The purpose of checking garments is to reduce defect generation from the line. The end-of-line checker segregates defective pieces from the good pieces. Read quality checking procedures in garment production.

After segregation, defective garments are sent back to the stitching section. Seams are repaired by re-stitching. If defects are related to the fabric, part changing is done by replacing the defective component with the correct part.

The department maintains various logbooks and records. The sewing department records the details of receiving cuttings from the cutting department and issuing garments to the finishing department. They make reports of the daily production on a line-wise basis and the manpower used in each line.

In most factories, line supervisors are responsible for bringing sewing operators and recruiting operators through skill assessment tests.
