Full form of Machine Name:

In the above table a short name of sewing machines is written. Followings are the abbreviation of those short machine codes. 

SNLS - Single needle lock stitch

DNCS - Single needle chain stitch

4T O/L - 4 Thread Overlock

Set the line target:

It will be best to set the line layout target based on line efficiency, line cost and delivery date of style.

Formula to set the 100% target:
Daily Target = (Worker x Working hour x 60/ SMV) x efficiency %
Basic Pitch Time (BPT) =Total SMV / Total Manpower

We can use “Ball Point or Sharp Point" needle to stitch this item.

Very fine fabrics (silk, chiffon, organza, voile, lace)	8, 9, 10
Light weight fabrics (cotton, heavier silks, synthetics, spandex, lycra)	11, 12

Operation Bulletin makes our work easy to set up a production line in the apparel industry. We can easily manage machine and operator requirements for any sewing line by this. But it is necessary to do an operation breakdown to prepare a machine layout and line balancing by industrial engineering (IE).
