Full form of Machine Name:

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

• SNLS - Single needle lock stitch
• DNLS - Double needle lock stitch
• DNCS - Double needle chain stitch
• DLM - Single needle lock stitch Edge Cutter
• FOA - Feed of the Arm
• MNCS - Multi needle chain stitch
• 3T O/L - 3 thread over lock

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.

Operation Breakdown 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). 

Nice. I have create some reels which can help sewing lovers.  Please follow and watch Flap sewing by pattern sewer machine, Shirt Plucket cutting video, Flannel Shirt Bottom hem video. Thanks
