Operation Bulletin of Flannel Jacket (Padded)

In my industrial engineering tutorial series, I am sharing an operation bulletin of Flannel Jacket (Padded). You can refer to this operation bulletin to learn about various operations involved, SMV and machine requirements in making Flannel Jacket (Padded). 

A flannel Jacket (Padded) is not an easy style to produce in the sewing line. It has lots of complex processes. Here I describe the operation breakdown of the Flannel Jacket (Padded) with SMV and Machine name. 

Operation Bulletin of Flannel Jacket (Padded) is done by the following table. In this operation bulletin process list, estimated time, machine name, hourly production target quantity at 100% and 60% efficiency are shown. The estimated time (SMV) shown in the below table will vary according to the product method followed and machine and equipment used in actual production. So please be careful while you use the above estimated time against each operation.

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
• SNCS - Double needle Chain stitch
• DNLS - Double needle lock stitch
• DNCS - Double needle Chain stitch
• FOA - Feed of the Arm
• 3T O/L - 3 Thread over lock
• BT - Bartack
• Manual - Helper

To set the line layout 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.

Fabric Types and Needle Size Chart:

Fabric Types	Needle Size
Very fine fabrics (silk, chiffon, organza, voile, lace)	8, 9, 10
Light weight fabrics (cotton, heavier silks, synthetics, spandex, lycra)	11, 12
Medium weight fabrics (velvet, fine corduroy, linen, muslin, tricot, knits, fleece)	14
Heavy weight fabrics (denim, leather, canvas, suiting)	16

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).
