Operation Bulletin of Short Sleeve Polo Shirt

Today We will learn to prepare the Operation Bulletin of Short Sleeve Polo Shirt in my industrial engineering tutorial series. You can refer to this operation breakdown or bulletin to learn about various operations involved, SMV and machine requirements in making Short Sleeve Polo Shirt. 

A Short Sleeve Polo Shirt is an easy style to produce in the sewing line. It has only very few complex processes. Top center placket and Side Vent  attach. Here I describe the operation breakdown of the Short Sleeve Polo Shirt with SMV and Machine names. 

Operation Bulletin of Short Sleeve Polo Shirt is done by the following table. In this operation bulletin process list, estimated time, machine name, hourly production target quantity at 100% and 75% 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

3T O/L - Three Thread Over Lock

4T O/L - Four Thread Over lock

DLM - Single Needle Edge Side Cutter

2T F/L - Three Thread Flat Lock

BH - Button Hole

B/T - Bartack

Manual - Helper

How to set the target per hour in the Sewing line of the Garment Factory?

It will be best to set the line layout target based on line efficiency, line cost and delivery date of the 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 needle or Sharp Point" Needle to stitch this item.

Single Needle Lock Stitch   --- DB 1
Single Needle Edge Side Cutter     --- DB 1
Three to Five Thread Overlock      --- DC 21
Two Thread Flat lock                     --- UY 128

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).
