Operation Bulletin of Stretch Jogger

Today We will learn to prepare the Operation Bulletin of Stretch Jogger 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 Stretch Jogger. 

A Stretch Jogger is an easy style to produce in the sewing line. It has only very few complex processes. Below Knee reflective heat seal tape, Side zipper pocket, inseam Top Stitch. Here I describe the operation bulletin of the Stretch Jogger with SMV and Machine names. 

Operation Bulletin of Stretch Jogger is done by the following table. In this operation bulletin process list, estimated time, machine name, hourly production target quantity at 100% and 65% 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.

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.

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). 

Visit here to know what is operation breakdown. You can visit my website to learn more about the bulletin or breakdown of garments.
