Progressive Bundle System of Garments Production | Traditional Garment Production System

Posted by Firoz Kabir on Tuesday, June 24, 2014 1

The most common and traditional system of garment production is progressive bundle. Still now it has been used more than other systems.

This system of apparel  production is so called because the bundles of garment parts that are forward sequentially from one process to another. There need to complete a specific operation or component. For example neck join is a single process, through this kind of system an operator will join neck of full bundle then it will forward to another operator.

This kind of system has been called as its name from the bundles of garment parts that are moved sequentially from one to another operation. It is often referred to as the traditional process, has been widely used by the manufacturers for several decades and still in today. The American Apparel Manufacturers Association (AAMA) Technical Advisory Committee (1993) reported that 80 percent of the manufacturers use it. They also predicted that use of this type of system would decrease as firms seek more flexibility.

Bundle sizes may range from two to a hundred parts. Some industries operate with a standard bundle size of particular garments, whereas others vary bundle sizes according to cutting orders, fabric shading, size of the pieces in the bundle, and the operation that is to be completed. Some of them use a dozen or multiples of a dozen of garments because their sales are in dozens. Bundles of garments are assembled in the cutting room where cut parts are matched up with similar parts and bundle tickets.

Bundles of cut parts are transferred to the sewing section to concern operators and they are scheduled to complete the production. One operator is expected to perform the same operation on all the pieces in the bundle, retie the bundle, process coupon, and set it aside until it is picked up and moved to the next operator. In this process may require a high volume of work in process cause of the number of units in the bundles and the large buffer of backup that is needed to ensure a continuous work flow for all operators.

It might be used with a skill center or line layout depending on the order that bundles are advanced through production. Each style may have different processing requirements and thus different routing. Routing identifies the basic operations, sequences of  production, and the skill centers where those  operations are to be performed. Many of the operations are common to multiple styles in that case work may build up waiting to be processed.

Advantages of  progressive bundle system:
The of this system is of making may depend on how the production system is set up and used in a plant. It may allow better utilization of specialized machines, as output from one special purpose automated machine may be able to supply several operators for the next operation. Small bundles of fabrics allow faster throughout unless there are bottlenecks and extensive waiting between operations.

Disadvantages of progressive bundle system:
This processing type is driven by cost efficiency for individual operations. The operators perform the same operation on a continuing basis, which allows them to increase their speed and productivity but who are compensated by piece rates become extremely efficient at one piece operation and may not be willing to learn a new style because it reduces their efficiency and earnings. Individuals that work here  are dependent on other operators and the final product.

Slow processing, absenteeism, and equipment failure may also cause major bottlenecks within the system. Large quantities of work in process are often characteristic this may lead to longer throughput time, poor quality concealed by bundles of fabrics, large inventory, extra handling, and difficulty in controlling inventory of whole processing.
