Bundling in Garment Manufacturing: Process, Types & Flow

Sorting and Bundling of Cut Components

The sorting and bundling of cut components is the final cutting-room operation carried out in the cutting room. During this stage, a full set of components for each cut style is formed, and the cut articles are grouped by size and, when several coloured fabrics are laid for one order, by colour or shade lot. This ensures that the correct components move together through the sewing line in a controlled manner.

What Is Bundling in Garment Manufacturing?

Bundling in garment manufacturing is the process of arranging garment components from the cut stacks after layer cutting and making bundles with a selected number of garment pieces. Normally, a rope or a fabric strip, often made from cutting waste, is used to tie the parts together, although factories may also place bundles in trays, baskets, polybags, or trolleys without physically tying them.

In bulk cutting, many fabric layers are cut together, and multiple garments of the same or different sizes and colours may be cut from a single lay. Without sorting and bundling garment parts of the same size, colour, and fabric layer, the cuttings cannot be sent directly to the stitching operator. Proper bundling therefore helps the cutting department count pieces, control cut-work inventory, and issue cut parts to the sewing section according to production requirements.

Formation of a Full Set of Components

The full set of component bundles for a style is placed on a table. They are tied with fabric strips, usually cut from the edges of fabrics used in the cutting process, to hold the components together and prevent their loss during transportation to the sewing line. The bundles of components that will later be joined are often combined into larger bundles. For example, one large bundle may contain the outer sleeve, under sleeve, and cuff bundles. If the sewing line has a separate section for processing small components, those bundles are sorted separately and transported directly to that section.

Grouping of Cut Articles by Size

A full set of component bundles for each size is completed separately. This ensures the consistent processing of one size of a style in the sewing line, the attachment of correct size labels, and the separate packing and recording of completed goods according to size.

Grouping of Cut Articles by Colour

The grouping of cut articles by colour is necessary when different coloured garments are processed in the same order. It allows the use of corresponding sewing threads and matching accessories such as buttons and zippers. It is also usual practice to pack and record ready goods according to colour.

Identification of Bundles

Top-ply labeling system

Most sewing rooms use the bundling system, in which small batches of garments move from one workstation to another in a controlled manner. To prepare the cut work properly, operators must be able to identify each pile. When a marker is used, the style number, size, and part identification may already be part of the plot. If markers are not used, a top-ply labeling system is required.

After cutting the fabric lay and attaching a sticker or bundle ticket, all garment components in stack form are sorted according to size and colour. To avoid mistakes in sorting, it is better to use a code number or similar identifier on each pattern piece. In practice, components of the same size, colour, and ply number must be kept together.

The Bundling Process and Bundle Size

Bundling is usually a manual process carried out after sorting the components and ply numbering. Depending on the production system, a factory defines its bundle size, that is, the number of units tied or grouped together. A bundle may contain 2, 5, 10, 20, or any other suitable number of garment units, and it may include all the components required for that number of complete garments.

Example

For example, in a T-shirt factory, the main parts are the front panel, back panel, two sleeves, and neck binding. If the cutting room makes a bundle for 20 T-shirts, that bundle will contain 20 front panels, 20 back panels, 20 neck bindings, and 40 sleeves.

Bundling Systems in Apparel Manufacturing

Manufacturers use a variety of bundling methods depending on their production needs. The following systems are among the most common in apparel manufacturing:

a) Item bundling

Item bundling – all pieces that comprise one garment are bundled together.

b) Group bundling

Group bundling – several garments, often 10–20 units, are put together in one bundle and given to a single operator or team to sew.

c) Progressive bundling

Progressive bundling – pieces corresponding to specific sections of the garment, such as sleeves or a collar, are bundled together and given to one operator. Other operators sew other parts of the garment, which are then assembled into the finished garment in the final phase.

d) Unit production system (UPS)

Unit production system (UPS) – individual garment pieces are delivered to operators through a computerized, fully mechanized transport system that runs throughout the manufacturing facility. Using a UPS monitoring system, a manufacturer can track garment production, identify sewing slowdowns, and reroute garment pieces when necessary. This reduces manual handling of bundles, lowers labour costs, and supports short-cycle manufacturing.

e) Modular or team-based manufacturing

Modular or team-based manufacturing – another type of bundling and work organization that combines some of the above characteristics. Often associated with cellular manufacturing, it groups sewing operators into small teams, commonly eight to ten people. Rather than each operator performing a single task, the team works together on a garment from start to finish.

Quality Control and Transfer to Sewing

Bundling workers also carry out important quality-control functions. They inspect the garment pieces for cutting problems, fabric irregularities, missing parts, or any other problems that may have occurred in production up to that stage. When sorting and bundling are complete, all garment components are sent to the sewing section in the required sequence.

Conclusion

Bundling in garment manufacturing is a critical cutting-room activity that keeps components organized, identifiable, and ready for efficient sewing. By grouping cut parts by size, colour, and bundle quantity, factories improve production control, reduce errors, and maintain quality throughout the workflow. Effective cutting room bundling therefore plays an essential role in smooth and accurate garment manufacturing.
