What is Spreading | Methods of Spreading In Cutting Section

Cutting, Spreading

Spreading is a pre-cutting process. The main objectives of the spreading process is to lay the several fabric plies essential for the production process to the marker length without any tension on the fabric. The lay height depends on order size, cutting ratio, fabric characteristic, capacity of the spreader, cutting method and equipment used. The preference of mode of spreading will influence the cost of spreading as well as finished garment quality. The composition of each spread, i.e. the number of plies of each colour is obtained from the cut order plan.

Spreading Methods

1. Machine Assisted Spreading 
2. Semi- Automatic Fully Automatic 
3. Manual Spreading 

Manual Spreading Machines: Fabric is carefully pulled out by hands, then spread & cut with requirements. 
Advantages:

• Easy to operate 
• Low investment
• Suitable for small scale garment industries

Limitations:

• Speed limitation 
• Skilled labor required to operate 
• Chances of improper selvedge alignment
• Small roll size

Semi-Automatic Spreading: It is same as Manual Spreader  Movement along the table and fabric pulling can be controlled by buttons
Advantages:

• Fast and economical 
• Proper selvedge alignment
• Ease to operate with electronic clutch

Limitations:

• Fabric roll loading, cutting is still manual
• Not suitable for large scale manufacturing houses
• Small roll size

Fully Automatic Spreading Machines

• Automatic loading/unloading device for fabric rolls 
• Automatic roll turning arrangement for face to back lay 
• Automatic leveling device for fabric edge alignment.
• Automatic cutting device at the end of a run 
• Automatic tensioning device to control fabric tension 
• Automatic lay height sensing elevator 
• Programmable lay length, ply height and step-laying
• Spreading seeds up to 140 m/min
