Various Fusing Equipment
The equipment used for fusing can be divided into:
Specialized fusing presses:
A number of different types of fusing press have been developed over the years, providing control of the heat and pressure applied to the garment part and providing for fusing to takes place on flat sections of garments that have not yet been sewn. In many companies, such fusing presses are sited in the cutting room and the fusing operation takes place before transferring the garments to the sewing room. Fusing presses vary in the way they operate and these differences affect both the quality of the fusing and productivity of the operation.

A diagram below shows the principle of operation of this type of fusing press. It consists of two horizontal metal plates between which the fabric and interlining laminate are sandwiched. In the simplest mode of operation, the operator places the garment part face down on the lower platen places, the interlining resin side down on the top of it in the correct position, and closes the press.
Continuous fusing systems
These systems operate by passing the garment part, with its interlining placed on it, past a heat source and, either simultaneously or subsequently, applying pressure. Heat is provided in one of three ways:
- With direct heating, the conveyor belt carries the components to be fused into direct contact with a heated surface, either a drum or curved plates.
- With indirect heating, the components are carried through a heated chamber.
- With low temperature, gradient heating, the components are carried through a pre-heating zone. Heating is either direct or indirect. With this approach, the temperature reached the glue line is only just above that required to make the resin a viscous fluid and in some cases, fusing takes place satisfactorily with a glue line temperature of the only 120oc.This reduces the possibility of heat shrinkage in the outer fabric and is a feature of some of the most recent fusing presses.
- High-frequency fusing: In the fusing press described so far, heat has been provided by electric heating elements. This limits the number of the thickness of fabric which can be fused at once because of the time is taken for the heat to transfer through the fabric to the resin. If multiple layers of fabric and interlining could be stacked up and fused simultaneously, productivity might be increased. Over a number of years, attempts have been made to do this by generating heat by means of high-frequency energy, in the same way as in a microwave cooker
- Hand iron: Only those interlinings which can be fused at relatively low temperatures, low pressures and in relatively short times are at all suitable for fusing by hand iron. There are a number of difficulties.The operator cannot know the temperature at the glue line and cannot apply pressure uniformly. The operator estimates the time subsequently.Only small parts can be fused with any degree of success, and then only by pressing the iron for a fixed time onto the fusible, covering the area step by step and using steam to help the heat transfer.
- Steam press: In this case, fusing takes place on presses of the type used for intermediate and final pressing of made up garments. The temperature at the glue line is achieved by steam from the head of the press.The temperature reached depends on the steam pressure at the press head, the efficiency of the press and its cladding.Pressure is provided mechanically or pneumatically by closing the press head on the buck. The vacuum in the lower part of the press, or buck, assists rapid cooling.
