12.3.2.6 Mini (compact) continuous work process fusing presses

As continuous work process fusing presses deliver higher productivity and lower
power consumption, is more versatile than discontinuous work process presses, they
are also designed for use in small production units. Compact fusing machines with
narrow conveyor belts can be opened at one side to allow the partial fusing of wide
components (the components are fused one side at a time). This is particularly useful
for fusing smaller areas on larger fabric pieces. Compact size presses may have a spe-
cial return belt system that provides for the return of fused components to a location
where they can be loaded and unloaded by a single operator.
Available accessories for compact presses are as follows: unloading slides (for easy
removal of the fused parts and to prevent their deformation during the unloading pro-
cess), base frames (to widen the work surface during partial fusing of components),
waistband fusing devices, and stackers.

12.3.2.7 Large (high power) continues work process fusing
presses

Large fusing presses are designed for high-power units producing men's and women's
jackets and coats. They may be equipped with the following:

A large number of heating zones to meet the requirements of various kinds of fusible
●
fabrics.
A double-pressure system with two pairs of pressure rollers to improve the pressing quality.
●
Autodiagnosis systems to monitor the heating, pressure, and belt regulation.
●
Three-dimensional heating systems to fuse different components in three separate lines at
●
three different temperatures.
Accessories for high-power fusing presses include feeding conveyors with several
loading belts and multifaceted collecting stackers that automatically recognize, sort,
and bundle different groups of fused components.

12.3.3 Fusing presses for men's shirts
Men's shirts are washed more frequently than most other garments and must have
a laundry resistance of up to 95°C. Thus, the quality of the fusing process and the
presses are important. There are several specific requirements that must be taken into
consideration when fusing the components of men's shirts (collars, cuffs, and front
plackets):

Shirt fusing requires very high glue-line temperatures because of the special interlinings.
●
Nearly all adhesive resins for shirts also require high pressure to produce strong bonds.
●
The fused components of shirts have to be intensively cooled.
●
Many companies have developed special continuous and discontinuous work pro-
cess shirt fusing presses. These are compact in size and ensure high and stable tem-
peratures of up to 210°C, high pressure, and special intensive cooling systems (air
blowing or water cooled) on their exit conveyors.
