cut slightly bigger (with 10–30 mm buffers). After fusing, the fine cutting is completed,
and the extra material remaining after fabric shrinkage is removed (see Section 3.7).
It is necessary to control the quality of the fused components throughout the fusing
process. As they are unloaded from the press, the dimensions of the fused components
must be compared with their original pattern pieces (see Fig. 12.1).

12.2.4 The placement of interlining and face fabric components
As textile materials do not have a fixed and stable structure, cut face fabric and in-
terlining components may vary slightly in size that may result in an interlining being
slightly larger than its face fabric component, thus permitting adhesive to get onto the
work surface of the fusing press. The same situation may arise when an interlining
component is not precisely placed onto its face fabric component, and adhesive may
contaminate the work surface and other fused components.
To avoid these problems, the interlining components are cut 3–4 mm smaller than
their face fabric components (see Fig. 12.2). When working with blocks of fusible
components, the interlining material is cut 10–12 mm smaller. These size differences
are created around all contours of the pattern pieces or their blocks or marker during
the making process (see Section 3.7).

12.3 Fusing presses and their main parts

The fusing of face fabric and their interlining components is carried out by special
fusing presses. The fusing presses are divided into two groups according to their work
principles: discontinuous work process (flat) fusing presses and continuous work pro-
cess fusing presses. Discontinuous work process fusing presses work sequentially
