Lesson 14 : Cutting - Notchers

Press cutting

This process involves the use of a hydraulic press (fig 4) which forces a shaped metal cutting die through a pile of material and is mostly used when large quantities of small components have to be cut very accurately. Press cutting is often used for cutting leather and suede garments.

FIG 4 Hydraulic Swing arm cutting Press

In contrast to fast moving blades used, die cutting(fig5) involves pressing a rigid blade through the lay of fabric. The die (called a clicker in shoe industry) is a knife in the shape of a pattern periphery, including notches. Die cutting offers much faster cutting than knife cutting for the same depth of cut. It is proportionally more economic for small parts, which have a greater periphery in relation to their area than the large parts.

FIG 5 Die Cutter

The die press generally has a cutting arm supported by a single pillar at the back of machine. It swings to the side to allow the placing of dies on top of the fabric.
