ABSTRACT:
A cutting machine having a reciprocating cutting blade is provided with a penetrable support bed for holding limp sheet material during a cutting operation. The support bed is formed from a plurality of flexible bristles held in a closely packed array. The base ends of the bristles are mounted in a binder and the free ends of the bristles have flattened heads which lie in a common plane defining the support surface on which the sheet material is spread. The flattened heads are developed by heating the free ends of the bristles in the array until they are softened and then forming the heads on the free ends. The bristles are preferably made of a thermoplastic material.
