ABSTRACT:
An automatically controlled cutting machine includes a conveyor table having an endless conveyor belt for moving segments of limp sheet material onto the table for cutting. A cutting carriage and blade are mounted for controlled movement over the support surface of the table to cut pattern pieces from the limp sheet material positioned on the surface. A vacuum chamber envelops the endless conveyor belt except for the portion of the belt defining the support surface, and the chamber communicates with the sheet material on the surface to draw a vacuum within the material and hold the material in a compressed state on the surface for cutting.
