ABSTRACT:
A machine and method of using same for cutting soft sheet material, such as textile fabric, which includes a cutting table having a support surface with openings distributed thereover. An endless conveyor of relatively high air permeability overlays and is movable relative to the support surface for moving sheet material. An endless micro-porous support belt having a relatively low air permeability overlays the conveyor for corresponding movement therewith. A vacuum source is connected to the cutting table and cooperates with the micro-porous support belt to retain the sheet material thereon in a relatively fixed position during transporting and cutting thereof and to retain the micro-porous support belt in engagement with the conveyor for uniform movement therewith. A cutting tool is supported on a cutting table for cutting the sheet material. The cutting tool has a washer positioned adjacent the cutting wheel to limit the penetration of the cutting wheel in the micro-porous support belt. An indexing device is provided to cooperate with the cutting tool for locating the position of the sheet material prior to cutting thereof.
