Abstract
A bed for supporting sheet material to be cut or otherwise worked on is made of a densely packed array of relatively short, stiff bristles with pointed upper ends which penetrate the sheet material to inhibit it from moving laterally relative to the bed. Vacuum may be used in the space containing the bristles to aid in holding the sheet material to the bed and to normalize the holding effect of the bristles with respect to different sheet materials. Pressurized air may also be used in the bristle space to aid in removing cut sheet material from the bed and the bristles are shaped to facilitate such removal. Various different cutters are useable with the bed to provide a complete sheet material cutting machine.
