Apparatus for cutting sheet material with a cutting wheel

摘要

An automatically controlled cutting machine for cutting sheet material employs a cutting wheel and a hard, smooth and continuous surface of ferromagnetic material on which the sheet material is spread for cutting. To prevent shifting during cutting, the material is releasably attached to the support surface by adhesives, freezing, electrostatics and other securing means. The cutting wheel is forced downwardly against the hard support surface by an electromagnet mounted on the cutting wheel support to insure severing of the sheet material.
