摘要:
A cutting apparatus employs a cutting wheel which is rotated about an axis perpendicular to a support surface on which sheet material is positioned for cutting. A stripping plate is mounted in closely spaced relationship with the cutting wheel so that shredded material generated by the wheel during a cutting operation is sheared off. The cutting wheel in a cutting operation is advanced relative to the sheet material so that the leading cutting edges of the wheel, rather than the trailing edges, move along the desired line of cut. The material being cut is positioned on a bed that can be penetrated by the wheel and the depth of penetration of the wheel into the bed is regulated to remain substantially constant as the tool moves along the line of cut.

A machine for trimming the backing sheet of a composite product having an open network fabric secured to a backing sheet includes a support for holding the product, and a movable separator bar having laterally spaced apart fingers for separating the sheet from the fabric along one edge of the product. A carriage moves a cutter bar between a cutting position adjacent the separated portion of the sheet and a clear position. The carriage also includes a blade which is movable relative to the cutter bar. The sheet is disposed between the blade and the cutter bar when the bar is in the cutting position, and the blade is actuated to cut the sheet once the bar is in the cutting position.

A machine for processing scrap metal having a shear arm rotatably mounted on a machine body and having a drive motor operatively connected thereto for driving the arm relative to the machine body to effect a shearing action on the scrap metal. Cooperatively associated with the shear arm is a driving ram member, to compress the sheared scrap metal into a compact form upon operation of the shear arm. In operation the scrap metal is first caused to be sheared by the operation of the shear arm and then compressed into a compact block by the action of the ram.
