Abstract

An apparatus for making relief cuts on prescored glass sheets is disclosed, having an elongated beam extending above the previously scored glass pane; a horizontal, pressure medium operated cylinder and piston unit disposed on the beam and extending substantially over the entire length thereof to advance the cutting wheel to a starting position adjacent the previously scored outer contour of the pane, and then to effect the relief cut; a cutting head which bears the cutting wheel and can be displaced horizontally by the horizontal cylinder and piston unit; a vertical, pressure medium operated cylinder and piston unit disposed in the cutting head for raising and lowering the cutting wheel out of and into its working position, and a control system for the controlled, automatic operation of the cylinder and piston units.

Dependent claims

An apparatus for making relief cuts on pre-scored glass sheets, comprising:

elongated support means, first cylinder and piston means supported by said support means, cutting head means reciprocable by said first cylinder and piston means along said elongated support means in a first plane, a cutting roller carried by said cutting head, second cylinder and piston means arranged at said cutting head for moving said cutting roller relative to said support means in a plane substantially perpendicular to said first plane, and means for controlling said first and second cylinder and piston means, whereby said cutting roller is adapted to be moved into a starting position adjacent the pre-scored sheet by said first cylinder and piston means moving in one direction in said first plane, said roller moved to a cutting position by said second cylinder and piston means, and said sheet relief-cut by said cutting roller in said cutting position during movement of said first cylinder and piston means in said first plane in a direction opposite to said one direction.
