APPARATUS FOR CUTTING PROFILE STRIPS FORMED OF RUBBER MIXTURES ABSTRACT OF THE DISCLOSURE: Apparatus for cutting profile strips of rubber mixture produced by extrusion and/or calendering and transported to the cutting apparatus by a conveyor which is intermittently stopped for making a cut has a motor driven rotating knife which is moved transversely of the profile strip by a roll-ring drive and is raised to a height above the profile strip for return movement of the knife. In one embodiment, the knife, its driving motor, and the mechanism for moving the knife transversely of the profile strip are mounted on a seesaw which is pivoted on horizontal axis and is moved pivotally by a pneumatic servo-motor to raise and lower the knife. In other embodiments the knife and transverse movement mechanism are mounted on a movable carriage, which is raised and lowered by a pneumatic servo motor while the motor for driving the knife in rotation is mounted on the frame of the apparatus and connected to the shaft of the knife by a flexible or telescopic connecting shaft. The carriage runs on a track or is supported by a parallelogram linkage. b:WSS/6020-4/abstract/May 21.92/sm w:201
