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.
Cutting apparatus for cutting into sections a profile strip of rubber mixture which is transported by a conveyor which is stopped intermittently for making a cut, said apparatus comprising a frame, a circular knife secured on a knife shaft, bearing means for rotatably supporting said knife shaft and knife, supporting means for supporting said bearing means on said frame, transverse motion means for moving said bearing means, knife shaft and knife transversely of said profile strip, height positioning means for positioning said bearing means, knife shaft and knife at a lower height during movement of said bearing means, knife shaft and knife transversely of said strip in one direction for effecting a cut of said strip and for positioning said bearing means, knife shaft and knife at a higher height during return movement of said bearing means, knife shaft and knife in an opposite direction,
Cutting apparatus for cutting into sections a profile strip of rubber mixture which is transported by a conveyor which is stopped intermittently for making a cut, said apparatus comprising a main frame, a seesaw frame pivotally mounted on said main frame for tilting about a horizontal axis and having an upper end portion and a lower end portion,
