Tire component cutter apparatus and method of cutting

摘要

A method of cutting an elastomeric strip of material is described. The method includes the step of: advancing a strip of material (2) a predetermined distance by a conveyor means (3); resisting reverse movement of the strip (2); tensioning the strip (2); and cutting simultaneously across the entire width of the strip (2) through the thickness of the strip (2) on a skive angle of 45 degrees or less to form a cut length of material thereby relaxing the tension in the strip as the skive cut ends move apart. This method of cutting can be accomplished by providing an apparatus (100) for cutting an elastomeric strip of material (2) which has a frame assembly (50), a feed conveyor (30) mounted onto the frame (50) for advancing the strip material (2), a cutter assembly (20) mounted on the frame assembly (50) including a guillotine cutter (22) oriented to move along a skive angle ±, a second conveyor means (40) for supporting the strip 2, the second conveyor means (40) having rollers (42) having a one way directional movement in the forward direction resistant to movement in the reverse direction and; a motor (32) connected to the feed conveyor (30) to drive the conveyor (30) in an advancing direction and having a reverse tensioning direction; wherein the cutter assembly (20) is positioned between the second conveyor means (40) and the feed conveyor (30) to cut the strip (2) after a tension is applied to the strip by reverse motion of the feed conveyor (30).
