ABSTRACT:
A method of cutting an elastomeric strip of material is described. The method includes the step of advancing a strip of material2a predetermined distance by a conveyor means30. Resisting reverse movement of the strip2; tensioning the strip2; and cutting simultaneously across the entire width of the strip2through the thickness of the strip2on a skive angle of 45 degrees or less preferably about 28 degrees to form a cut length of material thereby relaxing the tension in the strip as the skive cut ends3and4move apart. This method of cutting can be accomplished by providing an apparatus100for cutting an elastomeric strip of material2which has a frame assembly50, a motorized feed conveyor30mounted onto the frame50for advancing the strip material2, a cutter assembly20mounted on the frame assembly50including a guillotine cutter22oriented to move along a skive angle α, a second conveyor means40for supporting the strip2, the second conveyor means40having rollers42having a one way directional movement in the forward direction resistant to movement in the reverse direction; a motor32connected to the feed conveyor30to drive the conveyor30in an advancing direction and having a reverse tensioning direction; and wherein the cutter assembly20is positioned between the second conveyor means40and the feed conveyor30to cut the strip2after a tension is applied to the strip by reverse motion of the feed conveyor30.
