Method and device for cutting to length a strip of tire building material

摘要

A method for cutting to length a strip of tire building material includes the step of feeding the strip of tire building material via a conveying device tangentially to a winding drum. In a further step the strip of tire building material is wound onto the winding drum by rotating the winding drum and a defined pressure is simultaneously applied with a pressure roller during winding until a length of the strip of tire building material corresponding almost to the circumference of the winding drum has been wound onto the winding drum. The rotating winding drum is then stopped and the strip of tire building material is fixed in a first location in the vicinity of a cutter bar that is positioned directly in front of the conveying device. The pressure roller is then moved from its initial position toward the cutter bar along the circumference of the winding drum to thereby tighten the strip of tire building material and fix the strip of material in a second location closely adjacent to the first location. In a final step, the strip of tire building material is cut with a cutting tool.
