Patent DE-19740413-A1 (DE)
Inventor: SCHMELING BURKHARD
IPC: B26D1/00
Filed: 1997-09-10
Abstract: The invention relates to a method for processing tires, producing products comprised of the tire material and a device for cutting tires and flatly constructed products or bodies e.g. blocks, mats or cords which are produced from cut tires. The invention can be applied especially to reshaping passenger car, truck or aircraft tires that are no longer acceptable for use in transportation into a new foundation as a base material which can be utilized for manufacturing products in multiple areas of the economy. Intermediate products for manufacturing new final products are made out of cut tire rings. The method is characterized in that the tires are separated into a series of segments in such a way that the two side pieces of the wheel tread are separated off and the resulting rings are joined to form new products with one another.
