  • Method and machine for removing at least one layer of reinforcing elements from a breaker or belt of a rubber tire
    Patent number: 4825926
    Abstract: This invention relates to a method and machine for removing at least one layer of reinforcing elements from a breaker or belt of a rubber tire.According to the method of the invention for removing at least one layer of reinforcing elements, such as steel cords, etc. from a breaker or belt located between the tread area and the carcass of a rubber tire; the tread area of the tire is first removed down to the layer of reinforcing elements by rasping off this tread area, and afterwards each reinforcing element, for example each steel cord, of the layer to be removed is cut through in at least one place and the so cut reinforcing elements are removed by further rasping.This invention further relates to a machine for carrying out this method.

  • Machine for retreading pneumatic tires
    Patent number: 4670082
    Abstract: This invention relates to a method for applying a tread to a tire, whereby around a toroidal tire a layer of non-vulcanized rubber is applied, which will form the tread area of the tire after vulcanization in the vulcanization press; and whereby the thus prepared tire is vulcanized in vulcanization press. According to the invention, before the vulcanization of the thus prepared tire in a vulcanization press, portions of the layer of non-vulcanized rubber are removed by peeling or by forming peels of non-vulcanized rubber, so that the shape of the peeled tire is adapted to the shape of the vulcanization press. The invention also relates to a machine for carrying out the method according to the invention.
