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.
