A method for reducing the tack of an unvulcanized green tire tread strip arranged on a

摘要

In order to provide a method with the rubber adhesion to the vulcanization mould position in the case of the tire vulcanization be largely avoided, the following method is proposed with the following steps:a) providing a green tire (3) with a tread strip (1) from an elastomer in a retaining device -,b) applying a solution (4) with a catalytic converter - means to the surface of the unvulkansierten tread strip (1),the catalyst - means to a premature crosslinking of unvulcanized rubber material and is matched with the solution of the surface of the unvulkansierten tread strip (1) is substantially completely wetted,c) irradiation of the tread strip (1) with an irradiating device (6),the tread strip (1) a relative movement with respect to the irradiating device (6) is carried out,with the irradiation of the surface of the unvulkansierten tread strip (1) the chemical reaction of the catalyst - by means of in connection with the uppermost layer of the rubber material is initiated,wherein by the chemical reaction of a premature crosslinking of the polymers in the topmost layer of the rubber material takes place,as a result of which the tack as well as the viscosity in the topmost layer of the unvulkansierten tread strip (1) to be substantially reduced,d) removal of the green tire (3) with the pretreated tread strip (1) from the hold - device,e) vulcanization of the green tire (3) with a conventional e.g.
