Brief description of the joint of a layer of material to the embodiment of a roughing raw tire

摘要

The present invention relates to a process for the seal of an outer layer (12) of material on a base layer (14) for the production of a green tire, the blank having an axis of revolution (x), the method comprising a step of application of the outer layer (12) on the base layer (14), followed by a joint of the outer layer (12) against the base layer (14). The gasket is effected by means of an attachment element (18) surrounding the outer layer (12) and elastically deformable between a configuration called an enlarged scale, and a configuration of the application of the outer layer (12), in which the attachment element (18) exerts a radial pressure on the outer layer, the gasket comprising the following steps: - - passage of the attachment element (18) of the configuration shown enlarged in the configuration of the pressure of the layer, - - displacement, along the axial direction (x) of the blank, the attachment element (18) in the configuration of the plating.
