    摘要: Method for winding a rubber strip (24) onto a form of revolution (46), in which a strip (24) of predetermined length is formed, front-edge and rear-edge markings are applied thereto, and it is entrained toward the form (46), the front edge is placed on the form (46) and the form (46) is driven in such a way as to wind the strip (24) onto the form (46). During a first step, the drivings of the strip (24) and of the form (46) are synchronised in such a way as not to alter the length of the strip. During a second step, these drivings are controlled according to the angular position of the form (46) at the end of the first step and according to the position of the rear-edge marking so as to cause the relative speeds of travel of the rear-edge marking and of the rear-edge marking to vary and compensate for variations in the length of the strip (24).
