ABSTRACT:
Described is a method of joining a belt-tread assembly with a carcass assembly by stitching in green tire production such that a pressure is applied in radial inward direction on the rotating outer peripheral surface of a belt-tread assembly (5) partially joined with an inflated carcass assembly (1) of a tire, which is disposed on a tire building drum, the pressure being exerted by inelastic force of at least two stitching rollers (2) which are rotationally and inelastically disposed on a rigid bearing part (3) of the stitching unit. The rigid bearing part (3) is provided with means for mutual symmetrical axial movement in the direction of arrow (6) of the stitching rollers (2) from the central part of the outer peripheral surface of the belt-tread assembly (5) of the tire being produced to its shoulders, with means for moving the rigid bearing part (3) along an axis perpendicular to the rotation axis of the tire being produced, and with means controlling rotational position of the stitching rollers (2) in the direction of arrow (7), the compressive force of the rollers (2) being controlled by the means for moving the rigid bearing part (3) in the direction of an axis perpendicular to the rotation axis of the tire being produced. Also a device for accomplishing the method is described.
