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.

Abstract: The invention concerns an assembly of devices for production of green radial tires, comprising a carcass building drum (11), a belt building drum (21) and a completing drum (22), which are arranged on one horizontal axis, wherein the carcass building drum (11) and the belt building drum (21) are equipped with the respective supply systems (4, 5), the carcass building drum (11) is carried by a driving unit (1), and the belt building drum (21) and the completing drum (22) are carried by co-axially arranged shafts of a driving unit (2), which is arranged opposite the driving unit (1) carrying the carcass building drum (11), and between the belt building drum (21) and the carcass building drum (11) there is movably arranged only one transfer device (3). The invention further concerns a method of production of green radial tires using the above assembly.
