EXTRUSION APPARATUS AND METHOD

EXTRUSION APPARATUS AND METHOD

ABSTRACT The extrusion of a tire sidewall or tread and sidewall strip with a white sidewall stripe integrally formed therewith is made possible by an improved, modified preform unit. The preform unit has a first passageway for the sidewall or tread-sidewall strip that extends from the entrance side through to the exit side of the unit. The unit is modified to include a second passageway for the white sidewall material that introduces the white material into the stream of the black sidewall material as it passes through the unit. Upstream of the point where the white side material is introduced, the blockage means interrupts the flow of the black material, creating a void in the stream into which the white material can flow.

A carcass structure (3) of a tyre (2), previously formed on a building drum (14) is mounted on a primary drum (15), while a belt structure (4) is being made on an auxiliary drum (16). The primary drum (15) is supported by a robotized arm (21a, 21b) causing translation of said drum starting from a position at which it interacts with a member for transfer of the belt structure (4) onto the carcass structure (3), in order to sequentially submit it to the action of extruders (19, 19a, 20) each of which delivers a continuous strip-like element of elastomer material. Movement imparted to the primary drum (15) by the robotized arm (21a, 21b) in front of each extruder (19, 19a, 20) causes distribution of the strip-like element in circumferential coils disposed in side by side relationship, to form a layer of the desired thickness and geometric conformation for obtaining the sidewalls (6) and/or the tread band (5) of the tyre being processed. © KIPO & WIPO 2007 ...
