PROCESS AND APPARATUS FOR BUILDING TYRES

摘要

A continuous elongated element (21) of elastomeric material is produced through an extruder (22) at a linear delivery speed (Vi) and directly fed onto a moving surface (31) of a conveyor (30) without interposition of other devices. The continuous elongated element (21) is advanced on the moving surface (31) along a predetermined direction (X) and at a linear advancing speed (V2) different from the linear delivery speed (Vi), until a proximal end (32) of the conveyor (31). Subsequently, the continuous elongated element (21) is applied onto a forming support (16) which rotates relative to the proximal end (32) of the conveyor (30) at a peripheral speed (V3) different from the linear delivery speed (Vi), so as to deform the continuous elongated element (21) and apply it in the form of wound coils onto said forming support (16), in order to form a component of elastomeric material of a tyre (3).
