Profiled rubber strip (20) is fed from an extruder to an endless conveyor belt (5), which places the strip on to a winding drum. The belt is carried on an arm (39) with a rotary joint (40) so that the end roller (32) that deposits the strip can be twisted relative to the drive roller (31). The arm is mounted on a winding head (4), which can travel and rotate. The head (4) also carries another similar arm for constructing the other side of the tire. Calender rollers (7, 8) are placed above the conveyor (5). The positions of the depositing rollers (32, 42) are controlled (30) to follow the build-up of the two sides of the tire on the drum. The strip is cut to length by pneumatically actuated cutters (10, 11) while held in pneumatic grippers (16, 17). |
