Loading device for loading green tires into a curing press

摘要

A loading device (5) for loading green tyres (3) into a curing press (4). The loading device (5) has a horizontal turntable (6) having a number of supports (7) for supporting green tyres (3) for curing; a vertical shaft (13) rotating about a vertical axis of rotation (8) and supporting the turntable (6); and an actuating device (9) having a motor (14) connected to the shaft (13) to rotate he turntable (6) in steps about the axis of rotation (8). The actuating device (9) has a variable-pitch worm (15) rotated by the motor (14) and having a zero-pitch portion; and a follower (16) fitted coaxially to the shaft (13) and engaging the worm (15) so that rotation of the worm (15) produces a corresponding rotation of the follower (16) about the axis of rotation (8) by an amount directly proportional to the pitch of the portion of the worm (15) engaged by the follower (16).
