ABSTRACT:
On the conveyor track (1) on which the objects (2a, 2b) to be turned are moved at an equal distance apart by slides (3a, 3b), there is provided along a turning zone an advancement mechanism having an advancement member in the form of a spring bar (5), which is periodically moved, at an accelerated speed relative to the speed of conveyance, forward out of an initial position into an end position and back again into the initial position. The spring bar (5) disposed over the conveyor track (1) has a bent section (5b) which reaches down to the conveyor track and the concave side of which points in the direction of conveyance. Between the two aforementioned positions of the spring bar (5), there are fastened on the conveyor track (1) two stops (6) which are aligned in the transverse direction and the height of which is less than the height of the object and the side of which pointing oppositely to the direction of conveyance exhibits in its upper region an inclined face (6a). Thee arrangement is made such that an object (2b) isunder-gripped at its rear edge by the end (5c) of the bent spring section (5b), pushed forward at an accelerated speed against the stops (6), then raised up at the rear and, guided within the bent spring section, tilted forwards over the stop and deposited, turned under the influence of the spring force of the spring bar, on the conveyor track, whereupon it is taken up again by the original slides (3a).
