Abstract (en)
[origin: CA2368735A1] Flat articles (3) each held by a feeding-in gripper (5) on a leading first edge are fed-in to a hold changing station (1) one after the other, are pulled onto a changi ng support situated in the changing station (1) and are deposited on it by opening the feeding-i n gripper (5). Each deposited article is then pushed across he changing support (10) by a conveying-away gripper (6) and while being pushed is grasped by closing the conveying-away gripper (6) and is conveyed away held gripped on a second edge. Advantageously the feeding-in direction (Z) and the conveying-away direction (W) intersect above the changing support (1 0) under the one angle (a), which is also constituted by the first and the second edge. F or the hold change of rectangular printed products, the angle (a) amounts to 90.degree.. For pushing the articles, the conveying-away grippers (6) move in the plane of the surface of the changing support and are driven from below. For articles (3) which overlap one another on being fed-i n; the feeding-in grippers (5) move above the surface of the changing support (10) and are driven from above. The hold changing operation can be implemented with simpler means than known hold changing operations. Nonetheless the security and the accuracy, with which t he change is carried out are satisfactory for most requirements.
