ABSTRACT:
Grippers or gripper elements are attached at conveyor chain links of a revolvingly driven conveyor chain. The leading edges of each product of an imbricated product formation, in which each product bears upon the next following or trailing product, comes to lie on a clamping jaw of an associated gripper or gripper element and is engaged from above by a clamping element, such as a clamping finger of such gripper or gripper element. The product conveying direction of the transport apparatus and the product conveying direction of an infeed device delivering the products are in the same direction at a product take-over region of the transport apparatus. During the closing motion of the clamping finger of the gripper or gripper element this clamping finger raises a region or portion of the preceding or leading product which covers the leading edge of the trailing product which is to be engaged by such gripper or gripper element.
