ABSTRACT:
The invention relates to a method of conveying flat, flexible products, in particular printed products, in which the products are conveyed continuously by means of a conveying device in an overlapping formation to a transfer region and are picked up there by an outward conveyor. The outward conveyor comprises grippers which are moved along a movement path, can be controlled individually to open and close and have at least two gripper jaws, whose alignment relative to the movement path can be varied. According to the invention, the grippers are moved in such a way that the gripper jaw facing the conveying device engages in the manner of a shovel underneath the trailing edge of at least one product resting partly on the trailing product in the transfer region, without said product having previously been raised off the trailing product, and then raises said product. The products, before or after being engaged underneath, are braked relative to trailing products and/or fixed in their position. The invention also relates to an apparatus for implementing the method.
