ABSTRACT:
An apparatus for separating one or more essentially thin and planar products (3), such as books, periodicals and newspapers, from a stack (2) of such products. The apparatus includes a gripping arrangement (6) for gripping of at least one product (3) at a time at the top of the stack (2), and for lateral movement of the product to engagement with a further-feeding transport apparatus (7), and a threshold construction (14) forming an abutment against the products (3) below the product to be separated at a time, and which has a slot opening (15) having a height (H) allowing the passing of only said at least one product at a time. The threshold construction (14) is connected to a position sensor (20) sensing the top level of the stack (2) and giving a signal to a regulator (5) and the regulator controls a stack-supporting hoisting mechanism (1), so that the hoisting mechanism raises the stack (2) to the correct top level in relation to the threshold construction.
