Abstract
A gripping unit for gripping a paper from a top surface of a stack includes a first and a second friction wheel having rotation axes that are mainly parallel with respect to each other. The friction wheels are arranged to exert a friction force on sections of a paper. Further, the gripping unit comprises an actuator on which the first friction wheel is mounted for moving the first friction wheel towards the second friction wheel. The first friction wheel is arranged to rotate with respect to its axis during the movement towards the second friction wheel such that a paper section on which the first wheel exerts the friction force is forced into the direction of the second friction wheel.
