Abstract
A device for feeding packaging blanks (3) to a packaging machine has a magazine with two shafts (7) mounted at the bottom for supporting the blanks (3). The shafts (7) are brought to rotate at constant speed in opposite directions to each other, hence eliminating the static friction from the bottom of the magazine. An angle is formed between the shafts (7), so that a small, forwardly directed force component contributes to the movement of the blanks (3). The dynamic friction is used to move blanks (3) towards a gate (2) at the end of the magazine, and only a small, constant feeding force (A) from a pusher is necessary for the movement.
