摘要

Guide slots are fitted for the supply of the folded boxes which end in an outlet opening. The folding boxes are moved separately one behind the other folded down in and along the guide slots with their folding edges positioned transverse to the direction of the slot. A stop parallel to the folding edges is located transverse to the outlet openings at a clear distance equal to the length of the folded down folding boxes vertical to the folding edges which catches the foremost folding edge of the box during its exit from the guide slots and holds it in a diagonal vertical to the folding edges and prevents a sliding off transverse to the diagonal plane running through these two folding edges. The installation also includes drivers adjoining each folding box coming out of the guide slots which move to reduce the distance between the drivers and the stop which produces the pre-breaking, erecting and breaking beyond the vertical movements.
