ABSTRACT:
The present invention relates to equipment used in a printing system for newsprint or the like, more specifically, to a device for successively rolling up unusable outer surface strips from paper rolls, compressing them, and then discharging them. The device comprises first and second conveyors which can be moved between a V-shaped position, wherein unusable paper is conveyed in a forward direction and rolled up into a cylindrical shape, and parallel positions, wherein the rolled-up, unusable paper is compressed flatly and discharged. A semi-arched guiding device disposed above the two conveyors cooperates with the conveyors to roll up the unusable paper into a cylindrical shape and one of the conveyors changes its conveying direction to switch from a rolling up mode to an ejection mode.
