Abstract

A device for cardboard storage and removal for a bridge in a corrugated cardboard production line includes a bridge over which a conveyor system for conveying the single-sided laminated corrugated cardboard web is arranged. The exit end of the conveyor system for conveying the single-sided laminated corrugated cardboard web is provided with a clamping and cutting unit and a movable cardboard storage carriage unit is provided under the conveyor system for conveying the single-sided laminated corrugated cardboard web, under which conveyor system a conveyor belt system is provided in the bridge, and in the bridge an opening is provided, under which a waste cardboard collecting carriage is provided. The movable cardboard storage carriage unit stores the cardboard by means of cardboard storage rolls, which retain the single-sided laminated corrugated cardboard web flat on the bridge. In the event that a splicing defect is detected, the defective piece is cut out by the clamping and cutting unit and ejected by the conveyor belt system to the waste cardboard collecting carriage through the opening. Hence, it follows that productivity is improved.
