Abstract
An air box for use beneath a pair of carrier rolls or a roll winder for a web. The air box disposed beneath the carrier rolls has first and second side walls generally sealed respectively at each of the carrier rolls. The paper web passes beneath one of the carrier rolls and up between the rolls. The web may tear and the paper web then drops into the air box. A connecting wall in the air box between the side walls thereof and above the base receives the paper falling thereon rather than the paper falling into the air box. The connecting wall may be inclined to direct the falling paper toward a side wall where an opening is provided enabling the moving of the paper. The connecting wall may be perforated and the air flow into the air box is beneath the perforated wall so that the air flow through the wall cooperates in moving the falling paper along the connecting wall. As a result, the waste paper can be removed quickly and easily.
