Abstract
An apparatus is provided for guiding a corrugated cardboard sheet in a transfer portion and machining portion of a corrugated cardboard sheet box-making machine. Eccentric bearing boxes are provided for supporting feed rolls which define a path of travel for the corrugated cardboard sheet. The eccentric bearing boxes are rotatable to adjust the position of the rolls vertically depending on the thickness of the sheet then being run through the machine. The apparatus further includes sheet guide means for guiding the corrugated cardboard sheet to the feed rolls. The sheet guide means includes guide plates supported on brackets which in turn are supported on portions of the eccentric bearing boxes. Adjustment of the position of the eccentric bearing boxes for moving the feed rolls simultaneously effects corresponding adjustment of the position of the guide plates so that a constant difference in level between the guide plates and the upper periphery of the feed rolls is maintained.
