Abstract
A Layboy machine for the transportation of corrugated boxes including one or more Scrap Separation devices for improved Scrap separation. The Scrap Separation means include a Compliant Scrap Blocker for Loose Scrap, an Opposing Phase Shift Beater for Trapped Scrap and all types of Hanging Chads, a Chad Wall for stripping Lead Edge Trim, Trail Edge Trim and Side Edge Trim Scrap, a Compliant Scrap Blocker-Wedge Roller for harsher scrubbing of the box and motivating Scrap above the Board Line to move to under the Board Line and Side Edge Trim Chad Stripper which is removes Side Edge Trim Chads. The Wheel Assemblies are superior in allowing the proper configuration of the various Scrap Separation Means. The concept of the staggered Wheel Assemblies also leads to reduced Order Setup Time, better board control and reduced Print Damage and Box Size variation out of the Press.
