Abstract:
1. An assembly for lapping a first sheet of material with a consecutive second sheet of a material, comprising: a first roll rotating at a first speed for conveying sheets of material along a feed path; a second roll positioned adjacent the first roll along the feed path and rotating at a second speed; and a roller assembly positioned proximate the second roll along the feed path such that a nip is defined with the second roll, wherein the first roll feeds a sheet of material along the feed path such that the leading end of the sheet is fed into the nip while maintaining the sheet in engagement with the first roll and wherein the nip engages the leading edge of the sheet with the second roll while the trailing edge of the sheet remains in engagement with the first roll; and wherein the roller assembly is movable relative to the second roll so as to vary the location of the nip relative to the surface of the second roll.
