Abstract

An apparatus (22) for clipping ends (128) of a book (20) of sheets comprises a first detector (120, 122, 124, 126) for detecting a first end (128) of the book (20) of sheets, a clipper positioning system (24) and a first clipper (34) including a knife (92). The clipper positioning system (24) is adapted to automatically position the first clipper (34) to a proposed first clipping position based on the detected first end (128) of the book (20) of sheets. A method of processing a plurality of sheets comprises assembling the plurality of sheets into a book (20) of sheets, detecting (120, 122, 124, 126) a first end (128) of the book (20) of sheets to propose a first position (130) for clipping the book (20) of sheets, positioning a first clipper (34) based on the detected first end (128) of the book (20) of sheets, advancing the book (20) of sheets to an infeed conveyor (156, 160, 164, 166, 168, 170), detecting (120, 122, 124, 126) the presence of the book (20) of sheets in the infeed conveyor (156, 160, 164, 166, 168, 170), advancing the book (20) of sheets to the first clipper (34), clipping the first end (128) of the book (20) of sheets, and advancing the book (20) of sheets from the first clipper (34).

Abstract

A method and apparatus for making a piece of figured veneer comprise means for, and the steps of, softening lignin in a sheet of veneer, pressing the sheet of veneer between complementary corrugating press rollers having a pitch and a depth to press the sheet of veneer into a wavy or corrugated configuration, and surfacing the pressed sheet of veneer to remove crests of the corrugations, making the piece of figured veneer. Another method and apparatus for making a piece of figured veneer, comprise means for, and the steps of, softening lignin in a sheet of veneer, placing the sheet of veneer onto a wavy or corrugated surface of a plate, pressing the sheet of veneer using a press roller so that the roller presses the sheet of veneer against the surface to achieve a wavy or corrugated veneer, and surfacing the pressed sheet of veneer to remove peaks of the corrugations, making the piece of figured veneer. Yet another method and apparatus for making a piece of figured veneer, comprise means for, and the steps of, softening lignin in a sheet of veneer, placing the sheet of veneer onto a corrugated surface of a plate having such a wavy or corrugated surface, pressing the sheet of veneer onto the troughs and peaks of the surface using a flexible platen having a corrugated surface so that the corrugated surface of the platen presses the sheet of veneer against the corrugated surface of the plate to achieve a wavy or corrugated veneer, and surfacing the pressed sheet of veneer to remove peaks of the corrugations, making the piece of figured veneer.
