Abstract

Apparatus for receiving sheets fed in a first direction and guiding and controlling the sheets through a right angle turn includes at least one right angle turn over module which includes a lower plate with an input belt assembly for receiving the first documents conveyed thereto in a first direction; an upper plate including a 45.degree. turn over section cantilevered above the lower plate, and a turning guide positioned adjacent to the turn over section. The upper plate includes a plurality of output rollers rotatably mounted in the top of the upper plate and oriented for moving sheets at a right angle direction to the first direction. The turning guide includes an upwardly curved edge that extends a fixed distance from the turn over section for guiding sheets around the turn over section. An output belt assembly is suspended above the upper plate for conveying sheets in a second direction that is orthogonal to the first direction. The output belt assembly includes an endless belt moving around at least two rollers and further including structure for applying a normal force to the lower reach of the belt directly above each of the output rollers in the upper plate whereby the upp…
