Patent ID: 7887050

Claim:
A right angle turn module for processing multi-sheet collations, comprising: opposed belt segments defining a conveyance channel for capturing multi-sheet collations therebetween and for conveying multi-sheet collations from an input end to an output end of the conveyance channel, the opposed belt segments defining: a first re-directing bend including a rolling element for re-directing the opposed belt segments about a first axis of rotation; a second re-directing bend including a rolling element for re-directing the opposed belt segments about a second axis of rotation; the first and second axes of rotation being orthogonal and lying in a parallel plane so as to effect a twist section therebetween; an anti-skew guide having a spiral-shaped guide surface for engaging a leading edge portion of a multi-sheet collation to maintain a desired orientation thereof for alignment of the multi-sheet collation and subsequent insertion into a mailpiece envelope; and a mechanism for driving the opposed belt segments about the first and second re-directing bends to convey the multi-sheet collations from the input to output ends and effect a right angle turn of the multi-sheet collations.
