Abstract

Proposed is a paddle belt design that provides two key elements in trim waste removal. The design breaks a mechanical bond and then wipes an upper and a lower knife during the cutting process. The design also minimizes trimmings from migrating above the lower knife assembly so as to reduce waste trimmings during a book making process. As shown in the accompanying figure, the proposed paddle belt design is comprised of a pair of paddles 20 fastened to an input transport belt 22. The input transport belt 22 travels in a direction indicated by arrow 24 to move a book 30 to a position on a trimming station 34. Normally, the paddles are folded down on the horizontal plane of belt 22. After the book 30 is registered and in place for trimming at trimming station 34, an upper knife 26 begins a downward cutting stroke of a reciprocating movement indicated by arrow 25. At the radial turn of the belt 22 around pulley 36, paddles 20 flip in an outwardly direction so as to create a wiping across the upper knife 26 and the lower knife 28. The wiping action, in turn, cleans waste trimmings 32 from the knives 26 and 28. Trimmings 32 then exit via an exit chute 34.
