Abstract

Trim waste from a booklet maker contaminates belts, affects switches and migrates through a printing machine and office environment. Proposed is the utilization of low resistance static brushes to wipe trim material from a cutting blade. As shown in the accompanying figure, the trim waste control comprises a pair of mounting brackets 21 and brushes 20 mounted thereto. Mounting brackets 21 serve as safety guards for both sides of an upper knife 26. A transport belt 22 travels in a direction indicated by arrow 24 to move a book 30 to a position over lower knife 28. After the book 30 is registered and in place for trimming, upper knife 26 begins the downward stroke of a reciprocating movement indicated by arrow 25. At the radial turn of the belt 22 around pulley 36, brushes 20 wipe upper knife 26 to clean trimmings 32 from knife 26. Trimmings 32 then exit by way of an exit chute 34.
