ABSTRACT:
A collating machine is disclosed in which a reciprocating frame carries a conventional stitcher head and clincher assembly to bind groups of signatures on the fly. A stitcher assembly includes cams and linkages to drive the stitcher head and clincher as the frame reciprocates. Two suspension units guide the reciprocating frame along a substantially linear path. Each suspension unit includes two suspension links and a coupling link. The upper ends of the suspension links are pivotally mounted to the base of the stitcher assembly, and the axes of rotation lie in a horizontal plane. The lower end portions of the suspension links in each suspension unit are pivotally connected with opposite ends of the base of the coupling link. This arrangement enables the coupling link to rock about a central position in which the base of the coupling link includes a pedestal which extends upward from the base of the coupling link and to which the reciprocating frame is connected. The top of the pedestal travels along a substantially straight line path as the coupling link rocks about its central position.
