Abstract
Abstract An insert track (30) of an insertion machine comprises a continuous elastomer belt (32) which travels over a horizontal plate (101) and proximate a plurality of insert station hoppers (52H-57H). The plate (101) has an upper surface (103) formed from an ultra high molecular weight (UHMW) polyethylene. The plate (101) is sandwiched in a friction fit between the insertion machine frame (100) and a track front edge guide (105). The plate carries a track rear edge guide (104). In its friction fit the plate (101) is slidable for selectively changing the width of the track from the track front edge guide (105) to the track rear edge guide (104). The track front edge guide (105) has a bridge member (112) connected thereto proximate each insert station (52-57). Each bridge member (112) extends above and across the width of the belt (32). Each bridge member (112) has a drag strip (113) suspendedly connected thereto proximate the midpoint of the belt (32). Each drag strip (113) has an axis of elongation which is parallel to the direction of travel of the belt (32). From its connection to its branch member (112), each drag strip (113) curves downwardly to gently ride on the belt (32). In addition to a feeder (60), each insert station has a pair of knockdown arms (126A), 126B) which direct an item released by the feeder (60) onto the belt (32). Each knock-down arm (126) has a pair of bristled brushes (132, 134) secured to a distal end thereof. The knock-down arms (126) are pivotable about an axis (121). The axis (121) about which the knock-down arms (126) oscillate is intermediate the hoppers (52H-57H) and the belt (32).
