Abstract: An insert track (30) of an insertion machine comprises a continuous elastomer belt (32) which travels a horizontal plate 9101) 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).
