Abstract: A tufting machine having individual crank assemblies for reciprocating the push rods which carry the needle bar. Successive crank shafts aligned with each other and parallel to two main drive shafts which are rotated in opposite directions. Gears on the main drive shafts respectively transfer power from the two drive shafts so as to rotate each successive crank shaft in a direction opposite from the direction of rotation of the preceding crank shaft. The connecting rods connected to the crank assemblies thus are thrown outwardly in opposite directions as the crank shafts are rotated, so as to balance the machine. Additional counter-balance weights are provided on the main drive shafts.

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).

Abstract: An insertion machine includes an insertion station (44) whereat groups of items are stuffed into an envelope held open at an envelope opening station (49). The insertion station comprises an cam (212)-driven carriage (202) which linearly reciprocates in a direction (480) toward and away from the envelope opening station (49). The carriage (202) carries a plurality of selectively mounted, selectively rotatable pusher fingers (204). The pusher fingers (204) have a profile suitable for shoving items along a partially inclined insertion plate surface 403 and into an opened envelope. The pusher fingers (204) are selectively rotatable to an operative orientation (720) and to an inoperative orientation (722) under the supervision of a controller (205). Jam detectors (550, 552) are provided proximate reciprocating entry fingers (500, 502) which move when a jam occurs in the inserting process. Should a jam occur, the pusher fingers (204) are controlled to rotate to their inoperative orientation (722).

Abstract: Apparatus and method for automatically preparing large mailings in which one or more documents are nested within the fold of a letter sheet prior to insertion into an outer envelope. One or more unfolded letter sheets are transported to a folding operation involving a clamp assembly and a roller folding assembly which is movable into engagement with the clamp assembly. After folding and prior to stuffing into an envelope, one or more inserts can be inserted within the folded letter sheet.

Abstract: Both positive pressure fluid and negative pressure fluid are used in a method and by an apparatus to at least partially separate a sheet prior to the feeding of the sheet. A carriage 22 having registration arms 160 resiliently coupled thereto is rotated toward a sheet lying in a storage position in a hopper 200. The carriage 22 bears both a positive pressure-communicating port 54 and negative pressure-communicating orifice, preferably in the form of two bellows-type sucker cups 56A, 56B. Positive pressure fluid is applied through port 54 in a manner whereby at least a portion of sheet 220 is attracted to a surface 52 in which ports 54 lie. While positive pressure fluid is being applied, the carriage 22 is rotated away from the storage position of the sheet 220, thereby deflecting at least a portion of the sheet about a first axis 208 of the sheet 220.
