  • Patent number: 8281712
    Abstract: A twist-tie catch twister apparatus is taught that consists of dual feed rollers that feed twist-tie material through a back opening in a catch twister into the groove of a peripheral ring, which continues around the ring penetrating the front side of the catch twister through a second opening. The twist-tie material is then retained by a twist-tie clamp and the rollers reverse rotation drawing the twist-tie material onto a workpiece. The catch twist motor rotates the catch twister one half turn twisting to hold tension on the workpiece. A twist-tie cutter, positioned between the feed rollers and split ring, severs the twist-tie material and the twist-tie tape clamp opens with the motor rotating the catch twister a predetermined number of turns and then reverses at least one half turn to release the twisted material and the split ring opens for removal of the twist-tie secured workpiece.

  • Patent number: 7228795
    Abstract: An existing tying machine (20) is modified by the addition of components to produce a self contained laundry tie-out station (10). The components for the modification include a linear slide support yoke frame (22), attached on top of the tying machine's component mounting platform (24) with a pneumatic linear slide unit (34) mounted on top. A hanger slide rod assembly (40) is attached to the mounting face of the linear slide unit for retaining a selected group of hangers (36) containing laundered clothing (36?). Conveyer feed lines are aligned with distal ends of the recessed hanger slide rod (42) when in an at rest position. A pneumatic system operates the slide unit and controls are integrated into the tying machines existing electrical system. The invention draws the group of hangers into the tying machine where it bunches the hangers together and electromechanically binds the group with a twist tie.

  • Patent number: 7204275
    Abstract: An existing tying machine (20) is modified by the addition of components to produce a self contained automatic laundry tie-out station (210). The components for the modification include a linear slide support yoke frame (22), attached on top of the component mounting platform (24) having a pneumatic linear slide unit (34) mounted on top. A hanger slide shaft assembly (220 or 220a) is attached to the linear slide unit which retains a selected group of hangers with laundered clothing (36?). Gravity conveyer feed lines are aligned with the hanger slide shaft (230) and a pneumatic system operates the slide unit with controls integrated into the tying machines existing electrical system. The hangers are drawn into the tying machine where they are bunched together and bound with a twist tie and then returned to the gravity laundry conveyer system. After the tying is completed a remote signal releases the bound hangers.

  • Patent number: 7011879
    Abstract: A polymeric twist tie 20 is taught that utilizes a thermoplastic monofilament 22 having an oriented characteristic produced by stretching a pre-heated monofilament through a heated, volume reducing die. The monofilament 22 is then coated 30 circumferentially with an extrusion of thermoplastic enclosing the monofilament while simultaneously forming a pair of opposed wings 32 integral with the coating. The wings extend outwardly from the coated monofilament allowing the tie to be twisted upon itself with the monofilament retaining its basic configuration and the wings stretching and bending to conform within a coupled twist. The oriented monofilament is fabricated using high density polyethylene and the covering extruded with low density polyethylene which are dissimilar in density, melt index and basic thermoplastic morphology.
