ABSTRACT:
A hand held portable twist tie apparatus which has a frame (20), a drive motor (44) and controls. A set of reduction drive gears (68) reduce the motor speed and drive a gear cluster with turntable (74). A twister (94) is rotated by a drive train (114) that intermeshes at the proper time with the gear cluster. A spring loaded shuttling carriage (126) slides along the twister and contains arms (130) that swing around the product and guide twist tie material (76) to enclose the product to be tied. A feed transport arm (142) advances the tie material and cuts it to the appropriate length for complete encircling, tightening and twisting by the above elements. A housing (208) and shield (210) cover the moving parts and a reel holder (194) mounted on top of the housing accepts a roll of tie material to supply the apparatus. A handle (218) provides a grip for one handed operation and power is supplied by a battery (48), or power converter (58).
