A first gripper arm grips the upstream loop section when the loop is cut and moves the upstream loop section generally parallel to an incoming section of wire from a baling wire supply roll to create a supply wire overlap. A second gripper arm grips the downstream loop section and moves it adjacent to the bale and generally parallel to wire from a baling wire supply roll to form a bale wire overlap.Type: GrantFiled: January 5, 1998Date of Patent: February 16, 1999Assignee: L & P Property Management CompanyInventor: John Wiedel

Patent number: 5743309Abstract: A joining tool for automatically joining or intertwining two or more items, preferably reinforcement rods (23). The joining tool advances a joining wire (6) in a not predetermined length through a track (5) in a ring-shaped head (2). The advancing movement of the joining wire (6) stops when the wire has completed the turn and the wire is then held at its free end by a holding pin (10) whereupon it is pulled back until it is tight around the reinforcement rods (23). Upon tightening the joining wire (6) is held by another holding pin (12) whereupon two cutting sleeves (14 and 15) cut the joining wire (6). After cutting, a turning head (7) is rotated until the desired joining strength is obtained. The desired joining strength is determined by a U-shaped brace (19). When the desired joining strength has been obtained, the joining wire is released by the holding pins (10 and 12).Type: GrantFiled: October 1, 1996Date of Patent: April 28, 1998Inventor: Rolf James Slater Christensen

Patent number: 5682927Abstract: A tying method and apparatus which is carried to easily automatically band bar-like articles such as reinforcements or pipes and various other articles by a linear tying material. The apparatus comprises tying material feed means (6), tying material bending means (8), encompassing and guiding means (9), tying material cutting means (7) and twisting means (11), wherein a starting point is formed in a way such that a part of a continuous linear tying material w delivered from the tying material feed means comes into engagement with the tying material bending means so that the tying material is bonded into a U-shape. In that state, the tying material is delivered from one side whereby the tying material is guided around an article to be tied by the encompassing and guiding means (9) while being bended into a substantially U-shape. The tying material is cut into a predetermined length, and both ends of the tying material are twisted together by a hook (25) of the twisting means (11).Type: GrantFiled: February 9, 1996Date of Patent: November 4, 1997Assignee: Bentac Co., Ltd.Inventors: Seiichi Takahashi, Youzou Kaneko, Tsutomu Saito
