APPARATUS AND METHODS FOR WIRE-TYING BUNDLES OF OBJECTS

摘要

The object of the invention herein being a feed and tension mechanism (600) comprising a feed and tension wheel (645), an accumulator wheel (641), a primary nip mechanism (661) for frictionally engaging the wire at the contac t region between the primary nip (661) and the feed and tension wheel (645), a drive system having two independently operable motors (673, 675), and wire guiding devices (601, 605, 607, 609, 611, 613) for directing and routing the wire through the feed and tension mechanism (600). The present invention may further comprise a supplementary nip mechanism (643) to facilitate the threading of the wire into the mechanism, a wire stripping mechanism (800) f or extracting any waste wire from the mechanism, and a series of wire sensing devices in communication with a control system to sequence and control the operational cycles of the system. The feed and tension mechanism further includes a frame (671) that structurally supports the major assemblies and attaches to the wire-tying machine (100).
