Abstract
Systems and methods for threading and feeding a length of wire into a wire-tying track, for withdrawing at least some of the wire from the wire-tying track to tension the wire around one or more objects, and for extracting waste wire from the system. The object of the invention herein being a feed and tension mechanism comprising a feed and tension wheel, an accumulator disk, a primary nip mechanism for frictionally engaging the wire at the contact region between the primary nip and the feed and tension wheel, a drive system having two independently operable motors, and wire guiding devices for directing and routing the wire through the feed and tension mechanism. The present invention may further comprise a supplementary nip mechanism to facilitate the threading of the wire into the mechanism, a wire stripping mechanism for 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 that structurally supports the major assemblies and attaches to the wire-tying machine.
