A wire tie assembly and method of tying a wire using the wire tie assembly is provided. Embodiments of the wire tie assembly comprise a gear-train having a main-drive gear continuously driven by a motor, an idler gear having a first and second dwell portions, the idler gear being configured to mesh with the main-drive gear during a portion of the wire-tying cycle and to dwell relative to the main-drive gear during a portion of the wire-tying cycle, and a twister pinion gear having a wire receiving channel and configured to be in mesh with the idler gear during a portion of the wire tying cycle and to dwell relative to the idler gear during a portion of the wire tying cycle. Some embodiments include cam pins coupled to the idler gear and cam followers that engage the cam pins to actuate secondary functions of the wire tying cycle.

A binding machine includes a wire feeding unit configured to feed two wires to be wound on an object to be bound, a wire guide configured to align the two wires in parallel, a binding unit having an engaging member in which the wires are to be engaged, and the binding unit configured to twist the wires which are wound on the object to be bound and which are engaged in the engaging member, a curl guide configured to curl the wires being fed by the wire feeding unit into a loop shape, an inductive guide configured to guide the wires curled by the curl guide toward the binding unit, and a parallel alignment regulation part configured to guide an alignment direction of the two wires to be engaged with the engaging member in a radial direction of the loop.

A binding machine includes a wire feeding unit configured to feed a wire to be wound on an object to be bound and a binding unit configured to twist the wire wound on the object to be bound. The wire feeding unit includes a pair of feeding members configured to sandwich the wire between the pair of feeding members and to feed the wire by a rotating operation, a wire feeding drive unit connected to one feeding member and configured to rotatively drive the one feeding member, and a load reducing part configured to reduce or remove a load, which is to be applied to the wire via the one feeding member, of the wire feeding drive unit.

A binding machine includes: a wire feeding unit configured to feed a wire; a curl forming unit configured to form a feeding path of the wire along which the wire fed in a first direction by the wire feeding unit is wound around an object; and a binding unit configured to twist the wire fed in first direction by the wire feeding unit and wound on the object. The wire feeding unit includes a pair of feeding members configured to sandwich the wire and to feed the wire by a rotating operation, and a feeding motor configured to drive the feeding members. The binding machine further includes a control unit configured to control the wire feeding unit. The control unit is configured to control the wire feeding unit to enable the wire sandwiched by the feeding members to be discharged from the feeding members.

A binding machine includes: an accommodation portion accommodating a reel around which a wire is wound; a wire feeding portion configured to feed the wire in a forward direction, winds the wire around a binding object, feeds the wire in a reverse direction, and wraps the wire around the binding object; and a torsion portion that twists the wire. The accommodation portion accommodates the reel such that the reel is offset in one direction along an axial direction of the reel with respect to the wire feeding portion. The binding machine further includes a restricting portion, in a wire passage between the reel and the wire feeding portion, which protrudes inward of the accommodation portion and has a restricting surface with which the wire bent in the other direction along the axial direction of the reel between the reel and the wire feeding portion comes in contact.

A binding machine includes a first main body, a second main body and a bridge part. The first main body houses a binding part which twists a wire and a driving part which drives the binding part. The second main body is provided with a handle part including an operation trigger. The bridge part connects the first main body and the second main body to each other.

A reinforcing bar binding machine (1A) includes a magazine (2A) in which a wire (W) is housed, a curl guide unit (5A) that winds the wire (W) around a reinforcing bar (S), a wire feeding unit (3A) that feeds the wire (W), and a binding unit (7A) that twists crossing portions between one end and the other end of the wire (W) wound around the reinforcing bar (S). The wire feeding unit (3A) is configured such that a second displacement member (36) for displacing a second feed gear (30R) is located behind a second feed gear (30L) and provided between the second feed gear (30L) and a handle portion (11A).

A rebar tying tool includes a reel housing, a guide, and an antenna. The reel housing houses a reel on which a tying wire is wound. The guide is located frontward from the reel housing to guide the wire drawn from the reel into a loop. The antenna is located inside the reel housing or at a member included in the reel housing.

A tying machine disclosed herein includes a feed mechanism. The feed mechanism includes a feed roller that feeds a tying string; a feed motor that rotates the feed roller; a cover disposed between the feed roller and the feed motor, and including a through hole; and a suppression member that suppresses movement of dust from a feed roller side to a feed motor side via the through hole. Another tying machine disclosed herein includes a reel on which a tying string is wound; a brake member that engages with the reel to brake the reel; and an actuator that drives the brake member. The brake member is interposed between the reel and the actuator. Yet another tying machine disclosed herein includes a housing; a reel on which a tying string is wound; a magnet that rotates integrally with the reel; and a magnetic sensor attached to the housing.

An apparatus for twist tying wire around intersecting rebar bars. The apparatus is configured to receive and discharge precut wire segments, form and wrap the wire around the rebar, and twist the wire securely around the rebar. The user merely positions the tool at the rebar intersection, release a wire segment into the work end of the tool, and with a single fluid motion move a slide mechanism up to bend the wire segment around the rebar and twist it about itself to tie the rebar together.
