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.

A system is configured to automatically band a product with a portion of twist tie material and includes a tying machine which includes a twisting barrel, a tie payout assembly, a tie feeding assembly, a main drive belt, and a tying ring. The tie payout assembly includes a spool shaft configured for mounting a tie spool of the twist tie material. The tie feeding assembly is configured to receive the twist tie material from the tie payout assembly and includes a feedroller, a nip roller, a forward feedroll clutch, a reverse feedroll clutch, and a feedroll belt. The nip roller is configured to contact the feedroller with the twist tie material therebetween. The forward feedroll clutch is engageable with a forward feedroll pulley that surrounds a forward feedroll shaft. The reverse feedroll clutch is engageable with a reverse feedroll pulley that surrounds a reverse feedroll shaft.

It provides a reinforcing bar binding machine capable of surely wrapping and binding a wire to a binding object. The reinforcing bar binding machine (1A) includes a magazine (2A) in which two wires (W) are housed so as to be drawable, a curl guide unit (5A) which winds the arranged wires (W) around the reinforcing bar (S), by the operation of feeding the parallel wires (W) at the curl guide unit (5A) to wind around the reinforcing bar (S), a wire feeding unit (3A) which to wrap around the reinforcing bar (S) with the wires (W) wound around the reinforcing bar (S), and a binding unit (7A) which twists a intersecting portion between one end side and the other end side of the wire (W) wound around the reinforcing bar (S).

A binding machine includes: a wire feeder; a curl forming unit forming a wire feeding path for winding a wire fed in a first direction by the wire feeder; a binding unit configured to twist a wire wound around the objects to be bound; and a controller configured to control the wire feeder and the binding unit. The wire feeder includes a pair of feed members configured to clamp a wire and feed a wire by a rotation operation, and a feed motor configured to rotate in a first rotation direction to drive the feed members to feed a wire in the first direction, and the controller changes a state into a first state and a second state to feed a wire in the first direction, when a wire is inserted into a position where a wire is feedable in the first direction by the pair of feed members.

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.

A reinforcing bar bending machine detachably mounts a wire reel thereto, feeds a wire from the mounted wire reel to a guide part provided at a tip portion of a binding machine main body, curls the wire at the guide part, feeds the wire around reinforcing bars to wind around reinforcing bars, cuts the wire with a wire cutting mechanism, and twists the wound wire to bind the reinforcing bars. The wire cutting mechanism is a cutter including a moveable blade configured to slide or swing to a fixed blade or to rotate inside the fixed blade and to cut the wire. The guide part is provided with a holding device to hold a cut end portion-side of the wire cut and separated in conjunction with a cutting operation of the moveable blade. The holding device bends and holds the cut end portion-side of the cut and separated wire.
