摘要： A reinforcing bar binding machine includes a magazine in which two wires are housed in a drawable manner; a curl guide unit that winds the juxtaposed wires around the reinforcing bars and a wire feeding unit that winds the wires around the reinforcing bars with the curl guide unit in an operation of juxtaposing and feeding the wires so that the wires are wound around the reinforcing bars. In addition, the binding machine includes a binding unit that twists crossing portions of one end side and the other end side of each of the wires wound around the reinforcing bars. The binding unit further includes a bending portion that bends the one end side and the other end side of each of the wires, which are wound around the reinforcing bars, toward the reinforcing bars.

摘要： A binding machine includes a wire feeding unit, a curl forming unit, a cutting unit, and a binding unit. The wire feeding unit includes a feeding member having a part that is in contact with the wire and configured to feed the wire with being displaced along a feeding direction of the wire. An amount of contact between the feeding member and the wire is switched in accordance with the feeding direction of the wire. As compared to the amount of contact in an operation of feeding the wire in one direction, the amount of contact in an operation of feeding the wire in other direction, which is opposite to the one direction, is made larger.

摘要： A reinforcing bar binding machine reduces restrictions on a moving direction in pulling out from a reinforcing bar bound with a wire. The reinforcing bar binding machine (1A) includes a curl guide unit (5A) that winds a wire (W) around a reinforcing bar (S), a wire feeding unit (3A) that feeds the wire (W), and a binding unit. A first guide unit (50) curls the wire (W) fed by the feeding unit (3A) and a second guide unit (51) guides the wire (W) fed from the first guide unit (50) to the binding unit (7A). The second guide unit (51) includes a fixed guide unit (54) that restricts a position in a radial direction of the wire (W) wound around the reinforcing bar (S) and a movable guide unit (55) that restricts a position in an axial direction of the wire (W).

摘要： A binding machine includes a wire feeding unit configured to feed a wire to be wound on an object to be bound, a cutting unit configured to cut the wire wound on the object to be bound, and a binding unit configured to twist the wire wound on the object to be bound. The cutting unit includes a pair of blade parts configured to interpose the wire therebetween and cut the wire. One or both of the pair of blade parts include a delay part which is configured to delay cutting a part of the wire as compared to a remaining part of the wire.

摘要： The wire fed or pulled back from the reel by the feeding unit can be properly restricted. The invention relates to a binding machine (2) having a feeding unit (16) for feeding out a wire (3) from a reel (12) provided in a housing unit (11). With respect to the entering route (81) of the wire (3) when the wire (3) drawn out from the reel (12) by the feeding unit (16) is guided to the feeding unit (83), the first restriction unit (83) that restricts the drawing portion (3a) of the wire (3) disposed between the reel (12) and the feeding unit (16) from being deviating from the entering route (81) is provided inside the housing unit (11).
