A twisted wire manufacturing method for manufacturing a twisted wire, includes hanging U-turn portions of the at least two wires on a wire hanging member, checking one end portions and the other end portions of the at least two wires, pulling up the at least two wires in a state that the U-turn portions are hung on the wire hanging member, twisting the at least two wires together after the wire pull-up step is conducted, and transferring a twist-completed wire produced by the wire twisting step to a twisted wire temporary placement hook which is disposed above the wire hanging member.

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.

Method and means of manufacturing ties, fasteners and rods (15) having a plurality of longitudinal threads by forcing a coil of roll-profiled feed-wire made of steel (11) through a twisting-die made of plastic (1). Also described is: a twisting-die made of plastic (1) that is suitable for twisting profiled feed-wire (11) made of steel; a method of forming a plastic twisting die (1) using an driven tap (31) in the form of a twisted rod (15); and a helically-shaped member (15) having lead measurements (X) along the length of the helical thread that vary less than pitch measurements (Y) along the lengths of the helical threads.

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).
