A manufacturing method for a coil includes: a step of winding a wire (conductive wire) in multiple layers and multiple rows and forming a coil having a trapezoidal cross-sectional shape; a step of arranging the coil in a molding space surrounded by a plurality of split dies; and a step of moving the slit die in a direction of narrowing the molding space to mold the cross-sectional shape of the coil. In the step of molding the cross-sectional shape, at least one of the plurality of split dies is moved to mold the cross-sectional shape into a fan shape by surfaces formed in the split dies.

A lattice structure, in particular a steel lattice structure, includes at least one longitudinal element and includes at least one edge element which runs perpendicularly or obliquely with respect to the longitudinal element, is embodied as a single wire, rod, wire strand, tube or profile and forms in particular at least a portion of a lattice edge, wherein the longitudinal element is wound multiple times around the edge element for its fastening to the edge element in a fastening region of the edge element.

A pair of jaws for a twist tying machine enables a user to tie products with a small outer diameter. The pair of jaws includes a fixed jaw that has a generally cylindrical housing attached to the twist tying machine and extending to a flat distal edge. A fixed jaw channel is formed within the fixed jaw and configured to accommodate a product tie from the twist tying machine. A movable jaw is rotatably attached to the twist tying machine and extends to a movable jaw distal end. A movable jaw channel is formed within the movable jaw and configured to accommodate the product tie from the fixed jaw channel. Closing the movable jaw against the fixed jaw enables the product tie to travel through the movable jaw around a product, and through the fixed jaw creating a tie around the product.

A reinforcing bar binding machine is provided with a cutting die having a wire through hole which penetrates through the die along a direction in which a wire is fed out, a blade portion adapted to move along an open plane of an opening at one end of the wire through hole to cut a terminating end portion of the wire which has passed through the wire through hole and an engagement portion adapted to be brought into engagement with a portion of the wire which lies in the vicinity of the terminating end portion thereof when the blade portion is rotated so as to bend to hold the portion lying in the vicinity of the terminating end portion.

A superconducting wire joining method joins superconducting wires each having a superconducting layer and a stabilizing layer that contacts with the superconducting layer to cover the superconducting layer. The superconducting wire joining method includes overlapping the superconducting wires such that the stabilizing layers of the superconducting wires face each other, and performing ultrasonic joining relative to overlapped portions of the superconducting wires. The overlapping of the superconducting wires and the performing of the ultrasonic joining are performed at room temperature.

A rebar tying robot disclosed herein may be configured to perform a rebar tying operation in which the rebar tying robot performs alternately and repeatedly an operation of moving over a primary rebar and a secondary rebar and an operation of tying the primary rebar and the plurality of secondary rebar together at points where the primary rebar and the plurality of secondary rebar intersect. The rebar tying robot may include a control unit, a longitudinal movement mechanism, a lateral movement mechanism, and a positional information detection mechanism configured to detect a current position of the rebar tying robot. The control unit may be configured to execute a return process in which the control unit control the rebar tying robot to move from the current position of the rebar tying robot to a specific position without performing the rebar tying operation.
