Provided are a systems and methods for continuously providing a metal wire to a welding torch for manufacturing objects by solid freeform fabrication to provide continuous deposition of metal to the freeform object, especially objects made with titanium or titanium alloy wire.

A reinforcing bar binding machine capable of reliably performing a wire gripping operation includes a first movable gripping member that is displaced in a direction to contact with and separate from one side of a fixed gripping member and a second movable gripping member that is displaced in a direction to contact with and separate from the other side of the fixed gripping member. A bending portion brings the first movable gripping member and the second movable gripping member into and out of contact with the fixed gripping member. The fixed gripping member includes a shaft that rotatably supports the first movable gripping member and the second movable gripping member. Further, the bending portion includes an opening and closing pin that pushes an opening and closing guide hole provided in the first movable gripping member, and an opening and closing guide hole provided in the second movable gripping member.

Disclosed is a device for repairing deep-water cage nets. The device includes an open-frame underwater robot and a repairing mechanism of deep-water cage nets, where the repairing mechanism of deep-water cage nets includes a hole penetrating mechanism, a wire feeding mechanism, a rotary knotting mechanism, a steel wire cutting mechanism and steel wire clamping mechanisms. The hole penetrating mechanism comprises mechanical claws and a control box for controlling the mechanical claws. The wire feeding mechanism and the steel wire cutting mechanism are both fixedly arranged in the control box, and the steel wire clamping mechanisms and the rotary knotting mechanism are both arranged between two mechanical claws. The open-frame underwater robot is detachably connected with the repairing mechanism of deep-water cage nets through a connecting shaft.

The present invention relates to an apparatus for manufacturing reinforcement meshes and spinning stations therefor. Reinforcement rods to be joined with the spinning wires are supplied by advancing means from the rear end of the apparatus, and a special mechanism prevents that the wire breaks during its encounter with the reinforcement rod.

A feed mechanism for pocketed spring strands is provided with at least one index wheel having a plurality of blades. The feed mechanism is provided with a motor. The at least one index wheel includes a first support member which is rotatable about a first rotation axis and carries a first support element which supports a shaft element of the blade to be tiltable about a tilt axis extending in parallel to the first rotation axis. The at least one index wheel includes a second support member which is rotatable about a second rotation axis which extends in parallel to the first rotation axis and carries a second support element which is slidable along the shaft element of the blade and supports the shaft element to be tiltable about the tilt axis.

A straightening apparatus for straightening cables includes a first roller group having several rollers and a second roller group having several rollers opposite the first roller group. The cable alternates in a transport direction between the rollers of the first roller group and the rollers of the second roller group. The straightening apparatus further includes an infeed device with which the first roller group can be displaced in a closing direction against the second roller group. In order to secure the position of the first roller group displaced in the closing direction by the infeed device, the straightening apparatus includes a backstop which blocks a backward movement of the first roller group against the closing direction. The backstop has a clamping roller which is received in a wedge gap.

A wire forming apparatus 1 comprises a rotary table 22 that is rotatably supported by a table body 21, a slide tool unit 100A that is attached to the rotary table 22 and supports a slide tool T1 capable of sliding toward a wire guide, and a tool slide mechanism 60 that is supported by the table body 21 and transmits a driving force for sliding the slide tool T1 to the slide tool unit 100A. The tool slide mechanism 60 has a single motive power transmission member 61 that is rotatably supported by the table body 21, and a driving force generated by a rotation of the motive power transmission member 61 is transmitted, in common, to a plurality of slide tools T1 attached to the rotary table 22.

A binding machine includes a wire feeding unit, a binding unit, a curl guide and an inductive guide. The inductive guide has a converging passage through which the wire fed by the wire feeding unit and curled by the curl guide passes, and a cross-sectional area of the converging passage decreases along an entry direction of the wire from an opening end portion that the wire enters. The inductive guide has an entry angle regulation part configured to change an entry angle of the wire entering the converging passage, and the inductive guide is provided on an inner side with respect to a virtual line interconnecting the opening end portion and a narrowest part of the converging passage at which the cross-sectional area is the narrowest.
