A device for imparting a torsional force onto a wire has a base and a support mounted so as to be rotatable with respect to the base around an axis of rotation. The axis of rotation coincides with a wire path extending through the base and the support. Further, a wire clutching device is mounted on the support and adapted to engage at a wire guided along the wire path, and a rotation mechanism is provided which is adapted for rotating the support with respect to the base.

An item and an associated method utilizing an elongated core defining an outer surface having a series of axially-disposed regions about which windable materials can be wound involves anchoring locations at which the terminal ends of windable materials are anchorable. The series of regions are arranged along the core of the item in a sequential fashion with a first region being disposed adjacent a first end of the core, and the anchoring location of each subsequent region in the series of regions subsequent to the first region is circumferentially spaced about the outer surface of the core from the anchoring location of the region which immediately precedes the subsequent region by a predetermined distance and in a circumferential direction therealong which is opposite the direction in which the item is rotated during a material unwinding process.

A lead wire storage mechanism stores most of a lead wire such that the lead wire can be taken out from a tip end portion. A tension adjusting mechanism including a dancer roller and two lifting and lowering guide rollers is formed with a partial space that is to be a part of a hand travel space at a time of a preparation state. A lead wire guide mechanism including an opening and closing lead guide is formed with a partial space that is to be a part of the hand travel space at the time of the preparation state. A lead wire grasping and moving mechanism can execute a grasping operation for grasping a tip end portion of the lead wire with a grasping part, and a grasping part moving operation for moving the grasping part through the hand travel space.

The wire feeding device that feeds welding wire W from the wire source to the welding torch is disposed between the wire source and the welding torch and is configured to temporarily accommodate the welding wire W fed from the wire source and to feed the accommodated welding wire W to the welding torch. In the case where feeding of welding wire W is abnormally stopped, if the acceptance unit accepts instructions for increasing or decreasing, the wire feeding device controls the speed of feeding welding wire W fed by the first feeding part or the second feeding part so that a difference is generated in the feeding speed of the first feeding part and the second feeding part and the accommodated amount of welding wire W is in a range from the lower limit of normal to an upper limit of normal.

One aspect is an ablation system with a wire feed configured to feed a wire and a wire take-up configured to take-up the wire. A wire handling system is configured to advance the wire and to stop the wire between the wire feed and the wire take-up in a controlled manner. A laser ablation processor is located between the wire feed and the wire take-up, the laser ablation processor having at least one laser configured to ablate the wire when the wire is stopped. A clamp system is located between wire feed and the wire take-up and configured to clamp onto the wire when the wire is stopped.

A tension information acquisition device acquires tension of a wire electrode and is provided with: a back tension adjustment unit that makes the magnitude of back tension of the wire electrode zero; and an acquisition unit that acquires tension information indicating the tension on the basis of a disturbance estimate value or output torque of a feed motor when the magnitude of the back tension is zero.

In a method of manufacturing a rubber coated twisted wire cord, when an outer circumferential surface of a twisted wire cord that is moving from an unreeling unit to a winding unit is coated with unvulcanized rubber extruded by a rubber extruder, by a coating unit disposed between the unreeling unit and a winding unit, in a state of additional tension being imparted on the moving twisted wire cord by a tension imparting unit disposed at a nearby position on an upstream side from the coating unit in a moving direction of the twisted wire cord, the unvulcanized rubber coats the outer circumferential surface of the twisted wire cord in this state to continuously manufacture a rubber coated twisted wire cord.

A method for manufacturing a wire saw apparatus including a wire supply reel; a long roller; wire guides; a wire winding reel; and a tension arm controlled to move within a control angle of ±A (°) set in advance and configured to apply tension to the wire, the method including the steps of: measuring a surface roughness Rmax of the long roller; measuring an angle a (°) of the tension arm at which the tension arm swings outside a range of the control angle set in advance while the wire is extending from the wire supply reel; calculating R1×2×A÷(|a|+A)=R2, where R1 (μm) represents the measured surface roughness Rmax of the long roller; and adjusting the surface roughness Rmax of the long roller to the calculated numerical value R2 or less. The method for manufacturing a wire saw apparatus can prevent the tension arm from greatly swinging outside the control range.

A demountable wire carrier 100 is for supporting loops of wire W and comprises a lower end-stop 110, an upper end-stop 120 and a plurality of frame members 130 extending between the end-stops. The carrier is shown standing inside a cylindrical loop-forming container 140 into which the wire W has been fed in the direction of Arrow A, so that the wire forms loops around the inside of the container wall. The introduction of the wire takes place when, prior to assembly of the carrier, only the lower end-stop 110 is positioned inside the container, so that the loops of wire rest on the lower end-stop 110. After all the wire has been introduced into the container 140, the frame members are connected to the lower end-stop, and the upper end stop is then connected to the frame members to complete assembly of the carrier.

An apparatus for a drill powered wire puller is disclosed. The drill powered wire puller includes a capstan, a housing positioned including a gear mechanism disposed therein, and a trigger assembly coupled to a trigger of a handheld power drill, wherein actuation of the trigger assembly causes depression of the trigger thereby activating the handheld power drill. The drill powered wire puller further includes a cradle plate including a notch positioned at a proximal end of the cradle plate, the notch being sized and shaped to receive the handheld power drill. The drill powered wire puller further includes a foot pedal system including a foot pedal, a base, a spring, wherein when the foot pedal receives pressure, tension is created on the throttle causing actuation of the trigger assembly and activation of the handheld power drill.
