The wire electric discharge machining device includes a wire bobbin configured to wind and hold a wire electrode, a wire delivery roller configured to draw the wire electrode from the wire bobbin and deliver the wire electrode continuously toward a work-piece, a brake motor configured to apply a load to the wire bobbin in a direction against the drawing of the wire electrode, rotation speed detector configured to detect a rotation speed of the wire bobbin, an emptiness determination device configured to determine that the wire bobbin reaches an empty state based on a rapid change in the rotation speed of the wire bobbin detected by the rotation speed detector, and a drive control part configured to stop the drive of the wire delivery roller when the emptiness determination device determines that the wire bobbin reaches the empty state.

A container includes an outer box, and a polygonal liner located within the outer box. The polygonal liner has a plurality of vertical walls. A continuous length of wire is located within the polygonal liner and forms a plurality of layers. Each of the layers is comprised of a series of wire loops arrayed polygonally along the vertical walls of the polygonal liner.

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.

The present invention discloses a bead wire wrapper device and a wrapper method. The bead wire wrapper device comprises a rack body; the rack body is provided with a winding unit, an H-shaped wheel assembly, a paper cutting mechanism, a paper guiding mechanism and a rubber applying mechanism; the winding unit comprises a first winding shaft and a second winding shaft; the H-shaped wheel assembly comprises an H-shaped wheel and a drive unit driving the H-shaped wheel to rotate; the paper cutting mechanism is configured to cut off film materials directly or indirectly fed by the winding unit; the paper guiding mechanism comprises a motion mechanism, the motion mechanism is provided with an adsorption assembly and a pressing assembly, the adsorption assembly is configured to adsorb the film materials through negative pressure and send the cut-off tail ends of the film materials to the H-shaped wheel under the action of the motion mechanism, and the pressing assembly is configured to move to the H-shaped wheel under the action of the motion mechanism and press the film materials; and the rubber applying mechanism is configured to paste rubber strips to the film materials on the H-shaped wheel.

In order to increase the operational safety of an unreeling apparatus and an unreeling method at high working speed, an unreeling apparatus for unreeling a ring of wire along a pull-off direction, having at least two reel crowns, which can each be brought into a pull-off position and into a preparation position and/or loading position by way of a displacement device, includes a safety apparatus having an overload safety device and having a safety guide track, which has a directional component that faces in the pull-off direction and acts independently of the other reel crown, at least for the reel crown situated in the pull-off position, wherein the overload safety device holds the reel crown situated in the pull-off position in the pull-off position and, in the event of an overload, releases the reel crown situated in the pull-off position into the safety guide track.

A wire tension control device including a bobbin and a magnetic moment generator is provided. The bobbin is configured to provide a wire. The magnetic moment generator includes a stator and a rotor relatively rotatable with respect to the stator. The rotor is connected to the bobbin. When the bobbin drives the rotor to rotate, the magnetic moment generator generates a tension on the wire.

A rotary body including a drum and a wire support member winds a wire by rotation. A spacer is provided on the rotary body and is displaceable to a first position and a second position in the rotary body. When the spacer is in the first position, the wire is wound on the rotary body not via the spacer, and hence the wire is wound with the first diameter. When the spacer is in the second position, position, the wire is wound on the rotary body via the spacer, and hence the wire is wound with a second diameter larger than the first diameter.

Apparatuses, systems, and/or methods for securing and unsecuring a wire feeder in an automatic welding system without using tools are disclosed. The welding system can include, for example, a robotic arm with a welding torch, an adaptor, and a wire feeder. The adaptor can include, for example, a quick-disconnect member located on the robotic arm. The wire feeder that can be removed from the adaptor after the quick-disconnect member has been actuated. The wire feeder can be installed and secured with tools by placing the wire feeder in the actuator and actuating the quick-disconnect member of the actuator.

A winding device capable of easily winding an electric wire and a method of manufacturing a spiral electric wire are provided. The electric wire delivered by the delivery device is guided by the guide device toward the center portion of the projecting portion. The projecting portion of the winding device has an inclined surface whose outer diameter increases toward the base portion from the tip end on its outer peripheral surface. As a result, the electric wire can be wound around the projecting portion by utilizing the force of the delivery device, and the electric wire can be easily wound up.
