An automated machine for forming winding structures without the use of a mandrel using a driven headstock and driven tailstock. The winding machine allows for selective orientation and selective layering of the filament as it is wound onto the pin rings. The winding structure can receive forms into a hollow center and the composite placed in a female mold. Alternatively the winding structure may be formed into a laminate which can be orientated and aligned on a form to achieve desired mechanical properties.

The present invention provides a metal strip coil that can suppress a shape failure at an end portion of the coil. A metal strip coil including a metal strip wound around a winding core, wherein the metal strip is wound from one end side toward the other end side of the winding core, turns back at the other end portion, is wound from the other end side toward the one end side of the winding core, turns back at the one end portion, and is repeatedly wound in such a manner, wherein in the turnback, the metal strip has a turnback portion at which the metal strip is wound in a direction perpendicular to the axial direction of the winding core, in a side view of the metal strip coil, the turnback portion is arcuate, and the turnback portions are formed in a multistage manner from the inner circumference toward the outer circumference, and a line connecting a midpoint of the arcuate arc with the center of the arc is formed so as to rotate stepwise in one direction, in an order of the arcuate turnback portions which are formed in a multistage manner from the inner circumference to the outer circumference.

A dispenser system containing a container and a single elongated element. The single elongated element is rotationally wound in a first direction into a hollow cylinder having a central axis. The hollow cylinder is located within the volume of the container and the single elongated element is unwound from the hollow cylinder from one of the annular bases. The single elongated element has a twist in a second direction opposite to the first direction such that when the single elongated element is unwound it has essentially no twist.

A winding system containing a let off stand, a winding coordinator, and a wind-up stand. The left off stand contains a tape holder and a generally planar base which rotates in a first direction. The winding coordinator contains a generally planar section having an opening for an elongated element and rotates in a second direction opposite to the first direction.

A system for winding wire includes a wire take-up unit and a wire cutter/grabber unit. The take-up unit includes rotatable first and second mandrel portions, and a wire directing traverse arranged to feed wire and alternately form coils on the first and second mandrel portions. The cutter/grabber unit is configured to cut the wire at a cut position between the traverse and a coil formed on the first mandrel portion and to grab a free end of the cut wire and move along a predefined cutter/grabber pathway to a hand-off position where the wire is transferred to the second mandrel portion. As the cutter/grabber is moved along the pathway from the cut to the hand-off position, a length of wire between the traverse and the free end of the wire does not decrease, and that length of wire is longer at the hand-off position than at the cut position.

A dispensing cap for a dispensing system may be adapted for dispensing a roll of longitudinally extending material arranged in a center-pull configuration. The dispensing cap may include a dispensing orifice. A first rim having an inner edge may define a wide end of the dispensing orifice. A second rim having an outer edge may define a narrow end of the dispensing orifice. One or more sidewalls may extend between the inner edge of the first rim and the outer edge of the second rim and define the dispensing orifice between the wide end and the narrow end. The dispensing cap may further include a dispensing slot that defines an opening through the second rim.

Systems and methods for winding wire are disclosed. A system includes a wire take-up unit and a wire tensioning unit. The take-up unit includes a rotating mandrel and a wire directing device, the wire directing device arranged to cause the wire to be wound in a figure-eight configuration on the rotating mandrel to form a coil having many layers of wire. The wire tensioning unit applies tension to said wire as it is wound, and applies a first amount of tension to a predetermined amount of wire constituting at least a first two layers of the coil, and a second amount of tension to the wire beyond the predetermined amount. In one embodiment, the wire tensioning unit includes digital self-relieving air regulator pneumatically coupled to and controlling a pressure in said pressurized chamber of a pre-lubricating cylinder that is coupled to the wire being wound.
