Abstract: A spool endform assembly includes an endform with a central collar that are configured to rotate about a rotational axis. The spool endform assembly further includes a mount sub-assembly configured to be mounted in a fixed orientation on a mounting structure (such as movable arm). The spool endform assembly is further configured to permit misalignment of the fixed orientation of the mount sub-assembly relative to the rotational axis of the endform and central collar. In embodiments, controlled movement of the mounting structure can be used to connect the spool endform assembly to a rotatable mandrel of a wire winding spool and disconnect the spool endform assembly from the rotatable mandrel. By permitting misalignment of the fixed orientation of the mount sub-assembly relative to the rotational axis of the endform and central collar, the spool endform assembly makes it easier to connect the spool endform assembly to the rotatable mandrel and to disconnect the spool endform assembly from the rotatable mandrel.

Abstract: 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.

Abstract: 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.

Abstract: An apparatus for winding filamentary material includes a mandrel rotatable about a spindle axis of rotation and a traverse reciprocating at a distance with respect to the spindle axis to wind the filamentary material in a figure-eight coil configuration with a payout hole extending radially from the inner to the outer wind of the coil. The apparatus includes a measurement device for measuring the diameter of the coil as it is being wound around the mandrel, and a controller for controlling the reciprocating movement of the traverse with respect to the rotation of the mandrel based on the measured diameter of the coil. The measurement device may include a first sensor configured to measure a length of filamentary material wound about the mandrel and a second sensor configured to measure an angular displacement of said mandrel during the winding of the length of filamentary material about said mandrel.

Abstract: A locking ring is described that permits removal of filamentary material housed in a walled container through a payout tube defining a payout tube axis and through which a first end of the filamentary material extends. The ring includes an annular flange around a ring axis and a body having a tubular wall extending from an inner edge of the annular flange to a distal edge of the ring. The tubular wall is coaxial with the ring axis, and has a plurality of teeth circumferentially spaced around the tubular wall and extend from the tubular wall radially outwardly and toward the annular flange. Each tooth resiliently deflects radially inwardly in response to interference between the tooth and an inner wall of the payout tube. The curved edges form a thread permitting the ring to advance axially into and secure with the payout tube.

Abstract: A mandrel for the winding of wire includes a central element and segments radially extending about and respectively coupled to the central element by rotatable arms that permit the segments to assume a collapsed position and an extended position Inner surfaces of the segments define slots in which ends of the arms extend. One segment also defines a radially extending groove on an outer surface of that segment which intersects with the slot of that segment to define an opening through the segment. A resilient pad is fixed in the slot of that segment and has a face located at the opening and adjacent a surface of an arm coupling that segment to the central element. A wire is threaded into the opening and held in place when the arms are rotated to cause the segments to assume the extended position. Methods using the mandrel are disclosed.
