This invention relates to a tension buffer system for multi-wirepay-off system. The tension buffer system comprises guiding pulleys (4, 4a, 4b) adapted to guide wires (6, 6a, 6b) being paid off, and reversing pulleys (8). Each reversing pulley (8) is adapted to guide a wire (6, 6a, 6b) from the guiding pulley (4, 4a, 4b) and back to the guiding pulley (4, 4a, 4b), two reversing pulleys (8) are rotatably mounted on a first support (10), the first support (10) is pivoted around first support axis (12) lying between the two reversing pulleys (8) so that pivoting brings one of the two reversing pulleys (8) closer to the guiding pulley (4, 4a, 4b) while the other of the two reversing pulleys (8) more remote from said guiding pulley (4, 4a, 4b). This invention provides a mechanical device to balance the tension difference between multiple wires in the pay-off system to produce a steel cord with constant tension and satisfactory quality.

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.

Provided are a filament winding method and a filament winding apparatus, in which, when a new bobbin is mounted on a bobbin rotation driving device, the control device is programmed to rotate the bobbin and oscillate a dancer while maintaining a state where a distal end of filament unwound through the dancer is fixed further beyond the dancer and the filament is stretched. The control device is programmed to obtain a bobbin diameter of the bobbin mounted on the bobbin rotation driving device based on a length of the dancer, an oscillation angle of the dancer, and a rotation angle of the bobbin.

A yarn feed assembly for directing yarn from a wound yarn source to a yarn feed tube having a frame member positioned adjacent to the wound yarn source and defining at least one elongate interior chamber. The yarn feed assembly has a weighted member slideably received in the elongate interior chamber such that, upon pulling one yarn off of the wound yarn source, through a bore of the weighted member and into the yarn feed tube, the weighted member is axially movable along a longitudinal axis of the frame member such that the bore of the weighted member is axially movable about and between a bottom end and a top end of the elongate slot in response to tension applied to the yarn as a result of yarn hang ups on the wound yarn source.
