Abstract:
An improvement in a wire winding apparatus of the type which includes a means for supporting and winding a flanged spool, a wire guide arranged to traverse the wire back and forth lengthwise of the spool in use and two end sensors which are operative to automatically reverse the direction of the operation of the guide at the end of each traverse, which improvement comprises (1) means for automatically moving each end sensor away from the other end sensor by a first predetermined distance after every actuation of the first mentioned end sensor, (2) means for detecting an accumulation of the wire adjacent either end of the spool and (3) means for automatically moving the end of the sensor associated with the flange toward the other end sensor by a second predetermined distance which is greater than the aforesaid first distance when such an accumulation is detected.
Abstract:
A method for laying elongated winding material, such as for example wire, insulated or non-insulated strands, glass fibers, and the like, in which the strand-type material is wound in layers onto rotationally symmetrically shaped winding spools, the winding material being guided to a winding spool via a deflecting roller for the laying, and for the distribution on the winding spool the deflecting roller is moved essentially parallel to the axial direction, a sensor unit acquiring the position of the spool flange as well as the winding diameter of the winding material, and control signals for the movement of the deflecting roller being derived from the measurement values of the sensor unit.
Abstract:
A laser beam (12) scans a filament (8) being wound onto a bobbin (42) sensing the winding angle of attack .beta. and on determining a variance of the angle from a predetermined desired angle generating a signal in a filament position monitor and control (38) for energizing a bobbin carriage drive (40) to correct the winding angle .beta.. Additionally, the laser beam (12) can scan filament (18) before it becomes the last winding on the bobbin (42) and on a climb-back or gap occurring the filament position monitor and control (38) reverses the spindle drive (41) to remove the climb-back or gap and then reassumes normal carriage drive (40) and spindle drive (41).
Abstract:
The invention relates to a method for detecting a traverse winding defect when winding a link (L) on a spool (1) rotatably driven about a longitudinal axis (X), the link (L) being alternately translationally guided relative to the spool (1) by a guide pulley (2) along said longitudinal axis (X) between two reversal positions, comprising:
measuring the position of the guide pulley (2) relative to the spool (1) along the longitudinal axis (X) over time, measuring the position (P2) of a regulation device for regulating the advance speed of the link on the guide pulley over time, from said measurements, determining a deviation between the position (P3) of the regulation device and a reference position (P3r) at each reversal position (Pi1,Pi2), and from said deviation, detecting the formation of a hollow or bump in the winding.
Abstract:
A method for implementing a correct winding of a wire on a spool. The method is characterized in that it comprises a step for calculating the angular speed of a motor displacing a wire dispensing device according to the wire winding pitch and according to the pulling error, detected in relation to a given pre-set set-point and to a tolerance value, in order to determine the presence of a possible “valley error”, or of a possible “peak error”. Furthermore, if during the spool winding a “valley error” or a “peak error” is detected, the control device decides whether to slow down or to increase the speed of the wire dispensing device with the aim of filling the valley or of skipping the peak.

Abstract:
A system for winding optical fiber onto a spool includes a spindle assembly for receiving the spool and rotating it around its longitudinal axis. A fiber source for providing a continuous supply of fiber to the spool is positioned relative to the spindle assembly such that rotation of the spool by the spindle assembly causes fiber to be wound onto the spool around its longitudinal axis. A tension sensing device senses and provides feedback related to the amount of tension in the fiber. A traverse assembly causes the fiber to wind onto the spool back and forth between a front spool flange and a rear spool flange, the traverse assembly including a front turnaround position at the front spool flange and a rear turnaround position at the rear spool flange. A controller receives the fiber tension feedback and uses the feedback to determine what adjustment, if any, is to be made to the front and rear turnaround positions.
Abstract:
In apparatus for winding a filament (12) onto a bobbin (16), a free arm follower (32, 64) with guide pulleys (46, 48, 76, 78) is provided for both the bobbin (16) and filament supply spool (14). The free arm followers swing in respective arcs parallel to the longitudinal axes of the supply spool (14) and bobbin (16) to produce consistent and uniform filament winding. A quadrature sensor (90) determines the number of actual windings laid down in each layer which are compared (94) with predetermined winding number and if the numbers do not coincide, a stop for flaw circuit (102) stops the spindle motors (28, 82) to enable winding flaw correction. A layer counter (104) energizes a lead angle driver (106) to provide correct winding lead on changing winding direction with each new layer.
Abstract:
A single-twist wire stranding or bunching machine having a reciprocating flyer traversing the length of a take-up reel and rotating coaxially with respect thereto, such take-up reel being mounted within pivoting means to facilitate easy removal of the reel after it is fully wound with wire. The invented machine comprises electro-mechanical means for automatically controlling the uniformity of the lay length of the twisted wire by correcting for changes in the velocity of the wire being fed into the machine due to wire build-up on the reel or to reversals of the traversing flyer. Additional control means are also disclosed for automatically controlling the points at which the flyer, in its reciprocating motion, reverses direction, thereby minimizing wire accumulations or recesses at the end flanges of the reel.
Abstract:
A spooler arranged for leading wire to a rotating spool through a wire tension controller and winding it onto the spool while distributing it in alternating directions along the spool between flanges thereof has means for varying the length of the distribution in either direction, arranged to be so controlled by means responsive to changes in the length of the wire in the wire tension controller in a period adjacent the moment of change to the other distribution direction as at least to reduce wound wire profile deficits or excesses adjacent the spool flanges.
