Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
162 words
In a wire winding apparatus including means for supporting a flanged spool and winding wire thereon, a wire guide arranged to traverse the wire back and forth lengthwise of the spool in use, a first end sensor associated with the flange at one end of said spool and a second end sensor associated with the flange at the other end of said spool, each of said end sensors being operative to automatically reverse the direction of the operation of the guide at the end of each traverse, the improvement which comprises means for automatically moving each end sensor after each actuation thereof away from the other end sensor by a first distance, means for detecting an accumulation of wire adjacent each flange of the spool, and means for automatically moving the end sensor associated with each of said flanges upon an accumulation being detected adjacent thereto toward the other end sensor by a second distance which is greater than said first distance.
Claim 2
Dependent Claim
162 words
In a wire winding apparatus including means for supporting a flanged spool and winding wire thereon, a wire guide arranged to traverse the wire back and forth lengthwise of the spool in use, a first end sensor associated with the flange at one end of said spool and a second end sensor associated with the flange at the other end of said spool, each of said end sensors being operative to automatically reverse the direction of the operation of the guide at the end of each traverse, the improvement which comprises means for automatically moving each end sensor after each actuation thereof away from the other end sensor by a first distance, means for detecting an accumulation of wire adjacent each flange of the spool, and means for automatically moving the end sensor associated with each of said flanges upon an accumulation being detected adjacent thereto toward the other end sensor by a second distance which is greater than said first distance.
Claim 3
Dependent Claim
21 words
Apparatus as claimed in claim 1, wherein said second distance is from 3 to 20 times greater than said first distance.
Claim 4
Dependent Claim
21 words
Apparatus as claimed in claim 2, wherein said second distance is from 5 to 10 times greater than said first distance.
Claim 5
Dependent Claim
51 words
Apparatus as claimed in claim 1, wherein the means for moving the end sensors includes a pair of servo motors and means for feeding pulses of varied length to actuate said servo motors, the distances moved by the end sensors being controllable by feeding pulses of varied length to said servo-motors.
Claim 6
Dependent Claim
50 words
Apparatus as claimed in claim 1, wherein the means for moving each end sensor said first distance is adapted to commence the said movement of one end sensor away from the other end sensor shortly before the reversal of direction of the said guide by the said other end sensor.
Claim 7
Dependent Claim
26 words
An apparatus as claimed in claim 1, wherein said means for detecting an accumulation comprises a dancer pulley attached to an arm connected to a potentiometer.
