Abstract
Abstract The distance between turns of wire being wound on a spool is determined and controlled by generating a signal proportional to the traverse speed, generating a signal proportional to the spool speed, dividing one by the other, and displaying the output signal in units traversed per spool revolution. The traverse speed is then adjusted until the traverse rate is slightly greater than the wire width.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
73 words
In an apparatus for winding a wire onto a spool, said apparatus having means for controlling the speed at which said wire traverses relative to said spool speed, a method of setting and thereafter maintaining as set the distance traversed per spool revolution regardless of changes in spool speed, comprising: 1. generating a first signal proportional to said traverse speed; 2. generating a second signal proportional to the speed that said spool rotates;
Claim 2
Dependent Claim
73 words
In an apparatus for winding a wire onto a spool, said apparatus having means for controlling the speed at which said wire traverses relative to said spool speed, a method of setting and thereafter maintaining as set the distance traversed per spool revolution regardless of changes in spool speed, comprising: 1. generating a first signal proportional to said traverse speed; 2. generating a second signal proportional to the speed that said spool rotates;
Claim 3
Dependent Claim
50 words
dividing one signal by the other to produce an output signal; 4. displaying said output signal in units of distance traversed per spool revolution; 5. adjusting said traverse speed until the desired distance traversed per spool revolution is displayed; and 6. maintaining the ratio of traverse speed to spool speed.
Claim 4
Dependent Claim
50 words
dividing one signal by the other to produce an output signal; 4. displaying said output signal in units of distance traversed per spool revolution; 5. adjusting said traverse speed until the desired distance traversed per spool revolution is displayed; and 6. maintaining the ratio of traverse speed to spool speed.
Claim 5
Dependent Claim
15 words
A method according to claim 1 wherein said spool traverses and said wire is fixed.
Claim 6
Dependent Claim
44 words
A method according to claim 1 wherein said apparatus is first operated without wire and said traverse speed is set according to said display so that the distance traversed per spool revolution is slightly greater than the width of the wire to be wound.
Claim 7
Dependent Claim
14 words
A method according to claim 1 wherein said first and second signals are voltages.
Claim 8
Dependent Claim
11 words
A method according to claim 1 wherein said wire is rectangular.
