Abstract
Abstract A fabric winding process and apparatus for preparing a fabric pattern. A winding machine comprises a rotary drive mechanism for intermittent rotation of two card-holding chucks, and a thread-guide carriage which is translatable along a path adjacent a card held by the chucks parallel to the axis of rotation of the card. The drive mechanism and carriage are coupled such that when the winding card is not rotating, the carriage shifts a distance corresponding to a selected number of turns on the winding card such that a yarn of a selected color is wound about the card at all points on the card corresponding to the color in the desired fabric pattern. In this way, a desired pattern may be prepared without the necessity of threading or knotting several yarns together.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
113 words
In a process of preparing a fabric pattern by winding a plurality of yarns of various colors in a pattern about a rectangular card having front and rear sides, said pattern having at least one repetitive color with at least one different color interposed between repetitions, the improvement comprising the consecutive steps of winding a first yarn of a first selected color about said card at all points corresponding to said first color in said fabric pattern before a yarn of another color is wound about said card, and winding a second yarn of a second selected color about said card at all points corresponding to said second color in said fabric pattern.
Claim 2
Dependent Claim
113 words
In a process of preparing a fabric pattern by winding a plurality of yarns of various colors in a pattern about a rectangular card having front and rear sides, said pattern having at least one repetitive color with at least one different color interposed between repetitions, the improvement comprising the consecutive steps of winding a first yarn of a first selected color about said card at all points corresponding to said first color in said fabric pattern before a yarn of another color is wound about said card, and winding a second yarn of a second selected color about said card at all points corresponding to said second color in said fabric pattern.
Claim 3
Dependent Claim
53 words
The improvement of claim 1 including the step of winding each of said yarns about said card in a plurality of windings spaced on said card wherein each said winding is formed by winding said yarn into a plurality of turns being spaced relatively closely in comparison to the spacings between said windings.
Claim 4
Dependent Claim
54 words
The improvement of claim 2 wherein said windings are spaced from one another by extending said yarn from the last turn of a first winding to a point on said card spaced from said last turn a distance substantially greater than the spacing between said turns and winding the turns of an adjacent winding.
Claim 5
Dependent Claim
12 words
The improvement of claim 2 wherein said yarn comprises a single thread.
Claim 6
Dependent Claim
10 words
The improvement of claim 2 wherein said yarn is double-threaded.
Claim 7
Independent Claim
104 words
An apparatus for preparing a fabric pattern, comprising: rotary drive means, means for holding a rectangular card, means releasably coupling said card holding means to said drive means for controlled intermittent rotation of said card, a translatable thread-carrying carriage, means for guiding said carriage in a path parallel to the axis of rotation of said card, means for accurately guiding thread from said carriage to said card, means coupled to said drive means for controlling the speed of rotation thereof, and means selectively coupling said drive means to said carriage for transmittal of driving force to said carriage to effect translation of said carriage.
Claim 8
Independent Claim
104 words
An apparatus for preparing a fabric pattern, comprising: rotary drive means, means for holding a rectangular card, means releasably coupling said card holding means to said drive means for controlled intermittent rotation of said card, a translatable thread-carrying carriage, means for guiding said carriage in a path parallel to the axis of rotation of said card, means for accurately guiding thread from said carriage to said card, means coupled to said drive means for controlling the speed of rotation thereof, and means selectively coupling said drive means to said carriage for transmittal of driving force to said carriage to effect translation of said carriage.
Claim 9
Dependent Claim
29 words
The apparatus of claim 6 wherein said means coupling said drive means to said card holding means includes a transmission for selective control of the rate of card rotation.
Claim 10
Dependent Claim
39 words
The apparatus of claim 7 wherein said drive means is driven continuously and said means coupling said card holding means to said drive means includes a clutch for selective disconnection of said drive means from said card holding means.
Claim 11
Dependent Claim
43 words
The apparatus of claim 6 wherein said control means includes a working memory and means for inputting data to said working memory, said data defining a desired number of card revolutions and the color of a yarn to be wound during said revolutions.
Claim 12
Dependent Claim
67 words
The apparatus of claim 9 wherein said input means comprises a keyboard coupled to said working memory, said control means further including a permanent memory and the working memory further including a data-transfer channel coupling said working and permanent memories, whereby said data may be transferred to said permanent memory from said working memory for storage and retrieval of said data in and from said permanent memory.
Claim 13
Dependent Claim
14 words
The apparatus of claim 10 wherein said permanent memory comprises a magnetic tape recorder.
