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.
Claims11
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.
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.
