ABSTRACT:
A sewing machine, or similar machine which consumes thread at a work station, has combined with it a thread color device located between the work station and a thread supply. The color device causes the thread issuing from it to have any one of a number of available colors, allowing stitches of different color to be made at the work station without changing the thread or rethreading the needle. The timing of a change in thread color at the color device with respect to the schedule of work performed at the work station, and the movement of the thread from the color device to the work station, are controlled so that a change in thread color occurs at the work station at substantially the same time as such change is desired in the work schedule performed at that station. This control may include a means for pulling thread from the work station, a means for performing a thread wasting routine at the work station, or a means for effecting a color change at the color device in advance of the need for such change at the work station with the timing of the color change at the color device being such that the color change arrives at the work station at the desired time in the work schedule.
