ABSTRACT:
A programmable electronic control system is provided to control the feed devices which supply different threads at different speeds in a spinning or twisting machine in order to produce yarn with special effects of color or shape at intervals along the yarn. The control system is supplied with clock pulses synchronous with the machine at intervals corresponding to a unit length of the basic thread feed. The length of a program module is determined by a settable pulse divider operating on the clock pulses and the resulting pulses are fed to a settable counter which determines the points in the module at which changes take place. Provision is made for repetition of program units a selected number of times and for interruption of the program at a random point.
