Abstract
The passage of material through a textile spinning or twisting machine is regulated through operation of a control element associated with the movement of said material. Light reflected from the moving material is converted into a variable electrical signal which is then modulated and used to operate a light-emitter. The modulated output of the light-emitter is sensed by a receiver located remote therefrom, but in direct-line-of sight, into an electrical command signal for operating the control element.
