Abstract

A process for controlling the operation of a textile draw frame wherein a plurality of fiber slivers are fed to the draw frame at a predetermined desired delivery speed includes monitoring the presence of individual fiber slivers delivered to the draw frame and decreasing the delivery speed of the draw frame if any of the monitored fiber slivers is indicated as missing from being fed to the draw frame. The process includes subsequently increasing the delivery speed of the draw frame if the respective missing fiber slivers are again indicated as being fed to the draw frame. The invention also includes a draw frame including apparatus for carrying out the controlling process.
