Abstract
Disclosed is a process and apparatus for stopping the drawing action of a draw frame whenever sliver breaks. The sliver is pneumatically conveyed into the field of influence of a sensor which generates a signal indicating the presence of the broken sliver therein. This signal is used to stop the draw frame, thus eliminating the production of sub-weight sliver or roving.
