Apparatus and method for detecting sliver feed or standstill uses comparative measurements over a time-lapse to determine sliver movement. An identical reading in two or more sequential measurements indicates the sliver is not being conveyed, that is, it is either lying motionless or is absent altogether. Signals relating to the sensed standstill may be further processed in the machine control. The sensors are measuring elements capable of detecting thickness of the sliver and may be mechanical, optical or the like.
