Method of operating a draw unit of a spinning preparation machine

Abstract

A method of operating a sliver draw unit of a spinning preparation machine includes the following steps: applying, by incremental rotary displacement sensors, signals to an electronic control and regulating device; determining from the signals the angular position and/or the rotary direction of at least one of the roll pairs of the draw unit during operation and standstill; and rotating at least one of the roll pairs into a predetermined angular position by controlling the electric motor driving that roll pair.
