Abstract
A drawing unit for drawing sliver includes first and second drawing roll pairs being spaced from one another in the direction of sliver advance. One drawing roll in each drawing roll pair is a driven roll. There are further provided first and second drive motors; a first torque-transmitting device connected to the first drive motor and to the driven roll of the first drawing roll pair for driving the first drawing roll pair in a forward sense for feeding the sliver; a second torque-transmitting device connected to the second drive motor and to the driven roll of the second drawing roll pair for driving the second drawing roll pair in a forward sense for feeding the sliver; an electronic control and regulating device connected to the first and second drive motors; a freewheel backstop operatively connected to the driven roll of the first roll pair for preventing rotation thereof in a reverse sense; and an incremental rotary path indicator coupled to the driven roll of the second roll pair for generating signals representing rotary data of the driven roll of the second roll pair.
