ABSTRACT:
Apparatus for forming fiber material into a length of sliver. The apparatus includes: a machine for receiving such fiber material and forming it into the length of sliver; sensors for monitoring the operation of the machine and providing signals representative of that operation; an analog/digital converter connected to the sensors for receiving the signals provided by the sensors and converting those signals into digital representations of the operation of the machine; a digital electronic control unit connected to receive the digital representations formed by the analog/digital converter and including a microprocessor having memories, a device for generating digital representations of desired values of selected operating parameters of the machine, and a device performing operational, regulating, control and display functions, the control unit being arranged to provide digital signals for regulating the operation of the machine; a digital/analog converter connected to the control unit for deriving analog signals corresponding to the digital signals provided by the control unit; and a controllable regulator controlled by the analog signals derived by the digital/analog converter for regulating the operation of the machine.
