ABSTRACT:
A carding machine has a main carding cylinder, an electromotor drivingly connected to the carding cylinder and a control device, including a memory, for controlling the rpm of the carding cyliner. The main carding cylinder has a starting phase during which the main carding cylinder is accelerated to a working rpm and a stopping phase during which the main carding cylinder is decelerated from a working rpm to standstill. The method of operating the carding machine includes the steps of storing in the memory material-specific sets of rpm values for the starting phase and sets of rpm values for the stopping phase; and controlling the rpm of the main carding cylinder in the starting and stopping phases by the control device in accordance with respective rpm values stored in the memory.
