An apparatus in combination with a carding machine and a regulatable tuft feeding device for evening a running sliver produced by the carding machine. The assembly has a fiber-handling roller forming part of the carding machine, a motor drivingly connected to the roller, an rpm-setting device connected to the motor, a desired value setter connected with the regulatable tuft feeding device; a measuring device for determining momentary values of mass of the running sliver; a regulator connected to the measuring device and to the rpm-setting device for controlling the rpm of the roller as a function of the sliver mass sensed by the measuring device. There is further provided a limit value indicating device connected to the rpm-setting device for responding to predetermined setting limits.
