Abstract: In a device on a spinning room preparation machine, for example a fibre flock feeder, carding machine, cleaner or the like, for supplying and/or discharging fibre material, a tray-like guide element having a guide surface co-operates with at least one conveyor roll located opposite, the fibre material being guided towards and along the guide surface. In order to provide a simple way of supplying and/or discharging fibre material without undesirable adhesion of fibres, the guide element located opposite the at least one conveyor roll is arranged to be set in vibration by at least one actuator.

Abstract: An apparatus on a spinning room machine, especially a spinning preparation machine, is arranged for monitoring an electric drive motor, which is connected to an electronic speed-setting and/or regulating device, a rotating operating element being connected to the drive motor. In order to monitor the drive motor so that no damage occurs even under different operating conditions, there is a device for automatically determining the loading of the drive motor during operation, which is connected to a device for comparison with pre-set values for the loading, to which there is connected a display and/or switching device which can be supplied with electrical signals in the event of departures.
