A method for measuring the thickness of a layer of pasty or dough-like material on a moving surface (5) wherein a movably supported measuring roll is contacted with the layer and wherein during the movement of the surface provided with the layer the deflection of the measuring roll crosswise to the moving direction of the surface is detected with a sensor generating an output signal, whereat a parameter of this output signal is in a functional relationship with the magnitude of the deflection of the measuring roll, or of the thickness of the layer, respectively. To maintain the accuracy and to prevent the coiling up of the layer to be measured on the measuring roll, a defined braking force is exerted thereon.

Method for measuring the thickness of a layer and apparatus for carrying

An apparatus for sorting particles of a bulk material moving on a transport ribbon (38) comprises an electro optical monitoring unit (101) above transport ribbon (38) for detecting the particles to be sorted out. Jet nozzles (45, 46) are controlled by a signal emitted by this electro optical monitoring unit (40), the jet nozzles being provided at the side opposite the bulk material of transport ribbon (38), which consists of an air permeable material. By means of the gas jet passing through transport ribbon (38), the particles to be sorted out are lifted off from the transport ribbon and are thrown into storage containers (47, 48). The bulk material is passed through a gap between rollers or grinding elements to provide flake-shaped particles which are then observed to provide first and second measurements which are subtracted from each other. A vibrating conveyor 87 with feeding channels 87.1 separate particles for disposition upon a ribbon 538 with the aid of a jet nozzle n.
