Abstract: A conveyor apparatus includes a drive unit, a connection interface which transmits analog signals, and a drive control module which is coupled to the drive unit and to the connection interface via signal technology. The drive control module receives analog control signals via the connection interface in an operating state and controls the drive unit as a function of the analog control signals, outputs digital diagnostic signals via the connection interface in a digital communication state, and switches from the operating state to the digital communication state upon receipt of a switchover command. The switchover command is made up of a predetermined analog control signal or a predetermined sequence of analog control signals.

Abstract: The adherence of an individual fibre embedded in a polymer matrix is determined by a drawing experiment in which the fibre is drawn out of the polymer matrix and simultaneously the pertaining force-distance diagram is registered. To this end a test sample consisting of the polymer matrix with the individual fibre embedded therein is manufactured by melting down a quantity of polymer present in granular or powder form on an object holder, the individual fibre is dipped into the molten polymer mass and the polymer mass is subsequently cooled down below the melting point. Subsequently the object holder with the test sample adhering thereto is brought into a force-distance measuring device, and the free end of the fibre is fixed to a chucking device moveable in the direction of the fibre.
