Abstract: A sheet accepting apparatus comprises an inlet (210) for receiving one or more sheets. A transport system (217,350) extracts sheets from the inlet. A first detector (222) detects the passage of a foreign object with the transported sheet(s), the transport system being controllable to divert a detected foreign object to a foreign object collection position (215). One or more further detectors monitor sheets fed by the transport system. At least one store (205) is provided for storing accepted sheets. A controller is responsive to the detectors for controlling the transport system.

Abstract: A stepping motor with an electrical activation circuit for electrical control of its exciter windings, is made as a driving motor and also as a braking motor with an adjustable braking action. The predefinable braking action is achieved passively without any current feed into the exciter windings. For this purpose a stipulated impedance with an adjustable duty factor can be connected to each exciter winding. One such stepping motor that is controlled in its braking action is used in an arrangement in which a strip or filament material can be transported braked from a storage.
