  • Patent number: 6772886
    Abstract: The present invention relates to a bank note sorting apparatus. Known such apparatuses have the disadvantage of not being user-friendly since the transport path of the bank notes is not readily accessible to a user due to the elaborate mechanical design of the transport system. Bank notes that block the transport system due to faulty transport can therefore not be readily removed. In the present invention this disadvantage is avoided by the bank note sorting apparatus consisting of at least three parts, with one part disposed in the middle and at least two parts removable therefrom, thereby obtaining easy access to the transport system.

  • Publication number: 20030148840
    Abstract: A cog belt pulley system includes cog belt pulleys (10a to 10c) each with at least one flange (15 to 17) protruding in the radial direction beyond the toothed circumferential surface (11) and extending in the circumferential direction to limit slipping of the belt (20, 30, 40) at right angles to the circumferential direction of the pulleys (10a to 10c). Said flange is provided only as a segment over a limited part of the circumferential surface in the circumferential direction of the pulleys. A belt is mounted on two pulleys by the pulleys being rotated into a position in which the particular flange segments face each other. In this position the belt can be pushed onto the pulleys without colliding with the flange segments.
