Patent number: 6168008Abstract: In a drive system for a mail processing machine a comparatively simple and clear design of the driving tracks and of the bearings for the respective shafts is obtained by feeding drive energy from a common drive motor to a bevel gear drive and a step gear drive. Thereby, the output shafts of the bevel gear drive and the step gear drive have identical sense of rotation because of the sense of rotation reversal within the respective gear drive. The bevel gear drive, at its output, provides a continuous rotation, and the step gear drive provides an intermittent rotation. From the output shafts of the bevel gear drive and of the step gear drive, respectively, driving connections can be led to the driving shafts for a continuously moved conveyor chain for documents and to an intermittently moved conveyor chain for documents, respectively.Type: GrantFiled: July 7, 1999Date of Patent: January 2, 2001Assignee: Bell & Howell GmbHInventors: Martin Sting, Axel Brauneis
