Abstract
A franking machine is disclosed comprising a carriage manually movable along a bed and a print drum carried by the carriage to make rolling engagement with a mail item supported on the bed. A toothed rack extends along the length of the bed and gearing on the carriage meshes with the rack to drive the print drum and an impression roller carried by the carriage. The gearing is arranged such that as the carriage is moved in a forward direction along the bed, a mail item gripped between the print drum and the impression roller is fed along the bed in the reverse direction so that the length of traverse of the carriage, and the length of the bed, is less than the length of the franking impression to be printed.
Claims7
A franking machine including a base member;
- a carriage movable from a home position to a final position along the base member;
- a rotatable print drum carried by the carriage;
- drive transmission means interconnecting the carriage and the base member to cause rotation of the print drum through a franking impression printing revolution in response to movement of the carriage away from the home position to said &inal position in a franking printing operation;
- and an impression roller mounted on said carriage and resiliently urged toward said print drum to apply impression pressure to a mail item located between said print drum and said impression roller.
