Abstract

The subject matter of this specification pertains to improvements intended to be utilized in a ribbon inking machine having a frame, a drum mounted on the frame, a carriage movably mounted on the frame so as to be capable of being used with respect to the drum, a ribbon feed roller mounted on the carriage, a ribbon inking structure mounted on the carriage, and a ribbon takeup roller mounted on the frame. Such a machine is preferably constructed to include a pressing element mounted on guide rods so as to be capable of being moved towards and away from the drum. Solenoids are used to control the tension on bands mounted on the pressing element and passing around the guide rods. When they are tightened they hold the pressing element relative to the guide rods. A mechanical mechanism provided for raising and lowering the pressing element is located on the guide rods. Although this mechanism and these bands are intended for use in a ribbon inking machine as described it is considered that other uses will be found for them.
