摘要： Individually programmable compression rolls for an accounting machine having a rotatable platen which is split into first and second parts, with the rolls being spaced along the platen. Each roll is rotatably mounted on a roll arm which is pivotally mounted on a supporting shaft having a spring thereon to resiliently urge the associated roll against the platen. Each roll arm has first and second actuating arms associated therewith, with the first arm being fixed to rotate with a first actuating shaft but being axially slidable thereon between first and second positions, and with the second arm being fixed to rotate with a second actuating shaft but being axially slidable thereon between first and second positions. In the first position, each actuating arm is out of contact with its associated roll arm, and when selectively axially moved to the second position, the actuating arm is aligned with the associated roll arm enabling the associated actuating shaft (when rotated) to pivot the roll arm and move the associated compression roll away from the platen. Separate actuating linkage is provided for the first and second actuating shafts.
