Alignment feed for rotary printer feed belt - has outlet cylinder of group connected to input cylinder of second group to form deformable parallelogram

摘要

The alignment feed for a belt has at least two impression groups. These each have an input cylinder and an outlet cylinder for the band. The outlet cylinder (7) of a first group is connected to an input cylinder (8) of a second group to form a deformable parallelogram. At least one of the output and input cylinders are connected respectively to displacement actuators (27,21,28). the actuators can adjust the cylinders for vertical and horizontal movement.
