Abstract: An apparatus (2) for flatting, punching or stamping a material (40) introduced into the apparatus (2), said apparatus (2) comprising a first cylinder (14) provided with an outer layer configured for flatting, punching or stamping the material (40); a back-pressure cylinder (16) extending parallel to the first cylinder (14) and an adjustment mechanism (22, 22?, 28, 28?, 34, 34?, 36) for adjusting the distance between the first cylinder (14) and the back-pressure cylinder (16). The adjustment mechanism (22, 22?, 28, 28?, 34, 34?, 36) comprises a first contact member (22) and preferably a second contact member (22?) brought into contact with the bottom portion (circumference) of the first cylinder (14). The contact member(s) (22, 22?) are mounted on a structure (34, 34?) being movably mounted relative to the back-pressure cylinder (16).

Abstract: In an actuator, a quick release unit is introduced in a transmission between an activating element and a reversible electric motor for disengaging the activating element (5) from the electric motor and the part of the transmission (6) which is disposed from the motor to the quick release unit. This quick release unit comprises two cylindrical coupling parts (8, 9) provided with axially extending and mutually engaging torque-transferring means (21a, 21b), and where the two coupling parts (8, 9) are mutually axially displaceable and kept in engagement with each other by a spring (25). The two coupling parts may be displaced mutually against the spring (25) by a release mechanism, so that the torque-transferring connection (21a, 21b) between the two coupling parts (8, 9) is interrupted. The quick release unit may be made compact, and especially in connection with a worm wheel (6) with a cylindrical part on the side it may be substantially received in the cylindrical part.
