Reel-up with separately acting actuators for influencing linear pressure

摘要

A reel-up comprises a surface winding drum; two rails to support a reeling drum; and secondary carriages movable linearly along the rails and provided with press devices to press against the reeling drum to maintain a predetermined linear pressure in the nip between the surface winding drum and the paper reel as it increases in size. Each secondary carriage comprises an actuator arranged to press the press device against the reeling drum with a predetermined force to control the linear pressure at each set position of the secondary carriage without influence from the actuator which sets the secondary carriage depending on the growth of the paper reel.
