CA 2087700

This patent publication discloses a pneumatically operated roll stop particularly for paper rolls and a method for controlling said roll stop. The invention is based on the concept of providing the outlet line from the work chamber (8) of a pneumatic cylinder (17), which is connected to the stop arm of the roll stop, at that side of the cylinder actuated during the braking of the roll motion with a pulse-controlled valve (13) suitable for controlling the outlet flow rate from said work chamber (8) of the cylinder. Such a roll stop comprises a frame, at least one stop arm adapted to said frame with the help of a pivotal joint, said stop arm having a member adapted to its distal end, capable of making contact with said roll to be stopped, further two pneumatic cylinders (7a, 7b) connected by their one ends to said frame and by the other ends to said stop arm, and at least one control valve (12), connected by air lines (9, 11) to said cylinder (7), for the control of the function of the cylinder (7). The air line exiting from the work chamber (8) of the pneumatic cylinder (7) is provided with a valve (13) between the cylinder (7) and the air discharge point, said valve being capable of controlling air outflow from the line by way of pulsed open and closed operation of the valve (13). The invention offers smoother operation of the roll stop and prevents damage to the roll.
