The pre-curling machine can go up to 1000 drum ends per hour due to the combination of a servo driven shuttle conveyor and a heavy duty pneumatic clutch-brake unit. The pre-curling roller is cam operated with a spring return and is machined double sided with 2 profiles. The roller can be adjusted in depth and height for optimal curling setting. Optional, lubrication can be added to the roller.
This machine can be supplied with compound installation including guns, valves and vessel. Before pre-curling starts, the compound is triggered. In 1 second compound is applied for 7 rotations before pre-curling. The speed of the machine with pre-compounding is reduced to 720 drum ends per hour.
