Open Coil Pressing Roll
Used for pressing coil after open the bale strip, prevent coil getting lose, and can depend its power to make few lose coil become tight
Swing of uncoiling roller driven by oil cylinder, rotation driven by hydraulic motor.
In normal running, uncoiling roller lift.
Hydraulic support: help to support uncoiler main shaft. Through hydraulic cylinder and toggle rod device, support arm raise to support shaft ends, improve shaft loading capacity, support ends is waist drum roll (surface chromium) structure.
