SUNRISE Printing Machine Prat Price Visibility Safety Chucks

Safety Chucks Introduction:

A safety chuck is a specialized quick coupling used for web handling operations. In order to maintain the expected tension in a web, a shaft from which a roll is being unwound must be subject to a constant level of torque from a tension brake. Similarly, a shaft onto which a roll is being wound must be subject to a constant level of torque from a motor through a slip / tension clutch. A safety chuck provides a means to transmit torque to a roll shaft as well as the ability to switch the roll shafts quickly and conveniently. Unlike most couplings, a safety chuck does not require loosening and tightening of screws or moving any component other than the shaft and the chuck itself. Tension clutches, brakes, and motors need not be moved or dismounted.
