High Precision Printing Machine parts Safety chucks

The following represents the most common practice: · Wrap each roller with plastic film · It is evacuated between the roller and the plastic film. · Add desiccant. · Bubble wrap. · Plywood case

The new design ZLELE safety chucks provide speed, accuracy, simple, safety and effective connecting device for continuous motion shaft (air shaft), to avoid winding shaft from loosening or tightening during operation which to improve working efficiency and
product quality. It has Pedestal type and flange type and has several bayonet coupling options to match different air shafts.

Safety Chucks do three things
1. They provide for a quick change at the end of a production run (either winding or unwinding).Therefore, there is less down time during turn around and the more cost effective in operation.
2 . They provide a means of transmitting torque to the roll being wound / unwound. Torque in the form of a drive on the rewind end
of the operation and torque from a brake on the unwind side.
3. Finally, Safety Chucks provide for concentricity between centreline, or axis, of the Safety Chuck and the center line of the
Air Shaft. Less eccentricity between the Air Shaft and Safety Chuck results in less vibration and wear.
