Tips

Air chucks are an easy to operate method of holding cores and rolls in unwind and rewind applications. They are typically supplied as a standard, thru bore design. Often times, the only variable when ordering air chucks is the thru bore size. It's this standard "off the shelf" nature that makes air chucks a very attractive option where initial costs are a concern.

Air chucks operate by inflating and deflating. They are designed so that their deflated diameter will allow them to be easily slipped inside your core. Once inserted into your core they are inflated with an inflation device so that they grab and deliver torque to the roll core. This easy, rapid inflate and deflate procedure is an effective option where fast roll changes are desired.

End plugs can be used on the end of the core opposite the air chuck. End plugs do not inflate or deflate. Typically they are manufactured in a cone shape that allows the core to be easily slide over them. They simply provide support for the core where web widths are wider than the air chuck. End plugs are normally supplied with a core stop flange to ensure rolls are always placed in their proper position in the machine.

In today's economy, cost effective options to speed up processes are always desired. Air chuck / end plug combination of core holding may be the best value for your operation.
