How it works:
Shaft and core chuck rotate as one member in bearings and can be driven or
braked. Operator loads material onto core chuck and inflates. While core chuck
is rotating, operator can grab the adjusting nut with one hand and turn the
adjusting screw with the other hand. This unique feauture allows the machine
to continue running without the need to shut down the line for adjustments
in axial postion of web. This is the fine adjustment / lateral adjusting feature.
Typical adjustment range of adjustment is +/-1/2". Larger adjustment
ranges are available.
To make coarse adjustment to roll position, lock the adjustable core stop along
the bar in the desired location. When roll is loaded, it will hit against the
adjustable core stop and postion the roll.
