Unwind Guiding sidelays the entire roll of
material to maintain a consistent edge position as the web enters into
the process. An AccuGuide Unwind guide assembly positions the web edge
to the guide point. The edge detector is stationary and located
immediately following the last shifting idler roller on the unwind
stand.
An unwind guide eliminates problems such as uneven, telescoped or poorly
wound rolls.

Winder/Rewind Guiding is accomplished
by moving the roll of material to match the edge position of the web as
it exits out of the process. An AccuGuide Rewind chases the web to keep
it aligned properly on the rewind core. The rewind edge detector is
attached to the moving rewind stand and is positioned on the upstream
side of the last fixed idler roller.
Rewind guides create rolls with precise, even edges or can be used to
oscillate, eliminating gage band problems. |
