ECTION
Other than the charge end skew bed, all standard 12' beds have a 4' skew zone designed for the
center of the bed. Hole punching in the side channel allow for a ¾" offset of the rollers over the width
of the bed.
NOTE
that this means wider beds have less of a skew angle than narrow beds and produce a less
aggressive skew.
About 2" of movement across the conveyor can be expected per 4'
maintenance skew zone on 16" BF conveyor, and 1" of movement on 34" BF conveyor.
A
sticker on the conveyor side frame indicts the 4’ skew area.
Maintenance skew beds are typically used in contact accumulation NBC lines over 80' which have
small product on them. After initial alignment by a charge skew bed, maintenance skew beds keep
products aligned. If an NBC conveyor requires maintenance skewing after installation, field skewing of
the middle section of a 12' bed is possible. The required skew pressure pan is already included in the
middle zone of the standard 12' bed. If product contacts the side channel, a wheel rail should be used.
The steps for field skewing these zones are listed on the following page.
Never skew rollers without a skew pressure pan installed. Belt damage will result and warranty
will be voided.
Do not over skew rollers, as it will cause premature belt failure.
