AutoFlat® Automatic Shape Correction
AutoFlat is a patented leveler control system that takes automation
to the next level. The system reads the shape of the strip
as it leaves the leveler and by closed loop control automatically
adjusts roll
bending to achieve and maintain flat strip. The
system works on the fly and provides a dynamic readout
of strip
shape.
AutoFlat will seek the correct flight positions automatically,
and dynamically controls work roll bending
even when the
incoming strip changes shape.
The AutoFlat system relieves
the operator from adjusting the roll bending on the leveler.
Results are
consistent
flat strip
regardless of operator expertise and training.
Machine
Concepts offers AutoFlat with two types of shape sensors:
Air bearing type and displacement
type. Each
type uses a different
principal to sense shape and each has pros and cons
compared to
each other. Both require tension on the strip.
