We have heard of this problem many times, but the solution is worth
repeating.  Speed has nothing to do with the damaging rolls on rewind.
The damage on rewind is usually the fault of the brake on the take up
spool.

These brakes were originally placed to insure the rolls wind up
snuggly.  When the paper ages, and become brittle, this brake will
cause the paper to wander on rewind and the tightness of the take up
spool exerts pressure on the edges of the roll, and can cause damage.

Test your take up spool.  Does the spool spin freely with no roll on it
when you spin it by hand, when the rewind lever set on rewind?  If not,
see to it that it does.  This may require proper lubrication of the
take up spool bearings, and/or might require that the take up spool be
disconnected.  Yes, the rolls will be wound loosely, and will require
gentle tightening by hand, but it sure beats having rolls destroyed by
the drag on the take up spool.

My own Ampico rewinds at high speed, and I have never had any problems
with it damaging roll edges.
