that
there
can
be
nearly

the
concepts
for

by

against

core.
This
system
worked

speeds
up
to

ft/min.
The

should
be
driven
for
best
results
because
there
is
considerable
rolling
friction
from
the
wedging
forces
between
the
backup
roller
and
the
winding
roll.
The

conditions
seemed
to
be
optimum
when
about
80%
of
necessary
winding
power
is
supplied
by
surface
friction
from
the
backup
roller
and
20%
of
the
winding
power
from
the
