operating 
in 
a 
compound 
bow 
so 
that 
there 
can 
be 
nearly 
uniform 
contact
along 
the 
curved 
contact 
locus 
of 
the 
winding 
roll. 
Figure

shows 
how
this 
was 
successfully 
commercialized 
on 
slitting 
machines. 
Figure 
8.16
shows 
the 
concepts 
for 
forming 
a 
compound 
bow 
by 
preloading 
the 
lay-
on 
roller 
against 
the 
new 
core. 
This 
system 
worked 
well 
on 
thin 
capacitor
and 
thermal 
transfer 
type 
lms 
at 
speeds 
up 
to 
1500 
ft/min. 
The 
backup
roller 
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 
drive 
power 
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 
winder 
drive. 
There 
were
several 
fairly 
rough 
lm 
types 
running 
on 
these 
machines. 
The 
centerline
of 
the 
lay-on 
roller 
should 
be 
located 
a 
small 
distance 
above
