I need some help. I have heard many varying and conflicting reports
of the paper travel speeds of original A and O roll machines, not
modern buildups with modern spool frames.
So what I need is for volunteers with access to originals to do the
following:
1. Place a roll on the spool frame. You'll probably want to use a
new recut.
2. Mark, with a pencil, a point on the roll; back it up, then start up
the machine. When that mark crosses the tracker bar, start a stopwatch.
3. After exactly one minute, make another pencil mark and stop the
roll. Measure the distance between the two marks, and please send me
that distance.
For 'A'-roll machines, adjust the wheels to the tempo that seems to be
the one used most. For 'O'-roll machines, please place the spool frame
drive belt first on the smaller spool frame drive pulley, then on the
larger; do the test for both and tell me the results for both.
Now, why do I need this? Because the Christmas roll paper travel
speed requirement (the tempo) is apparently faster than that available
on original machines. I thought I had it right, but apparently I did
not, so some customers are not hearing it at the correct tempo (making
it sound dull as dishwater).
The "Theory-of-what-SHOULD-be-the-right-speed-because-the-manual-says-so"
notwithstanding, the only way I can be sure of the correct tempo is by
some kind soul doing the steps mentioned above. I want some real live
empirical evidence, measured on real live original machines.
Thanks in advance, and I'll post whatever results come back, if any.
