PRINCIPLES OF OPERATION, Continued
FEED CYCLE
Strap is fed by high speed knurled feed wheel
and pinch rollers. During feed cycle, strap rides
on strap lead and does not contact knurled
tension wheel. Tension wheel at this time is
rotating in opposite direction to strap.
SLACK REMOVAL CYCLE
Slack is removed by high speed knurled
feedwheel and pinch rollers. Knurled feedwheel
is geared 3 times faster than knurled tension
wheel. Tension wheel has an over running clutch
so that it is free to rotate.
FINAL TENSION CYCLE
When the high speed knurled feedwheel stalls at
the end of slack take-up, knurled tension wheel
(geared down 3 times the power of the knurled
feedwheel) takes over and pulls final tension.
Knurled feedwheel at this phase slips at friction
clutch.
The lock nut must be tightened only to
the point where 65 lbs. ± 10 lbs. (289N
± 44N) tension is achieved before the
knurled feedwheel slips at end of slack
removal. If it is too tight, final tension
will be over ridden resulting in poor,
erratic tension.
