Box Drive Belt
Tension adjustment of the drive
belts may be required during normal
operation. Belt tension must be
adequate to positively move the box
through the machine and they should
run fully on the surface of the pulleys
at each end of the frame.
The idler pulleys on the infeed end
are adjusted in or out to provide
proper belt tension. Each belt is
adjusted separately. Belt tension is
obtained by tightening the adjustment
screw so that a moderate pulling force
of 3.5 kg [7 lbs] applied at the mid
span, as shown in Figure 13-4, will
defl ect the belt 25mm [1 inch]. This
will assure positive contact between
the belt and the drive pulley on the
discharge end of the taping head.
To adjust belts, see "Maintenance –
Drive Belts", steps 3 and 7.
