Bottom Flap Height Dimension ‘M’ Adjustment
Before making any machine adjustments, refer to
the shutdown procedure outlined in Section 6.5:
‘Shutdown’
. Bottom flat height Dimension ‘M’
provides a baseline datum for adjusting
Dimension ‘B’, so it is important to adjust
Dimension ‘M’ first.
To start with, ensure that you unlock the vertical
adjustment lock lever located on the frame arch
beaneath the magazine. Then adjust the bottom
flap height Dimension ‘M’ hand crank until the ‘M’
pointer on the inverted vertical calibration scale
on the machine arch matches the measured
bottom flap height. Note that the chain lock may
be on the opposite side to what is shown.
Note that the Dimension ‘B’ hand crank may
have to be adjusted alternately with the
Dimension ‘M’ hand crank in order to prevent the
case blanks from falling through into the
machine’s restrictive envelope. The injector plate
should act as a backplate. Ensure that the tops
of the stacked case blanks do not make contact
with the sensor mounted below the injector.
The ‘M’ adjustment is intended to adjust the
vertical position of the case blank in the
magazine so that the score or fold line for the
bottom flaps is level with the bottom of machine
conveyor side belts. The bottom flap fold line is
thus the ‘datum’ for the vertical position of the
case as it moves through the forming, folding and
bottom sealing of the cases.
If Dimension ‘M’ is correctly adjusted, the bottom
score-line on the cases will align horizontally with
the top of the ramp where the center ski is
mounted.
Check the ‘S’ box for Satisfactory Performance and ‘US’ box for Unsatisfactory Performance.
