Movement of the dummy Pin
A dummy pin is provided between the fixed pin and the roll, on both sides of
the bin unit.
The dummy pin prevents the bin unit moving down too far. The dummy pin en-
gages with the lead cams and the fixed pins after the bin unit has reached its
lower limit.
The fixed pins are in this way always above the cams, thereby keeping the bin
unit above its lower limit.
