2.6.2 The feeder paws
Four feeder paws pushes the material
down towards the conveyor belt. In
this way the material is fixed and kept
in place during the belt movement.
The position of the feeder paws along
the Y-axis is adjustable. To release or
lock, a locking knob is available.
It is also possible to disable the
operation of a paw by closing the air
switch to the paw (the blue handle).
It is a general rule that at least two
paws should be inside one sheet of
material.
The air pressure to the two air cylinder systems is adjustable. Maximum pressure should be applied
to the belt clamp.
The pressure to the feeder paws should be kept as low as possible, as increased pressure increases
the friction between the belt and the table.
2.6.3 Vacuum reverse
In order to minimize the friction between the conveyor belt and the cutting table, an air blow is
creating an air pillow below the belt during the belt movement.
Two vacuum valves and a fan provides the air pillow as illustrated:
Vacuum ON

During normal operation, the valve to the fan is closed while the valve to the vacuum pump is open.
In this case, you have vacuum on the cutting table.
When the valve to the fan is open and the fan to the vacuum pump is closed, you have an air blow
out from the tabletop.
