10. AIR FEEDER PBA 38
Principle of
Operation
The air feeder PBA 38 consists of a feeder and a register table.
It is suitable for handling a wide variety of papers - uncoated papers as well as coated,
freshly printed or thin papers.
The sheets are separated by air and vacuum.
Air is supplied from the bottom of the stack both on the left and right side,
separating the paper in the stack which now floats in a cushion of air.
A rotating suction drum can then separate the sheets from the bottom of the paper
stack.
This principle has the advantage that paper can be continuously reloaded with the
machine running. There is no need to stop the machine.
On the register table, a transport belt, which runs at an angle, moves the sheets
against a register rail.
