3950 Series RegisterTable

Type of Balls

The number and type of balls in the ball cage

(1) depend on format and type of paper.

Always try to use as few balls as

possible. Balls not needed for a

particular job should be removed

to avoid wear of the transport belt.

It is recommended to use the following balls:

Paper grades below 60 GSM:

Plastic balls

Paper grades from 60 - 150 GSM: Plastic balls, every 6th should be a steel ball

Paper grades above 150 GSM:

Mainly steel balls

In the infeed section (the first 4 to 6 balls) it is recommended to always use one

or two steel balls.

For very light paper grades every second ball opening should be left free.
