SQF-6-12
29 November 2006PRINCIPLE OF OPERATION
In Mode 2:
This mode is for booklets with approximately 12 to 16 sheets of paper that are
being Book folded.
The difference between Mode 1 and Mode 2 is, that the Stop gate motor SQF-M2
is stopped a little bit further out from the clamps according to number of pulses
from the SQF-M2 motor encoder. The result of this will be that the booklet will be
pushed out a little, when being compressed by the Set Clamps, compared to Mode
1.
In Mode
3:
This mode is for booklets with approximately 17 to 23 sheets of paper that are
being Book folded.
The difference between Mode 2 and Mode 3 is, that Stop gate Motor SQF-M2 is
stopped according to pulses from it´s encoder a certain distance from the clamps.
Also when Roller motor SQF-M4 has reached it’s home position, the motor SQF-
M4 reverses and starts moving in the opposite direction. The result of this is that

In Mode AUTO:
When a set passes the fold rollers in the BM 200, and forces them apart, sensor
BM-Q37 starts counting pulses by reading the movement of the cam. Based on
that information, the BM 200 decides which mode is the most appropriate. That
decision is then communicated to the SQF 200.
In all other respects the principle of operation is as already described.

folding action on booklets from approximately 6 sheets and up.
NOTE: When the Squarefolder is set to [Auto] and the booklet has less than ap-
proximately 6 sheets/booklet, the Squarefolder will bypass the Square folding
action, transporting the booklet out to the Belt stacker.
In Mode 4:
This mode is for booklets with approximately 24 to 30 sheets of paper that are
being Book folded.
The difference between Mode 3 and Mode 4 is, that Stop gate Motor SQF-M2 is
stopped according to pulses from it´s encoder a certain further distance from the
clamps.
