SQF-Q8
When Sensor SQF-Q1 is deactivated, The Roller motor SQF-M4 is energized, 
and moves over the spine of the Booklet, pressing it up against the Set clamps, 
producing the Square fold look. The Encoder Sensor Q8 starts counting pulses by 
reading the Encoder Disc. When the correct number of pulses have been counted, 
motor SQF-M4 slows down. When Sensor SQF-Q2 or SQF-Q3 is activated, motor 
SQF-M4 stops.
When Roller motor SQF-M4 has reached it’s home position SQF-Q2 or SQF-Q3, 
Clamp motor SQF-M3 is energized, moving the Clamps upwards. Motor SQF-M3 
runs until Clamp motor Home position Sensor SQF-Q4 is activated / deactivated. 
The Clamps are now in their upper position. 
When sensor SQF-Q4 is deactivated, Transport Belt motor SQF-M1 and Belt 
Stacker motor ST-M1 (not shown in picture) together with Solenoids SQF-SOL1-
SQF-SOL4 are energized to feed out the set. When Outfeed sensor SQF-Q7 is 
Activated / Deactivated, Transport Belt motor SQF-M1 and Stacker motor ST-M1 
stop, Solenoids SQF-SOL1-SQF-SOL4 deactivate.
