Inserting process
• Once the envelope is on the insert table, the fingers solenoid (So1) is activated. The fingers are moved forward
into the envelope. The envelope stays in place, it is fixed between the two rollers (11 and 12).
• Now the document set is inserted. The set leaves the fold unit (transported by rollers 27 plus 28 and by 13
plus 14), is detected by the insert table photocell (PH9) and passes below the fingers before it enters the
envelope.
• When the insert table photocell (PH9) detects the trailing edge of the set, the set is inserted.
Envelope exit process
• Then a number of actions take place: (a) The clutch (CL8) is activated to release the flap and to feed a new
envelope to the insert table. (b) The insert table solenoid (So2) is shortly activated, resulting in the ejection
roller (16) moving down. (By spring action, after switching So2 off, these driven rollers are pulled high again.)
Now the envelope is rejected from the insert table. So2 is deactivated after the complete passage of the filled
envelope.
• The filled envelope passes rollers 17 and 18, the moistening brushes, the sealing track rollers (19 and 20)
and the lower sealing roller (22) plus its counter roller (21).
• Now the photocell (PH11) is triggered.
• The upper reverse roller (25) is held high (i.e. this roller doesn't contact the lower reverse roller 24) by a spring.
• A certain time after triggering the PH11 the sealing solenoid (So3) is activated. The envelope is between the
upper and lower reverse rollers.
• By the So3 action the upper reverse roller now is temporarily lowered.
• Given the turning direction of the lower reverse roller, the transport direction of the envelope is abruptly
changed from an "upstream" to a "downstream" direction. Assuming that the trailing envelope edge has
passed 21 and 22, this is now the leading edge of the envelope being transported through the sealing rollers
22 and 23.
• After passing the sealing rollers the envelope is exited to the exit.
• The photocell (PH11) is restored to its rest position.
• The exit photocell (PH10) monitors the passing envelope.
