6.5.13 INITIAL FOLDING
The folder plate motor [A] switches on and drives the folder plate [B] forward to
push the center of the booklet into the nip of the folder rollers [C], giving the booklet
a partial fold.
This is a detailed cross-section of the operation described above. The timing of the
sequence depends on the size of the paper selected for the job.
The stack feed-out belt transports the booklet toward the paper exit [D] and stops
when the center of the booklet is opposite the nip of the folder rollers [E].
The folder roller motor starts to turn and the folder rollers [E] start rotating. Then
the folder plate motor switches on and pushes the folder plate [F] into the center of
the booklet, driving the booklet between the rotating rollers. The booklet [G]
(partially folded) then feeds out between the folder rollers.
The booklet exit sensor [H] detects the booklet when it leaves the folder rollers.
This sensor triggers the mechanism for the next phase of the operation.
