The collating area
• The collating area consists of a set of rollers (46, 50, 53, 56 and 60) that can be driven in both directions by
the collator motor (M1), and a set of counter rollers (47, 48, 49, 52, 54, 55 and 58).
• In the reverse direction of the collator motor (M1), documents are fed into the collator area. In the forward
direction they are moved out.
• The entry of the paper into the collator area (not the leaving of paper!) is monitored by the collating area
photocell (PH5).
The collating process
• Documents are fed into the collator area from the vertical track, or back into the collator area in the second
stage of the shunt process
• The documents are aligned against the relevant automatic document stoppers (51, 57 or 59).
• During shunting, the collator motor (M1) first turns in the forward direction, then in the reverse direction.
• Documents are exited from the collator to the fold unit if a set is complete. In that case both the collator motor
M1 (forward direction) and the folding forward clutch (CL4) are activated.
Short shunt
Document folding
The paper of a completed set leaves the collator area. This is detected by the folder entry photocell (PH6).
First fold
• The fold input rollers (42 and 43) transport the paper to the first fold table. The flap (41) moves up. Paper that
enters the first fold table will be directed in upward direction.
• At the appropriate time, the flap (41) moves back and the fold plate (40) moves forward. This is the first fold.
• Directly after the fold has been made, the fold plate (40) returns to its rest position. The movement of the fold
plate (40) and the flap (41) is controlled by the first fold table clutch (CL6). The clutch drives the curve gear
(37). The axle for the curve gear also carries the brake disc (38). Slotted photocell (SPH3) monitors the status
of the curve gear.
• The 360 degrees fold cycle of the brake disk consists of a 120 degrees part (flap upwards) and a 240 degrees
path (flap downwards plus “karate” action of 40). The brake disc is mechanically loaded by a positioning lever
and a torsion spring. The hinge axle (39) also carries the lever for the actuator of flap 41. In this way all
movements related to the first fold table are synchronized.
