The signature path exit motor (M30) turns on, pushes the signature exit guide [1] to the left and lamps the
signature and cover [2] in the nip of the signature exit rollers [3].
After the signature is firmly clamped in the nip of the signature exit rollers the grip motor: front (M24) and
grip motor: rear (M23) turn on and retract the main gripper [4] away from the sides of the signature. The
main grip lift motor (M22) turns on, raises the main grip unit [5] to its home position and stops.
The signature exit roller motor (M27) rotates long enough to lower the signature to reach the point where
the signature can be passed to the trimming unit and stops. The book grip motor (M43) turns on, pushes
the right book rotation plate [1] to the left and clamps the book [2] between the left and right rotation plates.
(The left rotation plate is stationary). At the same time cover guide motors (M15: Left/M16: Right) turn on
and close the left and right cover transport guides [3], [4]. Next, the grip unit rotation motor (M21) turns
on and rotates the main grip [5] counter-clockwise to its home position.
