1. Description
Creaser module contains the lower blade having
a concave (recessed) section and the upper blade
having a convex (projected) section. The creaser
unit works to crease the paper perpendicularly to its
traveling direction.
2. Operation
The sensor plate provided coaxially with the cam
detects the top dead center of the upper blade to
control the DC motor. The lower blade also can
move up and down by a cam. The height of the
lower blade is set by the DC motor with an encoder,
and is specifi ed relative to the lower blade’s bottom
dead center at which the sensor plate is provided.
The crease depth is determined in this way.
