Paper Paths and Components
Chassis
The chassis structure consists of two high strength polymeric supports held together by
two sheet metal tie bars (see figure below). The two tie bars are placed a distance apart
to yield a high moment of inertia. This results in a structure of high rigidity in torsion and
bending. Besides structural purposes, the lower tie bar is used to mount the paper trough
and the higher tie bar to hold the upper paper guides.
An open structure like this can accommodate flexibility in designing for removable
trough from the back. Moreover, the modularity allows ease of assembly at the top level;
the carriage system is mounted at the top and the dual bin is mounted at the bottom on the
two supports.
The primary datum of the system is on the supports, thus minimizing the tolerance stack-
up on critical subsystems like the drive, input and carriage. Polymeric material of the
supports allows flexibility in complex designs to support these subsystems.
