(5) Pull tractor mechanism (option) (See Figure 2-12.)
Bottom feed of continuous sheets is possible only when an optional pull tractor unit is
installed.
The rotation of the platen is transmitted to the idle gear of the pull tractor unit through
the platen gear at the left end of the platen. The rotation of the idle gear is transmitted
to the drive gear, and continuous sheet forms are fed by the pull tractor being rotated
through the sheet feeder shaft.
