(5)Pull tractor mechanism (option) (See Figure
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.
