Abstract
A portable, motor operated machine is shown having a box-like housing or work surface that supports an electric motor on one side thereof. A removable elongated shaft or spit is connected into a receiving socket of the motor so as to be turned thereby. The shaft extends transversely across the housing or work surface, and there is a quick-releasable shaft-bearing mounted on the opposite side of the housing for supporting the other end of the shaft. A sheet of newspaper is adapted to be attached to the shaft for winding the paper onto the shaft as the motor slowly turns the shaft. A first pressure plate is hingedly supported near the rear edge of the housing, and it is urged into engagement with the paper roll. A second pressure plate is hingedly supported from the rear edge of the housing and it carries the first pressure plate means thereon. An elongated guide roller is positioned adjacent the front of the machine below the shaft for applying tension to the paper. Both pressure plate means serve to increase the tension force on the paper being rolled so that the paper roll or log being formed is tightly wound, and, therefore, will be slow burning and longer lasting.
