End View of Portable Top and Bottom Sealing Machine. Only One Operator Needed retaining all the original strength of the side walls plusthe additional stiffness of a perfectly sealed top andbottom. An automatic starting and stopping device controlsthe application of power in such a way that each case isonly carried into the machine its own length. Poweris thus shut off and the machine stops until the next. The operation of this ma- \ chine is simple. The operator I applies the silicate and moves I the case into the machine. The I guides bring the flaps of the case closely together, both top and bottom, thus starting the case through the machine in rectangular form. These guides can be easily and quickly adjusted to any size case. The upper rollers shown below apply a strong,flexible pressure against the top of the case. This pres-sure adapts itself to any irregularities in the surface ofthe case during its travel through the machine, whereasa fixed weight would press merely upon the high roller is spring free at each end and all rollersare independent of each other. Any bumps or depres-sions in the case are reached by each roller. The thick canvas belts, both top and bottom, are of such width as to lie between the side walls of the case. Consequently there is no crushing force exerted on the side walls and the case emerges from the machine Side View of Portable Top and Bottom
