  • Patent number: 3965327
    Abstract: A method and apparatus for cutting a predetermined pattern in a moving web of material, such as paper, cardboard or the like is disclosed wherein a laser beam is deflected by a series of pivotable mirrors. The pivoting of the mirrors is controlled so as to cause the laser beam to trace and cut a predetermined pattern. The laser beam moves only in rectilinear motion, as does the web of material to be cut. Since the directions of motions are not parallel, any pattern may be cut by controlling the relative speeds of the laser beam and the moving web of material.

  • Patent number: 3962531
    Abstract: A method of compounding thermoplastic polymeric material and fillers, including additives and agents, and unique compounded products. The compounding method comprises mixing the thermoplastic polymeric material in particulate form with particulate filler, and in progressive sequence melting the surface portion of the thermoplastic particles, blending the filler with said molten surface portion of the thermoplastic particles and removing the resultant blended melt and filler from the surface of the thermoplastic particles. The mixing and melting, and the blending and removing, are continued until the filler is substantially assimilated into the polymeric material and the thermoplastic particles become substantially diminished by melting and blending, or the method can be carried further if desired. The compounded product thus prepared is characterized by a distinctive stratified consistency.
