  • Patent number: 4319949
    Abstract: A heat sealing machine for producing a drum of spirally wound layers of thermoplastic polymeric sheet material heat sealed together having a rotatable horizontal shaft for receiving thermoplastic polymeric sheet material spirally wound thereon by rotation of the shaft; a heater adapted to be positioned between and adjoining a first polymeric sheet layer being spirally wound on the shaft and a prior layer wound on the shaft; and a support, for the heater, displaceable with respect to the shaft axis so that the heater can remain radially adjacent a drum surface on which another spiral layer is to be heat sealingly attached. A portion of the heater can be readily formable into cylindrical shell segments of varying radii when positioned between the two polymeric sheet layers.

  • Patent number: 4284396
    Abstract: Apparatus for vacuum molding a plurality of three dimensional geometrical shapes in a thermoplastic polymeric sheet having a molding plate, the surface of which has a plurality of three dimensional geometrical shapes, with said molding plate having an enclosing border, a molding face and a non-molding face; a gas orifice extending through the molding plate so that a gas can flow from one face of the molding plate to the other face; a mechanism to move the molding plate along a predetermined path; a mechanism to maintain a thermoplastic polymeric sheet, heated to a plastic condition, adjoining the moving molding plate molding face; a mechanism to releasably seal the heated polymeric sheet to and all around the molding plate border; a vacuum source to remove gas, from between the heated polymeric sheet and the molding face of the molding plate, through the gas orifice whereby exterior pressure can force the heated sheet against the molding face surface; and a mechanism for removing the molded sheet, after it co
