Abstract

1352429 Reinforced plastics panels PLASTEEL INDUSTRIES Inc 25 Aug 1971 [25 Aug 1970 2 March 1971] 39947/71 Heading B5A [Also in Division B8] A flat or curved panel, e.g. a pallet, is moulded by drawing a thermoplastics sheet on to a mould surface at a distance from which reinforcement in the form of bars 10, 12 as shown or cords 22, Fig. 10, not shown, are supported so that the sheet envelops the reinforcement and unites to form webs 18 which join the reinforcement to the face of the panel 19. A sheet of polyethylene, polypropylene, polystyrene, ABS, PVC, cellulose - acetate - butyrate, or acrylic plastics is heated while held in a curved frame 14 separately or in position on a curved mould 3 having perforations 7 through which a vacuum is applied to shape the sheet. Alternatively mechanical means may be used to shape the sheet. Metal reinforcing bars 10, 12 rest on spacers 13, 8 fixed to the mould, spacers 8 having slots to locate the bars. Fluted formers 26 produce the legs of the pallet which will become flat on cooling if the mould has the correct curvature. Alternatively a flat mould may be used and the curvature occurring on cooling removed afterwards. In other embodiments, not shown, the reinforcement comprises a grid of rectangular metal bars welded together and supported on a continuous ledge around the mould, or nylon, glass or hemp cords stretched taut.
