<p>An apparatus for manufacture of foamed plastics laminated panels having; an array of press modules, each comprising; a pair of opposed spaced frame members movable relative to one another; adjustment means to adjust spacing between said frame members; hinge to allow a first frame member to move relative to a second frame member; clamp to retain, in use, said frame members in a predetermined spaced relationship, two outer skin layers, in use, are spaced and located on the opposing inner surfaces of the respective frame members; sealing members locatable, in use, between said frame members and two outer skin layers, to define a mould cavity between said opposed outer skin layers when said clamp is actuated, at least one inlet to introduce into said mould cavity a liquid foamable plastics material: respective reservoirs of liquid reactants, for producing a foamable plastic; and delivery means to deliver liquid reactants in predetermined proportions to respective mould cavities. The apparatus provides a method for producing laminated panels at high volume than currently available. The application also discloses a sleeve for connecting an elongated nozzle extensions (25) to an injection gun comprising an outer U shaped sleeve (22) having an aperture in its base to accommodate nozzle (23) on an injection gun; an inner tubular sleeve (24) screws onto the nozzle (23) and elongated delivery nozzle (25) containing a static mixer (26), engaged with an inner screw thread of the tubular sleeve (24).</p> |
