ABSTRACT:
An apparatus for the continuous production of prefabricated insulating panels is provided, which includes a feeding station for a lower metal sheet and for an upper metal sheet, a rolling-mill train for shaping the sheets, a furnace for heating the sheets, a device for injecting expandable plastic material between the sheets, a joining unit for joining the sheets together and for holding the expanded plastic material in place, and a cutter for cutting the finished panels. The joining unit has two, link-type upper and lower conveyors for the sheets shaped by the rolling-mills, at least one of which is adjustable, so that the distance between them may be regulated according to the thickness of the panel, with the conveyors being arranged to revolve continuously around rollers which rotate about a horizontal axis. An article produced by the apparatus is also provided.
