Abstract
Abstract Disclosed is a device for making panels, such as wall panels, particularly of the type having metallic skins with a foam insulation therebetween. A movable carriage supports temperature controlled mold platens which can carry the skin material and which swing about a common axis to open and close. The carriage is positioned under a moving nozzle assembly which dispenses the insulation material between the skins. Means are provided to form male and female ends for the panels for interlock with other panels. In addition, means are provided so that the apparatus can be readily adjusted to form panels of varying widths.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
142 words
Apparatus for making panels having two sidewall forming skins and an insulation material therebetween comprising two mold platens, means selectively swinging each said mold platen about a common axis from an open position for loading the skins and unloading the panels to a closed position for receiving the insulation material, means selectively holding a skin on each said mold platen, core means extendable between said mold platens to close one end of the panel, nozzle means making multiple passes between the skins to dispense the insulation material between the skins, the first of said multiple passes dispensing the insulation material on said core means, and lid means activated during the last pass of said nozzle means to close the other end of the panel and to thereby form with the skins and said core means an enclosed cavity for the insulation material.
