ABSTRACT:
Composite panelling of upper and lower metal skins with side configurations for interlocking and a rigid foam core are continuously made by feeding separate upper and lower skin panels secured together by preassembled rigid foam end dams continuously past a foam station having a small height mixing head mounted on cross slides to lay down a zigzag pattern of foam between the skins, with the first and last transverse run of foam being parallel to the ends of the skins. A mixing head is such that valves are located within the head so that the two foamable chemicals do not contact each other until they are fed into the mixing chamber wherein a mechanical mixer mixes them immediately prior to being deposited, which mechanical mixer and valves are of minimum height and fully insertable within the molding space between the skins. A drive motor for the mixer is located in the main body supporting the mixing head, which main body does not enter into the mold cavity. The valves and cross slide are operated automatically, and if there is too long a delay between foam deposits, the chemical valve faces, mixing chamber, mechanical mixer and other parts exposed to the mixed chemicals will automatically be flushed with a solvent and air.
