  • Patent number: 6125901
    Abstract: A door is made from a rigid core plate, two side bars, two end bars, a pair of face panels, and a pair of cover sheets. The core plate and bars are cut to respective sizes, and then the bars are manually fitted around the core plate, are pressed against edges of the core plate to form a door core, and are secured together at corners of the core. This core is displaced on an upstream core conveyor to a core-holding station. One of the face panels is loaded manually onto a face-panel conveyor and fed thereby through a glue applicator to a face-panel holding station and one of the cover sheets is manually set in a cover-sheet holding station. The one cover sheet is picked up and laid in a stacking station, then the one face panel is picked up and set atop the one cover sheet, and then the core is picked up and set atop the face panel.
