Abstract
A system and method for making a door having first and second door skins and an internal frame. The top and bottom surfaces of the frame are coated with an adhesive and the frame is placed on a first door skin. The second door skin is then placed on the opposite surface of the frame. The assembled components are then pressed to bond the first and second door skins to the frame with a pressed having platens. Movable shims may be used to vary the pressed force and pressing area.
Claims20
A door press for pressing door assemblies of different sizes, comprising:
- a first die comprising a first fixed surface;
- a plurality of first movable shims having first movable shim surfaces, the first movable shims being movably connected to the first die to move between at least a raised position in which the first movable shim surfaces are substantially flush with the first fixed surface and a lowered position in which the first movable shim surfaces are recessed into the first die relative to the first fixed surface;
- and
- a second die comprising a second fixed surface facing the first fixed surface, at least one of the first and second dies being movable towards and away from the other for pressing a door assembly between the first and second dies.
1 more element
A door-making system, comprising:
- at least one adhesive coating station for applying adhesive to at least one of a door frame having opposite first and second surfaces, a first door skin, and a second door skin;
- at least one assembly station for joining the first and second door skins to the opposite first and second surfaces of the door frame, respectively, to form an assembled door;
- a door press comprising
- a first die comprising a first fixed surface;
- a plurality of first movable shims having first movable shim surfaces, the first movable shims being movably connected to the first die to move between at least a raised position in which the first movable shim surfaces are substantially flush with the first fixed surface and a lowered position in which the first movable shim surfaces are recessed into the first die relative to the first fixed surface;
- and
- a second die comprising a second fixed surface facing the first fixed surface, at least one of the first and second dies being movable towards and away from the other for pressing a door assembly between the first and second dies;
- and
- at least one material handling device for transporting the assembled doors to and from the door press.

A method of pressing a door assembly, comprising:
- providing a door press comprising
- a first die comprising a first fixed surface;
- a plurality of first movable shims having first movable shim surfaces, the first movable shims being movably connected to the first die to move between at least a raised position in which the first movable shim surfaces are substantially flush with the first fixed surface and a lowered position in which the first movable shim surfaces are recessed into the first die relative to the first fixed surface;
- and
- a second die comprising a second fixed surface facing the first fixed surface, at least one of the first and second dies being movable towards and away from the other for pressing a door assembly between the first and second dies;
- and
- selectively adjusting the first movable shims in the raised position or the lower position so that a combined area of the first fixed surface and the first movable shim surfaces of the first movable shims in the raised position corresponds to a surface area of a face of the door assembly;
- and
- pressing the door assembly in the press.
