Abstract
Provided is a system and method of 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.
Claims20
A method of making a door, comprising the steps of:
- a) assembling a plurality of doors;
- and
- b) alternately receiving the doors into at least first and second presses of a pressing station and pressing the doors;
- wherein each of the doors includes a door frame having stiles and rails forming a perimeter of the door frame, and first and second door skins joined to opposite first and second surfaces of the door frame, respectively, to form a door;
- wherein each of the first and second presses includes pressing surfaces shaped to compress central portions of the first and second door skins to a greater extent than peripheral portions disposed about a perimeter of the first and second door skins so that surfaces of the central portions and the peripheral portions of the first and second door skins are coplanar with each other, and the peripheral portions are in contact with the stiles and rails of the door frame upon discharge.
2 more elements
A method for making doors, comprising the steps of:
- pressing doors in a pressing station having at least a first and a second vertically stacked presses, the first and second presses each configured to receive, press, and discharge at least one door having a door frame containing stiles and rails forming a perimeter of the door frame, at least two door skins, and adhesive;
- the first and second presses further being configured to press in alternating manner with respect to one another;
- wherein each of the first and second presses includes upper and lower dies shaped to compress central portions of the at least two door skins to a greater extent than peripheral portions disposed about perimeters of the at least two door skins, so that surfaces of the central portions and the peripheral portions of the at least two door skins are coplanar with each other, and the peripheral portions are in contact with the stiles and rails of the door frame upon discharge.
