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 with a press having upper and lower dies configured to impart a larger compression force toward a central area of the door skins. Wear resistant belts or membranes are provided to protect the door skins from being marred by the upper and lower dies during the pressing process.

A door pressing system for pressing interior passage doors, exterior entry doors, bi-fold doors, and/or closet doors features a multi-door pressing station including first and second presses, a loading device, and a discharging device. The pressing station is configured to alternatively move the first and second presses into operative alignment with the loading and discharging devices. The press in operative alignment delivers a pressed assembled door to the discharging device and receives an assembled door layup to be pressed from the loading device. The other press that is out of operatively alignment presses an assembled door received therein. Additional methods and systems are also provided.

An apparatus for loading and unloading a multiopening press for manufacturing fibreboard comprises a first endless conveyor movable through an upper opening of a press having upper and lower openings with an intermediate plate therebetween. The first endless conveyor is formed of a plurality of conveyor sections which are spaced along the first conveyor and connected together by at least one drive member. A second endless conveyor is movable through the lower opening of the press. The first and second conveyors move along first and second feed paths through the upper and lower opening of the press respectively. The first conveyor however intersects the second feed path with the at least one drive member positioned on the first conveyor to permit passage of a mat for making a fibreboard on the second feed path to the second conveyor when each of the conveyor sections is spaced away from a location of intersection of the first conveyor and the second feed path. A pivoting table is pivotally mounted upstream of the first and second feed paths with an end movable to intersect the first and second feed paths.

A rail mounted carriage supporting a multishelf press loader is reciprocable between a sheet charger, which loads an individual lay-up of sheet material onto each of the loader shelves, and a multiplaten press for processing such lay-ups. After all of the loader shelves are charged with lay-ups, swingable upright lay-up-centering rods slide all of the lay-ups simultaneously farther onto the loader shelves until the leading edges of the lay-ups abut against movable stops supported adjacent to the leading or press end of the loader. The carriage is moved to the press, and the stops are raised out of edgewise registration with the lay-ups, whereupon all of the shelves and their lay-ups are moved past the raised stops and into the open press between its platens. The stops then are lowered behind the trailing edges of the lay-ups and shifted a short distance into the press to slide the lay-ups farther into the press. The stops hold the lay-ups in the press as the shelves are slid out from beneath the lay-ups. The carriage then is moved back to the charger to position the multishelf loader for receiving the next batch of lay-ups as the previous batch is processed in the press.

Simultaneous removal from a multi-level press of all press trays carrying particle board panels is achieved with a press unloading installation. Such installation consists of a vertically movable press unloader cage having chain conveyor pairs, primary supports for the press trays and panels, and auxiliary supports for the trays alone after separation from the panels. The installation further includes a discharge device for removing the press trays from the auxiliary supports of the unloader cage. In order to shorten the return transport of flexible press trays, separation between the finished pressed particle board panels and the flexible press trays is accomplished in the press unloader cage.

Particle boards are manufactured by the use of a forming line in which particulate material such as wood chips intermixed with a binder is deposited, in the form of a mat, by a scattering station 3 onto mat carriers moving on a forming conveyor 1 past the scattering station. The mat carriers are loaded by way of an accelerating conveyor 4 onto a faster moving storage conveyor 5 and are then stacked in the tiers of a vertically movable stacker loader 13 which in turn feeds a consolidation press for consolidating the mat sections into particle board. After the pressing operation the particle boards are ejected from the far side of the press and the now empty mat carriers are returned via the stacker-loader and a return conveyor 8 to a forwarding station 2 which feeds the mat carriers back onto the forming conveyor 1 for re-use.In a particularly preferred arrangement a pallet is provided in respect of each tier of the stacker-loader and the mat carriers are loaded onto the upper surface of the pallet and thereby introduced into the press. The pallet serves to eject the finished board from the far side of the press and to return the empty mat carrier which is slung beneath the pallet.

HOT PRESS PANEL LOADING AND UNLOADING APPARATUS HAVING INDEXING MECHANISMS ASSOCIATINGF THE SPACES BETWEEN PANEL PRESS PLATENS WITH PANEL LOADING MECHANISM AND PANEL UNLOADING MECHANISM FOR MOVING THE LATTER MECHANISMS STEPWISE TO SUCCEEDING PLATEN OPENINGS. THE UNLOADING AND LOADING MECHANISMS OPERATE SIMULTANEOUSLY TO UN LOAD A PRESSED PANEL FROM ONE PLATEN OPENING WHILE A PRE-PRESSED PANEL IS BEING LOADED INTO THE NEXT ADJACENT
PLATEN OPENING FROM WHICH A PRESSED PANEL HAS JUST PREVIOUSLY BEEN UNLOADED.
