Abstract
The invention relates to an wood-gluing system enabling the continuous production of glued pieces of lumber for panels and the like. The system includes a deck, a horizontal displacement system for an advancing lumber across the deck, a braking system, a one-way clamping system and an upstream pressure system. The system may be used in conjunction with finger-jointing processes or with single pieces of lumber and may be used for the production of both furniture grade and construction grade wood products.
Claims26
An apparatus for applying a consistent clamping pressure between a plurality of boards comprising:
- a) a deck for supporting a plurality of boards, the deck having an upstream end and downstream end;
- b) a horizontal displacement system operatively connected to the upstream end for applying a downstream force to the plurality of boards, the horizontal displacement system operable between a disengaged position allowing a new board to be positioned adjacent the upstream end and an engaged position where the plurality of boards is advanced towards the downstream end;
- c) a braking system operatively connected to the downstream end for retarding advancement of the plurality of boards along the deck when the downstream force is below a threshold pressure and for allowing advancement of the plurality of boards if the downstream force exceeds the threshold pressure, the braking system including an upstream pressure system for applying pressure in the upstream direction to the plurality of boards when the horizontal displacement system is moving from the engaged position to the disengaged position;
- and,
- d) a one-way clamping system operatively connected to the deck for opposing the pressure applied by the upstream pressure system, thereby preventing upstream movement of the plurality of boards when the horizontal displacement system is moving from the engaged position to the disengaged position.
A system for maintaining a high inter-joint pressure across a plurality of glued boards being continuously assembled on a deck, comprising a downstream pressure system for advancing the glued boards across the deck and for preloading the energy required for the upstream pressure system, a braking system downstream of the downstream pressure system, an upstream pressure system integral with the braking system for applying a force in the upstream direction to the glued boards, and a one-way clamping system operatively connected to the deck for opposing the upstream force of the upstream pressure system when the downstream presure system is disengaged from the glued boards.
