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 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.
Claims7
A method of maintaining a high inter-joint pressure between a plurality of boards being assembled into a panel or beam comprising the steps of:
- a) advancing a board across a deck by a horizontal displacement system through a clamping system restricting the upstream movement of the board;
- and
- b) restricting the downstream movement of the plurality of boards with a braking system having a threshold pressure, the braking system further providing an upstream pressure against the clamping system.
A method for applying a consistent clamping pressure between a plurality of boards comprising the steps of:
- supporting a plurality of boards on a deck, the deck having an upstream end and downstream end;
- applying a downstream force to the plurality of boards with a horizontal displacement system operatively connected to the upstream end, 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;
- retarding advancement of the plurality of boards along the deck with a braking system operatively connected to the downstream when the downstream force is below a threshold pressure and 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,
- 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 with a one-way clamping system operatively connected to the deck.
