Abstract
A press apparatus for curing adhesive on inner adhesion surfaces of substantially continuous wood products (1) under synchronous compression heating. The apparatus includes at least two presses (2) having a mutual distance from each other fulfilling the precondition: L/(n−1), where L is the working length of each press and n is the number of presses in series.
Claims15
A press apparatus for curing adhesive on inner adhesion surfaces of substantially continuous wood products (1) under synchronous compression heating, comprising:
- at least three presses (2) located in series, each said press including a pair of press plates that act against each other and provide a product opening between the pair of press plates, the press plates configured to compress a substantially continuous wood product located in the product opening, each press having a working length, through which series of presses the substantially continuous wood product passes,
- wherein the at least three presses (2) have a mutual distance from each other of L/(n−1), where n is the number of presses in series and L is the working length of each press, and
- a controller configured to control each of the presses in the series such that, with operating parameters of each press being held constant during operation, when conveying the substantially continuous product forward a working measure from i) a first press to a next, second press in the series, and ii) from the second press to a next, third press in series, each section of the product will spend a same first total amount of time in the presses and a same second total amount of time between the presses.
