Device and method for proof loading wooden boards

A device for proof loading wooden boards, comprising:

• first feed means (3) located at a first segment (5) of a feed path along which the boards (2) are fed parallel with their main direction of extension;
• means (9) for deforming the boards (2) designed to cause the boards (2) to elongate along their main direction of extension;
• the device being characterised in that it also comprises second feed means (4) positioned at a second segment (6) of the feed path which, with reference to the direction of feed of the boards (2), is upstream of the first segment (5), the first and the second feed means (3), (4) being positioned relative to each other in such a way that they can simultaneously act on two different portions of the same wooden board (2) which is being fed along the feed path, and also being characterised in that the deformation means (9) comprise first and second feed means (3), (4) and can apply a longitudinal tractive force on the boards (2) using the first and the second feed means (3), (4).

A method for proof loading wooden boards, comprising:

• a feed operating step in which a wooden board (2) is fed forwards along a feed path;
• a traction step in which, between two different portions of the board (2), a tractive force is applied which extends along the main direction of extension of the board (2);
• the method being characterised in that during the board (2) feed step it is fed forwards parallel with a main direction of extension of the board (2), and also being characterised in that the traction step is carried out simultaneously with the feed step.
