MACHINABLE BLOCK OF WOOD FOR FORMING A TOOL, ITS MANUFACTURING METHOD AND TOOL OBTAINED

摘要

The block (1) has a support zone (3) formed of a layer to a stratum of a panel (4) of a counter plate constituted of a middle sheet, or superposition of two layers formed of the stratum of the panel of the counter plate and other stratum of the panel of the counter plate or wood battens (5). The stratum of the panel of the counter plate is arranged on both sides by delimiting between two air circulation passages (6), and the layers are formed between the air circulation passages by a thermosetting binding. An independent claim is also included for a method for processing a machinable wood-block for constituting a matrix, a punch and a mould.
