Abrégé
(EN)
A press pad is provided for use in a laminate press operating at temperatures of up to 180 °C such as a high pressure laminate press or a veneer or marquetry press. The pad comprises a woven fabric (10) of strands that are heat resistant up to 200 °C and wherein a substantial proportion of at least one of the wrap (11) and the weft (12) comprises silicone covered strands (12). The fabric (10) contains no metal strands and the other (11) of the silicone covered strands (12) comprises at least one of a polyester and a non-aromatic polyamide yarn such as nylon. Preferably, the silicone covered strands (12) comprise a silicone covered glass yarn (13, 14). The weight of such a pad can be made less than one third the weight of a conventional press pad containing a substantial proportion of metal wires, which facilitates the handling and manipulation of large press pads by press operatives. In addtion, it is inexpensive to produce.

Cette invention concerne un coussinet de pression pour presse à stratifiés pouvant fonctionner sous des températures jusqu'à 180 °telles que des presses haute pression pour stratifiés ou des presses pour plaquages ou marqueterie. Le coussinet comprend un tissu (10) fait de fils pouvant résister à des températures de 200° C maximum et dans lequel une partie substantielle de la chaîne (11) et/ou de la trame (12), comprend des fils (12) recouverts de silicone. Le tissu (10) ne renferme pas de fil métallique et la chaîne (11) ou la trame (12) qui renferme des fils recouverts de silicone comprend au moins un fil de polyester et un fil de polyamide non aromatique tel que du nylon. Les fils (12) recouverts de silicone comprennent de préférence un fil de silicone recouvert de verre (13, 14). Le poids d'un tel coussinet s'établit à moins d'un tiers de celui d'un coussinet classique renfermant une proportion importante de fils métalliques, ce qui, pour les opérateurs de presse, facilite la manutention et la manipulation des patins de grande taille. De plus, le patin selon l'invention est peu coûteux à fabriquer.
