Title
(EN) PRESS FOR IN-SITU MANUFACTURING A THERMOPLASTIC SANDWICH PANEL
(FR) PRESSE POUR LA FABRICATION IN-SITU D'UN PANNEAU SANDWICH THERMOPLASTIQUE
Abstract
(EN)
A press (10) for manufacturing a sandwich panel comprises a first and second press plate (12; 14) that are movable with respect to one another. The press (10) has a fluid circulation loop for heating and cooling the press plates(12; 14). The fluid circulation loop comprises a heater (22) for generating a hot fluid connected to a fluid supply conduit(24)in fluid communication with an inlet(18) of at least one internal flow channel (16) in each press plate (12; 14) and connected to a fluid return conduit(26) in fluid communication with an outlet (20) of the at least one internal flow channel(16). The fluid circulation loop is also provided with a controlled expansion valve (34) for cooling by conversion of hot pressurized water into steam, and a water source (38) for slow cooling.

L'invention concerne une presse (10) destinée à fabriquer un panneau sandwich comprenant une première et une deuxième plaque machine (12 ; 14), mobiles l'une par rapport à l'autre. La presse (10) selon l'invention comprend une boucle de circulation de fluide destinée à chauffer et refroidir les plaques machine (12 ; 14). La boucle de circulation de fluide comprend un dispositif de chauffage (22) destiné à générer un fluide chaud relié à un conduit d'alimentation en fluide (24), en communication de fluide avec un orifice d'entrée (18) d'au moins un canal d'écoulement interne (16) dans chaque plaque machine (12 ; 14), et relié à un conduit de retour de fluide (26), en communication de fluide avec un orifice de sortie (20) dudit canal d'écoulement interne (16). La boucle de circulation de fluide est également pourvue d'une vanne de détente commandée (34) pour un refroidissement par conversion d'eau chaude sous pression en vapeur, et d'une source d'eau (38) pour un refroidissement lent.
