Title (EN) PROCESS FOR MAKING RAISED RELIEF MOTIVES ONTO DRAWINGS PRINTED ON FLEXIBLE THERMOPLASTIC MATERIAL
(FR) PROCEDE POUR LA REALISATION DE MOTIFS EN RELIEF SUR DES DESSINS IMPRIMES SUR MATIERES THERMOPLASTIQUES SOUPLES
Abstract:
(EN) This process is implemented by making a suction through a tube (8) connected to a suction chamber (7) provided in a mould (1) leading to channels or orifices (6) provided on the bottom of the holes (2) intended for the suction of the parts of the printed sheet (11) bearing the motives to be shown in relief, by forming at these locations suction pockets on the printed sheet. Consequently, the mould (1) is compressed and heated simultaneously under high frequency, retaining the sucked sheet between two face plates (12, 13) of a heating press; the plate (13) bears a support sheet (15) on which an element (18) made of a compressible material is placed so that this element will crush under the compression effect by blowing air into the pockets of the printed sheet to increase the relief, and a final product is obtained welded onto the contour of the engraving of the mould and presenting the desired relief.
(FR) Ce procede est mis en oeuvre en realisant une aspiration a travers un conduit (8) communiquant avec une cavite d"aspiration (7) menagee dans un moule (1) aboutissant sur des canaux ou orifices (6) menages au fond des creux (2) du moule destines a aspirer les parties de la feuille imprimee (11) portant les motifs a faire apparaitre en relief, en formant a ces emplacements des poches d"aspiration dans la feuille imprimee et consecutivement on comprime et chauffe simultanement sous haute frequence le moule (1) retenant la feuille aspiree entre deux plateaux (12, 13) d"une presse chauffante, dont le plateau (13) porte une feuille de support (15) sur laquelle on place un element en matiere compressible (18), de facon que cet element s"ecrase sous l"effet de la compression en chassant de l"air dans les poches de la feuille imprimee pour augmenter le relief, et on recueille un produit final soude sur le contour de la gravure du moule et presentant des reliefs desires.
