Title (EN) PROCESS AND PLANT FOR MANUFACTURING COMPOUND FABRICS,WELD-ABLE BY HIGH FREQUENCY,CONTAINING SOME PLASTIC MATERIALS,PREFERABLY IN THE FORM OF PARTICLES,AND THE PRODUCTS OBTAINED ACCORDING TO THE PROCESS
(FR) PROCEDE ET INSTALLATION POUR LA FABRICATION D"ETOFFES COMPOUND, SOUDABLES PAR HAUTE FREQUENCE, CONTENANT CERTAINES MATIERES PLASTIQUES, DE PREFERENCE SOUS FORME DE PARTICULES, AINSI QUE LES PRODUITS OBTENUS SELON LE PROCEDE
Abstract:
(EN) Manufacture of textile compound fabrics from elements (30, 31) capable of being interconnected by H.F. welding. The welding is enhanced by addition of plastic materials (5, 51, 52). These plastic materials are resistant to washing agents, cleaning agents, adhesives and have, under the action of a H.F. field, a polar as well as a substantially non-polar behaviour. The elements susceptible to receive the means enhancing the welding may and have to be modified as regards the shape, sections, arranged into a layer with respect to each other and subject to overpressures, to depressions, as well as to other physical, mechanical, chemical, pneumatic, hydraulic, electric and electronic actions, all of this being achieved in machines (I, II, 11, 12, 13, 14) specially designed for this purpose. The products obtained differ from those that are known by the presence in good order within said obtained products of bonding elements made from plastic material particles having a varied dielectric behaviour when they are subjected to an H.F. field.
(FR) Production d"etoffes compound textiles a partir d"elements (30, 31) susceptibles d"etre lies entre eux par soudage HF. Le soudage est favorise par l"adjonction de matieres plastiques (5, 51, 52). Ces dernieres resistent aux agents de lavage, de nettoyage et adhesifs et font preuve sous l"action d"un champ HF d"un comportement aussi bien polaire que pratiquement apolaire. Les elements susceptibles de recevoir les moyens favorisant le soudage peuvent et doivent etre modifies quant a la forme, profiles, disposes en couche les uns par rapport aux autres et soumis a des surpressions, a des depressions de meme qu"a d"autres actions physiques, mecaniques, chimiques, pneumatiques, hydrauliques, electriques et electroniques, tout ceci dans des machines (1, 11, 11, 12, 13, 14) specialement concues dans ce but. Les produits obtenus se differencient de ceux connus par la presence ordonnee en eux d"elements de liaison realises a partir de particules de matieres plastiques faisant preuve d"un comportement dielectrique varie lorsqu"elles sont soumises a un champ HF.
