4 PROCEDE DE FABRICATION DE RESISTANCES ELECTRIQUES ET D»APPAREILS CHAUFFANTS.4 METHOD FOR MANUFACTURING ELECTRIC RESISTORS AND HEATING APPLIANCES.

La présente invention a pour objet un procédé de fabrication de résistances électriques et d'appareils chauffants bon marchés.The present invention relates to a method of manufacturing electrical resistors and inexpensive heating devices.

5 L'invention est caractérisée en ce qu'on dispose, en méandre ou en un autre dessin convenable, sur un support isolant minéral souple un ou plusieurs rubans de fibres de carbone, qu'on recouvre le support ainsi' garni d'un imprégnant minéral ou organique résistant à la chaleur et qu'on calandre le support ainsi traité.5 The invention is characterized in that one has, in meandering or in another suitable design, on a flexible mineral insulating support one or more ribbons of carbon fibers, that the support thus covered is provided with an impregnator mineral or organic heat resistant and calender the support thus treated.

La figure 2 représente une vue d'un support isolant garni d'un ruban de fibres de carbone.embodiment illustrated in the accompanying drawing. FIG. 1 represents a diagram of the process according to the invention. Figure 2 shows a view of an insulating support lined with a carbon fiber ribbon.

A la figure 1, un support isolant minéral souple 1, par exemple du 15 papier de mica ou du papier de paillettes de verre ou du papier constitué en un mélange de paillettes de mica et de paillettes de verre est garni d'un ruban de fibres de carbone 2 préalablement trempé dans un imprégnant adéquat 3 et disposé sur le ruban suivant un dessin choisi au moyen d'un guide 2' mobile. Le support ainsi garni est recouvert * 20 d'imprégnant 4 distribué par un tambour 5 et un râcloir 6. Le produit passe ensuite dans une calandre 7 et est séché et découpé. Il est possible en outre de le recouvrir au moins d'un* côté d'une autre feuille en un isolant minéral souple, de préférence de même constitution que celui ayant servi de support initial.In FIG. 1, a flexible mineral insulating support 1, for example mica paper or glass flake paper or paper made of a mixture of mica flakes and glass flakes is lined with a fiber ribbon carbon 2 previously dipped in a suitable impregnator 3 and placed on the tape in a pattern chosen by means of a movable guide 2 '. The support thus furnished is covered * 20 with impregnator 4 distributed by a drum 5 and a scraper 6. The product then passes through a calender 7 and is dried and cut. It is also possible to cover it at least on one side of another sheet with a flexible mineral insulator, preferably of the same constitution as that which served as initial support.

25 L'imprégnant peut être un imprégnant minéral, par exemple un sel ( alcalin à base de silicate, phosphate, borate, ou borophosphate tel que ' le silicate de potassium ou verre soluble ou un imprégnant organique résistant à la chaleur tel qu'un vernis silicone thermo-durcissable. La * souplesse du produit n'est généralement requise que pendant la 30 fabrication. Le produit final peut être rigide.The impregnator can be a mineral impregnator, for example a salt (alkali based on silicate, phosphate, borate, or borophosphate such as potassium silicate or soluble glass or an organic heat-resistant impregnator such as a varnish Thermosetting silicone. Flexibility of the product is generally only required during manufacture. The final product may be rigid.

La figure 2 montre un exemple d'un support garni d'un ruban en « * fibres de carbone. Les lignes pointillées 9 indiquent comment le produit est ensuite estampé. Il s'agit de résistances destinées à équiper des fers à repasser.Figure 2 shows an example of a support lined with a ribbon of "* carbon fibers. The dotted lines 9 indicate how the product is then stamped. These are resistors intended to equip irons.
