Description

Procede de fabrication d'un tube en Papier impregne de resine synthetique et arme, et tube obtenu par ce procede. 0n eonnait de nombreux emplois des tubes en Papier impregne de resine synthe- tique, obtenus par enroulement, autour d'un manehon, dune feuille de Papier, prealable- ment impregnee de resine synthetique, Pas sage au four et retrait ensuite du manchon; Ges tubes sont legers et parfaitement cylin- driques, mais ils ne presentent pas, malheu- reusement, pour des emplois mecaniques, des qualites de rigidite et de resistance suffi- sante. Process for manufacturing a paper tube impregnated with synthetic resin and reinforced, and tube obtained by this process. Many uses were known of paper tubes impregnated with synthetic resin, obtained by winding around a sleeve a sheet of paper, previously impregnated with synthetic resin, passing through the oven and then removing the sleeve; These tubes are light and perfectly cylindrical, but they do not, unfortunately, have qualities of rigidity and sufficient resistance for mechanical uses.

La presente invention comprend un pro- e6d6 de fabrication d'un tube en Papier im- prAgn6 de resine sy nthetique et arme, caracte- rise en ce qu'on incorpore, au cours de 1'en- roulement de la feuille de Papier, une feuille metallique tres mince. The present invention comprises a process for the manufacture of a paper tube impregnated with synthetic resin and reinforced, characterized in that, during the rolling up of the sheet of paper, a very thin sheet of metal.

Elle comprend en outre un tube obtenu au moyen de ce procede. It further comprises a tube obtained by means of this process.

Au moy en dune mise en oeuv re particu- liere du procede, 1e tube est constitue par une feuille de Papier impregne de resine synthe- tique enroulee d'abord sur elle-meme, puis avec interposition, entre les differentes eouches de ladite feudle, dune autre feuille tres mince, en acier par exemple, dont 1'en- roulement peut debuter apres 1e commence- ment de 1'enroulement du Papier et cesser avant la fin de son enroulement, de fa@on ä benefieier integralement de la teehnique et de la presentation dun cy lindre de Papier impregne de resine synthetique aussi r6gu- lier que possible. By means of a particular implementation of the process, the tube is constituted by a sheet of paper impregnated with synthetic resin rolled up first on itself, then with interposition, between the different layers of the said felt, another very thin sheet, in steel for example, the winding of which can begin after the beginning of the winding of the Paper and stop before the end of its winding, so as to fully benefit from the technique and presentation of a cylinder of paper impregnated with synthetic resin as regular as possible.

11 est possible, bien entendu, d'obtenir la rigidite, la resistance et 1e poids voulus par dosage de 1'element incorpore: celui-ei peut, d'ailleurs, Atre autre que de 1'acier, de 1'alu- minium par exemple, et sa quantite et sa na- ture sont fonction des qualites particulieres desirees pour 1e cylindre. It is possible, of course, to obtain the desired rigidity, resistance and weight by dosing the incorporated element: this can, moreover, be other than steel, aluminum for example, and its quantity and nature depend on the particular qualities desired for the cylinder.

L'element incorpore peut, enfin, Atre cons- titue par une Bande continue ou diseontinue aussi bien Jans 1e sens longitudinal que dans 1e sens transversal; il peut aussi etre dispose en heliee, Atre croise ou autrement. The incorporated element may, finally, be constituted by a continuous or discontinuous band both in the longitudinal direction and in the transverse direction; it can also be arranged in a helix, cross shaft or otherwise.

0n realise ainsi des cy lindres qui presen- tent une resistance ä la flexion bien supe- rieure ä Gelle d'un cvlindre en Papier im pr6gne de resine synthetique, elassique de meme epaisseur, tout en eonservant 1'avan- tage de presenter exterieurement toutes les qualites du Papier impregne de resine syn- thetique, qualites appr eciees notamment pour la manipulation des textiles artificiels. Cylinders are thus produced which have a resistance to bending much greater than that of a cylinder made of paper impregnated with synthetic resin, elastic of the same thickness, while retaining the advantage of presenting externally all the qualities of paper impregnated with synthetic resin, qualities particularly appreciated for the handling of artificial textiles.

C'est ainsi que peuvent etre- conatituees des ensouples RTI ID="0001.0269" WI="8" HE="4" LX="1330" LY="2151"> pour metiers ä tisser et sur- tout des ensouples pour ourdissoirs ä Brande vitesse qui necessitent 1'emploi de cylindres parfaitement equilibres. This is how RTI beams ID="0001.0269" WI="8" HE="4" LX="1330" LY="2151"> for weaving looms and above all beams for warping machines can be made. at high speeds which require the use of perfectly balanced cylinders.
