Patent FR-2289588-A1 (FR)
IPC: B29C65/00
Filed: 1975-11-03
Abstract: A cylindrical strand with a thermoplastic outer shell (e.g., plastic insulated wire) is bonded along its length to a similar or different cylindrical strand by laser heating. The strands are brought into contact with one another at a contact point. A laser beam of selected power and wavelength is directed at the contact point in a direction approximately parallel to the axis of the strands as the strands are carried past this point. Absorption of the light by the plastic causes melting sufficient to produce bonding. The depth of penetration of the thermal energy into the plastic is controlled by selection of the wavelength of the laser radiation relative to the absorption spectrum of the thermoplastic material. The laser power level is adjusted to control the total energy input in accordance with the strand feed rate.

Title: Dispositif regulateur du debit du fil des machines distributrices de fil
IPC: B65H59/10
Filed: 1977-05-13
Abstract: Le dispositif comprend, suivant un mode de réalisation un tambour 5 entraîné en rotation lors de la distribution du fil et tournant fou autour de l'axe XX'. Ce tambour est pourvu d'un grillage fin 6 dans lequel pénètrent les filaments flexibles élastiques d'un élément 7 formant brosse. L'élément 7 est solidaire d'un support 8, solidaire lui-même d'une partie creuse taraudée en 9 dans laquelle pénètre l'axe fixe XX' fileté en 10. Dans ces conditions, lorsque le tambour 5 est entraîné en rotation, il en résulte un effet de friction provoqué par le frottement des filaments flexibles pénétrant dans le grillage fin. Si la vitesse de rotation du tambour 5 dépasse celle qui est requise, l'effet de friction augmente, mais il en résulte aussi un déplacement angulaire du support 8, donc une augmentation de la distance e, diminuant ainsi l'effet de friction. Un ressort antagoniste tend à ramener le support 8 à sa position initiale. Application : machines distributrices de fil, notamment pour la fabrication des bobinages de déviation.
