Articles (12) made by winding of filamentary material (11), such as yarn and thread, are especially suitable for providing brushes and pile weatherstripping. In order to enable the yarn (11) to be unwound and payed out of spools (24) disposed in a stationary or static array, the yarn is fed from the spools (24) through a rotating spindle (30). A frame (14) located at the beginning of the path and may be provided by laterally spaced pairs of wire (52) which travel around posts (36) provided by rollers on a stationary bracket (38). In order to support the bracket (38) and the frame (14), a shaft (28) reciprocates a pair of support rods (100, 102) in synchronism with the rotation of the spindle (30). Bindings (60, 62) are applied to the ends of the loops (54) as they leave the winding station (14). Slitters (20) divide the loops (54).
L'invention concerne des articles (12) fabriqués par bobinage d'une matière filamenteuse (11), comme un fil textile, convenant tout particulièrement à la fabrication de brosses et de coupe-froid en poils. Pour permettre à des bobines (24) disposées en réseau fixe ou statique de dérouler et de débiter le fil textile (11), celui-ci passe des bobines (24) à travers une fusée rotative (30). Un cadre (14) placé au début de la trajectoire est formé de paires de fils (52) espacées latéralement passant autour de montants (36) formés par des rouleaux sur un support fixe (38). Pour soutenir le support (38) et le cadre (14), un arbre anime d'un mouvement de va-et-vient une paire de tiges porteuses (100, 102) en synchronisme avec la fusée (30). Des attaches (60, 62) sont appliquées aux extrémités des boucles (54) lorsqu'elles quittent le poste de bobinage (14). Des refendeuses (20) divisent les boucles (54).
