    摘要： Method for winding a fibre element (2) onto a support (16), said fibre element comprising at least two longitudinal portions (P i ) with different characteristics, comprising the steps of supplying the fibre element to the support and associating with each longitudinal portion a respective value of the winding pitch (p i ) which is different from the values associated with the portions adjacent thereto; the winding pitch associated with each portion being optionally modulated in accordance with a periodic function.
    A device for carrying out the above method is also disclosed.
    Also a method for distinguishing the different longitudinal portions of the fibre product produced by the above method is disclosed, comprising the steps of unwinding the fibre and detecting the variations in winding pitch. An apparatus for carrying out the latter method is also disclosed.

    摘要： A method and apparatus (10) are provided for forming a fabric (18), suitable for making a finished composite product, using one or more composite strands (16). One embodiment of the apparatus (10) comprises at least one bushing (12) for forming reinforcing fibers (14); supply equipment (60) for supplying matrix fibers (66a); at least one applicator (30) for applying bonding size (i.e., bonding chemical treatment) to the fibers; a gathering mechanism (50) for gathering the treated fibers into at least one composite strand (16); a pulling mechanism (54) for pulling the at least one composite strand (16); and a fabric-forming mechanism (52) for forming a fabric (18) using the at least one composite strand (16). One embodiment of the method comprises the steps of drawing a plurality of reinforcing fibers (14); supplying a plurality of preformed matrix fibers (66a); applying bonding size directly to the reinforcing fibers (14) and the matrix fibers (66a) from one or more applicators (30) at least before the reinforcing fibers (14) are gathered together into a strand (16); gathering the fibers together into at least one composite strand (16); and forming the at least one composite strand (16) into a unidirectional fabric (18). The resulting unidirectional fabric (18) comprises a plurality of stitching threads (19) and a continuous glass/polymer composite strand (16) in the form of a plurality of transverse loops (17). The loops (17) are stitched together by the threads (19). The composite strand (16) can comprise a plurality of first reinforcing fibers (14) drawn from a bushing (12) of molten glass, a plurality of preformed matrix fibers (66a) made from a polymer matrix material, and bonding size which bonds together the fibers of the composite strand (16).

    摘要： The present invention relates to methods and apparatus for winding a plurality of strands (20) into a multilayered package (54). The preferred method includes: a) supplying a plurality of strands (20); b) aligning each of the strands in generally adjacent and coplanar alignment (16); c) oscillating the strands about a pivot axis while maintaining the strands in alignment (22); d) reciprocating a reciprocating device generally parallel to a central axis of rotation of a rotatable packaging collector (54); and e) winding the strands about an arcuate surface (57) of the collector to form a multilayered package, such that within each layer of strands wound upon the surface of the rotatable packaging collector (54), each of the plurality of strands is adjacent to each other and essentially free of overlap. The preferred apparatus includes a strand supply device (12); an alignment device (18); a strand oscillating device (22) including a strand guide (24) adapted to oscillate about a pivot axis and having a first arm and a second arm spaced apart to receive and align the strands; a winding device including a rotatable packaging collector (54) having an arcuate surface (57) adapted to receive the strands to form a multilayered package; and a reciprocating device, such that within each layer of strands wound upon the surface of the rotatable packaging collector (54), each of the plurality of strands is adjacent to each other and essentially free of overlap.

    摘要： A cake of glass fibers or the like has a waste yarn which is provided by winding a strand, which continues from an end yarn extending in contact with a winding tube, on the winding tube to cover the end yarn before a usual winding work for forming a cake on the winding tube. This cake can prevent filaments from being broken by rubbing of the strand in the innermost layer of the cake with the end yarn which is pulled into the cake when the end yarn is cut after the stand is completely wound on the winding tube.

    摘要： Ce bobinoir comporte une broche 2 recevant le fil E à bobiner et un équipage oscillant 6,8,10 portant un guide fil 10 et un palpeur 14. Ce demier est en contact avec le bobinage et commande un élément d'excitation (vanne 20) à fonctionnement continu et agissant sur un dispositif moteur (vérin 27) actionnant l'équipage oscillant. Ainsi, ce demier s'éloigne progressivement et par un mouvement continu de la broche 2 en fonction de la croissance de la bobine. Le palpeur 14 est équilibré autour d'un axe d'oscillation Z-Z pour n'exercer sur la bobine qu'un effort minimal.
    Application au bobinage de fils constitués par des filaments sortant d'une filière de produits verriers.
