    Abstract: The invention relates to a textile bonding composition comprising a salt of lignosulfonate, an aldehyde hardener thereof, and an elastomer latex. The lignosulfonate salt may be sodium, potassium, magnesium, ammonium, or calcium lignosulfonate. The invention also relates to the use of such a composition for imparting adhesion properties to a reinforcement textile, with regard to a rubber, a reinforcement textile, in particular yarn, cord or textile structure, at least partially coated and/or impregnated with this composition, and a part made of rubber or comprising a rubber, in which the rubber comprises at least one reinforcement textile, on the surface and/or integrated inside the rubber.

    Abstract: Said preform (3) defining two parts (21, 23) and comprising: a first group (C1) of layers of warp yarns, which is external in the first part, a second group (C2) of layers of warp yarns immediately beneath said first group, and a first group (T1) of layers of weft yarns which is external in the first part. Furthermore, the first group of layers of warp yarns is absent in the second part and the first group of layers of weft yarns (19) extends into the second part, the first group of layers of weft yarns being external in the second part. The yarns of the first weft group have a lower yarn count than the yarns of the second weft group; and/or the yarns of the first warp group have a lower yarn count than the yarns of the second warp group.

    Abstract: The invention relates to a method and facility for manufacturing a tape of reinforcement filaments impregnated by a polymer matrix, said tape having a constant width across the entire length thereof, wherein the filaments extend in a direction parallel to the length of the tape, from a strand of filaments coming from a feeding reel, the method including steps and units that make it possible to manage the unwinding tension of the strand, to guide the strand on the axis of the machine, to manage the width of the strand, to deposit the polymer on the strand by electrostatic powdering, with a polymer weight ratio of around 20% to around 75% to melt the polymer, to calibrate the width and thickness of the tape and to collect the tape on the storage reel.
