  • Patent number: 5867880
    Abstract: A method for producing textiles from fibers and/or filaments circulating in the form of a web by performing transverse texturing of the fibers and/or filaments as well as stretching thereof, and collecting the fibers and/or filaments in the form of at least one crinkled pseudo-yarn (100) of a given length in which the fibers and/or filaments are properly parallelized. The method is characterized in that said fibers and/or filaments are collected in or against transfer members (9) separate from the needles and the full length of said pseudo-yarn (100) is transferred to needles (11 or 21) for receiving the pseudo-yarn (100).

  • Patent number: 5239734
    Abstract: The present invention relates to a process for manufacturing a textile product by starting with fibers and/or filaments in which these fibers and/or filaments travel in the form of a web. The technique consists in subjecting the fibers and/or filaments to a transverse looping accompanied by drawing and that the latter are accumulated in the form of loops in which the fibers and/or filaments are parallelised.

  • Patent number: 4675216
    Abstract: A process and apparatus for manufacturing synthetic decorative coverings is presented in which at least one powder (generally a polymeric resin) is selectively deposited, in accordance with a pattern or decoration, onto a base material. The power deposition is carried out under gravity without contact between the means of applying the powder and the base. At least one of the deposited powders contains particles which are fusible at a temperature below the distortion temperature of the base and which is compatible with the base material. At least one thermal treatment is then carried out at a temperature below the distortion temperature of the base so as to fix the decorative pattern produced by deposited powders. The apparatus for applying the powders consists of a continuous screen printing frame, in particular, a screen printing roller which is fed by a device providing uniform distribution of the powder into a hopper located inside the roller.
