  • Process and device for manufacturing a composite strand
    Patent number: 8470218
    Abstract: The invention relates to a process and a device for manufacturing a composite strand formed by combining continuous glass filaments with continuous high-shrinkage organic thermoplastic filaments.
    Type: Grant
    Filed: March 23, 2007
    Date of Patent: June 25, 2013
    Assignee: OCV Intellectual Capital, LLC

  • Method for the production of glass threads coated with a thermofusible size and products resulting therefrom
    Patent number: 7886562
    Abstract: The present invention relates to a process for producing glass strands coated with a hot-melt size, whereby molten glass streams, flowing out of orifices located in the base of one or more bushings, are drawn in the form of one or more sheets of continuous filaments, the filaments are then assembled into one or more strands that are collected on one or more moving supports, this process consisting in depositing a first composition containing a coupling agent on the glass filaments and then in depositing a second composition comprising a hot-melt polymer in the melt state, at the latest during assembly of the filaments into one or more strands. It also relates to the glass strands obtained according to this process and to the composites containing said strands.

  • Process And Device For Manufacturing A Composite Strand
    Publication number: 20100230851
    Abstract: The invention relates to a process and a device for manufacturing a composite strand formed by combining continuous glass filaments with continuous high-shrinkage organic thermoplastic filaments. According to the invention, the thermoplastic filaments are mingled in the form of a web (10) with a bundle or a web (2) of glass filaments after having been drawn, heated then projected onto a moving support (17) with a speed, during their projection onto the support, greater than the running speed of said support. It also relates to a suitable device for carrying out the aforementioned process.

  • Method and Device for Producing a Composite Yarn
    Publication number: 20080299856
    Abstract: The invention concerns a method for making continuous coextruded intermingled glass filaments and continuous thermoplastic organic filaments that enable non-spinnable compounds to be incorporated at the thermoplastic filaments. The invention is characterized in that the thermoplastic filaments are obtained by coextrusion of a thermoplastic material acting as core and a thermoplastic material containing at least one non-spinnable compound. The invention also concerns a device for implementing the method. The resulting composite yarn is provided with specific core properties provided by the non-spinnable compounds.
