Assembled Roving

Basalt Continuous Filaments under the name of Basfiber®

General Description:

Assembled Roving is a multi-end continuous roving. The strands of different spinning cakes are gathered into a single strand and wound into a cylindrical package without twist. Assembled roving consists of some strands drawn at the facility for production of continuous basalt fiber and then assembled together at assembling machines. Assembled roving can be produced at the bobbins of internal or external unwinding depending on customer requirements.

  • Nomenclature

    Our nomenclature is based on three letter followed by three numbers split by dot and dashes.
    Example:

    RAS-13.1200-11

    The first letter will be always R which stands for our Rovings products. The following letters AS - GN - DR represent the roving type:

    AS - Assembled Roving: External unwinding bobbin roving with on a tube or Internal unwinding (tubeless).

    GN - Gun Roving: Internal unwinding (tubeless)

    DR - Direct Roving: Direct Unwinding

  • Tex Info

    Tex of assembled roving is determined by:

    • Fiber's monofilament diameter;
    • Number of monofilaments in strand (i.e. number of nozzles in bushing);
    • Number of strands in assembled roving which is limited by number of places at the creel and acceptable level of catenary which is getting worse with increasing of number of strands in assembled roving.

    In our opinion, it is not wisely to use assembled roving which consist of more than 10 strands assembled together. Mechanical tests show 30% difference of tensile strength between assembled rovings consisting of 4 and 20 strands due to increased catenary.
