We will provide three types of rovings: direct roving, assembled roving, and high-strength assembled roving.
Direct Roving
Direct Roving is a process by which continuous single-ended filaments are drawn parallel to one another, then coated with sizing, are bonded, and wound on bobbins.
​
Typically, direct roving is utilized in weaving, fabrics, or any other form of direct use.
Assembled Roving
Assembled Roving is a process by which several single-ended continuous filaments are joined on a special assembling machine and wound on bobbins.
​
Typically, assembled roving is utilized by those who require a roving with greater linear mass density.
High-Strength Assembled Roving
High-Strength Assembled Roving follows the process for assembled roving but is done so with reduced catenary and resembles direct roving in shape. This roving, like the others, is also wound on bobbins.
Typically, high-strength assembled roving is utilized in the pultrusion process, since it prevents loops forming during assembly while ensuring that all of its high mechanical properties are utilized.
