Roving is a bundle of continuous filaments combined into a discrete strand and wound into a cylindrical package without twist.
Basalt single-end rovings consist of continuous parallel filaments coated with a sizing, bonded into a single strand (end) without twist and wound into a cylindrical bobbin shape.
The single-end rovings are available in various tex. The bobbins are available for payout from the inside (direct rovings) or the outside. Basalt direct roving produced by directly winding a certain number of individual basalt filaments from the bushing.

Multi-end rovings are assembled continuous rovings produced be assembling 2 or more strands coated with a sizing, bonded without twist and wound into a cylindrical bobbin shape. The assembled rovings are available in various tex. The bobbins are available for payout from the inside or the outside.
