Abstract
The invention relates to spliced fiber glass rovings and systems and methods for splicing rovings. In one embodiment, a method for joining fiber glass rovings comprises overlapping a leading end of a first roving with a trailing end of a second roving to create an overlapped region; pneumatically splicing a portion of the overlapped region to form a spliced region; and applying an adhesive to the spliced region. In one embodiment, a spliced fiber glass roving comprises a spliced region comprising a plurality of glass fibers of a leading end of a first roving intertwined with a plurality of glass fibers of a trailing end of a second roving, wherein the spliced region is between about 1 and 20 centimeters long and has a tensile strength between about 50 and 150% of the first roving prior to splicing.
