Abstract
An oriented continuous strand mat of glass fiber filaments is formed by interleaved layers of generally circular or random loops and elongated elliptical loops having their longitudinal axes positioned in the direction of travel of an endless conveyor upon which the glass fibers are deployed to form a mat useable in a stampable glass fiber reinforced thermoplastic resin sheet having increased tensile strength in the length of the sheet. An elongated deflector plate having a planar deflecting surface whose length is aligned with the direction of conveyor travel, and whose face plane is generally perpendicular thereto receives pulled strands which have passed through an air flow nozzle and forms the strands into the elongated elliptical loops used to make the mat.
