The invention provides a beam-splitting compound
spinning method for ring
spinning, which includes the steps: feeding with two roves, dividing the feeding roves into several strands of
fiber bundles on the front tongs mouth output point, after being drafted by the conventional
spinning frame drafting mechanism, rotating and twisting the divided
fiber bundle surround the center of rotation into one-ply
yarn, and twisting two one-ply yarns into completed product
yarn. The device includes a separating plate for separating two feeding roves and a separating wheel component for dividing roves into
fiber bundles; a separating plate is fixed on the back roller base, and the separating wheel component is fixed on the vehicle panel and includes a separating wheel shaft, a separating wheel and a transmission friction wheel. The separating wheel is equipped correspondingly to the front leather roller zone, and annular deep-and-swallow, wide-and-narrow separating grooves and a groove perpendicular to the separating groove are equipped on the surface, and the bottom of the groove is parallel to the bottom of the separating groove; The transmission friction wheel is attached to the friction wheel of the front roller. The invention has the advantages that the rove fiber strand has twice beam-splits, three times twistings, the fibre in the
yarn transferred multitimes, which reduces hair
feather, improves
yarn strength and antifriction performance.
