Abstract
A method and apparatus for blending a 'primary staple' with a 'secondary staple' wherein the weight ratio of the primary staple to the secondary staple is between 10,000:1 and 10:1 is disclosed. The secondary staple is continuously supplied to a blending machine (already working a primary staple) by drafting a textile roving. The drawn roving is then disintegrated into the secondary staple by an air flow amplifier. The air flow amplifier also supplies an air flow to transport the secondary staple to a blending machine, where it is blended into the primary staple.
