ABSTRACT:
A method and apparatus are disclosed for use in the process of treating yarns which includes passing the yarns through a slashing machine (10) and applying a sizing solution to the yarns (20) arranged in side-by-side sheet form, (W), in preparation for weaving on a loom followed by drying the yarns, wherein the apparatus comprises a lease rod (A) for splitting yarns into sheets which includes a porous outer layer (32) and yarn contacting surface (34) having a capacity to sweat a liquid lubricant at a sufficiently precise rate as to control the amount of lubricant wetting the yarn contacting surface. Sticking of sizing material to the yarn contacting surface as occurs with wet yarns coated with concentrated sizing solutions is avoided without weakening the size coatings on the yarns. A source of lubricant is provided (at B) and supply means (C) supplies lubricant from said source (B) in response to the operation and speed of said slashing machine to sweat a proper amount of lubricant onto said yarn contacting surface avoiding overwetting of yarn. Alternately, compressed air may be provided (at B) instead of lubricant and admitted to the interior of the hollow lease rod for blowing off any size coating tending to accumulate on the yarn contacting surface. Sleeve (41) is adjusted over pipe (30) up to the edge of sheets (W1, W2) to expose only that length of porous yarn surface (34) that actually contacts the yarn.
