<p>The machine comprises plural forming units each operable to produce two chenille yarns each formed by two binding yarns twisted together to bind short sheared lengths of an "effect" or "fancy" yarn. Each forming unit has, associated therewith, a pair of spindles mounted for rotation about substantially vertical axes and each operable to wind one of the formed chenille yarns thereon. Two pairs of binding yarn supplies are provided for forming each pair of chenille yarns, one pair of binding yarn supplies feeding from above and the other pair of binding yarn supplies feeding from below. Each unit includes a respective motor-driven control shaft in driving relation with the forming unit and with the associated wind-up spindles, and a rotary bell having an axial passage through which an effect yarn is fed formed with two eccentric guide bushes extending therethrough through which yarn is led. A winding and sizing member is mounted beneath each bell member and is formed by two spaced profile portions converging upwardly toward an inverted triangle-shape leg portion and defining respective outwardly facing concave surfaces merging with opposite surfaces of the leg portion, the profile portions defining a slot therebetween extending into the leg portion. A shearing blade disposed symmetrically in the slot between the profile portions shears the turns of effect yarn to form the sheared lengths thereof. A feed roller is engaged with each concave surface to entrain a respective half of the sheared turns of effect yarn, and one of the two upper binding yarns is fed between each feed roller and the adjacent concave surface. Each profiled portion has a hole therethrough and the two lower binding yarns are fed through these holes.</p> |
