    Abstract: Apparatus for drafting fibrous textile material in which a drafting system includes at least one three-roll control unit having first and second intermeshing fluted feed rolls and a fluted slip roll adjacent on of the feed rolls and spaced forwardly of the nip of the feed rolls. A first one of the feed rolls is driven positively from a power source to, in turn, rotate the other feed roll solely by the intermeshing relationship of the feed rolls and the textile material passing therebetween whereby the textile material is gripped between and fed by the feed rolls. The slip roll is driven in fixed angular relation to one of the feed rolls, but not to the other, to cause the teeth of the slip roll to register with the grooves between the teeth of said first one of the feed rolls, without gripping the textile material passing therebetween, and thereby to cause the material therebetween to move in an undulating path while a fiber-distributing slip draft thus is applied to the material as it is being pulled therebetween and drafted in its forward course from the nip of the feed rolls.

    Abstract: A method of and apparatus for guiding a group of slivers through a drafting unit while progressively reducing the width of the group in its course through successive drafting zones of the unit to ensure that the fibers along the longitudinal side edges of adjacent slivers are intermingled throughout the width of the web to obviate the formation of feather-edge selvages on the individual slivers and to ensure homogeneity and substantial uniformity of the fibers throughout the width of the web being drafted. Also, evener roll means is provided for varying the rate of feed of the respective slivers entering the unit in accordance with, and to compensate for, variations in density of the slivers.
