Abstract

PURPOSE:To obtain a core yarn of high covering degree and elongation without using a complicated mechanism, by feeding a multifilament yarn to a yarn bundle which is being drafted in a specific state. CONSTITUTION:The multifilament yarn 5, a core yarn, is fed to and laid on the fleece 6, which is being drafted, by the regulating groove 10. Preferably, the yarn 5 of S twist is fed to the somewhat right side of the vertical line of the yarn bundle width regulating part 11; that of Z twist, to the somewhat left side. For example, the yarn 5 is fed under a tension <= 10g, and the collector 1 is made movable following the movement of the fleece 6 freely to prevent the fluffing and not to weaken the drafting effect of the fleece 6. The core yarn 9 having a higher elongation than ever before and a slight peeling can be obtained easily.
