ABSTRACT:
A fiber strand delivered to a draft zone between a pair of back rollers and a pair of front rollers is introduced into a passage formed through a fiber strand guide device. On the way of the passage, floating fibers contained in the fiber strand are controlled by means of a fluid stream jetted to a back surface of the fiber strand to press the fiber strand onto an inner wall of the passage as well as forward it towards the front rollers. A pressing plate may be cooperatively utilized with the fluid stream. Accordingly regular drafting is attained.
