ABSTRACT An improved nonwoven-sheet-making apparatus includes an improved rotatable baffle which has a conical section that whose axis is displaced from the axis of rotation of the baffle. In preferred operation, the baffle deflects, spreads and oscillates a fiber stream as it advances from a spinneret to a moving receiver on which the stream fibers are deposited to form a ribbon which is overlapped with like-formed ribbons to form a sheet. The apparatus is particularly useful in making a less ropy more uniform sheet of flash-spun plexifilamentary strands.
