ABSTRACT:
A method for forming a web of weft yarns, which run transversely relative to the length of the web, and which may be incorporated in a non-woven fabric, wherein a pair of laterally spaced substantially parallel helical yarn guide members are each rotated about their own axis and at least two yarn feed elements are rotated about an axis parallel to and between the two laterally spaced helical yarn guide members, the weft yarn being fed through at least two of the yarn feed elements whereby they are wrapped around the laterally spaced helical yarn guide supports. A yarn guide ramp is provided adjacent each helical yarn guide member on the upstream side of the member, with respect to the direction of rotation of the guide element, the yarn guide ramps guiding the yarns as they leave the feed elements so that they are engaged between successive turns of the helical yarn guide members.
