ABSTRACT:
A method and apparatus for weaving woven articles in a plurality of widths includes the steps of providing a weaving machine having at least one weaving head and harnesses controllably guiding a multiplicity of warp strands between first and second path planes that converge at the weaving head, a reed member reciprocally moving between the harnesses and the weaving head for packing a weft strand into the woven articles, the reed member having a multiplicity of slots for receiving and guiding the warp threads in planes intersecting the first and second path planes, the slots being closely spaced and defining a maximum weaving width W.sub.M of the weaving head, the woven articles being serially collected from the weaving head; separating the warp strands from the reed member into a first group and a second group, the first group including sufficient warp strands for forming the woven articles at a predetermined weaving width W.sub.1 ; feeding the strands of the first group into the weaving head for forming the woven articles having the predetermined with W.sub.1 ; feeding the strands of the second group in a bypass path bypassing the woven articles; and maintaining a collection tension in the strands of the second group within the bypass path, the collection tension being sufficient for feeding the strands of the second group from the reed member in unison with the strands of the first group.
