ABSTRACT:
A method and apparatus for weaving with non-cleaned or as-spun thread uses a cleaning or irregularity removing system between the yarn supply and the pick insertion device of the weaving machine. The cleaning system cooperates with the pick insertion device so that substantially continuous weaving can be maintained, and includes a thread joining device so that weft thread supply can be maintained following removal of an irregularity in the weft supply. Removal of an irregularity is carried out by removing the section of weft yarn containing the irregularity.
