摘要
In a method and apparatus for weaving in which a weft strand is projected in substantially free flight into the warp shed of a loom and is guided across at least a portion of the shed by a plurality of guides, preferably annular in shapes disposed in operative position within the shed in interdigitating with the warp threads, the guides being moved to and fro along an arcuate path for withdrawal to an inoperative position substantially entirely outside the shed and return within the shed and having an opening at a common point thereon to permit the inserted strand to egress therefrom during their withdrawal from the shed, the improvement of (a) engaging the inserted weft strand at spaced points along its length while the strand is within the shed and within the guides and (b) bodily displacing the strand outwardly through such common opening before the guides are withdrawn from said shed. The strand is ordinarily displaced in timed relation to the movement of the guides along their path.
