Abstract: Apparatus for guiding an edge portion of an article through a stitching machine has supports for supporting the article and sensor means such as a fluid jet and sensor interrupted by the edge of the cloth. The sensor means provides a sewing guidance signal indicative of the position of the edge of the article to be stitched and means responsive to the sewing guidance signal move one or more of the supports to guide the said edge towards the said predetermined position. Preferably the supports support a tubular article in tubular form. In cases where the edge of a tubular article after the stitching operation is displaced relative to the position the edge had before the stitching operation, there may be included seam detector means arranged to detect the beginning of the stitched edge of the tubular article and to discontinue guidance of the edge.
