Abstract:
1. A sewing method, for closing an axial end of a tubular article, comprising the steps of: flattening an end of the article to be sewn by moving close to each other two opposite flaps of said end of the article; inserting said end of the article between two mutually facing laminas that form a passage constituting at least an initial part of a guiding path for said end of the article, so that the article protrudes with a portion of said end from a side of said pair of laminas; producing advancement of the article along said guiding path; performing a first sewing of said end by way of a sewing head arranged proximate to said guiding path while the article advances along said guiding path; disengaging the sewing head from the article and retracting the article along said guiding path until the article returns upstream of the sewing head; again producing advancement of the article along said guiding path; performing a second sewing of said end of the article by way of the same sewing head, while the article advances along said guiding path; disengaging the article from the sewing head.
