In order to prevent the article from twisting in the duct during knitting of the article, the article is retained in a rotating portion of the duct by a very flexible tubular grid structure which is located in the rotating portion and which has a constriction to prevent passage of the article. At the end of knitting, the constriction in tubular grid structure is temporarily removed to permit passage of the article.
