Abstract
A circular knitting machine includes a pneumatic tensioning duct which receives the article being knitted on the rotating needle cylinder of the machine. 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.
Claims10
In a circular knitting machine, a rotating needle cylinder, a pneumatic tensioning duct along which an air current passes to tension an article being knitted, said duct comprising a rotating portion, a flexible textile net defining a tubular framework in the rotating portion of the tensioning duct, said net framework being deformable between a constricted state whereby it intercepts the article under formation and a relaxed state whereby it permits the knitted article to pass therethrough, and means operable to constrict the framework so that it intercepts the article under formation while the air current is maintained through the framework.
