Abstract
This invention is directed to an improved method for producing quality hosiery in circular knitting machines by changing the stitch length. The density of the knitted hose is regulated by measuring the axial advancement of a tensioning device. This produces hose portion by portion and consequently varies the level difference between the sinker knock-down plane and the minimum level reached by the active needles.
