<p>The present invention relates to a circular knitting machine with stitch retention sinkers that comprises a plurality of needles (2), which are accommodated in slots (3) formed in at least one needle supporting element (4) and are controllably movable along the longitudinal extension of the corresponding slot (3) from an extracted position, in which the tip (2a) of the needles (2) protrudes from a longitudinal end of the corresponding slot (3) to engage at least one thread (5) fed by a thread guide (6), to a retracted position, in which the tip of the needles is retracted into the corresponding slot (3) so as to form a loop of knitting (10) with the engaged thread (5), and vice versa. The machine comprises multiple sinkers (11) that are arranged alternately between the needles (2) and are each arranged laterally with respect to a needle (2). The end of each one of the sinkers that is located proximate to the longitudinal end of the corresponding slot (3) from which the tip (2a) of the corresponding needle (2) protrudes to engage the thread (5) is provided with a beak (11a) that is directed towards the bottom of the slot (3). Each sinker is individually oscillatable, by virtue of the action of actuation means (15,16), on a plane that is substantially at right angles to the bottom of the corresponding slot (3) to move its beak from a retention position, in which the beak (11a) engages the knitting (10) formed by the corresponding needle (2), to a release position, in which the beak (11a) is disengaged from the knitting (10), and vice versa. <IMAGE></p> |
