Provided is a knitting method and a knitting mechanism, and a circular knitting machine, in which in jacquard or semi jacquard knitting using a circular knitting machine, welt stitching is avoided so as to prevent the breakage and overlapping of yarns and filaments. According to the present invention, only needles selected for knitting and needles selected for tucking perform stitching, and needles selected for welting are prevented from performing stitching by a deactivation method, and thus the needles selected for welting do not perform stitching, so that the load on old loops can be suppressed, and breakage and overlapping of yarns and filaments can be prevented.

A circular knitting machine for knitwear includes a needle-holding cylinder having longitudinal grooves arranged around a central axis and housing a plurality of needles and a needle-holding ring having radial grooves housing a plurality of holding-down sinkers, wherein each needle is paired with at least one respective adjacent sinker so as to form a needle-sinker assembly. Each needle-sinker assembly includes a pre-selection element paired with the respective needle and comprising a connecting portion aligned with the radial groove and selectively cooperating with the adjacent sinker belonging to the same needle-sinker assembly. Each radial groove has a rear section and a front section, open on the front side towards the central axis; the front section is wider than the rear section. The front section is configured for laterally containing and guiding the connecting portion of the pre-selection element in its movements during the operating cycle of the knitting machine.

A circular textile knitting machine includes a drive chain for each needle inserted in a respective longitudinal groove, located below a respective needle and operatively interposed between the respective needle and actuating cams. The drive chain includes a sub-needle arranged below the needle and engaged with the needle to be axially moved in the respective longitudinal groove together with the needle. The sub-needle includes a movable butt radially movable between an operating position, in which it is extracted to be engaged with respective first paths defined by first actuating cams and cause activation of the needle, and a non-operating position, in which it is retracted to not be engaged with the first paths. A selector is partly located below the sub-needle and partly alongside the sub-needle and is configured for oscillating between an active position, in which it pushes the movable butt into the operating position, and a rest position, in which it allows the movable butt to return into the non-operating position. The selector is axially uncoupled from the sub-needle and from the needle in a manner such that the needle and the sub-needle are never pushed or pulled axially by the selector. A selecting device acts upon command on the selectors so as to cause the passage thereof into the active position.

A circular knitting machine includes a needle-holding cylinder, having longitudinal grooves arranged around a central axis and housing a plurality of needles, and a needle-holding ring having radial grooves housing a plurality of holding-down sinkers, wherein each needle is paired with at least one respective adjacent sinker so as to form a needle-sinker assembly. Each needle-sinker assembly includes a pre-selection element paired with the respective needle and comprising a connecting portion and an activation element comprising an operating portion. The pre-selection element is vertically movable to a pre-selection configuration in which the connecting portion is engaged into a connecting seat defined in the sinker. The activation element is horizontally movable, towards the central axis, until acting upon the pre-selection element, so that the connecting portion causes in its turn a movement of the sinker in the radial groove towards the central axis, thus performing an activation of the sinker.

A loop cutting apparatus for a circular knitting machine which has a circular cylinder including a plurality of knitting needles movable independently includes an upper needle dial located on the circular cylinder and a plurality of yarn cutting needle sets radially centered about the axis of the circular cylinder. Each yarn cutting needle set includes a first cutter needle and a second cutter needle movable against the first cutter needle in a first yarn cutting displacement thereof. The first cutter needle has a yarn holding section leaned by a yarn and collaborated with the two abutting knitting needles at two sides to pick up and draw the yarn to form a pile loop and a first cutter section connected to the yarn holding section. The second cutter needle has a second cutter section staggered against the first cutter section in the first yarn cutting displacement to cut the pile loop.
