A machine knitting tool and in particular a machine knitting needle has a shank extending in the longitudinal direction. The machine knitting tool has a stitch-forming portion directly adjacently to a front end and a drive portion directly adjacently to a rear end. At least in the drive portion, an underside of the shank does not have any indentations or recesses and extends along a plane. The shank in the drive portion forms at least one rib portion with a rib height, which is at most 1.1 mm. In addition, the shank in the drive portion forms at least one support elevation, which extends in the height direction beyond the rib height of the at least one rib portion and has an elevation height at its point of maximum height.

A knitting machine capable of changing a pile length includes a low-pile sinker and a high-pile sinker, a low-pile selector jack arranged on the rear end side of the low-pile sinker, a high-pile selector jack arranged on the rear end side of the high-pile sinker, an actuator operable to, when a pile yarn and a ground yarn are drawn in by a knitting needle, selectively perform the first control in which the actuator acts on the low-pile selector jack, the second control in which the actuator acts on the high-pile selector jack, and the third control in which the actuator does not act on any of the low-pile and high-pile selector jacks, and a cam operable to push out the selector jack subjected to the action of the actuator and the sinker which is in contact with the selector jack to an area between the knitting needles.

A circular machine for knitting, hosiery or the like, with sinker actuation device, comprising a needle cylinder; the needle cylinder has, on its lateral surface, a plurality of axial grooves, each of which accommodates a needle that can move on command along the corresponding axial groove in order to pick up at least one yarn dispensed at at least one feed or drop and form knitting; the machine also comprises needle actuation cams, which face the lateral surface of the needle cylinder and define paths that are extended around the axis of the needle cylinder and can be engaged by at least one heel of the needles, which protrudes from the lateral surface of the needle cylinder, in order to actuate the movement of the needles along the corresponding axial groove with respect to the needle cylinder as a consequence of the rotation of the needle cylinder about its own axis with respect to the needle actuation cams and the at least one feed.

A circular knitting machine for manufacturing open-work knitted fabric includes a crown arranged around a needle-holding cylinder and having a plurality of radial grooves and a guiding ring operatively associated to the crown. Each of a plurality of knockover sinkers is housed in one of the radial grooves, is radially movable in the respective radial groove and has a pin configured for cooperating with the needles. At least one shaped sinker is placed beside each of the knockover sinkers and is movable with respect to the respective knockover sinker. The shaped sinker has a protrusion offset laterally with respect to the respective knockover sinker and configured for elongating an interstitch, arranging it on an adjacent needle and forming an open work. A selector is operatively coupled with the shaped sinker and is oscillating in a radial plane between a rest position and an operating position, wherein in the operating position the selector acts indirectly upon the shaped sinker so as to deviate the trajectory of the shaped sinker. A selecting actuator faces laterally the crown and can be engaged upon command with the selectors for causing the selectors to switch from the rest position to the operating position.

A textile tool part pair (15) consisting of two textile tool parts (16) and a method of equipping a textile machine with the aid of such a textile tool part pair (15) are disclosed. Each textile tool part (16) extends in a longitudinal direction (L) between a trailing end (21) and a leading end (22). Proceeding from the trailing ends (21) thereof, the textile tool parts (16) extend away from one another and counter to one another as far as the leading end (22). At the trailing ends (21), the two textile tool parts (16) of a common textile tool part pair (15) are interconnected by a predetermined breaking connection (45). The predetermined breaking connection (45) can be manually separated without tools, in particular by bending about a bending axis (A).

A knitting machine may include a sinker configured to move between an open position and a closed position. The knitting machine may have a sinker actuator system having a first configuration and a second configuration. The sinker actuator system, in the first configuration, may be configured to actuate the sinker from the open position toward the closed position. The sinker may be configured to change the sinker actuator system from the first configuration to the second configuration when the sinker receives an input force above a predetermined threshold in the movement from the open position toward the closed position. The sinker actuator system, in the second configuration, may allow the sinker to move away from the closed position toward the open position.
