A circular knitting machine has a knitting frame, a supporting ring mounted on the machine frame, a needle cylinder supported on the supporting ring. The needle cylinder has a needle cylinder axis and an upper and a lower edge. A carrier shaft is mounted in the machine frame coaxial to the needle axis, a component is mounted on a lower end of the carrier shaft, and a device is provided for moving the needle cylinder relative to the component in the direction of the needle carrier axis so that the needle cylinder can be disassembled or assembled by motions substantially perpendicular to the needle cylinder axis and so that the needle cylinder is movable into an operating position and an assembly position allowing assembly and/or disassembly.

A raw yarn 4 is dyed to a desired color by an ink jet dyeing machine 6, knitted to have a desired texture by a lily yarn machine 10, and fed into a flat knitting machine 20. The height of the needle tips of the lily yarn machine 10 can be changed so that the texture of lily yarn can be modified.

A method for determining the size of the stitch loops in sock-production machines by means of a control unit which stores three pairs of values for each of a plurality of different types of yarns with which each of a plurality of machine zones is to be produced. Each pair of values includes the relative height and the corresponding width of the knitted product, the specific length and corresponding width of the knitted product, and the height of the stitch-formation triangles and corresponding specific length of the knitted product. The width and type of yarn is selected for each zone to be produced, and the relative height corresponding to the selected width and type of yarn for each zone is determined by the control unit by means of an equation which represents a straight line. The rotational speed and angular position of the machine cylinder is measured and fed to the control unit, which then sends signals to step motors. The value for the width stored in the control unit is derived by an autocalibration procedure which utilizes an equation which represents a straight line.

A circular knitting machine has at least one needle carrier, and a plurality of slide needles having a head portion with a head and a slide portion with a tip. Sinkers cooperate with the slide needles, a plurality of knitting systems are arranged along the needle carrier, and a control is provided at the knitting systems for causing relative movements of the needle portions, the slide portions, and the sinkers for performing knitting, tacking and running-through operations. The control includes at each of the knitting systems a sinker cam curve for controlling the sinkers, a slide portion cam curve for controlling the slide portions, and a head portion cam curve for controlling the head portions. The slide portion cam curves have portions for raising and lowering the slide portions in a same manner irrespective of performance of knitting, tucking, or non-knitting operation of the systems.

In a multisystem knitting machine with longitudinally displaceable needles and also displaceable and pivotable sinkers which are alternately positioned in a carrier, an adjusting shaft and an adjusting head for each cam system are positioned on a movable slide on which a plunger of a central adjusting device acts so as to move that slide.

The invention relates to stitch-forming machines, which have needles guided on a needle support means for longitudinal displacement and controlled by needle cams and which also have sinkers displaceable between the needles in the region of their heads, these sinkers having sinker throats and knitting surfaces and being controlled by sinker cams. In order to shorten the distance to be travelled by the needles during drawing of the loops it is suggested that the sinkers be mounted in a plane cam guideway by means of a projecting swivel butt for pivoting movement only and not be displaceable in a longitudinal direction and that the distance from the sinker throats and knitting surfaces to the adjacent edge of the needle support means be alterable solely due to pivoting movement of the sinker.

The invention relates to a device for compensating the differences in thermal expansion of the needle cylinder and sinker ring in a circular knitting machine, with which the sinker ring is supported on projections of webs inserted into axially extending grooves in the needle cylinder. In order to compensate for the differences in thermal expansion, the top region of the needle cylinder is designed to be radially displaceable relative to the sinker ring.
摘要:
A knitting machine comprising a needle bed and a plurality of grooves in the needle bed for receiving knitting needles with a hooked knitting needle positioned in each of the grooves. Each of the knitting needles has an associated plate guided in the same groove. The plate includes a longitudinally extended finger directed toward the hook of the needle. The needle includes a shank portion having a recess therein below the hook of the needle for receiving the finger of the plate with the plate being moveable longitudinally and transversely with respect to the needle for widening a stitch formed therearound.

An apparatus for producing meshware, comprises a needle cylinder carrying a plurality of needles with sinkers therebetween, the needles and the sinkers both being movable so that one part of a stitch is made up by movement of the needles and the remainder of the stitch is made up by movement of the sinkers.The method of producing the meshware is also included.
