Abstract: The invention concerns a circular knitting machine for making plush fabric. The circular knitting machine has a needle cylinder fitted with knitting needles, a sinker ring fitted with sinkers, wherein the sinkers have edges adapted to handle a ground yarn and a plush yarn, and at least one knitting system. For independent adjustment to the stitch size and the plush yarn loops, a cylinder cam section has an adjustable cam part which serves to adjust the length of the plush yarn loops. A cam part independent therefrom and also adjustable serves to adjust the stitch size. This cam part can be arranged either in the sinker cam or the cylinder cam.

Abstract: For the production of plush knitted goods containing stitches made from main and plush threads, main threads and plush threads are fed to hooks and sinkers, at least the plush threads are pre-formed to plush thread loops by drawing back the knitting tools from a plush thread receiving position into an intermediate position and by, in so doing, drawing and holding taut the plush threads over associated ones of the sinkers, then stitches are formed with the main threads and plush thread loops by drawing back the knitting tools farther into a knocking-over position and by, in doing so, controlling the sinkers in such a way that the pre-formed plush thread loops are held in taut during the stitch formation and that the risk of shortening or undoing of pre-formed plush thread loops during such stitch formation is greatly diminished.

Abstract: The switching device is designed for switching on or off an electrical switching element assigned control to at least one functional unit of a knitting machine, including a timing generator and a pattern controlling device delivering binary control signals used for the selection or the non-selection of knitting needles according to a desired pattern. The switching device includes an electrical switching circuit having a first input connected to a pattern controlling device and an output connected to the electrical switching member, and further includes a device which, at the output, produces a switching, on or off signal when the input receives a predetermined sequence of the binary control signals of the same binary value, or when, after the predetermined sequence, there occurs a control signal of the other binary value or when this other conrol signal of the other binary value occurs after a predetermined time delay.

Abstract: The knitting machine has knitting elements including needles, sinkers, and the like and guide parts for the knitting elements, including cam parts, guide tricks and the like, these groups of parts moving relative to each other and being provided with mutually contacting sliding surfaces or faces. To reduce heating during operation, the need for auxiliary lubricating devices, and to lower power requirements during operation the opposing sliding surface or faces of the moving parts of the knitting machine are at least partially provided with a friction-reducing and wear-resistant coating of diamond-like carbon. This coating is applied by a plasma CVD process (FIG. 3).

Abstract: The invention relates to a circular knitting machine and a method carried out thereon for kniting patterned knitwear with a plurality of yarns. So that it is also possible to make patterns in which any yarns (25) are not worked by a plurality of adjacent needles (12), the floats (26) resulting therefrom are parted from inside the needle circle (10a) and the yarn ends (28) thereby resulting on the side of the associated yarn guide (24) are constantly retained in the capture region of the needles (12) selectable by the selector device for yarn reception. The patterning can thus be effected solely with the aid of the selector devices. Yarn change devices or ring guide bars are not needed (FIG. 2).

Abstract: 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.
