  • Publication number: 20120122364
    Abstract: A method of forming a circular knit fabric includes feeding a multi-filament non-elastomeric yarn from a first spool into an aperture defined in a yarn carrier plate that guides the non-elastomeric yarn sequentially to a series of knitting needles spaced about a circular needle array; while feeding an elastomeric yarn from a second spool to the yarn carrier plate, such that a fabric is knit to have a ground comprising both the non-elastomeric yarn and the elastomeric yarn. The non-elastomeric yarn and the elastomeric yarn are fed together into the carrier plate aperture in an untwisted, unwrapped relation, such that the fabric ground is knit to have a technical face in which potions of the non-elastomeric yarn are exposed in some areas and portions of the elastomeric yarn are exposed in some areas.

  • Patent number: 5775132
    Abstract: The main object of the invention is to obtain knitwork the density of which is not influenced by the tension of the previously formed loops (15). In the particular case of terry cloth the terries are hence particularly uniform and stable.This is achieved by operationally interposing the terry sinker (2) between two stitch sinkers (3, 21).The method for producing terry knitwork is as follows:the first yarn (12) passes under the stitch hooks (7) while resting on the knocking-over surfaces (8) of the stitch sinkers (3, 21), and then over the terry hook (4) while resting on the terry surface (5) of the terry sinker (2);the second yarn (13) follows the first yarn (12), but instead of passing over the terry hook (4) passes along the working surface (6) of the terry sinker (2).The method for producing wide-mesh knitwork comprises for both yarns (12, 13) a path identical to that of the first yarn (12) of the terry knitwork production method.

  • Patent number: 4592212
    Abstract: A circular knitting machine for the production of cut pile has latch needles (N) in the dial (R) and pile elements (11) in the cylinder (Z). Each pile element has an upper pile forming portion (11a) for example shaped like a hook, and also, spaced substantially therebelow, a cutting edge (11c) which cooperates with an opposed separate cutting edge (12c) of a cutting element (12). Cutting is effected thereby in the direction transverse to the axis of the cylinder (Z). Pile loops (H) are pulled downwardly by the fabric take down (arrow W) from the pile forming portion (11a) to the cutting edge (11c) sufficient time being available, before they are cut, to extend the pile loops (H) as desired and to tension the needle stitches over the just formed pile loops (H). The opposed cutting edge (12c) can be angled or skewed with respect to the cutting edge (11c) so that even with fine gauges, a real scissor action is guaranteed with only point contact of the cutters.
