Definitions

  • the invention relates to a circular knitting machine of the type specified in the preamble of claim 1.
  • Known circular knitting machines of this type are distinguished by the fact that, instead of conventional yarns, predominantly or exclusively threads are used for stitch formation, which consist of stretched fiber materials. These fiber materials are stretched immediately before the stitch formation with the aid of drafting systems associated with the knitting systems, to which fly-downs, drawstrings or the like are fed as primary materials. If necessary, these fiber materials between the drafting and the knitting systems can be converted with the help of spinning devices into temporary yarns with real rotations, which enable transport of the sensitive fiber materials even over longer distances and disappear before the loop formation by the false-twist effect again. Therefore, the stitching is done not with the help of conventional yarns, but with the help of threads that have little or no twists.
  • a problem with circular knitting machines of this type is that it due to the processing of Flyerlunten, conveyor belts od. Like. To a strong linting in the knitting systems comes, which od with flying fibers, dirt particles. Like. Is connected. This applies regardless of whether the fiber material consists of pure cotton or any suitable fiber mixture. As a result, especially the drive units used to drive the drafting systems, since they are largely exposed, tend to so fast a contamination that frequent cleaning work must be performed, which interferes with the knitting process. Or it must be provided comparatively elaborate constructions, which complicates necessary operation and maintenance.
