Definitions

  • the warp threads are reeded by semi-automatic or fully automatic reeding machines.
  • reeding is meant the drawing of the warp threads between the teeth of the reed, which latter, during the weaving operation, is reciprocated longitudinally of the warp threads to push the weft threads into position.
  • These reeding machines comprise drawing elements, such as the so-called passettes or healds, which penetrate between the individual teeth of the reed and control the progress of reeding from tooth to tooth in a known manner.
  • drawing elements such as the so-called passettes or healds
  • healds which penetrate between the individual teeth of the reed and control the progress of reeding from tooth to tooth in a known manner.
  • the healds between the reed teeth
  • Due to this friction the edges of the reed teeth become roughened at their points of contact with the healds. This roughening is very undesirable because the reed, during the weaving operation, is substantially continuously in motion and the Warp threads must slide uninterruptedly between the reed teeth. It the teeth become roughened, they may damage the warp threads, especially if these consist of synthetic fibres.
  • An object of the present invention is to provide a device for reeding warp threads in which such roughening of the edges of the reed teeth is avoided.
  • Another object of the invention is to provide an improved device for reeding warp threads in advance of weaving.
  • a further object of the invention is to provide a device for reeding warp threads including means for lubricating at least one of the warp thread drawing elements, such as passettes or healds.
  • Yet another object of the invention is to provide a device for reeding warp threads wherein, in advance of penetrating between the teeth, at least one of the warp thread drawing elements slides past a lubricant dispensing member to take up traces of lubricant.
  • Still another object of the invention is to provide a device for reeding warped threads wherein anoil-impregnated wick is arranged as a lubricant dispensing member for engagement with a warp thread drawing element as the latter moves toward a position penetrating between the reed teeth.
  • An ancillary object of the invention is to provide such a lubricant dispensing member including an oil-impregnated wick and wherein the lubricant may be replenished.
  • Another ancillary object of the invention is to provide a device for reeding warp threads of the type just mentioned, and wherein the supply container for the lubricant is in the form of a grease box.
  • roughening of the edges of reed teeth by contact with the warp thread drawing elements is obviated by providing means dispensing a lubricant and so arranged that at least one of the drawing elements which come into contact with the reed teeth slides past a lubricant dispensing member in advance of such penetration and, in sliding past this member, takes up traces of lubricant.
  • the single figure is a part schematic and part sectional view of a device for reeding warp threads 1n accordance with the invention.
  • the side surface 21 of the upper heald 2 is biased against the tooth edge 51 so that there is friction between the side surface of the heald and the tooth edge. If this friction occurs as dry friction, edge 51 of the reed tooth may become roughened and the warp thread may be damaged at this point in the subsequent weaving operation.
  • a holder 7 supporting a lubricating pad 8 is mounted 011 a support 6 which is secured at a suitable position on the reeding machine.
  • the lubricating pad may be, for example, a wick impregnated with a lubricant, which lubricant may be replenished.
  • the lubricating pad 8 is so situated relative to the upper heald 2 that the surface 21 of this heald slides over the pad or wick 8 before penetrating between two reed teeth 5', 5". In so doing, the upper heald 2 takes up traces of lubricant.
  • a further lubricative dispensing arrangement such as provided for the upper heald 2 may be operatively associated with the lower heald 4 in such a way that the latter may take up lubricant as it passes over the lubricant containing member in its movement toward the reed.
  • the holder 7 may be, for example, a grease cup or other form of lubricant reservoir.
  • a reeding machine for reeding warp threads preparatory to weaving and of the type including a reed having spaced teeth and a drawing element, such as a heald, for penetrating between the teeth to reed the warp threads, the heald, during such penetration, having frictional contact with the reed teeth: the improvement comprising lubricant means in the path of movement of the heald toward the reed effective to cont act the heald surface to lubricate the same.
  • a reeding machine for reeding warp threads preparatory to weaving and of the type including a reed having spaced teeth and a drawing element, such as a heald, for penetrating between the teeth to reed the warp threads, the heald, during such penetration, having frictional contact with the reed teeth: the improvement comprising a lubricant dispensing member positioned in the path of 5 movement of the heald toward the reed and effective to contact the heald surface to lubricate the same.
  • a reeding machine for reeding warp threads preparatory to weaving and of the type including a reed having spaced teeth and a drawing element, such as a heald, for penetrating between the teethto reed the warp threads, the heald, during such penetration, having frictional contact with the reed teeth: the improvement comprising a lubricant impregnated element positioned in the path of movement of the heald toward the reed and eflective to contact the surface of the heald to lubricate the same.
