Definitions

  • a carriage supporting a brush is moved along the spindle rail, and the brush severs and removes the underwinding from the base portions of the spindles.
  • a brush is moved along the spindle rail and engages successive base portions of the cop tube for severing the lower thread ends.
  • the base portions of the cop tubes are preferably constructed as metal rings so that the cops are not damaged by the stiff brush.
  • the carrier of the brush is positioned on a guide rail of the spinning machine which is generally provided for a socalled tube carriage, and extends parallel to the spindle rail.
  • the carrier is manually moved along the guide rail.
  • the carrier has means for detachably supporting a brush means which is resiliently mounted and can be pressed against the cylindrical base portions of the spindles for severing and removing the u-nderwindings.
  • the brush is particularly effective if the surface of the base portion is roughened and knurled.
  • the spindles rotate during the removal and cleaning of the underwindings, and the carrier with the brush is moved in a direction opposite to the direction of rotation of the spindles.
  • the brush preferably consists of a plurality of tufts consisting of needles, and the tufts are separated from each other in the direction of the guide and spindle rails.
  • the needles of the brush are curved and hook- 3,426,518 Patented Feb. 11, 1969 like and have free ends bent in the direction of movement.

  • FIG. 6 is a fragmentary perspective view illustrating another embodiment of the invention.
  • FIG. 7 is an elevation, partially in section, illustrating the embodiment of FIG. 6.
  • FIGURE 1 the spindles driven by spindle tapes 12 are positioned in the usual way in a spindle rail 11.
  • a yarn ripping or cutting ring 13 is provided on each spindle.
  • the usual guide rail 15 is positioned in front of the spindle rail, said rail 15 acting as a guide for the so-called tube carriage, here, however, also operating as a guide for the apparatus of the inventor.
  • Said rail 14 is bolted onto the spindle rail by spacing means.
  • the carrier 16 is, see FIGURES 2 and 3, in its basic form a metal plate bent over and having a perpendicular portion 16a and a vertical portion 16b. Said vertical portion 16b carries at its top end a portion 16c that is bent over at its both ends. In said vertical portion 16b a brush-like member 18 is adjustable vertically e.g. by means of vertical elongated holes 17 (FIGURE 1) and fastened by means of bolts 19'. Said brush-like member 18 will be described separately.
  • Said guiding plate 19 has, as can be seen from FIGURE 2, several bends in such a way that said guiding rail 15 is positioned in a longitudinal guiding groove, said connecting portion 16a of the portion 16a also being used for guiding the rail.
  • the apparatus can be adapted very easily, e.g., by replacing said guiding plate 19 by an element 19 having different dimensions to various rail shapes or rail profiles 15.
  • additional means rollers
  • additional means can be used for improving the guiding means and for decreasing the friction. In practice, however, it has been shown that such additional means generally can be omitted.
  • the brush-like member 18 (see particularly FIGURES 4 and 5) has been formed from a spring plate 22 onto which a brush strip 23 is attached, e.g., by means of rivets or cement.
  • Said brush strip 23 consists of a usual linen rubber weave 24, which carries in a known way a clothing with needles 25.
  • the tufts of needles 25 have intermediate spaces 26.
  • Said needles being constructed as hooks bent into the direction of movement of the apparatus along the rail 15.
  • the ends of the spring plate 22 are curved, so that they form connecting portions 27.
  • Said connecting portions 27 have an elongated hole 28 at each end, said holes being provided to connect said brush-like member in a tensioned position in which it is bulged according to FIGURES 1 and 3 relative to the vertical. portion 16b of the carrier 16, with the aid of bolt and nut connections 19'.
  • the elongated holes 17 and 28 extend perpendicularly to each other, thus a double possibility for adjustment is provided.
  • the bulging of said spring plate 22 can be selected in various degrees. Also the vertical position of said spring plate 22 can be adjusted with regard to the carrier 16.
  • a handle or the like 29 is provided in the portion 16a.
  • the novel cleaning apparatus is positioned onto the rail 15.
  • the positioning can be carried out by placing the guiding plate 19 at the bottom and the back side of the rail 15 and by swinging upwardly said plate upward as shown by the hand 30 of the operator (FIGURE 1).
  • FIGURE 1 then the apparatus is moved from the left to the right (see arrow 31).
  • the needle or brush tufts 25 press resiliently against the underwinding area on the base portion 14.
  • Said underwinding area rtates against the direction of the arrow 31, therefore, according to FIGURE 1 in a clock-like fashion (see arrow 32 of the driving spindle tape 12).
  • the tops of the needle or brush tuft 18 resp. 25 are directed to the right in FIG- URE 1.
  • the size of the bolts (FIGURE 3) of the spring plate 22 permits an adaptation to the various operational conditions, e.g., to the various yarn numbers, the various distances of the rail from the spindle rail, etc.
  • the vertical adjustability of the member 22 permits the adaptation to various types of spinning machines.
  • the independent adjustability of the plate 19 and the possibility of replacement by a plate 19 having a different shape by means of the elongated holes 21 also permits an adaptation to different machine types, e.g., different rails.
  • the novel apparatus therefore is suitable to all kinds of spinning machines.
  • the cleaning operation is very reliable. and the time necessary for removing the underwinding threads is greatly reduced.
  • a normal steel plate sometimes a light metal or a light metal alloy plate having the corresponding stability, particularly bending strength, can be used.
  • the member 22 can be made of strip spring steel.
  • the member 19, e.g., can be made of sheet steel having sufficient bending strength.
  • the hook trimming and needle tufts are preferalbly made in the usual way of steel hooks and consist therefore of hardened steel wire.
  • the hook tufts can be ground.
  • a further characteristic of the invention although it does not concern the cleaning apparatus, is the fact that the underwinding areas 14 are resistant to wear and tear.
  • the spindle base portions are hardened steel bodies.
  • the toughening of the underwinding areas 14 is important because of two reasons. The first reason is that the underwinding thread 33 must be wound in a reliable way onto the underwinding area 14 and must not slip. The second reason is that the removal of the underwound threads 33, is carried out much better if the needle brush contacts along a roughened surface, the tops of said hooks or needles projecting into the grooves of the underwinding area. This, however, does not exclude the use of the novel apparatus with smooth surfaces 14, because also in this case an improvement, however small, of the present condition is provided. Also in this case the improvement mostly can be obtained without the usual severing of the underwinding threads by means of sharp brass hooks or by using knives for the same purpose. Said usual measures are particularly detrimental, because the spindle caps can be damaged. Said dangers are avoided by the present measures.
  • the bottom thread ends of each yarn package are cut when still on the cops on the spinning machine, in which said bottom end is clamped between the tube and the spindle during the positioning onto the spindle.
  • the invention also relates to a device for carrying out the method mentioned above.
  • the device can be moved along the spindle rail of the spinning machine, and is provided with a brush means directed to the base portions of the tubes arranged at such a distance from the spindles, that the brush means base portions at the bottom end of the tubes positioned on the spindles.
  • the tube of the cop is provided with a ring of hard material, e.-g., metal, said ring being provided at such a level, that it can cooperate with a brush means when the tube is put onto the spindle.
  • a ring of hard material e.-g., metal
  • the spindle rail 101 of the spinning machine supports spindles 102 which are driven in the usual way.
  • spindles 102 On each spindle 102 there is a cop with tube 103 onto which the yarn package 104 has to be wound.
  • the end 105 of the yarn 106 supplied by the drawing mechanism is clamped between the bottom end of the tube 103 on the spindle 102 between adjacent base portions in order to provide the necessary connection.
  • the yarn package 104 When the yarn package 104 is ready, it must be taken away from the spindle 102. The end 105 of the yarn is freed thereby and then may interlace with the last spun portion of the yarn.
