  • the present invention relates to a combing cylinder for a combing machine which is referred to as a J type combing machine.
  • FIGS. 14 are schematic side views illustrating the combing action of a conventional combing cylinder
  • FIGS. and 6 are side views of the principal portions of a combing cylinder of an embodiment according to the present invention.
  • FIG. 7 is a comparative view showing changes in the gauge.
  • FIG. 8 is a schematic side view of a combing cylinder using saw teeth.
  • a combing cylinder for a combing machine is constructed in such a manner that, as shown in FIG. 1, a combing segment 2 consisting of needles 3 or saw teeth wires 4 is arcuately mounted on a base cylinder 1 along a portion of the peripheral surface thereof, the combing segment being attached thereto as an arcuate surface concentric with base cylinder 1 over the tooth tip portion extending from the combing starting point A to the combing endingpoint B in consideration of the rotary motion of the combing cylinder.
  • it is so arranged as to apply a combing action to fibers gripped between a nipper 5 and a cushion plate 6 in conjunction with the reciprocating motion of the nipper and cushion plate.
  • a combing action of a combing segment 2 is influenced by a clearance (gauge S) between the lowermost end 7 of the nipper 5 and needles 3, and such gauge S is relatively narrow (0.3 0.5 mm.) at a position where the combing ending point B of the combing segment 2 and the lowermost end 7 of the nipper 5 come closest to each other, and is determined on the basis of such value.
  • gauge S becomes gradually wider toward the first row of needles, that is, toward the combing starting point A in conjunction with the reciprocating motion of the nipper 5.
  • the portion which exerts a satisfactory and effective combing action on the group of fibers F is the rows of needles which follow the intermediate one on the combing segment 2, and it has been found that the rows of needles in the first half fail to act effectively on the group of fi- 2 bers F because of the larger gauge S between them and the lowermost end 7 (see FIGS. 2 4).
  • a combing segment 2 is mounted on a base cylinder 1 in such a manner that the distance R, between the rotational axis 0 of the base cylinder 1 to the combing starting point A of the combing segment 2 is greater than the distance R from rotational axis 0 to the combing ending point B of combing segment 2.
  • the length of the portion of needles which project outwardly from a needle supporting member is made gradually larger as the combing starting point A is approached from the combing ending point B.
  • the combing segment 2 consists of a base sector 12 and a plurality of needles 11 of the same length mounted on the outer surface of the base sector 12 in side by side relation in a circumferential direction of the combing segment 2.
  • Each of the needles 11 are of the same height.
  • the inner surface of the base sector 12 is formed by an arcuate or cylindrical surface having radius r and having the center of curvature located on rotational axis 0, while the outer surface of the base sector 12 is formed by an arcuate surface having radius r and having the center of curvature located substantially on an extension C of a radial line C interconnecting rotational axis 0 and the combing ending point B.
  • the thickness of the base sector 12 gradually increases from the minimum value H at the combing ending point B to the maximum value H at the combing starting point A.
  • the length of the portion of needles which project outwardly from the needle supporting member has to be varied at every needle supporting member.
  • the base sector 12 of the combing segment 2 can be easily manufactured by casting, and the needles 11 also can be easily manufactured. Therefore, the combing cylinder according to the embodiment of FIG. 6 is easy to manufacture and inexpensive as compared with that of FIG. 5.
  • 8 designates a detaching roller
  • 9 designates a top comb.
  • the thickness of the group of fibers F based on the number of grains of the resulting combed sliver. That is, it should depend on the amount of cotton feed, but in the case of a J type combing machine a difference of the order of l 2 mm. is effective to greatly increase the number of needle points which effectively act on the group of nipped fibers F as compared to a conventional concentrically mounted combing cylinder of this type.
  • invention (2) needles S (in mm.) S (in mm.) S (in mm.)
  • the lower surface of the cushion plate 6 may be recessed in the form of an arc as shown.
  • a base cylinder having central rotational axis
  • a combing segment having a combing starting point and a combing ending point and including a combing segment base sector and a plurality of saw teeth wire pieces of the same radial length mounted on said base sector in side by side relation in a circumferential direction of said combing segment;
  • each of said saw teeth wire pieces having a series of saw teeth of the same height
  • said combing segment base sector having an inner surface formed by an arcuate surface the center of curvature of which is located on said central rotational axis of said base cylinder;
  • said combing segment base sector having an outer surface formed by an arcuate surface the center of curvature of which is located substantially on an extension of a radial line which interconnects said rotational axis and said combing ending point of said combing segment;
  • the distance between said combing starting point of said combing segment and said rotational axis being greater than the distance between said combing ending point and said rotational axis.
