  • the invention eliminates the shortcomings of the known devices by forming a needle strip also known as faller bar or gill bar, for affixing needles, such as combing needles, to the needle holders or bars for use in shanks having a thickness corresponding to the desired needle point spacing into close contiguous juxtaposition and in then bonding them together with a bonding agent, such as solder.
  • a needle strip also known as faller bar or gill bar
  • affixing needles such as combing needles
  • the bonding agent does not have to fill gaps between adjacent needles as heretofore necessary, as such gaps are not present, there is a consequent saving of bonding agent, such as solder, it is also possible to utilize the layer of the bonding agent which extends continuously across the entire width of all the shanks of the needles for attaching the assembly of needles to the needle holders or bars.
  • the needle strip is formed of needles having shanks with a circular cross section
  • the needles are chosen so that the shank diameters are equal to the desired needle point spacing.
  • round section needles may be partly flattened to define the width required to provide the desired needle point spacing.
  • the needles can be bonded together with any suitable bonding agent, preferably solder, but if desired, a plastics adhesive could also be used.
  • the needle strip as formed by the shanks of the needles may be covered with at least one reinforcing cover strip.
  • the shanks of the needles are confined combing machines and the like, by placing needles with between two cover strips. This form of construction protects the row of needles against damage during transport and facilitates their affixation to the needle holder or needle bar.
  • the two cover strips may consist of one piece forming the sides of a U-shaped carrier bar.
  • cover strips may be externally smooth
  • two smooth surfaces can be bonded together when the strip of needles is affixed to the needle holder or needle bar, for instance by soldering or by means of a suitable adhesive, such as a synthetic plastics adhesive.
  • a suitable adhesive such as a synthetic plastics adhesive.
  • This not only facilitates affixation of the strip of needles to the needle holder, but it also has the advantage that the contacting surfaces can be provided with accurately metered quantities of adhesive.
  • the arrangement also assists in preventing the adhesive from penetrating between adjacent needles.
  • lateral forces, such as thrusts acting upon the point of a needle cannot dislodge such needle from the bonded assembly because the reinforcing strips absorb the load and keep the needle in position.
  • At least one of the cover strips may be extended in the direction away from the points of the needles. If two cover strips are used it is preferable to extend both strips in such a manner that the two extensions in conjunction conform to the'shape of the needle holder or bar.
  • Such arrangement not only enlarges the adhesion surface-for bonding the strip of needles to the needle holder but it also pemiits attachment of the needle strip to the needle holder by mechanical means, for instance by rivets and bolts, in which case the extensions of the strips may be provided with holes for the rivets and bolts.
  • mechanical afiixation has the additional advantage that an adhesive or solder is not required and that apparatus hitherto needed for connecting the strips of needles to the needle holders, such as soldering equipment, induction or high frequency heating equipment and so forth, can be dispensed with.
  • the arrangement also operates to facilitate repairs, for instance, the replacement of a worn needle strip by a new one.
  • the above described needle strip must, of course, be attached to a needle holder, such as a needle bar in a combing machine. This involves a considerable amount of work and a corresponding expenditure of time and money, particularly since the strips must be replaced at regular relatively short intervals.
  • a further development of the invention obviates this necessity by constructing the carrier strip in such a way that it also constitutes a needle holder or bar which is directly affixable to a combing rail in a combing machine.
  • a suitable structure of this kind is obtained for instance by extending and shaping the cover strips, which sandwich the row of needles between them, so that the extensions themselves form the needle holder or needle bar.
  • the cover strips may be extended to form two connected plates laterally offset from the median plane of the row of needles.
  • the same result can be achieved by providing one cover strip with an intermediate portion extending obliquely downwards and merging into a plate extending downwards parallel to the median plane of the row of needles while the other cover strip is formed with a downwardly arching extension merging into a plate connectable to the first mentioned plate.
  • This form of construction of the carrier strip has the advantage that the row of needles need not be specially affixed to a needle holder or needle bar, and that the time-consuming mounting operation is eliminated. Moreover, the needle bars as were hitherto conventional are no longer necessary and need not be kept in stock.
  • Combers and spinners can be supplied directly by the comb manufacturers with needle holders fitted with the needles in a condition such that they can be directly mounted on the machine.

  • FIG. 15 is a cross section of another embodiment of a strip of needles combined with a needle holder.
  • a continuous needle strip 1 comprises a plurality of round section needles 2 which are placed closely together, that is to say without intervening gaps.
  • the needle point spacing a as required by the comber (not shown) with which the needle strip is to be used, the
  • needles have shanks 3 of a diameter selected in accordance with the required needle point spacing a.
  • the needles are bonded together by a suitable bonding agent, such as a solder, to form the continuous strip 1.
  • a suitable bonding agent such as a solder
  • the diameter b of the shanks of these needles was originally somewhat less than the needle point spacing a but the thickness of the shanks in the crosswise direction has been subsequently increased to the spacing a by squeezing pressure applied to the shanks for producing the flat sides.
  • the strip is composed of flat needles 7.
  • the shanks 8 of these needles have flat contacting faces 9 and the distance between these faces corresponds to the needle point spacing a.
  • the required thickness a in this instance can be obtained by flattening the originally round needles in two stages. In this instance the original needle may have been round with a diameter c (FIG. 9).
  • the bonding agent fonns a layer 4 on one side and a layer 5 on the opposite side. If these layers are sufficiently thick they may be used as the'means for securing the strip of needles to the needle holder or needle bar.
  • At least one reinforcing cover strip 10 may be provided, as illustrated in the embodiments according to FIGS. 10 to 13.
  • two cover strips 10 and 11 are used and bonded to the needles 2 in the region of their shanks.
  • the bonding agent which is used for bonding the shanks of the needles 2 together may be also used for securing the cover strips to the needles.
  • the height of the strips 10 and 11 roughly corresponds to the height of the full diameters of the shanks.
  • each cover strip 10 and 11 may have a downward extension 13 and 14 respectively.
  • one of the strips such as strip 11 is set off to form a shoulder thereby giving it a cross section such that the strips constitute a holder such as a needle bar.
  • the strips 10 and 11 may be made of any suitable material. If heat treatment is required for bending them to form the needle holder they are preferably made of metal.
  • the two strips 10 and 11 are extended to form two plates 15 and 16 which may be sufficiently long and suitably shaped to replace a needle bar.
  • the strip 10 and its plate 15 are made of one piece and coplanar.
  • the other strip 11 and its plate 16 are likewise one piece but are separated by set-off part 17 so that the two juxtapositioned plates 15 and 16 are set-off from the median plane of the needle strip.
  • the needle strip 1 is also formed by the needle shanks and the cover strips 10 and 11.
  • An oblique downward extension 18 of the strip 11 merges into the plate 16.
  • the upper end of strip is joined to a downwardly extending curved portion 19 which merges into the plate 15.
  • the two plates 15 and 16 which form a needle holder, such as a needle bar are laterally set-off from the median center plane of the strip of needles.
  • a needle strip for a combing machine or similar textile machine comprising:
  • a plurality of needles each having a shank portion of uniform and generally round cross-sectional outline along its length and a needle point portion tapered toward its point, said needles being disposed in a single row with the facing surfaces of adjacent shank portions in abutment with each other along the length of said shank portions thereby locating the needles in mutually parallel relationship, the peripheral outline of each of said shank portions being correlated with the spatial location of the respective needle point so that upon placement of the shank portions in said abutting positions all the needle points are automatically located at predetermined distances;
  • a hardened bonding material coating the outwardly facing surfaces of the shank portions and filling the depressions between adjacent shank portions as defined by the cross-sectional outline of the shank portions, said bonding material forming continuous layers on both sides of the row of needles and securing the needles in said mutually parallel relationship, said layers having substantially plane outer surfaces.
