Definitions

  • the present invention relates to a novel and improved needle bed for needles adapted for the manufacture of knitted fabrics.
  • a principal object of the invention is to provide a needle bed which permits a relatively easy and economic construction and further to replace in a simple manner parts, which are subjected to heavy wear.
  • Figure 1 is a perspective view partly in section of the needle bed according to a first embodiment
  • Figure 2 is a sectioned elevation along the needle channel according to Figure 1;
  • Figure 3 is a perspective view of needle channel serving to guide the needle
  • Figure 4 is a filling strip
  • Figure 5 is a modified form of attachment for the needle channel in sectional elevation
  • Figure 6 is a perspective view partly in section of a modified form of the needle bed
  • Figure 7 is a perspective sectional view along a needle channel according to Figure 6;
  • Figure 8 is a front view after Figure 7 partly in section;
  • Figure 9 is a ground view of the connecting bar common to both embodiments.
  • the numeral 1 designates the base plate on which three flat holding rails 2, 3 and 4 extending parallel to each other are mounted.
  • Each of the holding rails 2-4 has an upstanding marginal row of teeth 5 formed by punching.
  • profiled rails 6 of channel cross-section and having walls of uniform thickness are arranged, each of these channels serving to guide one slidable needle 7, having a tongue 8 and a foot 9, which latter is provided for engagement with a cam-box (not shown) in a known manner.
  • Similar recessed portions 13 and 14 are arranged at the upper rims of the filling strips 10.
  • upper rails 15 and 16 are inserted nited States Patent 0 and having enlarged end portions.
  • Patented June 5, 1956 which extend parallel to the holding rails 2-4 and press the needle channels 6 and the filling strips 10 down on the holding rails, while acting as stops for the said parts.
  • Both of the upper rails 15 and 16, which at the same time may serve to guide the cam-box are connected to the plate 1 by means of sheet metal clamps 17 spaced apart on the lower shank of each upper rail.
  • the two downwards pointing shanks of each clamp 17 which are arranged each between two adjacent needle channels extend through slots in the holding rails 2 and'4 and tensioning bars 18 arranged below the base plate 1.
  • Both shanks of the clamp 17 coact with the tensioning bar 18, which holds a clamping screw 19 acting on the base plate 1 as will be described in connection with Figure 8 in a more detailed manner.
  • the pitch of the toothing 5 at the holding rails 2-4 is chosen according to the desired distance between the needle channels, when manufacturing the needle bed as will be readily understood.
  • the second embodiment is insofar different from the described one that the front end part of the needle channels lying in the working zone of the sliding needles 7 is constituted by a non-metallic end piece 21, which preferably consists of synthetic material, e. g. plastic.
  • This end piece which has channels 21a serving to guide the needles 7 abuts against the needle channels 6 and is seated in a lower part 1a of the base plate 1.
  • the end piece 21 has longitudinal and transverse ribs and besides is provided with a number of eyes 22 each having a cast-in screw bolt 23, which serves to rigidly connect the end piece 21 with the part 1a of the base plate 1.
  • clamps 17 are provided as described in the first embodiment.
  • both shanks of a clamp 17 extend between two adjacent needle channels 6, the lower end of both shanks being received in slits 18a arranged in the tensioning bar These serve to facilitate the engagement and disengagement between clamp 17 and bar 18 as will be readily appreciated.
  • the edges of the needle channels at the free end of the end piece 21 are taken off or rounded. This can be done more easily with the material provided for the end piece 21 than with sheet metal and has the advantage that the yarn can not get caught at the piece 21, that no threads are worn off and that the fabric is not soiled, which danger exists when the fabric is in sliding contact with the metal.
  • the parts of the needle bed according to the described embodiments can very easily be assembled and if necessary removed for replacement.
  • a plurality of holding rails having each a row of teeth 5 provided for the fixation of the needle channels only one such holding rail may be used, it would also be possible to provide one or several rows of teeth directly at the base plate 1, or the latter could be provided with one or several rows of openings to take up one or several rows of teeth formed by tongues at the set of needle channels 6.
