Definitions

  • the present invention relates to a comb for textile machines.
  • the comb is a set of metallic, flat, parallel, equidistant lamellae called teeth.
  • the loom and warp combs are closed by a frame, the sides of which are mostly made of wood or metal.
  • the object of the present invention is to produce a comb which is suitable for mechanical selection. This result was achieved in accordance with the invention by making an open comb in its upper part. And to prevent the different teeth from being able to move towards or away from each other during work, it is provided, in accordance with the invention, that a portion close to the free end of each tooth is produced with an appropriate profile so as to produce a support stop between one tooth and the other.
  • the advantages obtained thanks to the present invention essentially consist in the fact that it is possible to carry in the re-entry of the comb, not only according to the traditional methods, but also by introducing the wires through the open upper side and then by sliding them from up and down along the sides of the teeth; that it is possible to make the selection tooth by tooth mechanically and automatically, by means of a selector which realizes in sequence the lateral spacing of each tooth separately; that a comb according to the invention can easily be transformed into a closed comb, that it is simple to make and very reliable.
  • FIG. 1 shows, in an axonometric view, a lateral portion of a comb according to the invention, above a generic selector device in its two working positions;
  • FIGS. 2A-2B-2C show the detailed view of three possible tooth profiles for the comb of FIG. 1;
  • FIG. 3 shows the front view of the comb of FIG. 1 of the "closed"type;
  • FIG. 4 shows a sectional view along the line CC of FIG. 3.
  • a comb for textile machines comprises a wooden base 1, the upper face of which extend in parallel and in good number the teeth 2, each of which is constituted by a metal strip fixed to the base 1 by its lower end and with the free upper end.
  • each tooth 2 is profiled by stamping according to two transverse cuts 3 of a depth equal to the interval between the teeth and extending over the entire width of the lense and so as to obtain a profile wavy unilaterally to the longitudinal axial plane of the tooth.
  • the same profile is repeated at the same height for alternating teeth and with a height offset between the adjacent teeth, of a height equal to the height of the lowerings themselves 3. Thanks to this conformation, each tooth 2 of the comb is in contact with the adjacent tooth over the entire surface of the two subsides 3 so as to ensure a constant distance between two consecutive teeth, equal to the interval between the teeth.
  • FIG. 2A illustrates a curvilinear profile
  • FIG. 2B illustrates a Greek profit which is identical to that of the comb of FIG. 1
  • FIG. 2C illustrates a cusped profile.
  • the free end of the teeth 2 is advantageously cut obliquely downwards and outwards according to a bevel 21 which is repeated alternately on one side and the other for the adjacent teeth so that at the bevel d a tooth corresponds - in the longitudinal direction of the comb - the solid part 22 of the adjacent tooth.
  • This particular beveling 21 of the free upper end of the teeth 2 of the comb is provided to allow mechanical and automatic spacing to be obtained, tooth by tooth, in order to facilitate the passage of the wires by laying them transversely or straddling the comb. and then dragging them down between one tooth and the other.
  • This mechanical spacing is achievable for example by means of a selector device 4 comprising a shaft 42, movable alternately on itself and intermittently along an axis xx parallel to the longitudinal axis of the comb and placed above the teeth 2, on this shaft being integrally mounted a transverse balance 41 and with the free end directed downward and beveled bilaterally.
  • the pendulum 41 oscillates between two positions, one active one shown in solid lines in FIG. 1 in which the tip is juxtaposed with the solid part 22 of the free end of each tooth 2 and the other inactive (shown in dashes in Fig. 1) in which the tip of the pendulum 41 is juxtaposed with the missing part, that is to say bevelled 21 of the tooth.
