Definitions

  • the invention relates to the batten of a weaving machine comprising a thin-walled hollow body which contains a thin-walled tube and a pair of arms between whose free ends there is a gap for locating the lower stringer of a reed with which the arms are connected by means of bolts into a fixed separable unit.
  • the batten of a weaving machine usually consists of two connected bodies, and more exactly, of a reed and a swinging means on which the reed is mounted and which ensures the reciprocating motion of the reed.
  • a weaving machine especially in highly productive weaving machines, provision must be taken for fixed and rigid connection of the reed with the swinging means, for easy exchangeability of the reed, and for sufficient torsional and flexural rigidity of the batten.
  • the above requirements for fixed and rigid connection of the reed with the swinging means are fulfilled to some extent by situating relatively stiff swords on relatively stiff swinging means.
  • the swords carry a heavy and complicated beam seated therein and fitted with a groove into which there is inserted by its lower stringer the reed fixed by a plurality of screws on the length of the beam by which the reed is at the same time leveled.
  • the beam can serve for instance also for the seating of auxiliary jets, of a confusor, or of the guide path of the weft carrier in the shed.
  • the uniformity of the fixing force exerted on the reed by the system of screws situated along the length of said beam is obtained by means of an additional vee strip inserted into said groove in the beam between one side of the groove and the lower stringer of the reed.
  • Another used arrangement contains a relatively stiff swinging means fitted with a plurality of relatively stiff swords in which the reed is fixed by its lower stringer. If the distance between the individual swords is chosen in such a manner that the deflection of the lower stringer is negligible, the value of the flexural and torsional deformation of the batten depends exclusively on the rigidity of the swinging means which must resist the action of the load in view of the inertia moment of the whole batten. However, the value of the moment of inertia depends chiefly on the distribution of the mass of the batten in relation to the axis of rotation of the batten.
  • the thin-walled hollow body can be made either of a metal alloy with a high relation strength/specific weight, for instance of dural, or it can be made of a composite material.
  • the thin-walled hollow body according to the CZ 278 388 made of a composite has proved to be apt for production only with difficulties and at accordingly high costs with correspondingly unfavourable price of such a thin-walled hollow body.
  • the invention aims to eliminate or at least to reduce the drawbacks of the background art and to achieve a moment of inertia of the batten as low as possible.
  • the aim of the invention has been reached by the batten of the weaving machine whose principle consists in that the arms are by their end opposed to their free end fixed to the outer surface of a thin-walled tube.
  • the two arms are made as the ends of one open thin-walled body one part of whose length embraces a part of the circumference of the thin-walled tube distant from the gap between the free ends of the arms and the thin-walled body is fixed on the outer surface of the thin-walled tube.
  • the thin-walled tube is made as a cylindrical tube.
  • Such thin-walled cylindrical tube means for the batten only a minimal increase in weight and moment of inertia and considerable increase in its torsional rigidity.
  • the thin-walled tube is made of a composite material.
  • the thin-walled tube is made of steel.
  • Each of these two embodiments is simple, reliable in operation and favourable in price, in particular for obtaining a low moment of inertia of the batten at sufficient strength.
  • the arms are made of a composite material.
  • the composite material consists of a fibre reinforcing material in a polymeric matrix.
  • Such composite materials are sufficiently tested and of well established technology of preparation and production so that their application is facilitated.
  • the fibre reinforcing material consists of mutually oriented layers of separate parallel carbon fibres in a matrix of epoxide resin.
  • This specific type of fibre composite material is particularly suitable by its favourable mechanical properties and low specific weight.
  • Fig. 1 is a cross section of a batten with arms made as ends of an open thin-walled body having inserted therein a thin-walled tube
  • Fig. 2 a cross section of a batten with a pair of independent arms glued onto a thin-walled tube.
  • the batten of a weaving machine comprises an open thin-walled body 1 having at its ends a pair of arms 10 which get nearer to each other in the direction from the axis of rotation of the batten to their free ends 100 , the free end 100 of each of the arms 10 being made as the fixing part of a lower stringer 20 of a reed 2 .
  • a gap 11 for the lower stringer 20 of the reed 2 is provided between the fixing parts of the two arms 10 .
  • the free ends 100 of the arms 10 clamp the lower stringer 20 of the reed 2 by prestressing the arms 10 by means of a plurality of bolts 3 distributed on the arms 10 uniformly along the whole length of fixation of the reed 2 .
  • a thin-walled tube 4 made in this example of embodiment as a cylindrical tube sitting by a part of its outward wall on the inner wall of the single-part open thin-walled body 1 .
  • the open thin-walled body 1 is glued together with the thin-walled tube 4 .
  • the open thin-walled body 1 serves to ensure optimum clamping of the lower stringer 20 of the reed 2 and to transmit the transverse bending stress while the thin-walled tube 4 serves to obtain optimum flexural and torsional rigidity and to transmit the torsional and longitudinal bending stress acting on the whole batten system.
  • the pins for the rotary seating of the batten in the frame of the weaving machine are suitably seated at the ends of the thin-walled tube 4 .
  • the arms 10 are separate, and each of the arms 10 is independently glued onto the thin-walled tube 4 from one side of the thin-walled tube 4 .
  • the thin-walled tube 4 is made as a cylindrical tube.
  • the thin-walled tube 4 is made either of a composite material or of a suitable metal such as steel, and the thin-walled body 1 or the separate arms 10 are made of a composite material or of a light metal. A combination of a composite and a metal is possible.
  • the composite material of which the respective batten part can be produced can be for instance a composite material with a fibre reinforcing component seated in a polymeric matrix.
  • the composite material consists of a system of suitably oriented layers of individual parallel carbon fibres seated in a matrix of epoxide resin.
  • the value of the specific weight of the composite material is approximately 1,5 g.cm -2 .
  • the fibre reinforcing component can consist of another fibre type such as kevlar fibres, and the individual layers need not consist of parallel individual fibres but for instance of a suitably oriented woven fabric made of a suitable type of fibres, or the whole reinforcing component can consist of suitably oriented layers of a woven fabric made of a suitable type of fibres.
  • the matrix of the used composite materials need not be polymeric but can be made of another suitable material or even of a metal. It is also possible to make the two thin-walled profiles of the same composite material or of mutually different composite materials.
  • the mechanical properties of composite materials, and especially of fibre composite materials can be influenced by a specific advantageous orientation of the reinforcing component of the composite material in the individual layers of the reinforcing component (by using the anisotropy of the composite material properties) it is possible to optimize the mechanical properties of each part of the thin-walled profile in relation to the specific expected load.
  • the properties of each specific thin-walled profile can be relatively simply and easily optimized in relation to the expected load of the batten of the weaving machine in question.
