Definitions

  • the invention relates to a circular loom with a machine frame, a lower and upper circular race arranged in the machine frame for guiding a shooter, the rollers of which are fitted between guide surfaces of the upper and lower race, the races having thread guide grooves crossing the guide surfaces.
  • a circular loom of this type is known from DE-B-1 535 586.
  • the rollers of a movable part carrying a cut-off part of the weft thread are fitted between comb-shaped guide surfaces.
  • the comb-like guide surfaces enable the warp threads to be immersed in the thread guide grooves of these guide surfaces, so that contact of the rollers with the warp threads can be avoided.
  • the thread guide grooves are aligned in the radial direction in this known circular loom.
  • the shooters are provided with Kettfadenleitbügeln to fully open the compartment, that the warp threads do not slide into the thread guide grooves, but are deflected from the radial direction due to the contact with the rotating shooter so that they remain on the raised ridges between the thread guide grooves and are thus overrun by the shooter's wheels.
  • the invention aims to avoid these disadvantages and difficulties and has as its object to create a circular loom of the type described above, which is suitable for the highest weaving performance, with a shooter with warp thread guide bar - for completely opening the compartment when the shooter enters the compartment - Can be used.
  • the thread guide grooves are preferably arranged inclined at an angle of at least 1 ° with respect to the radial direction.
  • a particularly easy insertion or sliding of the warp threads into the thread guide grooves is preferably ensured in that the webs lying between the thread guide grooves have tapered extensions at their ends directed towards the center of the shed.
  • the webs lying between the thread guide grooves and carrying the guide surfaces expediently have a greater width than the width of the thread guide grooves, the ratio of advantageously Width of a web to the width of a thread guide groove is about two to one.
  • the thread guide grooves it is also possible to choose complicated cross-sectional shapes for the races.
  • the guide surfaces of the races are expediently inclined inwards.
  • the races are preferably made of plastic, in particular polyoxymethylene or a polyamide, preferably by the injection molding technique, by the injection molding technique or by casting, which makes the races particularly easy to manufacture.
  • the races are composed of initially straight-line sections which are fitted into an annular groove in the machine frame and fastened in this groove.
  • FIG. 1 showing a vertical section through the central axis of a circular loom.
  • Fig. 2 shows a detail of a section along the line II-II of Fig. 1 on an enlarged scale.
  • FIG. 3 is a detail of a view in the direction of arrow III of FIG. 1.
  • the circular loom has a drivable rotor 2 which is rotatably mounted in a machine frame 1 and which is arranged below a fixed circular-cylindrical reed 3.
  • the reed 3 is delimited by a lower and an upper, ring-shaped race 4, 5, along which races at least one shooter 6 is guided by rollers 7. Between the races 4, 5 these connecting rods 8 of the reed 3 are provided, between which the warp threads 9, 10 are passed.
  • the reed 3 concentrically surrounding thread guide members 12 are provided, which are formed by upper and lower guide rollers 13, 14 guided endless belts 15, to each of which a thread guide eye 16 is attached to each strand.
  • the rotor 2 has a groove 17 (or spring) which runs in a wave-like manner over the circumference and on which driver elements 18 are guided.
  • the driver elements 18 are connected to the belts 15 by means of actuating rods 19.
  • thread tensioning devices 20 are provided for the warp threads 9, 10, which are formed by spring wires 21, which are each equipped with thread holders 22 at their free ends.
  • the races 4, 5 have the guide surfaces 23 for the rollers 7 crossing thread guide grooves 24 for receiving the warp threads 9, 10 forming the compartment 11.
  • the depth 25 of the thread guide grooves 24 is selected so that the warp threads 9, 10 do not lie against the bottom 26 of the thread guide grooves 24 when the compartment 11 is fully open (see FIG. 1), but come to lie at a short distance 27 therefrom.
  • the webs 28 present between the thread guide grooves 24 have a width 29 which is twice as large as the width 30 of the thread guide groove 24.
  • the guide surfaces 23 are thus only slightly interrupted by the thread guide grooves 24.
  • the thread guide grooves 24 are aligned with the circumference of the Races 4, 5 arranged, formed by the reed 3 thread guides, the rods 8 of the reed 3 are each arranged in the extension of a web 28 outside the same.
  • the thread guide grooves 24 are not arranged exactly radially to the central axis 31 of the machine, but they deviate from the radial direction in the running direction of the shooters 6 by an acute angle alpha, which ensures the smooth sliding or insertion of the Warp threads 9, 10, which are spread out by thread guides arranged on the shooter 6 and designed as thread guide brackets 32, are secured in the thread guide grooves 24.
  • the insertion of the warp threads 9, 10 is further facilitated in that the thread guide grooves 24 have extensions 34 which are wedge-shaped at their ends directed towards the center 33 of the shed. These projections protrude beyond the guide surfaces 23 and at the same time form a support for the rollers 7 of the shooter 6.
  • the acute angle alpha, with which the thread guide grooves 24 are arranged inclined with respect to the radial direction is preferably more than 1 °.
  • a major advantage of the circular loom according to the invention can be seen in the fact that the warp threads 9, 10 - apart from the drive roller 35 driving the shooter 6 and rotatably mounted on the rotor 2 - only with the thread guide eyes 16 and with the thread guide bars 32 in the area of the compartment with machine parts come into contact so that you have a free hand in the construction of the guide surfaces 23 of the races 4, 5.
  • the guide surfaces 23 are arranged inclined inwards and the upper guide surface 23 is provided with a support for the upper wheels 7 of the shooter 6, via which Guide surface 23 protruding inner edge 36 which prevents the shooter 6 from tipping inward when it is stationary.
  • the races 4, 5 are advantageously made of plastic; they are assembled from initially straight-line sections, the individual sections having a foot 37, each of which is fitted into an annular groove 38 of the machine frame 1 and is fastened in this groove 38, for example by means of screws 39.
