Definitions

  • the invention relates to a row shed weaving machine with a weaving rotor on which, in the direction of rotation, alternately stop combs formed by stop lamellae for the weft threads and guide combs formed by guide lamellas for the warp threads and containment elements for the high shed position of the warp threads are arranged, and with a in the running direction of the warp threads before Webrotor arranged control means for lateral deflection and optional assignment of each warp thread to a shed holder.
  • each stop comb alternately contains first and second stop slats and each guide comb alternately contains first and second guide slats, the second stop and guide slats compared to the first at the points of the slat combs which first enter the warp threads during the rotary movement of the weaving rotor each have a recess, and that the lateral deflection of the warp threads by the control means reaches its maximum after immersing the first stop or guide slats.
  • the tube into which the respective warp thread is to be read is twice as wide as it is without these cut-outs at the moment each lamella comb is immersed in the warp thread coulter, so that each warp thread is sure to get into the double-width tube.
  • the warp threads are laterally deflected even more strongly by the control means and are laterally applied to the already immersed first stop or guide slats which delimit the double-width tube.
  • the warp threads are positively guided into the then normal-width tube when the second slats are immersed and are reliably read into it. Reading the warp threads into the double-width tube can be made even easier by arranging the stop and guide combs in a mutually displaced manner, as in US Pat. No. 4,290,458.
  • the weaving rotor of a row shed weaving machine has a hollow roller 1 which extends across the width of the weaving machine and which is supported on its end faces by tubular stubs 2 mounted on the machine frame (not shown). During operation, the weaving rotor rotates in the direction indicated by an arrow P in the figure.
  • the structure and mode of operation of a series shed weaving machine with a weaving rotor are assumed to be known and are not explained in more detail here; in this connection reference is made to US Pat. No. 4,290,458.
  • stop and guide combs 3, 4 are arranged parallel to the longitudinal axis thereof.
  • the stop combs 3 contain first and second stop slats 5, 5 'for striking the inserted weft threads
  • the guide combs 4 contain first and second guide slats 6, 6' for the warp threads K.
  • the lamella combs 3 and 4 When the weaving rotor rotates in the direction P, the lamella combs 3 and 4 first immerse themselves in the warp threads K at the corners of the first lamellae 5 and 6, which are denoted by 15 and 16.
  • the second lamellae 5 'and 6' differ from the first lamellae 5 and 6 in that they each have a cutout 17 and 18, respectively, at those points which first dip into the warp threads.
  • the guide slats 6, 6 ' are provided with shed retaining elements for the high shed position of the warp threads K, which are formed by projections 7, 7' projecting laterally from the guide slats.
  • Each first guide plate 6 is provided with a projection 7 and every second guide plate 6 'is provided with a projection 7', which protrude from the guide plates 6, 6 'on different sides and are offset with respect to one another in the warp direction.
  • each tube that is, the space between adjacent guide fins 6, 6 'is alternately provided for the up or down position of the warp threads K.
  • the respective compartment holding member is formed by two projections 7, 7 ′ projecting against each other. Because of the offset of these projections in the warp direction, the tube width can be adjusted between the single and double the value of the laterally protruding height of the projections 7, 7 '.
  • the first and second stop plates 5, 5 'of the stop combs 3 on the one hand and the first and second guide plates 6, 6' or guide combs 4 on the other hand are each aligned and the alignment lines of the individual guide plates 6 and 6 'run in the middle of the tube of the stop plates 5 and 5 'and vice versa.
  • the stop plates 5, 5 'of the stop combs 3 are thus along the first and the guide plates 6, 6' of the guide combs 4 are arranged along the second circumferential circles on the hollow roller 1 and both types of circumferential circles are mutually divided by half, that is by one half pipe width shifted.
  • first stop lamellae 5, corresponding second stop lamellae 5 ", corresponding first guide lamellae 6 and corresponding second guide lamellae 6 'of all lamella combs 3 and 4 each lie in common planes, that is to say they are in each case in alignment with one another the number of guide channels F corresponding number of dovetail grooves parallel to the roller axis, each of which is provided for receiving a common support for one stop and guide comb 3, 4 each.
  • this carrier consists of two mutually parallel rails 8, 9, of which the rail 9 is provided with a dovetail corresponding to the dovetail groove mentioned.
  • the rail 9 is distributed over its length at intervals of approximately 5 to 10 cm with threaded bores, into each of which a countersunk screw 10 is screwed, which protrudes with one end from the rail 9 and presses against the rail 8. The distance between the two rails 8 and 9 can be adjusted by turning the screws 10.
  • Each lamella 5, 5 'and 6, 6' has two fastening legs which enclose a mouth II or 12 which partially surrounds the rails 8, 9.
  • the mouth II, 12 of each lamella 5, 5 'or 6, 6' is delimited at the end of each fastening leg by a projection. These projections are provided for snapping on two diagonally opposite edges of the two rails 8 and 9.
  • the width of the mouth II, 12 and the cross section of the rails 8, 9 are dimensioned such that when the screws 10 are loosened, that is to say when the two rails 8 and 9 are at a small mutual distance, the lamellae 5, 5 'and 6, 6' with their Attachment legs can be placed over the rails 8, 9 and then fixed by adjusting the screws 10.
  • Each carrier formed by the rails 8, 9 carries two lamella combs which are displaced relative to one another by half a pitch or tube width, a stop comb 3 with first and second stop lamellae 5, 5 'and a guide comb 4 with first and second guide lamellae 6, 6'.
  • Each carrier is fixed in its dovetail groove.
  • the geometry of the lamella comb 3, 4 on the weaving rotor is designed such that when a warp thread K in the guide channels F alternately assumes the high or low position, that is, always between the projections 7, 7 ' one particular and the next Guide comb 4 is tensioned, the point of intersection of the warp thread sheets is always in the space between the stop and guide comb 3 or 4 of each pair of lamella combs carried by a common carrier.
  • large warp densities i.e. small distances in the weft direction between the slats, this facilitates the shed movement of the warp threads K.
  • warp threads K loop around the weaving rotor in this way and, moreover, always take the up or down position alternately within each guide comb 4, as seen in the weft direction, then this corresponds to a 1/1 or plain weave.
  • the warp threads K due to their tension between the projections 7, 7 '- of the various guide combs 4, automatically assume the low position in every second guide channel F. It would therefore not be necessary for this binding to have any special shelf holding devices.
  • FIGS. 3 and 4 show, on the basis of a schematically illustrated development of a stop comb 3 and a guide comb 4 with the control means for the lateral deflection of the warp threads K, their reading into the slat combs and the function of the second stop and guide slats 5 provided with the cutouts 17 and 18 ', 6'.
  • the two figures represent two different stages of the import process.
  • the two fin combs 3 and 4 with the fins 5, 5 'and 6, 6' are mutually displaced by half a pitch or tube width.
  • the warp threads K are guided in the sheathing threads 19 and 20 arranged in front of the weaving rotor in the running direction of the warp threads and run from these to the lamellar combs 3 and 4.
  • Each shed bit rods 19, 20 each have the same binding warp threads K, that is to say warp threads, each of which together in the upper - or lie in the sub-compartment.
  • the individual lamellae 5, 5 'and 6, 6' are each symbolized by a thick full line, the recesses 17 and 18 on every second stop and guide lamellae 5 'and 6' are not fully drawn out, but are surrounded by thin lines.
  • the guide comb 4 under consideration is fully immersed in the warp threads K and the stop comb 3 begins in FIG. 3 with its plunging movement. Due to the fact that every second stop lamella 5 'is provided with a recess 17, the warp threads K do not have to be read into a normal-width tube A in the first stage of immersion shown in FIG. 3, but can be read into a double-width tube 2A. The same applies to the immersion of the guide combs 4 with the tubes B. It is obvious that the double-width tubes considerably increase the security of the correct reading in of the warp threads K.
  • the shed forming rods 19, 20 designed as toothed racks have been moved by their drive in such a way that the warp threads K assume the positions shown.
  • the warp threads K guided by the shedding rod 19 were moved to the left (arrow C) and the warp threads K guided by the shedding rod 20 were moved to the right (arrow D), in each case into a position where they were certainly in the double-width tubes width 2A can be read.
  • the two stages of reading in the warp threads K can run in a continuous process and merge into one another, but they can also be carried out discontinuously, that is to say in two separate steps. It is essential that during the first stage the reading into a double-width tube is carried out in a sort of pre-sorting and then during the second stage the reading into the final, normal-width tube, the warp threads K being fed positively into the tube in the second stage.
  • each of two lamella combs 3 4 on a common carrier and it would of course also be possible for each stop and guide comb 3, 4 to be suitably arranged on the hollow roller 1.
  • the shape of the organ 13 is arbitrary within wide limits; for example, the compartment holding members for the deep compartment position could also be formed by projections on the stop or guide slats. In any case, however, it is advantageous if these shed retaining elements are arranged at the point of intersection of the warp thread sheets. The location of this crossing point can also vary and depends on the selected geometry. The crossing point could also lie within the stop or guide combs 3 or 4.
  • the relevant stop or guide lamellae 5 or 6 would have a corresponding bore through which the organ 13 would have been pushed, or they would be provided at the corresponding point with projections serving as a specialist organ for the lowering of the warp threads.
  • the stop and guide combs 3, 4 are mutually displaced by half a division, because up to a certain value of the warp density, the warp threads can be read into the double-width tubes without this displacement.
  • the mutual displacement has the advantage, however, that even in the first stage of the reading-in there is a kind of positive guidance of the warp threads in that they can be brought into contact laterally with the fins that delimit the tube in the previously immersed fin comb. If, in the first stage, the warp threads K were laterally deflected to such an extent that they would definitely get into their final tube, then in the case of large warp densities, warp threads K could jump into an adjacent wrong tube. This danger is eliminated by the cut-out on every second lamella, since this ensures reliable reading into a double-width tube even with a slight lateral deflection of the warp threads.
