Definitions

the invention relates to a row shed weaving machine, equipped with a weaving rotor, which is alternately equipped on the circumference with shed-forming guide elements which are designed as weft channels and with stop combs, and equipped with laying elements which are of the order of magnitude of several comb spacing angles ⁇ against the direction of rotation of the weaving rotor the fabric stop edge are shifted on the circumference and have a low inventory to the rotating guide elements and stop combs, and which, controlled and coordinated according to a program, shift the warp threads transversely to the direction of rotation for the rotation of the weaving rotor, so that these are inserted in the gaps provided for the combs and the guide elements.
Row shed weaving machines have so far been mainly used for the production of loose curtain fabrics and gauzes, in which the warp thread spacing is a multiple of the warp thread thickness.
a series shed weaving machine with weaving rotor is shown in DE-OS 23 18 795.
Ueber the design of weaving rotors on row shed looms is provided by the patents SU 186 898 and EP 0 196 349, while the shed formation is described by laying elements in the patents SU 277 634 and EP 0 012 253.
Laying bars are also used in curtain rustling machines (eg type G 517 ORN / G) from LIBA Maschinenfabrik GmbH., D-8676 Naila. Stop combs in row shed looms and their design are shown in the patents EP 0 111 071 and EP 0 137 071.
the dimensions of the guide and laying elements which cannot be reduced to any size, and their interaction play an ever greater role for the fabric quality.
an undesired warp streak should be avoided, which is understood as a systematic deviation of the distance between two adjacent warp threads from an average warp thread spacing in the fabric.
the invention remedies this. It solves the task of reducing warp streak even with small, medium warp thread spacing and producing a more homogeneous fabric.
the object is achieved in that the gaps of a stop comb occupied with warp threads have at least two warp threads, that the laying elements on the circumference of the weaving rotor are shifted by an even multiple of the comb spacing angle ⁇ and by a tension angle x from the fabric stop edge by a predetermined one to achieve a fluctuation ⁇ 1 dependent on the tension angle x from the warp thread warping, and that warp threads are positioned transversely to the direction of rotation with the striking of two successive weft threads under oblique pull from the side face of a submerged tine of a comb.
the advantage of the invention can be seen in the fact that it can also be used to produce fabrics with denser warp thread spacings without the occurrence of warp stiffness on row shed looms.
the dependent claims 2 to 11 relate to advantageous developments of the invention.
the figures show the warp thread running and the shedding in the area of the weaving rotor 11 of a row shed weaving machine.
the weaving rotor 11 is alternately equipped with twelve compartment-forming guide elements 12 and with twelve stop combs 15 in the circumferential direction.
the stop combs 14 have gaps 25, into which two warp threads are inserted, apart from the fabric edge, while the lateral guidance is carried out by prongs 23.
the clear width 26 of a gap 25 corresponds approximately to twice the width 27 of a tine and the comb pitch 29 corresponds to twice the ideal warp thread division.
the guide elements 12 have high guides 19 and deep guides 20, in each of which a plurality of warp threads are inserted, in order to create space for side boundaries of high guide channels 35 and deep guide channels 36 even with small average warp thread spacings 41.
a large part of the warp threads inserted in a lifting channel 35 or deep channel 36 is deflected transversely to the direction of rotation 10 relative to its ideal stop position and must be returned to the ideal position for the stop.
the distance between the raised guide 19 and the deep guide 20 corresponds to the height of the compartment 14 and is chosen so large that a weft channel 13 for a weft thread 9 is accommodated therein.
the ridge spacing angle ⁇ which is also the spacing angle of the guide elements 12 corresponds in this case to 1/12 of 360 °, ie 30 °.
a plurality of compartments 14 are formed, in which laying elements 31 are arranged on the circumference at a distance of the order of several comb spacing angles ⁇ against the direction of rotation 10 of the weaving rotor 11.
the laying elements 31 are arranged at a distance 32 of less than 2 mm from the highest points of the stop combs and parallel to the axis of the weaving rotor 11. They consist of rails with guide holes at a distance from the warp thread repeat. With a rail, for example, the warp threads 8, 8 ', 8 ⁇ etc.
the laying elements 31 lay their warp threads alternately in high guides 19 and low guides 20 so that compartments 14 are formed. In addition, they place the warp threads in the gaps 25 of the combs 15 provided for attachment to the fabric.
the elevated guides 19 and deep guides 20 lose their effect as a lateral guide and give the warp threads the possibility of being transverse to the direction of rotation 10 under the prevailing pretension between the fabric stop edge 18 and the subsequent stop combs 15 realign.
the warp threads are laterally fixed in the fabric 30.
the warp streakiness of the fabric 30 reflects how well it is possible to align the warp threads in a desired shape before the weft threads 9 are struck. This becomes all the more difficult the more warp threads have to be combined in a gap 25 of a stop comb 15 due to lack of space when struck.
the position of laying elements 31, the geometry and position of combs 15, 16, 17, 28, the position of up and down guides 19, 20 and the laying program are coordinated with one another, that the warp streak is controllable.
a laying element 31 and a laying element 31 shifted by 2 ⁇ on the circumference of the weaving rotor 11 have the same effect on the fluctuations of the warp thread warping and thus of the tensile stresses in the warp thread, which are essentially caused by the fluctuation in the number of meshing or Deep guides 19, 20 arise for this warp thread.
the installation location of a laying element 31, which is defined by an even multiple of the comb distance angle ⁇ and a tension angle x, corresponds to an angular distance 2n ⁇ + x from the tissue stop edge 18.
⁇ f ( ⁇ l) depending on the largest and the smallest warp thread warping, but also the time course of tension during the realignment of the warp threads from the lateral release by up and down guides 19, 20 to the striking of the weft 9 by a subsequent comb 15.
a desired tension curve is generated in the warp thread by the angular distance 2n ⁇ + x of the laying element 31.
the laying elements 31 are staggered in groups 33 as close as possible to the circumference of the weaving rotor 11 in order to generate similar tension profiles in the warp threads during the fastening. Accordingly, they can be arranged between a maximum fluctuation ⁇ l 38 from the warp thread warping and a minimum fluctuation ⁇ l 39.
the repeat for laying the warp threads is also determined.
the laying pattern is repeated in an 8 division of the warp threads transversely to the direction of rotation 10 and in the direction of rotation 10 at an angular distance of two comb spacing angles ⁇ . 3 to 6 typical laying pictures are shown, the differences of which are described below.
the illustration corresponds to a schematic development on the weaving rotor 11, the distances between combs 15 and guide elements 13 being greatly shortened.
the warp threads are in the area of a riser channel 35 in the upper compartment drawn black while they are shown in the area of a deep channel 36 as broken lines.
Fig. 3a stop combs 15 are shown, the prongs 23 and gaps 24 are aligned with each other in the direction of rotation 10, with tines 23 alternating with prongs 37 which have a short profile in the direction of rotation 10 and transversely to the direction of rotation, which brings space advantages when inserted.
every second tine 23, 37 is aligned with the center line of an upward or downward passage 35, 36.
the clear width 26 of the gaps 25 corresponds approximately to twice the width 27 of a tine 25, 37.
the comb pitch 29 transverse to the direction of rotation 10 corresponds to twice the ideal warp thread spacing.
the warp thread spacing 41 between two adjacent warp threads when struck varies relatively widely.
the stop comb 15 can be designed as a double comb, as in FIGS. 5a, 5b.
the double comb consists of an auxiliary comb 28, which is preceded by a main comb 16 in the direction of rotation 10.
the division 29 of the auxiliary and main combs 28, 16 is the same. However, these are laterally offset from one another by half a pitch 29 so that the warp threads, which frame a prong 23 of the main comb 17, lie together in the subsequently aligned gap 25 of the auxiliary comb 28.
the main combs 17 are aligned with one another in the direction of rotation 10, while in FIG. 5b every second main comb 16 is laterally offset by half a comb pitch 29.
a straightening comb 17 is shown, which is mounted as a single comb outside of the weaving rotor 11, and is briefly immersed in plunge areas 42 between the warp threads at every second weft stop before the stop comb 15 and before the weft thread 9, in order to assist them in aligning.
the tines of the straightening comb 17 are tapered to increase the accuracy.
the immersion movement of the straightening combs 17 can also contain movement components in the direction of rotation 10, on the one hand to separate the warp threads in clear immersion areas 42, 43 and on the other hand to achieve a directional effect as close as possible in front of the striking comb 15.
tines 23 of a straightening comb 17 plunged behind a striking comb 15 in the tracks of the tines 23, with the tapering tines 23 deliberately pushing warp threads toward the middle of the gap than through the side faces 24 of striking Tines 23 happens.
