BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a drive mechanism for a continuous weaving loom. barbs formed in the picking apertures of two opposing picking plate systems engaging in oblique grooves on the upper and lower surfaces of the inserters.

Dosavadní pohon zanášečů útku konti-nuálních tkacích stavů je ovládán vratněnebo rotačně pohyblivými prohozními la-melami, působícími střihovými tlaky přímona zainášeč, nebo je tento pohyb vyvozovánpárem válečků, z nichž hnací, uložený mi-mo prošlup, působí na hnaný, uložený otoč-me na zanášeči útku uvnitř prošlupu, při-čemž se oba válečky odvalují po dolní polo-vině prošlupu. Jiný impuls pohonu zanáše-čů může vycházet z válce, uloženého vesměru útku mimo prošlup a opatřeného šrou-bovicí na povrchu, jejíž závity při rotaciválce postrkují zanášeč, nebo může být za-nášeč postrkován růžně upravenými páka-mi, zasahujícími postupně do prošlupu apostrkujícími zanášeč. Všechna uvedená prohozní zařízení majíprovozní nedostatky. Přímým působením ro-tujících nebo kývajících lamel na zanášečse deformuje zanášeč i lamely působenímstřihových tlaků, při postrku zanášečů ro-tujícími hnacími válečky vně a uvnitř os-novních prošlupů trpí otěrem dolní část 2 prošlupu mezi těmito hnacími válečky, při-čemž nástavná zařízení, snižující otěr osno-vy, zvyšují automaticky poruchovost stroj©a páky, zasahující postupně clo prošlupu apostrkující zanášeče, jsou pro vyšší rych-losti tkaní příliš těžkopádné.The current drive of the weft inserters of the continuous weaving looms is controlled by the reciprocating or rotationally movable weft labs, the shearing presses acting in a straight line, or by a pair of rollers, of which the driving, mounted mine shed, acts on the driven, rotatable on the weft inserter inside the shed, with the two rollers rolling along the lower half of the shed. Another pulse drive of the plugs may come from the cylinder, the deposited weft space out of the shed and provided with a screwdriver on the surface whose threads push the plug in the rotating cylinder, or the plug may be pushed by the pink levers extending gradually into the shed and spraying the plug . All said picking devices have operational drawbacks. The direct action of the slats or the slats on the insert causes the slats to deform by the shearing pressures, while the squeegees of the squeegee-driving drive rollers and the inner sheds suffer from abrasion the lower shed portion 2 between the drive rollers, the attachment devices decreasing The abrasion of the pusher, increases the failure rate of the machine automatically, and the levers, which gradually reach the duty of the shed and the feeder, are too cumbersome for higher weaving speeds.

Uvedené nedostaky řeší zařízení, podle vy-nálezu tím, že šroubovité a protichůdně se-řazené prohozní otvory v prohozních lame-lách jsou opatřeny ozuby, zasahujícími došikmých drážek na vrchních a spodních stra-nách zanášečů útku.The aforementioned drawbacks are solved by the device according to the invention in that the helical and oppositely aligned pick holes in the picking lamellae are provided with claws extending from the sloping grooves on the top and bottom sides of the weft inserters.

Pohon člunků kontinuálního tkacího stavupodle vynálezu, znázorňuje přiložený sche-matický výkres, kde obr. 1 značí v příčnémřezu dvě známé soustavy protichůdně rotu-jících prohozních lamel, uložených ozubený-mi středovými otvory v odpovídajícím pří-mém drážkování na povrchu prohozních hří-delů, jednu soustavu nehybných lamel vodi-cích rovněž s prohozními otvory, avšak vět-šími a uspořádanými v přímce směrem út-ku, zasouvanými střídavě mezi lamely pro-hozní a napínanými nosníky vodicích lamel,potažených novou hmotou, nebo opatřenouzářezy, podle· požadavků rozteče.The shuttle drive of the continuous weaving loom according to the invention is shown in the accompanying schematic drawing, in which Fig. 1 shows two known sets of oppositely rotating picking lamellae mounted in the cross-cut in the corresponding straight grooves on the surface of the picking shafts, a plurality of stationary slats also with picking holes, but larger and arranged in a line of weft insertion alternately between the slats and the tensioned beams of the guide strips, coated with new mass, or provided with grooves, as desired.

Claims

In order to achieve the required density of the slats, the production of the radial type is eliminated. FIG.

Figure 2 shows, in longitudinal section, two sets of picking lamellae on two picking shafts, between which the spacers are arranged, each of two bases together according to Figure 5, with a height V between their bases and the height on the circumferential line, is a decisive figure in the warp , by grinding this line accurately. Between the two sets of pick-ups, alternately inserted from the top and bottom pick-up shafts, lamellas are inserted through the guide, whereby the density of this device rises twice, so that even the densest fabrics can be woven, with no density detriment. rotating shovel blades with a density of one quarter of all slats in the weaving area. The inserters moving in the transverse tunnel from the holes in the guide vanes are always pushed simultaneously by a plurality of teeth formed in the apertures of the picking lamellae and falling into the oblique grooves on the upper lower sides of the inserters without contact with the pine. By rotating the pick plates and then the teeth in the sense of the arrows in FIG.

3, the pressure of a plurality of teeth is simultaneously applied to the sloping walls of the grooves on the top and bottom sides of the grooves in a desired direction without contact with the pine, and this kinematic binding allows the entire state to be stopped in the path of the slipper. FIG. 3 is a top plan view of the weft insertion device with the possible insertion of two weft coils parallel to each other, indicating oblique grooves on the top and bottom sides of the toothbrush and the spray of the teeth in the direction indicated. FIG.

4 is a direct view and FIG.

Fig. 5 is a side view of spacers with bent edges, with a height V precisely ground in accordance with the present invention;

6 is a front elevational view of a guide lamella carrier with notches defining a warp, and it is also possible to utilize the properties of the new material of the guide lamella carriers into which the guide lamellae are cut by the tensile screws (not shown) on the bars. in the sense of arrows. The drive of the continuous weaving boat shuttle according to the invention is made up of two known, counter-rotating counterparts of the rotating lamellae of the propellers 1, arranged by picking openings 2do of the elongated helices and secured for spontaneous rotation by the teeth 4 engaging the corresponding straight grooves 5 on the surface shafts 3. On the picking lanes 1, a picking openings are formed at regular distances around the center. OBJECT Drive the shutters of continuous weaving looms with three sets of slats characterized in that the helical and oppositely arranged thrust holes (2) in the picking slats (1) 2 with weft outlet slots 6 provided in a curved shape of the involute to provide a beating of the weft to be drilled at each straight point perpendicular to the warp plane. The picking holes 2 in the picking fins 1 are larger than the guide holes 7 in the guide fins 8, so that the weft inserters 9 passing through the continuously formed shed are guided only through the holes 7 through the guides 7 whose exact spacing on the guide fins 8 is provided by tension bolts (not shown) in the sense of the arrows in FIGS. 1 and 5, whereby the ends 10 on the guide blades 8 fit into the slots 11, or the guide plates 8 are cut into the coating from the new masses on the slots 16, the tongue 12 in the apertures 2 of the picking blades 1, when rotating the picking rollers 1, will gradually engage the top and bottom sloping grooves 13 in the weft inserters 9 and, when moving in the sense of the arrows in FIG. 3, ensure their forward movement without the warp shed. With the density of the discs 1, the spacers 14 inserted between them, bent on the circumferences and the central openings 15 placed on the shafts 3, determine each one of the bases according to FIG. 5, the bending height V being precisely determined by grinding the circumferences of these spacers 14 . The toothing 4 on the picking laps 1 corresponding to the straight grooving 5 on the surface of the shafts 3 makes it possible to form any thread pitch from the picking openings 2 by simply swiveling the picking blades 1 on the threading shafts 3, thereby making the described apparatus much more powerful. the nozzle state by forming approximately one thread from the drive holes 2 to the entire width of the fabric. It is also possible, without changing the described device, to use the gripper weaving to create the gripper guides from the direct guide holes 7 in the guide shafts 8 and to confuser them from the nozzles. In doing so, the production of picking lamellas 1 and guide shafts 6 by cutting out the sheet is very easy and easy to assemble, consisting of pre-folding the lamellae into one another without the use of a non-conventional, especially produced beam. At the same time, the calm, predominantly rotational movement of the shocks and production can be increased by a factor of two by placing the two described states in pairs with the warp beams to the side, the weft inserters 9 being then circulated between the two states in the horizontal plane and weft filling, located at the side of the two states. The 2 sheets of the drawings are provided with claws (12) extending into the inclined grooves (13) on the upper and lower sides of the weft inserters (9).
