The invention is applied to a conventional chain drawing machine with which the warp threads of a warp beam 10 are passed through various weaving elements, namely through the warp frame 11 and a Rie.tkamm 12 in preparation for the insertion of the warp beam into a loom. The warp beam loading ^f can be found under the bed 13 of the machine, and the warp threads are guided in known manner to the top and releasably clamped to the Gebrauchs3teile. The warp threads are grasped by an elongated needle 14 (Pig. 2 and 3), which is passed through the individual gaps in the reed comb from the opposite side and pulled through the reed comb on the return movement.

The conventional device for guiding the needle 14 back and forth is on the left side (Iig.2) of a carriage 15 (ü'ig »1) attached, which is mounted horizontally movable on the guides 17 on the bed and the needle step by step along the reed comb 12 moved on and on the individual gaps in the Rietkamines one after the other aligns. The Rietkammeina part device is also on the car 18 attached, which moves with the rebuke, and adjacent teeth 19, 20 sets the 3 reed comb to pass the needle through; one or more threads being drawn through each gap in the reed comb depending on the type of fabric to be produced.

The actuation of the various elements of the loom in the predetermined order takes place with the aid of a conventional control device 2t in the form of a stencil wagon, the preferably from the US Pat. No. 2 400 342, and in which a perforated Sample sheet or tape (not shown) is used, to choose between the various drive connections between the working machine elements and a power source, The reed comb is supported on rollers 22 and 23, as in FIG Fig. 2, and with respect to the machine bed 13 in the longitudinal direction can be shifted to a limited extent, for what purpose the Adjustment device 18 is used · This displacement is of a switch 24 (Figure 3) determined by a rod 27 with an actuator 25 is actuated, which rod protrudes from one end of the reed comb. If the switch is closed, the carriage drive receives power and moves the carriage in the corresponding direction, in the present case according to FIG right .. In some cases, the back and forth movements are made Needle so rapidly on top of each other that the carriage is essentially steady

is moved forward »while in other cases the movement is irregular is. The arrangement described above is for chain pulling machines conventional and described in detail in U.S. Patent No. 2,807,861.

The reed comb consists of a plurality of flat and flexible wires attached at both ends to an upper and a lower rod 28, which rods are united at the opposite ends by strong cross members 29 to form a rectangular frame. As can be seen from the Mg ₀ 3, the one cross member carries a protruding rod 27 for actuating the switch 24. So far ... all ... teeth of the reed comb were arranged in a single row, as described in the above patent, and the adjustment device acted on the teeth from one side of the reed comb to regulate the position of the teeth with respect to the path of travel of the needle. Since the development of the double reed combs, in which the teeth are arranged alternately laterally offset from one another, whereby a second row of teeth is formed, the conventional adjustment devices could no longer be used

According to the invention, existing chain pulling machines be set up in such a way that double reed combs are offset against each other with the help of two, creating a gap Teeth 19 * 20 can inevitably be set so that such Rietkämme need not be threaded by hand »For this purpose, two adjustment devices 30 and 31 are arranged on both sides of the Rietkammea, whereby the parts 32 of two adjustment blades with a predetermined thickness are located in a common plane and from opposite sides into one

BADORLGiNAL

Enter a gap in the reed comb, said thickness being preferred is at least equal to the normal width of a tooth gap and, in some cases, can be slightly larger, the two sheets become inserted into a tooth gap for threading, the opposite sides of the sheets are on the opposite sides of the two offset teeth that form the gap. The leaves therefore inevitably act together on the teeth, holding them Tooth gap open and generally at the level of the holding parts 32 centered so that the needle H is inserted along this plane can be"

After a first gap has been threaded, one of the leaves is withdrawn from the reed comb, moved around the adjacent tooth 19 or 20 of the adjacent row and inserted into the next tooth gap, while at the same time the other leaf is offset in the longitudinal direction of the reed comb and in the Level of the other sheet remains, with the sheet in the Moved next gap After threading this gap, the second sheet withdrawn, moved around the opposing tooth and introduced into the next gap, while * the first Blade in the longitudinal direction of the reed comb follows this idle movement. In this way the reed comb and the teeth automatically set progressively from one tooth gap to the other.

Although the sheets can be designed in different ways, preferably apiralig extending leaves are used as shown in Figures 3-5, the Bind provided on rotatable Einstellglie- AIN 30 and 31, which adjustment members arranged side by side and ^'L timr parallel axes either side of the reed comb rotatably are which ^; Axes in the longitudinal direction of the Riet & Ammes

ORIGINAL BATHROOM

Both bin setting devices can consist of the embodiment described in the American patent Hr ₀ 2 807 861, which has a bushing 33 which is pushed onto one end of an axle 34, 35, the spiral blade of a

37
on the socket provided collar protrudes outward and extends around the socket. At the front end of each blade there is a generally radially extending engaging edge 38 'from which the blade 39 spirals around the axis of the adjusting member to the holding part 32 which is located in the plane common to both adjusting members. The holding part is to be dimensioned as wide in all cases that the teeth are held apart a sufficient distance for inserting the needle _o Thus, a gap 40 is formed, through which the sheet with the rotation ^in: can be led around a direction by one tooth as in 2, 4 and 5 indicated by the arrows 41, the sheet ends in a rear edge 42 which is axially spaced from the engaging edge 38 and is preferably beveled »This edge tapers so that it fits into the narrow gap between can be inserted into the teeth without difficulty *

It can be seen from FIGS. 4 and 5 'that the back side 43 of each sheet can be brought into engagement with the opposite (upper) sides 19a, 20a of the teeth, while the front sides 44 of the sheets with the opposite sides 19b, 20b the teeth can be brought into engagement, according to the figures 4 and 5 the lower sides of the teeth are 'are introduced the two sheets into a gap of the reed comb, so that the respective retaining pieces 32 face each other (FIG _e 4), soliegt: > the, back 43 of the right sheet on the opposite side 1'9a of the first tooth 19 of the right row,

while the front 44 of the left sheet on the opposite Side 20b of the offset first tooth 20 of the left row so that each leaf rests only on the tooth in the row that is closest to the leaf. The two with the leaves meshing teeth are therefore separated from each other in one Maintained distance that is equal to the thickness of the holding parts 32, the is to be dimensioned so that there is enough leeway for the needle 14 With finer Rietkänmien with, a relatively large one Number of teeth per unit length are the teeth over their normal distance apart from each other. With coarser reed combs, the normal distance between the teeth can be used as a margin enough for the needle. In addition, the two gaps 40 are at a distance of approximately 180 ° from one another, and the thrust of the two leaves takes place in the same direction, while the Attack edge 38 of each sheet in the rest position at a distance is located at the plane of the side edges of the adjacent row of teeth *

After a warp thread has been drawn in as the needle 14 is passed through the reed comb 12 along the center line shown in FIGS. 4 and 5, one of the adjustment members 30, 31 is rotated through a predetermined angle, in the present case over 360 ° the operating state shown in FIG. 4, the left adjusting member 30 is rotated first. While the tooth 20 is completely or almost in contact with the front side 44, the engaging edge 38 moves to the right in front of the tooth, the gap 40 having a greater width in the axial direction than the width of the tooth, which after one revolution of the adjusting member a on the Rear side 43 of the sheet rests, as shown in FIG. During this process, the tooth becomes 20 and thus

the reed comb 12 through the screwing action of the single member 30 pushed backwards, the switch 24 being actuated with the consequence that the carriage 15 is moved forward until the switch is reopened, the result consists of relative movement of the adjustment members and the needle 14 in the longitudinal direction of the reed comb, while the holding parts 32 in the plane of the movement path 45 of the needle remain »This relative movement can of course also be achieved if the storage for the Adjusting members are held in place and the reed comb is moved in the longitudinal direction »In any case, the leaves move together into the next tooth gap of the reed comb, whereby the

™ opposite sides of the holding parts 32 to the opposite Place the sides of the two offset teeth 19 »20 that form the gap through which a warp thread is drawn in»

After that, the second or right single-gear member 31 rotated 360 ° from the position shown in Mg.5. During the initial rotation, the engaging edge 38 of this adjusting member moves in front of the tooth 19 »so that the blade slides in the effect around the tooth into the next gap, while the other Blade moves ineffectively in the same tooth gap »Also in this-

In this case the two leaves act on the teeth 19-20, the form the gap and keep the teeth separated from each other while threading.

The two adjusting members 30, 31 are therefore alternately rotated so that the adjustment device acts first on one row and then on the other row of teeth, wherein maintain control of the active teeth in both rows will. The likelihood of the teeth from the attacking edges 38 of the leaves to be scratched is very slight as the position

of the tooth that is passed is carefully "determined". Compared to reed combs with a single row of teeth, that have a small distance from each other is the frictional resistance against the movement of the leaves smaller because of the greater longitudinal distance of the teeth from one another, and because the teeth are less stand together

Another important advantage of this adjustment device is the fact that a chain pulling machine is different from the one in the American patent specification Ur <> 2 400 342 the embodiment shown, set up without difficulty for operation with double reed combs; «A second axis 35 is provided on the side of the reed comb that is opposite to the original axis 34, on which an identical adjusting member 31 is mounted and actuated alternately by the stencil sheet with the first adjusting member that is used for another machine element in exactly the same way - in which the original adjuster did a reed comb is operated with only one row of teeth.

The details of the arrangement and storage of the two adjustment members 30 and 31 are shown in Mgo2, from the it can be seen that the adjusting member 30 is on the free end a horizontal rod 47 is supported, which is at the most upright-Ii end of the leg 48 of an Ix-shaped slide is attached, the back and forth on a carriage rail 49 on suitable guides 50 is mounted movably. One in the rail and one off the Sides downwardly protruding pin 52 hooked in spring 51 pulls the slide to the reed comb 12 in the normal working position, which is determined by an adjustable stop screw 53 on the slide which screw on the opposite surface 54 ■ on the rail «,

As shown in Fig. 2, is hinged to the carriage at an upright member 57, which is approximately in the middle at 58 with the rail and "at 59 at the upper end with the opposite

60
protruding side of a plate is articulated, which is mounted on the rail above the bidder comb in the transverse direction so that it can move back and forth «From the other side of the plate, a mounting member 61 extends downward, on which the other adjusting member 31 is rotatably attached ο

The opposite ends of the axles 34, 35 of the Sinst@lljglied.er extend to the right according to FIG. 1 to the control device 21 «

In this arrangement, the two adjusting members 30, 31 are held in the Uormalstteilung shown in Figo2, in which the two blades of the adjusting members face each other protrude into the reed comb 12. The distance between the leaves (Fig <> 4 and 5) is determined by the setting of the stop screw 53 (Mg.2) In order to remove the adjusting members for inserting or removing an egg comb from one another, the Sehlitten pushed against the train of each 51 to the left. This movement is via the member 57 and the plate 60 on the mounting member 61 transmitted, which moves the adjusting member 31 out of the working position to the right. After letting go of the slide the spring 51 leads both adjustment members to that shown in FIG Position back.
