DE2125470C3 - Method and apparatus for making a slide fastener by weaving - Google Patents

Description

The invention relates to a method of manufacturing a slide fastener by weaving Patent 2,023,005, where a link-forming profile strand is used as a chain thread to form the row of coupling links Shed to and fro through the weaving level and around one in the area of the attachment point loop-forming mandrel held at one end and tied by means of a weft thread will.

The object of the invention is aimed at improving and simplifying this process for the manufacture of zippers by weaving. According to the invention this is achieved in that the shedding movement of the link-forming warp thread by guiding it around the loop-forming mandrel is produced.

The link-forming warp thread is guided around the loop-forming mandrel two jobs at the same time. On the one hand, the link-forming chain thread is around the loop-forming mandrel wrapped around, causing loops of the warp thread at the weaving point, which lead to formation serve the links of the coupling link row. On the other hand, with this move around already a movement of the link-forming warp thread through the weft insertion plane accomplished to the extent dsr required spreading height of the shed, so that the weft insertion means during the extreme situations of

leadership movement can be effective on the other hand, grasps the link-forming chain thread and binds it into the fabric. During the guiding-around movement, the link-forming chain thread moves with its section located in front of the weft stop parts along the surface of a cone, the cone tip of which lies at the weft stop point and the cone base of which includes the mandrel stop. This cone produced is divided lengthways by the weaving plane into two cone parts, the partial opening angle of which is at least equal to the spreading angle required for weft execution, the loop-shaped lower shed and the other ^M »'J

Known advance of the tissue, the loop in FIG. 1, the chain thread has continuously reached its upper extreme position from the free run-off 15, with the result that the end 33 of the dome is withdrawn. The opposite end 31 15 serving the upper compartment 19 'of the link-forming chain thread for fastening the dome is fully formed. Half a turn later, in the expansion zone for shed formation in FIG. 25, there is the opening in which a chain thread is arranged in dashed lines and is rotatable in position 56 'shown, whereby the glicder-forming of a specially designed mandrel holder is! 32 on chain thread 15 taken its lower extreme position for formation, which has two further functions for the sub-shed 20 '. As can be seen, has beer feet. the chain thread 15 is found in the circulation of the

The mandrel holder 32 consists of an annular rotor disk 47 alternately above and a moderate bearing housing 46, which is used to receive a once below the weaving plane WE, with which the rotor 47 rotates, which has the shape of the Wcbcbenc guided through the needle 17, a flat weft, has circular disc-shaped wheel. The thread 12 can capture the chain thread 15.
The housing 46 in turn consists of a fastening plate 48 which is attached to the frame of the loom between the loom 57 and the 50 on the frame of the loom via one or more fixed supports. Fadcnteilstück 15 'lying to the opening 56 is the formation of a running groove for the rotor disk 47 on the central surface of an oblique Krciskegels, whose in Fig. 2 of the plate 48 a housing ring 49 with an angular dot-dashed cone axis A attached to a profile. Apart from its rotatably movable scits due to the position of the rotor axis 77 and other things, the rotor disk 47 assumes a fixed position with respect to the woven scits due to the location of the loop winding 21 on the plane WE. The Rotorscheibc 47 weaving point 57 is set. The Roiationsebene B is along its circumference with a toothing 51 of the rotor 47 sets the comparable Kcgel-based circuit determines where the view at which the rotary drive is in engagement with a toothed circular orbit of fadenfüh ^r forming Durchrad 52nd The gear 52 is arranged from fraction 56 is located. This base circle closes a shaft 53 driven. If the weaving machine 45 has an acute angle with the ball axis A , there are several workplaces for weaving zips, so that the distance between the rotor disk 47 and loops, which are possibly arranged next to one another with the remaining warp threads 11 of the carrier tape, each of these workplaces is in which borrowed can be kept small to make space to be designed. Wave 53 is going to win. As a result, the thread section 15 'which generates the cone jacket transversely at the individual work points and 50 produces an extremely crooked one which is used to drive the various rotor disc cones, of which FIG. 2 the layers of the generating ben 47th Fadcnteilstücks 15 'by thin dash-dotted lines

The thread run-off point 72 15 is thus on top to form a lower shed, as is also the case for the filler thread 60. If the rotor moves, the mandrel 16 changes its position in the deep fold 70 by half a turn 43 further, the th has reached. The remaining warp threads of the fabric full-thread opening 56 in its diametrically lead a sufficiently large weaving stroke with -bn opposite, dash-dotted drawn spreading positions 11 'and 11, so that position 56', with which the link-forming chain thread 20 compared to them, it does not matter whether the weaving plane 15 its dot-dashed position is in the upper position I or II,
fold. Based on the embodiment of FIG. 5 coordinated rotation 68 of the hollow shaft 69, there is still another possibility, while the unwinding bracket 70 is weaving, during which the unwinding bracket 70 is in the slide-forming movement of the filler thread, inmetrically opposite, dash-dotted lines by inserting the insert 55 in the direction of the dash-dot position 70 , with which the thread run-off point in the arrow 74 drawn in an oscillating position 72 'arrives, so that the accompanying movement can be carried out. The weft thread now needs the carrying needle 17 indicated by dash-dotted lines only in a fixed course. It can thus be seen that one can work over the weaving plane WE I without having to change the height of the rotary device 40 of the filler thread 60 in the addition. Through an unspecified area of the circular cone envelope-shaped swivel drive, the insert 55 oscillates incessant movement of the link-forming chain thread 15, depending on the rotation of the rotor 47, by an angle in this area which it follows with its thread-reaching angular amount, so that over the thread section Between the rotor 47 and the outlet passage 59, the filler thread 60 runs out of its cavity 78 of the shaft 69, because the position shown above the weaving plane WEl, the filler thread describes with that thread part - where it forms an upper shed with it, in a spreading position piece, which is located between the leadthrough, which is located below the weaving plane WE I arranged opening 59 in the insert 55 and the thread run-off point, approximately at the level of the warp threads 72 shown, in turn a conical surface with sliding 11 'or the dome 16. To form such a rather angular velocity. In this round in 40 depths, the insert 55 from FIG. 5 single supply area, the filler thread 60 follows the movements of the glie in a pivoting movement of a little more than 90 ° constant distance.

Instead of the arrangement of the supply as described, the rotor can also be cycled once in one direction of rotation spool the link-forming chain thread 15 and then drive in the opposite direction of rotation. Da-Beilauffadcns 60 could also be reversed with one could easily instead of a coupling arrangement the threads are provided; because it comes with a row of links with helical spring windings generate the compensation of the undesired wraps 50 gen of any other type, z. B. turns in the area of the thread guide only on a spatial meander. This lets itself through a relative rotation between these two threads an alternate drive or suitable on. Couplings in the version shown are slightly

In the embodiment of FIG. 5 is a real one.

converts trained rotor 47 with omission 55 Immediately behind the weaving point 57 is all the other components shown. To designate the one guide 75 for the row of coupling elements, of the corresponding parts, the same reference numerals have been used for heat on the finished row of coupling elements and insofar as the previously practiced for their shaping apply,

One difference is the general meaning in the diameter 60, because it is not only in the larger formation of the insert 55 in the winding wheel. Weaving of the rows of links from zippers-Die Faddurchführungunp, 59 can be used for the filler thread 60 sen, but can now be used far enough from the fastening for each weaving process, where a spreading of the chain end 31 of the dome 60 in the insert 55 can be used for the threads Execution of weft threads in such a way that a spreading angle is achieved that is desirable for a 65. In this way, it would be possible to create the woven carrying path of a weft needle 17 for the intermediate space sufficient for the insertion movement of the warp threads 11. With regard to the bands, corresponding rotors instead of the weaving plane WE I shown in FIG. 5 forms of using web shops. In addition, could

mim with such webfnch-forming rotors the Use warp thread spreading in any other fabric, such as woven tape, in In these cases, the rotor will be used as shown in FIG. 1 with the rotor plane if possible parallel to the plane of the spread position of the Kcltenlaticn arrange. One will mean the axis of rotation Arrange the warp threads lying in a spread position, but purposefully place them in the Attach the middle between the two extreme layers of the shedding. Furthermore, one becomes in these Cases, since no mandrel needs to be held in this position, the eccentricity of the arrangement of the Select the thread-guiding opening 56 with respect to the rotor axis 77 so that it is approximately half the lifting height corresponds to the warp threads. Seen in the illustration of FIG Opening 56 for the movement of an ordinary chain thread from the one shown Spread position II "is transferred to the opposite spread position H 'when half a turn of the rotor has taken place. In these cases, the chain thread is used for the weaving movement

Any desired weave could be created by individually controlling the rotors. For reasons of space, numerous rotors could also be offset next to one another in front of the workplace Arrange shedding To create a clean shed one becomes with increasing enlforming the position of the rotor from the webslellc an increased eccentricity of the thread-guiding opening with respect to the rotor axis. For this one could have openings in the rotor with different Arrange eccentricities. Finally, it would also be possible to use one rotor with several at the same time Provide openings for shedding various warp threads; E.g. the rotor on diametrically to give away opposite places with an opening each for guiding a chain thread .. Im In the latter case, one chain thread is in the upper shed, while the other chain thread is in the lower shed located. After half a revolution of the rotor, the warp threads are reversed to each other.
