Definitions

  • the invention relates to a device for producing a heat and tensile, and flexible connection between the ends of a layer of a plurality of parallel yarns (yarn layer) and a web-shaped material with a first holding device for temporarily clamping the free end of the wound on a storage drum and from this removable web-like material, the holding device being arranged to the side of the transport plane of the yarn layer and, viewed in the transport direction of the yarn layer, a clamping device for the yarn layer is arranged behind this holding device, between whose mutually movable jaws the transport plane of the yarn layer runs.
  • yarn layer means a fibrous two-dimensional material, the thickness of which is only of very low value in comparison with the width and in particular the length.
  • these are textile webs in the form of non-woven fabrics such as nonwovens, or also single-layer and multi-layer parallel thread sheets, for example, end or warp yarns.
  • Textile processing methods which are carried out in elongated plants are washing, singeing, bleaching, dressing, printing, finishing and the like. Threads are usually dyed and sized.
  • the layer of a plurality of parallel yarns is held in the stretched state, namely between a first strip of a weldable or heat-sealable plastic that is attached to a fabric and a second weldable or heat-sealable strip, whereby the planes of both strips and the yarn layer run essentially parallel to one another. Then the strips and the yarn layer are pressed together and the two strips are connected to one another by heat welding or sealing, the yarn layer being clamped between the strips by this sealing or welding, so to speak.
  • the invention aims to design a device of the type mentioned at the outset in such a way that the use and use of such very necessary and very expensive weldable and heat-sealable substances can be dispensed with.

  • a needle head in the sense of this description means a mechanical device with at least one reciprocating sewing needle that guides an upper thread, as is known in sewing machines.
  • a boat head is understood to mean a mechanical device in the sense of this invention, which has boats or grippers which guide a lower thread and which cooperate with the needle of the needle head in order to create a seam formed from at least two threads.
  • the device according to FIG. 1 represents a first exemplary embodiment of the invention and is arranged in a stationary manner on the inlet side of a yarn treatment plant, of which only the so-called compensator 20 is shown here.
  • the horizontally running transport plane E is represented by a yarn layer 2 passing through the device in the sense of the above explanations, which lies approximately halfway up the device.
  • the direction of transport in which the garrilage 2 passes through the system and device is indicated by an arrow 3.
  • rail-like guides 4 and 5 are provided in the machine frame 1.
  • a needle head 6 is slidably mounted, which carries two needles 7 and 8 here.
  • needles 7 and 8 are, as shown in FIG. 1, offset from one another in the transport direction (arrow 3). In operational use, this needle head moves perpendicular to the plane of the drawing in Fig. 1.
  • a machine head 9 - hereinafter the shuttle head - is slidably mounted, in which shuttle or gripper mechanisms are arranged.
  • the needles 7 and 8 guide the upper thread, the shuttle or looper a lower thread.
  • a needle head is understood to mean a mechanism such as that used in sewing machines is known.
  • the needles can be moved in their axial direction and have an eyelet near their pointed end through which the so-called upper thread is looped.
  • the shuttle head is understood to mean a mechanical device in which shuttle or hook are mounted, which guide a lower thread and which cooperate with the reciprocating needle in a conventional manner to form a stitch.
  • the two machine heads 6 and 9 are connected to one another via a U-shaped yoke 10 (FIG. 2), the depth of which is greater than the width of the yarn layer 2 to be treated.
  • the plane of the yoke 10 is at right angles to the plane of the drawing in FIG 1 or is parallel to the drawing plane in Fig. 2.
  • a drive motor 11 for the sewing needles 7 and 8 and the shuttle head is expediently flanged directly to this yoke 10 and the drive elements for the synchronous drive of needle and shuttle run expediently in the hollow boxes trained legs of this yoke 10.
  • the section connecting the two legs of the yoke 10 is, as shown in FIG. 2, supported against the floor 12 by a strut 13 with a roller 14 which is expediently guided along a guide track.
  • the working direction of the yoke 10 is indicated by an arrow 15 in FIG. 2.
  • the shuttle head 9 is also penetrated by a stationary but rotatable threaded spindle 16 which can be driven by a stationary motor 17.
  • the rotating spindle 16 moves the yoke 10 and with it the needle head 6 and the shuttle head 9 synchronously and at right angles to the drawing plane according to FIG. 1.
  • a first holding device 18 is arranged, which is formed from two mutually adjustable strip-shaped clamping jaws 21 and 22, the adjustment device for these two jaws 21 and 22 are not shown here in FIG. 1. Hydraulically or pneumatically actuable piston-cylinder units can expediently be used as the adjusting device.
  • this holding device 18 is arranged in such a way that its support plane for the sheet-like or layered material 19 is at approximately the same level as the support plane 23 of the shuttle head 9, in front of which, also in the direction of transport (arrow 3), and below the transport plane E a freely rotatable deflection roller 24 is mounted in the machine frame 1.
  • a carriage 25 In front of the machine frame 2 of the device and also below the transport path E, a carriage 25 is mounted at right angles to the plane of the drawing according to FIG. 1 and carries a supply roll 26 on which the web or layered material 19 is wound.
  • a second holding device which consists of two pairs of terminal strips 27 and 28. These two pairs 27 and 28 are arranged so that the imaginary displacement plane of the needle head 6 lies between them, in other words, the two pairs of terminal strips 27 and 28 lie on different sides of the needle head 6 and also extend at right angles to the plane of the drawing according to FIG. 1 Adjustment devices 29 and 30 are also provided for these pairs of terminal strips, which, however, are not shown in FIG. 1 for reasons of clarity.
  • One strip of each of the two pairs of clamping strips 27 and 28 is connected at the end to a cross member 31 and these parts together form a frame 44 which can be raised and lowered along vertical guides 32 by means of an adjusting device 33.
  • These vertical guides 32 are parts of a carriage 34 which, in turn, is horizontally displaceable horizontally along a guide 35 which is stationary with respect to the machine frame 1.
  • a piston-cylinder unit also serves as the adjusting device 36.
  • a clamping device 37 On the side of the machine frame that faces the yarn treatment system, a clamping device 37 is also provided, through the two clamping jaws of which the transport plane E or the yarn layer 2 runs.
  • a piston-cylinder unit 38 also serves to actuate this clamping device.
  • a cutting bar 39 Opposite it, on the input side of the device or machine frame 1, there is also a cutting bar 39, the actuating device of which is not shown here. So much for the construction of the device.
  • a parallel group of threads or yarn here referred to as yarn layer 2
  • yarn layer 2 runs from not shown paper trees and runs from the left (FIG. 1) into the device, through it and then over one first deflection roller 40 into the actual yarn treatment plant with the upstream compensator 20, where it is subjected to the actual processing operations one after the other.
  • the yarn layer 2 passes through the parts explained above, the interaction of which will now be explained below. It is anticipated that Fig. 1 shows these parts in their respective position, which they assume during normal work flow, ie the cutting bar 39 and the clamping device 37 are open, the pairs of clamping bars 27 and 28 are raised, as are the needles 7 and 8 the needle head 6 and the drive motor 17 is stationary.
  • a fabric web is wound on the supply roll 26 and a piece of this fabric web 19 is pulled off, guided over the deflection roller 24 and the shuttle head 9 and the free end is clamped in the first holding device 18.
  • This web of fabric 19 is taut, since it does not come from the supply roll 26 against the action of one arranged there the trigger brake shown is removed.
  • a fabric strip 41 is held and tensioned by the two pairs of terminal strips 27 and 28, which, as can be seen in FIG. 1, lies above the yarn layer 2 or the transport plane E. This arrangement concerns and shows the device when the yarn layer 2 passes through the treatment plant properly and there is still a sufficient supply of yarn on the slip trees (not shown).
  • the drive motor 11 for the sewing device is briefly stopped when the needles are pulled up and by means of the adjusting device 36 ( Fig. 3) the closed and pressed against each other terminal block pairs and pressure strips 18, 27, 28, 42 a little to the right and then the drive motors 11 and 17 are switched on again, whereupon the yoke 10 returns to its initial position shown in FIG. 3, at the same time again two seams are made.
  • the motors 11 and 17 are switched off.
  • the needles 7 and 8 raised, the clamping devices 18, 27 and 28 opened and moved apart and the yarn layer 2 itself cut by actuating the cutting bar 39 and then the clamping device 37 opened.
  • the pulling force acting from the yarn treatment plant now pulls the substance 19 off the supply roll 26 via the yarn layer 2 still running in this treatment plant.
  • this substance 19 has only the task of serving as a production aid and it can be used and used repeatedly.
  • a normal simple fabric can be used, which is formed from warp and weft threads, but other materials are also conceivable, for example layer materials, such as plastic films or the like.
  • FIG. 5 shows a connection between the material 19, the fabric strip 41 and the yarn layer 2 in an oblique view.
  • the four seams here are offset against each other. As tensile tests with connections made in this way show, these are extremely resilient.
  • This connection as described above and illustrated in Fig. 5, consists of the four staggered seams mentioned and the two fabrics 19 and 41, between which the yarn layer 2 is held. It is now possible to repeatedly put the sewing device with the heads 6 and 9 into operation during the establishment of a connection, so that not only four but, for example, eight seams are produced. It is also possible to arrange more than two needles in the needle head, so that more than two seams can be produced at the same time in one run of the sewing device.
  • the upper fabric strip 41 takes on two tasks in this connection, first it serves as the actual connecting element and it also serves to enable the hold-down device, which is assigned to each needle, to slide freely over the material to be sewn. If the demands on the tensile strength of the connection are not too great, it is entirely conceivable to omit the upper strip 41, for example, when making this connection. So that sewing can be carried out without difficulty in this case, it is provided that the holding-down device cooperating with the sewing needle of the needle head 6 (see FIG. 6) is designed as a freely rotatable disc 45, the axis of rotation 46 of which is parallel to the direction of transport (arrow 3) of the thread layer 2 lies.
  • the needle head 6 and the shuttle head 9 are mechanically connected to one another via a yoke 10.
  • this yoke 10 migrates sideways. A corresponding place in the machine hall must be provided for this.
  • the needle head 6 and the shuttle head 9 are also possible to use the needle head 6 and the shuttle head 9 as independent and mechanically separate units, that is to say without the yoke 10 connecting them. Due to the modern electronic control and regulation devices available today, an exact synchronous running of these spatially separated components can also be achieved independently of such a mechanical connection via a yoke 10.
  • FIG. 7 now illustrate a second exemplary embodiment of the invention, which has a simplified mechanical structure compared to the first described exemplary embodiment.
  • the same reference numerals have been used to designate the same parts in both exemplary embodiments.
  • the device according to FIG. 7 is also arranged in a stationary manner on the inlet side of a yarn treatment plant, of which only the so-called compensator 20 is shown here, however.
  • the angularly extending transport plane E is represented by a yarn layer 2 passing through the device in the sense of the above explanations.
  • the direction of transport in which the yarn layer 2 passes through the system and device is indicated by an arrow 3.
  • the yarn layer 2 runs towards the machine frame 1 at about half the height thereof and is deflected vertically downwards by a freely rotatable deflection roller 5.
  • a freely rotatable deflection roller 5 In the bottom area of the machine frame 1, further deflection rollers 51 and 52 are provided, via which the yarn layer 2 is fed to the compensator 20.
  • the deflecting roller 51 is not fixed in place in the bottom region of the machine frame 1, but rather this deflecting roller is vertically adjustable.

  • a support 53 is slidably mounted and at right angles to the plane of the drawing, a stationary but rotatably mounted threaded spindle 16, which is parallel to the rail-like guides 4 and 5, is used for this displacement, which is shown by a motor shown in simplified form 17 can be driven in both directions of rotation, so that this support 53 can be moved both into the drawing plane and out of this drawing plane.
  • This support 53 carries a sewing device 54 with a needle head 6 and a shuttle head 9, both of which are connected to one another via a relatively short yoke 10, the drive mechanism for the needle and the shuttle or, respectively, in this yoke 10, as is usual with sewing devices of this type the gripper is housed.
  • a motor 11 flanged to the yoke 10 is used to drive this mechanism.
  • the needle head 6 carries two needles 7 and 8, which have different distances from the transport plane E and which are also offset from one another at right angles to the plane of the drawing.
  • the needles 7 and 8 guide the upper thread, the shuttle or looper a lower thread.
  • a needle head in the sense of the present invention is understood to mean a mechanism as is known from sewing machines. The needles can be moved in their axial direction and have an eyelet near their pointed end through which the so-called upper thread is looped.
  • the shuttle head is understood to mean a mechanical device in which shuttle or gripper are mounted, which guide a lower thread and which cooperate with the reciprocating needle to form a stitch in the conventional manner.

  • One roller 61 is above and the other roller 62 is below the imaginary sewing plane, which is perpendicular to the working direction of the sewing needles 7 and 8, which is to be thought of as the horizontal plane at right angles to the plane of the drawing in the embodiment of FIG. 7.
  • the two rollers 61 and 62 which lie one above the other, are spaced apart from one another, but are adjustable relative to one another in the plane containing their axes in order to reduce their mutual distance. The mechanics used for this are not shown here for reasons of clarity.
  • the adjustment of a roller can be achieved, for example, in that the shaft or axis of the roller are freely rotatably supported at their outer ends in bearing blocks, and these bearing blocks are mounted so as to be vertically displaceable along the machine frame, a lifting cylinder being used for this displacement one end is attached to the machine frame and the other end to the bearing block.
