Definitions
- the invention relates to a method and an apparatus for winding up warping tapes which, guided by a thread feed arrangement, are wound onto the drum of a warping system in at least two sections arranged side by side.
- warping systems of this type threads are drawn off from a creel, brought together by thread guiding devices and wound onto a drum in so-called warping bands. Depending on the required warp width and number of threads, the winding of the warp band is repeated in several sections.
- each individual tape start is attached to the drum by hand, e.g. knotted and hung in corresponding pictures.
- the tape ends are fixed by hand on the winding surface after cutting.
- the invention has for its object to avoid the known disadvantages, in particular to create a method and an apparatus for winding up warp bands, in which on the one hand a homogeneous structure of the warp beam is ensured and on the other hand the downtimes associated with the application of the bands to the drum System can be reduced to a minimum, as well as minimizing handling for the entire warping process.
- this object is primarily achieved according to the characteristics of the independent claims.
- the fixation of the tape ends provided according to the invention both on the side facing the thread feed arrangement and on the side facing the winding can be achieved in an optimally simple manner both a defined limitation of the winding start and the winding end.
- the warping belt can be optimally easily aligned and / or attached to the drum.
- the attachment can be done, for example, by mechanical clamping devices or preferably by an adhesive tape.
- Flat structures suitable for fixing are in particular adhesive strips or thermoplastic strips which are plasticized by heating to the melting temperature and are thereby connected to the threads.
- Such fabrics are e.g. described in WO 93/19233 or CH-A1-669 303.
- the process can also be automated particularly easily through the use of the flat structures for fixing the strip ends.
- the automation process can be further improved above all if the strip is fixed approximately parallel to the drum by means of a flat structure and if the flat structure is then divided, in particular cut, together with the fixed threads parallel to the drum into two parts. In this way, both the end of the tape facing the drum and the end of the tape feeding arrangement can be fixed in one operation.
- Particularly reliable and durable fixation of the tapes can be achieved if at least two flat structures that can be glued or welded are applied from both sides of the warp tape and the threads are thus fixed.
- the ends of the tape can be fixed particularly easily and reliably on the winding surface if the threads are fixed by two successive flat structures which are attached to the warping tape at a distance from a winding circumference are so that during winding the second of the fabrics lies on the first fabric after a winding revolution and is fastened, preferably glued, to the first fabric.
- the application of the beginning of the warp band to the drum is particularly simplified if the length of the flat structures corresponds to the width of a winding section and if the lateral thread spacing of the threads of the warp band is reduced before the connection to the flat structure, so that the edge threads are securely bound. This allows the fabric to be easily applied next to the previous winding section.
- the fabric can be attached to the drum particularly easily if it is glued to the drum with an adhesive tape.
- a device which has at least one device for applying a flat structure to the warping belt and which also has a separating device for separating the threads and / or the flat structure or the flat structures and which has a manipulator which can be displaced transversely to the drum is particularly suitable for automating the method is provided for applying the fixed threads to the drum.
- at least one heat generating device is provided on the application device. This can e.g. be a heated stamp. Alternatively, it is also conceivable that e.g. a heating wire is provided in the fabric itself, which can be heated by connection to a power source.
- the device can be implemented in a particularly simple and compact manner if the heat generation device and / or the cutting device is also provided on the manipulator. As a result, the heat generating device and the cutting device are also displaced in sections at the same time when the manipulator is moved.
- threads 5 of bobbins 4 are drawn from a creel 3 on a warping system 1 and wound up in sections 8 on a cone drum 9 (FIG. 2) by a cone warping machine 2.
- the threads 5 are given a defined tension by controlled thread brakes 6, are monitored by guards 7 for thread breaks, arranged in a pattern in a cross-hair device 10, brought to the desired thread density by a warping knife 11 and fed to the drum 9 as a warping belt 19.
- the tape is wound up of the warping belt is repeated several times in sections 8, 28, with subsequent windings 28 following the first section 8 according to FIG.
- the band start 12 is to be fastened on the drum 9
- the warping band 19 is separated after the warp length has been reached and the band end 13 (FIG. 4) is fixed on the winding circumference of each section 8, 28.
- all the warp belts are wound together from the drum 9 onto the warp beam 14.
- the warping band 19 is fastened by hand on the drum 9.
- the warping belt can also be automatically applied to the first section 8 in accordance with the procedure described below for the subsequent sections.
- the warping device 11 is displaced in the direction of the reticle device 10 and thus releases the working space between the warping device 11 and the drum 9 for a manipulator 16.
- the manipulator 16 is provided with two belt dispensers 17 and 17a, which bring two thermoplastic strips 18, 18a above and below the warp belt 19.
- the warping band 19 is compressed on both sides in this area to a width which is smaller than the width b of a section 8, 28.
- Now heating jaws 20, 20a are pressed against one another, the thermoplastic strips 18, 18a in between being in the area of two weld seams 21 are plasticized and welded to one another in such a way that the intermediate warping band 19 is fixed.
- a cutting device 22 integrated in the manipulator cuts the welded thermoplastic strips 18, 18a to the width b (FIG. 8), which corresponds approximately to the width b of a section 8, 28.
- the thermoplastic strips are obviously used 18, 18a as a flat structure in order to fix the warping belt 19 in one plane.
- only a thermoplastic strip applied on one side can be used, for example, or special adhesive tapes or other fixing agents in the form of sheet materials can be used.
- a double-sided adhesive tape 24 is applied to the upper thermoplastic strip 18a by means of a second tape dispenser 23 (FIG. 7).
- a separating device 25 By means of a separating device 25, the warping band 19 is cut transversely to the drum 9 approximately in the middle of the thermoplastic strips 18, 18a. As can be seen from FIG. 9, this fixes both the end of the cut warping belt 19 facing the drum 9 and the gate 3.
- the band end 13 facing the warping drum 9 is now glued by a feeder 26 of the manipulator 16 onto the thermoplastic strip 18 attached in the previous operation (FIG. 4).
- the band start 29 facing the creel 3, on the other hand, is held by the manipulator 16 and is moved with it by a warping support 27 (FIG. 5) parallel to the drum 9 into the band application position of the subsequent winding 28 (FIG. 2).
- the beginning of the band 29 is now attached to the warping drum 9 by the feeder 26 of the manipulator 16 according to FIG. 5 by means of adhesive tape 24.
- the guide rods 15 open (FIG. 6)
- the manipulator 16 assumes its rest position and the warping blade 11 goes into the working position.
- thermoplastic strips or adhesive strips Velcro strips, magnetic tapes or other fixable (sewable or rivetable) flat structures can also be used as flat structures.
- the adhesive tape 24 can also be replaced, for example, by a Velcro tape, a magnetic tape or another connecting means, without thereby departing from the scope of the invention.
- Figure 10 shows a modified embodiment in which the warping belt 19 is fixed by two pairs of thermoplastic strips 18, 18a arranged in parallel.
- the separating device 25 cuts the threads of the warp band 19 in the gap between the two pairs of thermoplastic strips 18, 18a.
- FIG. 11 shows a modified exemplary embodiment in which a relatively thick thermoplastic tape 18 is attached only on one side and is connected to the threads 5 by plasticizing.
- the threads 5 are embedded in the plasticized material of the thermoplastic strip 18, if necessary, only selectively.
- the warping process can run practically fully automatically.
- the warping belt is fixed at the belt level, whereby the simultaneous fixing of the belt end and the beginning of the belt particularly simplifies the automation process. Wrapping problems due to knots or irregularities in the thread run in the area of the belt edges are avoided.
- the parallel fixation of all individual threads in the tensioned state prevents irregularities due to loose individual threads or faults due to loose threads on the creel. There are also no loose tape ends on the warp wrap and hanging rails or special fastening devices on the drum circumference are avoided.
