Definitions

• Method for producing a fabric web in particular a tape fabric r with a velvet edge, and device for carrying out the method.
• the invention relates to a method for producing a fabric web, in particular a tape fabric, with a velvet edge according to the preamble of claim 1 and a device for carrying out the method according to the preamble of claim 8.
• a method and a device of the aforementioned type are known from EP 0 546 485A. There, it is described that a wide fabric web produced on a loom is cut into individual ribbons, with warp threads adjacent to the cutting edge being pulled out and removed after cutting. The exposed ends of the weft threads then form the fringes of a velvet edge.
• a take-off device which is arranged above the fabric web and includes a rotating tube through which the warp threads to be deducted are to pass. By frictional contact the withdrawn warp threads are twisted together in the manner of a rope and fed to a corresponding take-off device.
• the object of the invention is to improve a method for producing a fabric web, in particular a tape fabric, with a velvet edge and a device for carrying out the method. This object is achieved according to the invention:
• the device for carrying out the method is extremely simple and effective, since it only requires the arrangement of a deflection member that is arranged downstream of the cutting tool on the device.
• the velvet edge can be further improved if, according to claim 3, in the fabric web, the seam edge region to the fabric web is arranged to be delimited by melting threads whose melting temperature is less than a possible melting temperature of the remaining threads of the fabric web.
• the cutting tool can be used according to claim 4, which is heated to the temperature of the melt warp threads, or according to claim 5, the deflection member which is heated to a corresponding temperature.
• adhesive threads in the fabric web according to claim 6, which limit the velvet edge region to the fabric web.
• the deflection members are arranged in such a way that at least one normal warp thread is arranged between the deflection member and the fusion warp thread on the one hand or a glue warp thread on the other hand.
• the velvet edge can be further solidified without the deflecting member and / or the fringes of the velvet edge becoming dirty or even sticking together.
• the cutting of the weft threads can take place thermally by means of melting through or burning through. However, this usually does not provide perfect ends of the fringes.
• the cutting preferably takes place mechanically, for example by means of a cutting knife or scissors, in order to obtain perfect ends of the fringes.
• Claims 9 to 13 describe various apparatus features to realize the method variants discussed above.
• the device for carrying out the method can be independent of a weaving machine, wherein the fabric web feeding device can consist of a roll, to which the fabric web is wound up. It is advantageous However, if the device is integrated according to claim 14 in a weaving machine, wherein it is arranged downstream of the weaving.
• FIG. 1 shows an apparatus for producing a fabric web, in particular one
• Tape fabric with a velvet edge, in side view; 2 shows the device of Figure 1 in detail and on a larger scale, as well as in plan view.
• FIG. 1 shows a device 2 for producing a fabric web 4 with a velvet edge 6. It contains a fabric web delivery device 8, which is formed in the present example as a known weaving machine. At a weaving location 10, a fabric web 4 is produced, which is pulled off at a fabric take-off 14.
• the weaving site 10 is followed by a cutting tool 16, which may be designed, for example, as a stationary or rotating cutting blade or possibly as a pair of scissors.
• the cutting tool 16 cuts through weft threads 18 in the direction of the warp threads 20 so that the fabric web 4 is divided into two fabric webs 4a, 4b.
• deflecting members 22, 24 are arranged, in such a lateral distance to the cutting tool 16, which corresponds to the warp threads 20 a, which are to be removed from the fabric web to form the velvet edge 6.
• the deflecting members 22, 24 provide for an orderly stripping of the warp threads 20a, so that a uniform velvet edge 6 is formed without loosening the remaining warp threads 20.
• the deflection members 22, 24 even cause a depression and thus compression of the remaining warp threads against the fabric web and thus a solidification of the velvet edge 6 and thus increase the durability of the velvet edge 6.
• the warp threads 20a to be removed are removed on both sides by means of draw-off devices 26, 28.
• the fabric web 4 contains melt warp threads 20b whose melting temperature is less than the melting temperature of the remaining threads of the fabric web.
• the melt warp yarns 20b are preferably activated by means of the deflector members 22,24 which are heatable to a temperature which corresponds to the melting temperature of the melt warp yarns 20b.
• at least one normal warp thread 20 is arranged between the deflecting members 22, 24 and the melt warp threads 20b. This results in a uniform velvet edge 6, in which the fringes 30 have the same length everywhere, and which is characterized by particularly good stability and fatigue strength.
• melt warp threads 20b instead of the melt warp threads 20b, it is also conceivable to use adhesive warp threads.
• the device is characterized by a particularly simple structure, since the deflection members 22, 24 are arranged stationary so do not require a drive.
• the device can also be designed in such a way that a plurality of tape webs having velvet edges on both sides are produced from a wide web of fabric, as is known from EP 0 546 485.
