Definitions

  • the invention relates to a weaving machine according to the preamble of claim 1.
  • the compact design makes access and operation difficult and is also susceptible to dirt due to the round bar of a clamping spreader inserted in a narrow, almost closed groove, since the fabric web is pulled through this groove and clamped at the entry and exit slots and this removes fluff and winds up loose threads.
  • Another significant disadvantage is that the disadvantageous shrinkage behavior and the encrusted strip separating edges cannot be eliminated with a heating wire arranged on one side above or below the strips.
  • the compact design does not permit any other solution, which means that the disadvantages mentioned have not yet been eliminated with this solution and the strip quality required by the market cannot yet be achieved.
  • a device is known from US-PS 4 1 4 420 which cuts a wide fabric into ribbons.
  • the device is an independent unit, which is modeled on a breast tree of a weaving machine and consists of a multiplicity of deflection rollers and a dancer device for maintaining a constant belt tension and belt speed on the cutting device.
  • This device has the disadvantage that the long path of the fabric web impairs the guidance, so that an exact pattern-accurate separation of the fabric web into individual tapes is not guaranteed.
  • the object of the invention is to improve a loom of the type mentioned.
  • the object is achieved according to the invention by the characterizing features of claim 1.
  • these individual devices can be individually optimally configured due to their detached arrangement, for example on the machine frame. Nevertheless, due to the close arrangement of the cutting device on the guide device and thus on the weft thread edge, optimal guidance of the fabric web and thus pattern-accurate cutting is achieved.
  • the fixation device connected downstream of the breast tree enables optimal fixation conditions, the guidance of the individual ligaments no longer being critical.
  • the weaving machine can have a deflecting rod system according to claim 15, but a hold-down device according to claim 2 is more advantageous.
  • the fabric web is only S-shaped around two guide edges by two guide strips, the resistance of the fabric web in the guide device is relatively low, so that the fabric web can be guided through the guide device in both directions. This results in a particularly simple construction of the guide device is practically not susceptible to dust and is easily accessible for maintenance and adjustment work. Nevertheless, the S-shaped guidance of the fabric web offers sufficient hold-down and guidance of the fabric web on the weft thread flange edge and a smooth, smooth guidance for the cutting process, so that optimal manufacturing conditions are provided for the fabric web or the tapes are.
  • the embodiment according to claim 3 enables a good adaptation of the guide bar to the fabric web and the embodiment according to claim 4 enables a particularly subtle adjustment of the guide device, in particular to the type of fabric web to be produced, for example its thickness.
  • the first guiding strip can be arranged in such a way that the fabric web lies against this guiding strip from below, so that the groove-shaped recess and the second guiding strip then lie above the first guide strip it is more advantageous, however, if the fabric web rests on the first guide bar and is guided downward into the groove-shaped recess, into which the second guide bar " pointing counter to the direction of travel of the fabric web also engages.
  • Adapting the second guide bar with its second leading edge on the type of fabric web and the production conditions can be improved by a configuration according to claim 6 or 7.
  • the configuration according to claim 8 also has the same effect, whereby any jamming of the fabric web on the guide device is adjustable .
  • An embodiment according to claim 9 is particularly expedient, since the fabric web produced can then be subjected to a first fixation by means of the heating device.
  • An embodiment according to claim 10 and / or 11 can be expedient in order to bring the tissue into a desired shape.
  • a heating device provided on the leading edge and / or on the spreader bar can enable the aligned fabric web to be fixed.
  • the alignment of the fabric web on the spreader bar can be further promoted by the known design according to claim 12. It is also possible for the spreader bar to be arranged in a fixed manner. But also a ange ⁇ exaggerated Off 'gesta Itungnach claim 14 is possible.
  • a design of the cutting device according to claim 16 is particularly advantageous.
  • the adjusting device makes it possible to adapt the cutting process to the weaving process, ie to the repeat length of a weaving pattern in the fabric web. So the Webge ⁇ example speed in label weaving and therefore the take-off speed • during weaving the pattern slower than in the area between the patterns.
  • the adjusting device now makes it possible to set the cutting heads along the fabric web in such a position that they always cut an unpatterned area when the weaving speed and thus also the take-off speed is greater than in the patterned area.
  • a fixing device which enables the strips produced to be properly fixed without substantial changes in shape.
  • the fact that the belts rest on the rough surface of the roller prevents warping of the belts in the longitudinal and transverse directions. Maintaining the form Faithfulness is supported by the installation of the heating shoe.
  • the rough surface of the roller can be achieved, for example, by adhering granular material, such as corundum powder, metal powder and the like.
  • a design according to Aasprr ⁇ ch 18 is particularly advantageous, since the sprayed-on and melted-on metal puLv.er forms an intimate connection with the surface and. is therefore not influenced by the heating caused by the heating shoe. Particularly good results are obtained with a configuration according to claims 19 and / or 20. Training according to claim 22 is also particularly expedient.
  • An embodiment according to claim 22 is particularly advantageous, since the preheated roller facilitates fixation, in particular in the case of tendon 11 runners.

  • Cutting heads with ultrasonic cutting elements or laser cutting elements are also possible.
  • the cutting elements are designed in such a way that they do not only cut the fabric web, ie practically cut them through enable the weft threads between two warp threads, but at the same time also ensure that the cutting edges melt open.
  • the fabric web consists at least partially of thermoplastic yarns.
  • the cutting heads (20) are connected to a support (28) via adjusting spindles (26) and can thus be adjusted in their position in the direction of the warp threads, ie in the running direction of the fabric web. This makes it possible to synchronize the cutting process with the pattern repeat of the fabric web.

Abstract

Métier à tisser comprenant un dispositif de guidage (12b) pour bande de tissu (10), un dispositif de coupe (18) disposé entre le dispositif de guidage (12b) et une ensouple de devant (40), suivie d'un dispositif de fixation (18). Tous les agrégats sont montés séparément sur le métier à tisser. Ce montage séparé facilite beaucoup l'accès à chaque agrégat pour effectuer les réglages et réparation et les têtes de coupe (20) du dispositif de coupe (18) peuvent être réglées dans le sens de la chaîne. La coupe peut ainsi être synchronisée avec une répétition de dessin. La bande de tissu est néanmoins guidée avec précision pour assurer une coupe répondant précisément au dessin.
