Definitions

  • the invention relates to a textile machine with at least one arrangement that can be moved over the machine production area for feeding at least one thread to the point at which the thread is processed.
  • Textile machines of this type are generally known and are described, for example, in connection with a flat knitting machine in DE-C 36 41 182. These textile machines have the difficulty of processing the thread with constant tension, for example knitting, or inserting it as a final thread, so that uniform, visually appealing textile goods, in particular also with desired product requirements, e.g. uniform stretch properties can be produced. If the tension is not uniform, more or less thread is processed across a textile area, which causes irregularities in the textile goods, so that the product properties such as structure, stretching processes or color impressions are not uniform. This disadvantage occurs in particular when processing elastic or rubber yarn, because different amounts of elastic yarn are processed to a particular degree by a different tension or a different tension on the elastic yarn.
  • the invention is therefore based on the object of providing a textile machine with which uniform textile goods are ensured in a simple manner, in particular also when processing elastic yarns.
  • the object is achieved according to the invention by a thread supply device that can be moved across the machine manufacturing area.
  • the thread to be processed is thus provided directly at the point at which it is processed, without requiring longer paths of the thread, on which the thread can experience a different tension.
  • ERS ⁇ IZBLA ⁇ (RULE 26) can be produced evenly when elastic threads or yarns are processed.
  • the thread supply device comprises a thread tensioning device.
  • a thread braking device is preferably provided which supports the function of always giving the thread a constant tension. In this case, the use of a foumisseur is very advantageous.
  • the thread delivery is regulated so that a constant thread tension is ensured.
  • the textile machine is a flat knitting machine with needle beds and at least one slide movable over the needle beds, the arrangement for feeding at least one thread being a thread guide box which is held and guided on at least one thread guide rail .
  • the arrangement for feeding a thread for example a thread guide box
  • the thread preparation device is moved over the stitch production area independently of the thread guide box.
  • a separate rail is preferably provided for holding and guiding the thread preparation device.
  • the lock slide or its slide bracket is designed so that it optionally takes the thread preparation device with it.
  • the slide bracket has an additional driver device for the thread supply device.
  • An embodiment is particularly advantageous in which the thread guide rails already present are provided for holding and guiding the thread preparation device. As a result, additional rails for guiding and holding the thread supply device are not required. In addition, there are no additional devices for taking the thread supply device because the existing devices for taking the thread guide boxes can also be used for taking the thread supply device.
  • An embodiment in which the thread supply device is coupled to a thread guide box is particularly advantageous. As a result, a driver device for the thread supply device is unnecessary. By taking the thread guide box with it, the thread preparation device is simultaneously moved over the machine production area of the textile machine, in particular the flat knitting machine.
  • Figure 1 shows an embodiment of the textile machine according to the invention in a schematic representation, in which the thread supply device is mounted and guided on a separate, provided rail, and
  • Figure 2 shows an embodiment in a schematic representation, in which the thread preparation device is held and guided on an already existing thread guide rail.
  • the flat knitting machine shown in FIG. 1 has needle beds 1, 2, over which lock slides 3, 4 are moved, which are connected to one another via a slide bracket 5.
  • Thread guide rails 6a, 6b, 6c, 6d are provided for the thread guide boxes, not shown.
  • the thread guide boxes arranged on these thread guide rails 6a, 6b, 6c, 6d can be controlled by thread guide driver devices 7 via driver pins 8 and optionally with
  • the bracket part 11 connecting the two vertical legs of the slide bracket 5 has a driver device 12 for a thread preparation device 13, which is held and guided on a rail 14 provided for this purpose.
  • a driver pin which is controlled and selectively comes out of the driver device 12 into engagement with the thread preparation device 13, couples it to the carriage bracket 5 when it is to be moved over the flat knitting machine.
  • a thread guide arm 15 projects downward from the thread supply device 13 through the intermediate space 10, at the lower end of which a nut 16 is located directly above or between the needle bed intermediate space.
  • the thread supply device is a supplier who receives a thread 17 to be processed from a thread spool (not shown) and this thread is present depending on the tension exerted on the thread to the machine production area - Sends the case to the needle (not shown) of the flat knitting machine. Feeders are available on the market and are not the subject of the present invention, so that their structure and mode of operation need not be explained further.
  • the measure according to the invention of moving the thread supply device 13 over the machine production area ensures a constant thread tension even when the lock slide reverses its direction of movement. This is especially true when processing elastic threads, where it is particularly important to apply a constant tension to the thread regardless of the position of the lock carriage.
  • Figure 2 shows a schematic cross-sectional view with a partial view of the textile machine according to the invention in the form of a flat knitting machine.
  • the thread supply device 13 is held and guided on an already existing thread guide rail 22 provided for thread guide boxes.
  • a thread guide box 23 is provided, which can be moved with the driver pin 8 of a driver device 7 attached to the slide bracket 11 optionally together with the lock slide 3, 4 over the machine production area.
  • the thread guide box 23 is firmly connected to the thread supply device 21, so that the latter is moved together with the thread guide box 23 over the machine production area.
  • the thread supply device 21 can be moved independently of the thread guide 23, be it by means of a further driving pin or by other drive and control devices for displacement across the machine production area.
  • the thread 17 emitted by the thread supply device 21 is guided to the thread guide arm 15 of the thread guide box 23 and from there to the nut 16, from where the thread 17 is then gripped by the needles of the knitting machine or inserted as a final thread.

Abstract

Une machine textile comprend au moins un dispositif (13) conduisant au moins un fil (17) à l'endroit de traitement du fil. Ce dispositif (23) se déplace au-dessus de la zone de travail de la machine. Afin d'obtenir un produit textile ayant une structure (7) et une couleur régulières, même lorsque du fil élastique est traité, un dispositif (13) de mise à disposition du fil est mobile au-dessus de la zone de travail de la machine. L'invention est particulièrement avantageuse dans une machine à tricoter rectiligne.
