Definitions

  • the invention relates to a device for supporting and guiding material tape to be processed, especially nylon or steel cord tapes, in the range of a continuous or discontinuous feed or Removal of the material strip by means of appropriate conveying devices depends on the discontinuous supply or removal in their hanging position changing loop of the material band.
  • DE 44 11 936 C2 already contains a Support conveyor belt has been proposed, which is the actual one Material band in the loop area, at least in the area of the loop depression, wearing a support loop.
  • the support conveyor belt is driven so that the conveyor belt loop is synchronized with the material loop changes and therefore the material band loop in any position the support conveyor belt loop is supported.
  • the invention is therefore based on the object of a device at the outset mentioned type so that with simple means irreversible changes the length and / or width of the material band can be avoided.
  • the invention provides that the material band over, dividing the loop into two partial loops, continuously with the Removal device, rotatingly driven calming rollers, in particular in the form of a large diameter calming drum, preferably above 350 mm, is guided.
  • the inventive design forms between the feed device the calming drum is one in length corresponding to the most discontinuous feed changing loop, within which actually Elongations of the material band occur.
  • the one between the calming drum and the calming loop of constant length lying on the removal device surprisingly, however, leads to these elongations being complete or at least largely regress, so that on the removal device the material band is again in the form as it is from the feed device is delivered.
  • the calming rollers form the deflection rollers of a conveyor belt section, i.e. between the The supply loop and the calming loop is an essentially horizontal one Conveyor belt section switched on.
  • the calming drum and the removal device lying calming loop should be designed only briefly, so only a little sag, and moreover, the calming drum should be closer to the removal device than be arranged in the feed device.
  • this relatively small calming loop its weight is correspondingly small, so that here not only no unwanted elongations due to high weight the loop can occur, on the contrary, even the above mentioned regression of the elongations between the feeder and the calming drum has occurred can take place.
  • FIG. 1 shows a splicing device 1, of which the spliced material strip 2, for example a nylon or steel cord belt, via a conveyor belt Feeder 3 normally via a hanging loop 4 above a pit 5 is passed to a removal device 6, which, likewise prefers . designed as a conveyor belt, is continuously driven.
  • a removal device 6 which, likewise prefers . designed as a conveyor belt
  • a calming drum according to the invention 7 provided over which the material band 2 is guided and thereby in two part loops, namely the supply loop 8 and a calming loop 9, is divided.
  • the storage loop 8 changes its length in the same way as this was the case with the conventional one-piece loop 4 during the length the calming loop 9 remains the same since the calming drum 7 has the same Continuous speed is driven like the removal device 6.
  • the calming drum with its drive device 10 is the beginning the removal device 6 spaced closer than the end of the feed device 3. As a result, a large supply loop 8 can form and on the other hand, there is only a relatively small calming loop 9.
  • Diameter of the calming stream 7 is affected can be, which consequently have a minimum diameter of about 350 mm should.
  • FIG. 2 only differs from that according to FIG. 1 characterized in that instead of a calming drum 7 two the pulleys one Conveyor belt 11 calming rollers 12 are provided.
  • the storage loop 8 and the calming loop 9 are therefore not one Drum separated, but in principle a conveyor belt section of any length.

Claims (6)

  1. Dispositif pour supporter et guider une bande de matériau à traiter, notamment des bandes de Nylon ou de fils métalliques, dans la région d'une boucle de la bande de matériau, boucle qui provient du transport continu ou intermittent d'amenée ou d'évacuation de la bande de matériau, au moyen de transporteurs correspondants, et dont le positionnement en suspension se modifie en fonction du transport intermittent d'amenée ou d'évacuation, caractérisé en ce que la bande de matériau (2) est guidée par l'intermédiaire de rouleaux de stabilisation subdivisant la boucle en deux boucles partielles (8, 9), entraínés en rotation de façon continue avec l'appareil transporteur d'évacuation.
  2. Dispositif selon la revendication 1, caractérisé en ce que les rouleaux de stabilisation se présentent sous la forme d'un cylindre de stabilisation (7) de grand diamètre.
  3. Dispositif selon la revendication 2, caractérisé en ce que le diamètre du cylindre de stabilisation (7) est supérieur à 350 mm.
  4. Dispositif selon la revendication 1, caractérisé en ce que les rouleaux de stabilisation (12) forment les rouleaux de renvoi d'une bande transporteuse (11).
  5. Dispositif selon l'une des revendications 1 à 4, caractérisé en ce qu'entre le cylindre de stabilisation (7) et l'appareil transporteur d'évacuation (6) n'est formée qu'une courte boucle de stabilisation (9) de longueur constante, qui pend sur une faible hauteur.
  6. Dispositif selon l'une des revendications 1 à 5, caractérisé en ce que le cylindre de stabilisation (7) est disposé plus près de l'appareil transporteur d'évacuation (6) que de l'appareil d'amenée (3).
