Definitions

  • the invention relates to a device for continuous and tension-free treatment, such as drying, shrinking, finishing, etc., of textile webs which are stretched or compressed in at least one treatment zone by air blows directed against the web from underneath over the entire web width, comprising a conveyor belt, on which the web is conveyed from treatment zone to treatment zone, at least one sub-nozzle, which extends transversely to the transport direction and is arranged below the conveyor belt and connected to a compressed air source, at least one closing means for opening and closing the sub-nozzle, and arranged above the sub-nozzle, transversely Partitions extending to the direction of transport, delimiting the treatment zone, the sub-nozzle being inclined in the direction of transport by a few angular degrees with respect to the vertical, a perforated plate extending transversely to the direction of transport being inserted between the partitions, the spacing thereof being too m
  • the conveyor belt increases in the direction of transport, and the maximum distance between the conveyor belt and perforated plate is between 5 and 15 cm.
  • a device for the continuous treatment of textile webs is known, for example, from DE-PS 26 44 309.
  • the web is shot up under the influence of pulsed air jets, with only the lateral spread being limited by two partitions, however, the amount is essentially unlimited.
  • tensile stresses are built up in the material web, which are not completely eliminated in the subsequent folding after the air blast has been switched off.
  • the shrinkage achievable in this machine is completely inadequate.
  • a significantly improved version of this patented device is commercially available.
  • the improvement is that the sub-nozzle is inclined in the transport direction by approximately 15 ° with respect to the vertical, that a perforated plate extending transversely to the transport direction is inserted between the partition walls, the distance to the conveyor belt increases in the transport direction and that the maximum distance between the conveyor belt and perforated sheet is approx. 11 cm.
  • the main advantage of these improvements is that the shot height of the web is limited, so that no tensile stress can build up and that the web strikes hard against perforated plate or partition, whereby the tensions in the web are relaxed.
  • the present invention is therefore based on the object of further developing the above-mentioned device in such a way that webs that are warped or have different shrinking properties can be treated.
  • the pressure of the air supplied to the sub-nozzles must have a value which is as precisely defined as possible so that the air blows emerging from the sub-nozzles are directed perpendicularly. If the air pressure is too low, the air blows are inclined towards the tip of the sub-nozzles; if the air pressure is too high, the air blows are inclined away from the tip of the nozzle. In both cases the web warps.
  • the sub-nozzle can be pivoted about the vertical axis and, according to an advantageous development of the invention, the chicane can be tilted about the longitudinal axis.
  • upper nozzles can be arranged above the perforated sheets, which blow a continuous air flow which is controllable in terms of its strength downwards, due to the perforated sheet perforation and inclined position, preferably obliquely downward in the transport direction.
  • These top nozzles ensure that the top of the web is also dried. They also create an air cushion so that the goods no longer hit the metal of the chicane extremely hard.
  • the air of the upper nozzles when correctly aligned and strong, reinforces the S-stroke already described, which further increases the shrinkage, cleanly clean the top of the perforated plates of the chicane and improve the straightening effect on warped webs.
  • the upper nozzle can emit air blasts counter-emitting to the lower nozzle.
  • the frequency of the air blows generated by the sub-nozzle is preferably 1 to 8, preferably 1 to 5 Hz.
  • the number of air blasts per unit of time improves the shrinking effect of the entire device.
  • Fig. 1 you can see a continuously running, endless conveyor belt 1, on which a web 2 loosely gathered is transported from left to right through the device.
  • Several treatment zones are provided in the device, each treatment zone consisting of a lower nozzle 3 with a nozzle opening 4 and a closing element 5, two partition walls 7 above the lower nozzle 3 and a perforated plate 8 which extends transversely to the direction of transport and whose distance from the conveyor belt 1 is in Direction of transport seen increased.
  • an air blast shoots up the part 6 of the web 2 above it, an S-shaped flap being formed before the web 6 reaches the perforated plate 8 and partition 7 formed chicane strikes.
  • the closing member 5 closes the nozzle opening 4 again, the S-shaped part 6 of the web 2 collapses again and is transported to the next treatment zone.
  • the slides shown as closing elements 5 are connected to one another and are actuated by a common drive, not shown.
  • the arrangement is such that in the end positions of the slide 5 only one of two adjacent sub-nozzles 3 is released and that in the intermediate position of the slide all sub-nozzles are closed at the same time. If this condition is not met, there is a continuous wave formation in the web 2, whereby this is shot directly to the exit of the device.
  • FIG. 1 Above the perforated plates 8, upper nozzles 9 with nozzle openings 10 can be seen in FIG. 1, which are likewise closed and released by closing members, for example slides 11.
  • the control of the slider 11 is counter-emitting to the control of the slider 5. It is essential that the air blows emerging from the upper nozzles 9 reinforce, among other things, the S-shaped flap of the web 2, as represented by reference numeral 6 '. In addition, with the help of the upper nozzles 9, an air cushion can be built up in the area of the perforated plate 8, thereby preventing the web 6 from striking the perforated plate too hard. Finally, with the help of the upper nozzles 9, the top of the perforated plates 8 is blown free of fluff. Together with the rest of the air, these fluffs reach the fluff filters that are usually already present in the base of the device.
  • a longitudinal axis 12 can be seen in FIG. 1.
  • the entire chicane consisting of dividing walls 7, perforated plates 8, upper nozzles 9, nozzle openings 10 and slides 11, can be tilted about this longitudinal axis 12 in order to avoid influences which favor warping of the material web, to be able to compensate.
  • FIG. 2 shows a perspective view of the device of FIG. 1, the chicane being shown partially removed and partially broken open.
  • the nozzle opening 4 of the sub-nozzles 3 are inclined by approximately 7.5 ° with respect to the vertical in the direction of transport, the highest distance between the conveyor belt 1 and perforated plate 8 being approximately 13 cm. In general, it can be said that the distance must be chosen the smaller, the more inclined the sub-nozzles 3 are angled.
