Definitions

  • the invention relates to an air box of an equipment machine.
  • Equipment machines serve to give a textile web the desired dimensional stability by means of a so-called heat setting. For example, first a fabric web of plastic threads may have been produced on a weaving machine, wherein this fabric web is not yet dimensionally stable after weaving. For certain applications of the fabric web, the incomplete dimensional stability may be disadvantageous, for example if the fabric web is sewn into a closed final web and is to be used as a circulating belt in a production machine, for example in the field of papermaking. Dimensional changes in the longitudinal or transverse direction within the production machine can lead to malfunctions.
  • the equipment machine serves to fix the textile material with the help of heat.
  • an elongation of the textile web can be provided in the finishing machine, for example, by the textile web is guided around two pulleys and their distance is gradually increased.
  • the heat treatment of the textile web has two essential aspects: With optimal constellation of heat input into the textile web, a heating process of the plastic material can be completed at about 180 ° already after about 3 s, depending on the materials used for the textile web. However, a subsequent so-called crystallization of the textile plastic material requires a time of about 3 min.
  • the heat treatment in the finishing machine such that the textile web is sewn into a closed loop, is guided around the two variable deflection pulleys and doing several revolutions, so that all areas of the textile web are repeatedly passed through the air box of the finishing machine, where the textile web is heated.
  • a generic air box is for example from the company Alfsen og Gunderson AS, Oslo, Norway under the name "AG Air Through Compact” and from their publication on the Internet using the URL: http://www.ag.no/products-and-services/felt-and-foils/heatsetting-systems/air-through-compact.aspx.
  • Air outlet nozzles and air intake openings are alternately arranged in the upper housing section, and air intake openings are arranged below the upper air outlet nozzles in the lower housing section in a complementary manner and air outlet nozzles are provided in the lower housing section in the reverse direction where air intake openings are located in the upper housing section.
  • the entire interior of the air box housing is used for heating the textile web, which is guided through the housing by virtually the entire length of the textile web, which is located within the housing, to be flowed through by hot air.
  • the invention has for its object to improve a generic air box to the effect that the heat treatment of a textile web can be completed in the shortest possible time and requires as few revolutions of the textile web through the equipment machine.
  • the invention proposes not to use the entire interior of the air box for heating the textile web, but rather to initially provide a heating zone inside the housing and then, downstream of the heating zone in the direction of the textile web, to provide a temperature holding zone in which the Crystallization of the textile tape can be done.
  • the invention is based on the consideration that the textile web, when it leaves the air box, cools quickly to the ambient air, so that only one for the crystallization comparatively short period is available in which the heated textile web still has a sufficiently high temperature level to allow crystallization.
  • a temperature-holding zone be provided within the air box, the textile web is kept in a crystallization temperature range for a relatively long period of time, so that accordingly crystallization can be completed more quickly, ie with fewer turns than before, and thus the efficiency the finishing machine is improved because within a given time a larger number of textile ribbons can be treated.
  • the air box usually extends into the adjustment path of the adjustable deflection roller, so that the minimum distance of the two deflection rollers is determined by the length which the air box has in the web running direction.
  • the invention is further based on the consideration that the heating of the textile web to the desired temperature level is possible even in a shorter heating zone than has hitherto been customary, so that within the housing, the heating zone can be limited to a part of the housing length in the web running direction and therefore the remainder of the housing length is available as a temperature holding zone. Therefore, it can be advantageously provided that the length of the air box in the web running direction must not be greater than in conventional practice air boxes.
  • an air intake opening is arranged within the housing, ie within the temperature-holding zone. While the air outlet nozzles in the tempera- are provided so that there can be intensive heating of the textile web, causes the far back arranged additional air intake that part of the hot air is led together with the textile web through the housing, so that the effect is supported, the Textile web to maintain a temperature level required for the crystallization, while it is in the temperature-holding zone within the housing. It can advantageously be provided that the nozzle openings of the
  • Air outlet nozzles and the air intake openings are each aligned transversely to the surface of the textile web. This promotes an air flow in which the throughflow of air flows transversely to the surface of the textile web and, for example, hits the textile web vertically. Upon impact of the air on the
  • Textile web is always reflected a certain proportion of the air and only a remaining portion of the air passes through the textile web.
  • the respective proportions depend u. a. from the particular embodiment of the textile web, z. B. of the material thickness and the design of the pores in the textile web.
  • another influencing factor is the angle at which the air impinges on the textile web. Accordingly, it can be advantageously provided that the nozzle openings of the air outlets are aligned with the surface of the textile web, so that the outflowing hot air transversely, for example vertically, on the
  • the nozzle openings of the air intake openings are directly opposite the air outlet openings, so that they suck in an air flow which is as perpendicular as possible to the surface of the textile web.
  • the heating effect can be optimized, so that the temperature level of the textile web can be reached as quickly as possible and accordingly a smallest possible first area within the housing of the air box for the temperature heating zone must be provided, so that accordingly a larger proportion of the housing for the temperature-holding zone can be used and accordingly a longer time is available for the crystallization of the textile web.
  • Particularly advantageous may be provided to complete both the upper and the lower housing portion towards the textile web, so that a flat so-called railway tunnel is created through which the textile web runs within the housing namely in the temperature-holding zone.
  • a flat railway tunnel By means of this flat railway tunnel it can be supported that the textile web can be kept in a certain temperature range, namely by having air at the appropriate temperature in the railway tunnel and this air is protected against cooling down by the boundary surfaces of the railway tunnel and reliably held close to the textile web.

  • the running direction of the textile web 2 is indicated by the arrow, thus extending from left to right through the air box 1, wherein this concerns the upper run of the textile web 2, while the lower run correspondingly runs back below the air box 1 from right to left.
  • the air box 1 has an upper housing section 3, which is arranged above the textile web 2, and a lower housing section 4, which is arranged below the textile web 2.

  • the previously discussed compressed air and suction channels 5 and 7 are arranged in a left portion of the air box 1, which is referred to as a temperature-heating zone A.
  • Hot air which emerges from the air outlet nozzles 6 of the lower compressed air channel 5 in the lower housing section 4 and is reflected by the textile web 2, is sucked off on the one hand by the suction channel 7, which is located directly next to the lower compressed air channel 5 within the heating zone A and therefore left from the lower compressed air channel 5 is shown.
  • Reflected hot air which, however, does not flow counter to the web running direction but flows together with the textile web 2 through the temperature holding zone H, is sucked in at the end of the air box 1 by a suction channel 7 provided there, again comparatively small, which is located in the lower housing section 4 is arranged.
