Definitions

  • the present nvention relates to an improved apparatus for continuously decatizing fabrics on a cylinder ith local steam generation.
  • a method of continuous decatizing is known, as well as the relevant apparatus, for a dimensional conditioning of fabrics by causing them to pass about a very hot rotating steel cylinder, e.g. at a tempera- ture of 160-180°C.
  • From DE-A-3.412.982 it is known to feed the previously damp or wet fabric between said heated cylinder and a water-proof endless (ring-shaped) web or back cloth which is moved forward at the same speed as the hot cyLinder and subjected to a great tensile strength so that it can apply an important pressure onto the fabric in contact with the hot cy ⁇ linder.
  • the moisture contained in the fabric evapo ⁇ rates to produce steam.
  • An extremely good continuous decatizing shall be obtained with a watei—proof, inelastic carrier web or back cloth which is only slightly taut and consequently not subjected to wear, even though a very high mechanical pressure is exerted onto the fabric by means of pressing cylin- ders having their axes parallel to the axis of the central decatizing cylinder and the Lateral surface rotating at the same speed of the latter, of the car ⁇ rier web and of the fabric, being able to press the carrier web against the heated cyLinder while squeezing at the same time the fabric therebetween.
  • the heat to produce the decatizing steam is pre- ferabLy applied onto the fabric from the outside of apparatus, namely through the same pressing cylinders instead of the inner hot cylinder the temperature of which can be kept at about 100°C to avoid condensa ⁇ tion.
  • fIGURE_1 shows a schematic view of an illustra ⁇ tive apparatus according to the present invention
  • £ ⁇ UEI_2 shows a similar view of an alternati ⁇ ve embodiment of figure 1;
  • FIGURE_3 shows a partial view of the apparatus of Figure 1 l , taken in the direction of arrow H without considering rolls 3, 3a.
  • an endless, ring-shaped water-tight carrier web 2 is continuosly wound, partly but preferably along at least 180°, on a heated metal cylinder 1.
  • a set of rolls 3, 3a-3e causes said carrier web 2, of water-proof material to be fed at the same peripheral speed of cyLinder 1, while keeping the same at the correct position and without practically exerting thereon a pulling act on, except for the minimum necessary to prevent slipping about the feeding rolls themselves, thus ensuring a ring-like running.
  • a number or anyway at Least one pair -of pressing cylinders 6 rotatably mounted on respective axes parallel to the axis X-X of cylinder 1.
  • Their axes are pushed against the surface of cylin ⁇ der 1, placed centrally with respect to them, through known means such as the represented pneumatic or oleo- dinamic pistons 7, but also whichever different means, so as to exert a very high pressure onto the underly ⁇ ing sandwich.
  • c linder-piston 7 has been represented as directed radially with respect to axis X-X of cylinder 1, it is not to be excluded that the pressure is exerted by each cylinder 6 aLong a direction which is possibly different from the perpendicular to the surface of hot cylinder 1, at each generating line of contact between the two cylinders at each moment.
  • the pressure exerted by cylinder 6 has the dual purpose of producing a sensible squeezing of the fabric to be conditioned or decatized and at the same time to seal at the end points A, B of the endless sandwich the steam which would tend to escape owing to its pressure higher than the atmospheric one, which has been generated upon contacting of wet fabric with hot cylinder 1.
  • the water-proof web does not need to be elastic, but the apparatus with possibly hot, pressu- re cylinders may however show advantages also in this case, :n fact, while the elastic carrier web (e.g. rubberized or si l ⁇ cone-based) is capable of retaining the steam by itself, the pressing cylinders 6 of the present invention have however the useful effect of an increased squeezing action on the fabric, which is commonly insufficient if provided by only the elastic feature of the web, as stated before, unless extremely high tensions are exerted, but however in some que- stionable way.
  • the elastic carrier web e.g. rubberized or si l ⁇ cone-based

Abstract

Appareil de décatissage en continu d'un tissu (4) sur un cylindre (1) à une température au moins suffisante pour éviter la condensation, dans lequel le tissu humide ou mouillé est pris en sandwich entre ledit cylindre et une bande porteuse (2) étanche à l'eau et éventuellement rigide, et on applique une pression mécanique élevée obtenue à l'aide de deux cylindres rotatifs (6) dont les axes de rotation sont parallèles à l'axe du cylindre central, et qui serrent fortement contre ce dernier ladite bande porteuse tout en serrant simultanément la bande intermédiaire de tissu. On assure l'étanchéité à la vapeur à l'aide de deux joints en caoutchouc prévus de préférence des deux côtés du cylindre chauffé. Les cylindres de serrage, à l'exception du premier entrant en contact avec la bande, sont chauffés jusqu'à une température élevée de vaporisation (de 160 à 180 °C) lorsque le cylindre central n'est chauffé que jusqu'à 100 °C environ.
