Definitions

  • the present invention relates to an improved apparatus for continuously decatizing fabrics on a cylinder with 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 temperature of 160-180°C.
  • a very hot rotating steel cylinder e.g. at a temperature 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 cylinder.
  • the moisture contained in the fabric evaporates to produce steam.
  • An extremely good continuous decatizing shall be obtained with a water-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 cylinders 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 carrier 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 preferably 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 condensation.
  • 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 action, except for the minimum necessary to prevent slipping about the feeding rolls themselves, thus ensuring a ring-like running.
  • Their axes are pushed against the surface of cylinder 1, placed centrally with respect to them, through known means such as the represented pneumatic or oleodinamic pistons 7, but also whichever different means, so as to exert a very high pressure onto the underlying sandwich.
  • 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, pressure cylinders may however show advantages also in this case.
  • the elastic carrier web e.g. rubberized or silicone-based
  • 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 questionable way.
  • the steam has not to be retained at both ends A, B where sealing is ensured by the elastic tension of web 2, even only one pressing cylinder 6 could reach the purpose satisfactorily, as shown in figure 2.

  2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß
    die Preßzylinder (6) mit Ausnahme des ersten, der mit dem Webstoff (2) in Kontakt kommt, beheizt sind.
  3. Vorrichtung nach Anspruch 2, dadurch gekennzeichnet, daß
    die Preßzylinder (6) auf eine hohe Temperatur zur Dampfbehandlung des Gewebes (4) erhitzt werden.
  4. Vorrichtung nach einem der vorangehenden Ansprüche, dadurch gekennzeichnet, daß die Andrückmittel (7) pneumatische oder öldynamische Zylinder-Kolbensysteme sind, deren Druck auf die Achsen der Zylinder (6) in senkrechter Richtung zu der Oberfläche des Zylinders (1) gerichtet ist.
  5. Vorrichtung nach einem der vorgehenden Ansprüche, dadurch gekennzeichnet, daß der Webstoff (2) im wesentlichen keine Elastizität besitzt und die Anzahl der Preßzylinder (6) mindestens zwei beträgt, wobei der erste und der letzte Zylinder jeweils mit den Punkten (A, B) zusammenfallen.
  6. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß der Webstoff (2) elastischer Natur ist und als Dampfabdichtung wirkt, die breiter ist als das Gewebe (4), wobei zwischen den Punkten (A, B) lediglich ein Preßzylinder (6) vorgesehen ist.
  7. Vorrichtung nach einem der vorangehenden Ansprüche, dadurch gekennzeichnet, daß an beiden Seiten des Zylinders (1) in einem Bereich, der sich zwischen den Randkanten des Gewebes (4) und des breiteren Webstoffes (2) erstreckt, zwei gummierte Umfangsdichtungen (5, 5') zur Dampf abdichtung in Axialrichtung und in Zusammenwirkung mit dem wasserdichten Webstoff (2) auf dem Zylinder angebracht sind.
