Definitions

  • the invention relates to a method according to the preamble of claim 1 and a calender according to the preamble of claim 3.
  • treatment is intended to encompass everything that can be achieved with local plasticization or fusion associated with the action of a hot gravure elevation on a nonwoven made of thermoplastic fibers, i.e. in particular thermal bonding of the nonwoven through local bonding of the fibers (DE-OS 1 808,286, U.S. Patent
  • a steel engraving roller and a smooth steel counter roller rotate at the same circumferential speed and form a pair of rollers through which a fleece is made thermoplastic fibers is passed through.
  • the elevations of the engraving lie with their end faces against the counter-roller and, as heated, melt the portions of the nonwoven clamped in between on and on and bind the nonwoven by welding the fibers or displacing the melted mass to the edge of the end face of the engraving surface.
  • the melted thermoplastic material solidifies and forms connection zones that surround the perforations formed by the displacement and at the same time stabilize the fleece.
  • the web of the nonwoven is quite stiff and boardy in all of these procedures due to the many areas melted together to form a compact material.
  • the invention is based on the object of further developing the generic prior art in such a way that a "treated" nonwoven made of thermoplastic fibers is given a softer handle which is desired in many cases.
  • the web of the fleece can be positively cooled after leaving the roll gap and before breaking, whereby the thermoplastic material of the fleece becomes more brittle and the breaking action is more accessible.
  • Such a “positive” cooling is said to be by means of a Cooling device can be understood, in contrast to the mere cooling by emitting heat to the environment.
  • Claim 3 reproduces the invention in its apparatus aspect.
  • a first embodiment of a crushing device is given in claim 4.
  • the embodiment according to claim 5 is particularly advantageous with regard to the uniformity of treatment of the nonwoven in the roll gap that can be achieved over the web width.
  • the web is cooled on the loop path of the unheated or even cooled counter roll.
  • Passing the calender is thermally consolidated (claim 8), so that the fibers of the nonwoven are no longer loose before they enter the roll gap, but are combined into a geometrically defined structure. This prevents unwanted adherence of individual fibers on the hot engraving roller and sticking them with thermoplastic material.
  • FIG. 1 shows a side view of a calender for carrying out a treatment in the sense of the invention
  • Fig. 2 shows an enlarged side view of the nip of the calender of Fig. 1;
  • FIG. 3 shows a view corresponding to FIG. 1 of a calender embodying the invention and expanded by a crushing roller;
  • Fig. 4 shows a corresponding view of a calender with another breaking device.
  • 1 and 2 illustrate a specific example of a calender in which the treatment applied to the web 20 of the nonwoven 20 is a perforation.
  • the calender shown in Fig. 1 comprises a gravure roll 1 made of steel and a counter roll 2, which on a cylindrical roll body 3, a hard plastic covering
  • rollers 1, 2 form between them a roll gap 5, into which a pre-consolidated web 20 of a nonwoven V consisting of thermoplastic fibers is introduced. Since it is very important to introduce a line pressure that is uniform over the web width into the nip 5, at least one of the two rollers 1, 2 is designed as a deflection-controllable roller.
  • the ends of the rollers 1, 2 are mounted in a machine frame and are pressed against one another in the direction of the arrow.
  • the plastic covering 4 of the counter-roller 2 has a smooth cylindrical surface 7.
  • the engraving roller 1 has a uniform and pattern-like distribution over its entire surface. te Gavurerhebept 8, the outer end faces 9 are located in a cylindrical surface 10.
  • the engraved elevations 8 have a diamond-shaped cross section, seen in a tangential plane of the cylinder surface 10, and the largest dimension of the cross section is a few millimeters, for example 2 mm.
  • the clear distances between the individual engravings 8 are of the same order of magnitude.
  • the fleece V is pre-consolidated so that the fibers are held together and do not come into contact prematurely and individually with the surface of the engraving roller 1 heated to 220 ° C.
  • the engraving elevation 8 ′′ has already reached the narrowest point of the roll gap 5 and, with its end face 9 ′′, is practically in contact with the outer circumference 7 of the plastic layer 4.
  • the melted material of the zone 12 has been displaced by the pressure of the engraving elevation 8 ′′ between its end face 9 ′′ and the outer circumference 7 of the plastic covering 4 and forms a compacted ring 13 in the material of the fleece V surrounding the engraving elevation 8 ′′ .
  • the respective compacted ring 13 is a rigid surface element which, after cooling, gives the fleece V a boardiness or a hard feel under the softening area of the thermoplastic material, which is undesirable in many cases.
  • the roller pair of FIG. 1 is by a crushing roller 15 with a plastic covering 16 of z. B. supplemented less than 60 Shore D, which abuts the counter-roller 2 on the side opposite the engraving roller 1 and breaks the fleece perforated in the roll gap 5 in order to break the rings 13 of displaced molten material which are surrounded by the perforation perforations 14 and which are rigid To reduce zones within the fleece and in this way to reduce the boardiness of the fleece existing after leaving the roll gap 5.
  • the breaking takes place in the roll gap 25, after which the web of the fleece 20 has cooled sufficiently on the way around the unheated counter roll 2.
  • the rollers 1 and 15 are, as indicated by the arrows, deflection controllable and clamp the counter roller 2 between them. In this way, the treatment effect is particularly uniform across the width of the web.
  • FIG. 4 shows an embodiment in which a cooling section 17 is connected downstream of the roller pair 1, 2 and the breaking device is designed separately.
  • fleece V is blown with cooling air from a nozzle device 18 in order to substantially reduce the plasticity of the fleece from the rings 13 formed therein around the perforations 14.
  • the web of the fleece V then passes through a set of four parallel, circumferential to the web, in the direction of the fleece V at a short distance successive rollers 19 of small diameter, which are arranged in one embodiment in the embodiment and via which the fleece V zigzags is guided so that a breaking effect occurs due to the back and forth bending.

Abstract

L'invention concerne une calandre pour traiter une bande (20) constituée d'un non-tissé (V) de fibres thermoplastiques, ladite calandre comprenant un cylindre d'impression chauffé (1) en acier et un contre-cylindre (2) tournant à la même vitesse périphérique. Les plastifications et les fusions superficielles locales du non-tissé (V), produites au niveau des bosses d'impression, confèrent au non-tissé un toucher carteux. Pour réduire ce phénomène, la bande (20) du non-tissé (V) est aplanie après avoir subi un refroidissement au moins partiel.
