Definitions
- the invention relates to a nonwoven calender according to the preamble of claim 1.
- Such a fleece calender is known from EP-A-0733729 known.
- nonwoven webs are used high production output.
- high production speeds exists especially with light fleeces the problem that the nonwoven web due to the high Speeds are changed in their structure, so that the uniformity of the fleece is impaired.
- For systems with production speeds of 150 m / min and more is the entry of the nonwoven web into the nip problematic because of the structure of the nonwoven web solely due to the resulting air currents and the air to be displaced from the nonwoven web or can be destroyed. This usually happens through Increase the speed of subsequent Establishment and thus by default.
- the invention is therefore based on the object Fleece calender to create that at significantly increased Maintaining a production speeds ensures high fleece uniformity.
- the conveyor belt is permeable to air and in the area of the calender rolls Deflection rollers is deflected at least twice in such a way that the nonwoven web in the conveyor belt section between two Deflection rolls are brought tangentially to one of the calender rolls is.
- the invention makes it possible in an advantageous manner Way, the nonwoven web in front of the nip to a of the two calender rolls so that the nonwoven web permanently supported in the nip. Due to the constant management of the nonwoven web, this is due at no time in the area between the conveyor belt and Nip free. The carried with the nonwoven web and in the air it contains does not suddenly appear in the nip squeezed out, but can over a longer stretch be pushed out continuously.
- the fleece speed corresponds to the running-in speed into the calender, creating a warp-free transition reached by the conveyor belt in the fleece calender can be.
- the tangent to the one calender roll Conveyor belt section is preferably vacuumed, so that on the one hand the nonwoven web before transfer to the calender roll is firmly held on the conveyor belt and at the same time excess air is removed from the nonwoven web.
- the conveyor belt section between the deflecting rollers completely in line with the contour of the calender roll or partially curved.
- the Nonwoven web to the calender roll under a given Transfer contact pressure.
- the calender roll to which the nonwoven web is brought tangentially a larger one Has a diameter than the calender roll opposite it.
- the use of a large calender roll is helpful, the deflection angle for the nonwoven web is too small hold.
- a development of the invention provides that the Roll gap closer, second deflection roller of the conveyor belt section has a smaller diameter than that first deflecting roller of the conveyor belt section.
- the bigger one Diameter of the first deflecting roller leads to the fact that the nonwoven web is deflected more gently while the second Deflecting roller may have a smaller diameter can, because it no longer deflects the nonwoven web and because the nonwoven web has a smaller diameter this deflecting roller brought closer to the nip can be.
- the angle of inclination of the tangential to a calender roll brought up conveyor belt section is relative to the horizontal approx. 30 - 50 °. This measure also serves to reduce the deflection angle for the nonwoven web.
- first and / or second Deflection roller of the conveyor belt section from a screen roller consists.
- screen rollers as deflection rollers prevents wedges of air between the deflecting roller and the conveyor belt that can form the nonwoven web structure could interfere on the conveyor belt.
- the first deflection roller of the conveyor belt section can as a screen roller at least in the deflection area of the conveyor belt are under vacuum so that the deflection of the Nonwoven web on the conveyor belt permanently under negative pressure can be done.
- the second deflection roller of the conveyor belt section can also consist of a screen roller, at least can sometimes also be under pressure. To this This can detach the nonwoven web from the conveyor belt and the transfer to the calender roll are supported.
- the Nonwoven web on the upper or middle calender roll be brought tangentially. If the nonwoven web to the the middle of the calender roll is the direction of rotation opposite the calender rolls and the nonwoven web is running in the lower nip between the middle and the lower calender roll.
- a rotating perforated roller lie on it, which is transverse to extends the conveyor belt and the to compress the Nonwoven web serves.
- the peripheral speed of the perforated roller corresponds to this preferably the fleece speed on the conveyor belt.
- the perforated roller can also be vacuumed to remove the To facilitate air from the nonwoven web.
- the perforated roller extends from one to the length of the perforated roller extending suction hood surrounding the predominant Encloses part of the peripheral surface of the perforated roller, and only leaves the contact area of the nonwoven web free. A perforated roller so sucked enables a particularly effective Compact the nonwoven web without air turbulence produce.
- Fig. 1 shows schematically the inlet on a nonwoven calender with two calender rolls 4.6.
- the calender rolls 4,6 are vertically superimposed and form between a nip 8.
- a nonwoven web 12 is fed via a circulating air-permeable conveyor belt 10 from the carding system to the clanding rollers 4, 6.
- the upper calender roll 4 has a greater diameter 6. than the lower executable as an embossing roller calender the nonwoven web is at a high line speed of 150 m / min and brought more, and even non-woven fabrics having a basis weight of 12 g / m 2 a Can have a thickness of up to approx. 6 mm.
- nip 8 Since the nip 8 has only a fraction of the thickness of the nonwoven web in relation to the thickness of the nonwoven web, a large volume of air must be removed from the nonwoven web, particularly at the high transport speed, in order to avoid destruction of the nonwoven web structure when it enters the nonwoven calender.
- the fleece web guide is designed so that the Conveyor belt 10 brought up to one of the calender rolls 4 is, the conveyor belt 10 using two Deflection rollers 14, 16 is deflected twice.
- the between the two deflection rollers 14, 16 extending conveyor belt section 18 leads the nonwoven web 12 tangentially to the upper calender roll 4, whereby by vacuuming the Conveyor belt section 18 with the help of a suction box 24 the excess air prior to contact with the Calender roll 4 can be removed.
- the second deflection roller 16 is the Most of the unwanted air comes out of the nonwoven web 12 removed so that they easily in the nip 8th can break in.
- a slight nip between the deflecting roller 16 and the calender roll 4 can be adjusted.
- another suction box 22 is in one Conveyor belt section 20 upstream of the first deflection roller 14, whereby on the one hand the liability of the nonwoven web 12 on the conveyor belt 10 in advance of the first deflection is increased and on the other hand already a part of the excess Air in the nonwoven web 12 is removed.
- the first deflection roller 14 can also be designed as a screen roller be and additionally at least in the area of the deflection of the Conveyor belt 10 are under negative pressure. To this Way, the entire lead-in area, starting before the first deflection until the transfer of the nonwoven web 12 to the Calender roll 4 for sucking off the excess air and to increase the adhesion of the nonwoven web 12 on the conveyor belt be used.
- the second deflection roller 16 can also act as a screen roller be designed, the area behind the suction box 24 could be under pressure to detach the Support nonwoven web 12 from the conveyor belt 10.
- the first deflecting roller 14 can be compared to the second Deflection roller 16 have a considerably larger diameter, to be larger at the high belt speed To provide deflection radius.
- the conveyor belt section 18 can also under a defined Contact pressure pressed against the calender roll 4 to be removing the excess in this way To support air.
- Fig. 2 shows another embodiment of a nonwoven calender with three calender rolls 4,5,6.
- the calender rolls 4,5,6 are arranged vertically one above the other, the middle calender roll 6 has a smaller diameter than the other calender rolls 4.5.
- Fig. 2 shows two alternative ways for that Bring the conveyor belt 10 to the calender rolls 4,5,6.
- the nonwoven web 12 becomes tangential to the calender roll 6 brought up, the conveyor belt 10 under an angle of inclination to the horizontal of approx. 10 to 20 ° can run.
- the direction of rotation of the calender rolls 4,5,6 is opposite to the previously explained alternative, in which the nonwoven web 12 is fed to the nip 8. In this way, the nonwoven web 12 is in the nip 9 out between the calender rolls 4 and 6.
- FIGS. 1 and 2 can be in Area of the conveyor belt section 20 or as in Fig. 2, a perforated roller in front of this transport section 25 may be arranged on the conveyor belt overlying nonwoven web 12 is compacted by the portion that is also transported To reduce air in the nonwoven web 12.
- the perforated roller 25 is preferably provided with a suction hood 26 surrounded, which sucks the perforated roller 25 circumferentially. there is only the contact area with the nonwoven web 12 from the hood 26 is not detected.
- the sealing of the hood 26 against the perforated roller 25 in the transverse direction to the conveyor belt 10 can be done with the help of sealing lips.
