Definitions

  • the invention relates to a method for solidifying and / or for thermal bonding and / or for embossing according to the preamble of claim 1.
  • Devices of this type with calender rolls are known to be used for the treatment and processing of web-shaped materials such as non-woven fabrics in order to bring about consolidation, aesthetic embossing or thermal bonding of the non-woven fabric.
  • One or both rollers are heated, and furthermore, the one roller or both rollers can be provided with a surface pattern which is formed by raised, discrete points located on the circumference of the calender rollers.
  • the rotating calender rolls form a gap between them in which the nonwoven fabric is guided under pressure.
  • the degree of coverage between opposing pairs of raised, discrete points forms an embossing surface which determines the pattern of the finished nonwoven fabric, and a connection or consolidation takes place on the embossing surfaces.
  • the known method and the known device for the nonwoven fabric each result because it has a very specific embossing pattern, and the nonwoven fabric therefore has a very specific embossing surface, which is given in percent.
  • the end product is to be a soft material, a relatively small embossing area is sufficient, whereas a larger embossing area must be selected for stronger materials.
  • the invention intervenes, which is based on the object of creating a method - and a device suitable for carrying out the method - which enables a rapid and thus extremely economical change from a first to a desired different embossing pattern or to another percentage
  • the embossing area enables a continuous change in the percentage of the embossing area during the tep production process should be possible within wide limits.
  • the invention is based on driving the two calender rolls at an identical speed, so that a very specific predetermined degree of coverage or a very specific percentage embossing area is achieved.
  • it is now provided to briefly interrupt the synchronous running of the two calender rolls and practically bring about a short phase shift between the individual revolutions, in order to then immediately switch back to the identical synchronous speed of the two calender rolls.
  • the short phase shift also results in a different degree of coverage, since different areas of the raised discrete points now lie on top of one another than before. This also changes the percent embossing area. So it can be easier Depending on the requirements of the end product, the percentage embossing area can be changed, which is a particularly important advantage of the invention during operation.
  • a laborious exchange of the calender rolls to adapt to different embossing surfaces of the desired end product is no longer necessary. While the known devices and methods always pay close attention to the exact synchronism of the two calender rolls, the invention, on the other hand, treats the surprising way of briefly interrupting this synchronism and then restoring it. The associated displacement of the surfaces which overlap when the calender rolls roll off results in a new embossing pattern in the desired manner, without it being necessary to replace the calender rolls themselves. Rather, these can be used unchanged.
  • the calculated bombage can be distributed equally between the two calender rolls.
  • the invention is not limited to this.
  • the different embossings can be made Areas in addition to the method described so far can also be achieved in that the two calender rolls are arranged displaceably in the axial direction. In this case, the synchronous speed of the two calender rolls can be maintained; the degree of coverage changes due to the axial displacement of one calender roll relative to the other.
  • a drive unit with an adjustment gear is preferably provided for driving the calender rolls at synchronous speed, which enables an angular displacement of one calender roll relative to the other calender roll.
  • the drive consisting of motor and gearbox, expediently forms a unit.
  • the transmission has an input shaft for the motor, two output shafts for the two calender rolls, the differential adjustment gear being integrated into the main transmission and being operable manually or with a servomotor via an adjustment shaft.
  • the device shown schematically in Fig.1 comprises two calender rolls 10 and 12, which are driven at identical speed but in the opposite direction, so that a web-shaped material can be guided and embossed along a contact surface 14 (line pressure) between the calender rolls.
  • the calender rolls 10 and 12 can have a bombage; however, it is also possible to use cylindrical calender rolls.
  • the upper calender roll 10 and the lower calender roll 12 are driven by a motor 24 via a gear 28 and drive shafts 22, 36 so that they run synchronously.
  • the adjustment gear 32 is a differential gear known per se (harmonic drive or specon differential gear), which enables an adjustment in the barrel via the adjustment shaft 34 manually or with a servo motor.
  • the adjusting shaft 34 By means of the adjusting shaft 34 it is now possible to briefly change the "translation" of the adjusting gear 32, i.e. the speed at the input of the adjustment gear 32a deviates briefly from the speed at the output 32b. Then the original transmission characteristic of the adjustment gear 32 is set again, i.e. the two calender rolls 10 and 12 are again driven at the same speed.
  • the two calender rolls 10 and 12 each have an identical surface pattern 38, which is shown in detail in FIG. 2.
  • the surface pattern 38 is formed by a multiplicity of raised locations (squares) 40 which are arranged in a regular structure. With a0 the side of a square 40 is designated, and t0 indicates the division, which here is the same in both directions - horizontally and vertically.
  • the sides a0 of the squares 40 run parallel or perpendicular to the respective axis 18 or 20 of the associated calender rolls 10, 12.
  • the embossing area F to be specified in percent or the maximum value F max and the minimum value F min can be specified as follows:
  • the relationship for the ratio of F max to F min applies In the top row in Fig. 3 with the full area Coverage is based on a shift s0 between the two calender rolls 10 and 12, ie the shift is zero, since the individual squares 40 come to lie one on top of the other.
  • the dashed hatching 50 indicates that there is no overlap between the individual squares 40 of the upper and lower calender rolls 10 and 12, but that they comb alongside one another.
  • the shift s2 must therefore not be set because it can not achieve embossing.
  • the different embossing surfaces can thus be easily realized with the new device.
  • the side surfaces of the squares 40 run parallel or perpendicular to the axes 18, 20 of the calender rolls 10, 12.
  • it is also possible to form the surface pattern to arrange the ends of the squares at an angle of inclination ⁇ to the axes 18 and 20, as shown in FIGS. 5 and 6 for the case ⁇ 45 ° on the basis of the surface patterns 44 which are again identical on the two calender rolls 10, 12.
  • the raised places (squares) are designated by the reference number 46, and the individual degrees of coverage 48 are indicated by hatching.
  • the following relationships generally apply here: In the special case that the side length a0 is equal to half the division t0, we get for The minimum stamping area F min is then 0%.
  • the percentage stamping area is calculated according to the following general relationship:
  • the different degrees of coverage 48 occurring in the different displacements s0, s1, s2, s3 and s4 in FIGS. 4 and 5 can be clearly recognized by the hatches 48.
  • 5 is based on the fact that a0 is greater than t0 / 2, while FIG. 6 applies to a0 less than or equal to t0 / 2.
  • the percentage stamping surfaces can be mathematically determined (the individual formulas are not shown here).
  • the advantage of the new method and of the new device is not only limited to being able to set different embossing surfaces with simple measures during operation, but - as FIG. 5 illustrates - it is also possible to use the different embossing surfaces or degrees of coverage 48 with different patterns. There desired effects can also be achieved optically.
  • the invention is not limited to the thermal consolidation of a nonwoven fabric, rather the invention can also be used to achieve surface effects or surface structures on any sheet-like materials (for example paper, synthetic leather, aluminum, etc.).
  • the invention achieves the following advantages over the prior art, for example in the thermal consolidation of nonwovens: Downtimes when changing the embossing area are significantly reduced or eliminated; Specified strengths of the finished nonwoven can be safely maintained despite the raw material fluctuations and / or fluctuations in the fiber orientation during fiber deposition by gradually adjusting the embossing surface during thermal consolidation; Investment costs for embossing rollers when using multiple embossing patterns are drastically reduced: When using, for example, three different embossing patterns, eight rollers (including replacement rollers) are necessary with conventional technology; when using the invention, only four rollers, including replacement rollers, are required; Lower costs for embossing rollers because of Using two "patterned” rollers the etching depth of each roller only has to be half as deep; Nonwoven that has been thermally bonded using the invention has a significantly softer "grip", since the "secondary bonds" that result from one-sided, full-surface contact with a smooth roller according to the prior art are not present.
