Definitions
- the invention relates to a method for manufacturing of a relatively soft, essentially flat, but three-dimensional product and a corresponding one Product itself.
- Such products as a whole flat products are usually considered in terms of their Volume increased by an embossing process.
- This Volume increase can on the one hand Affect appearance and secondly the technical Characteristics. For example, if a tissue or a similar paper product is embossed, so can, in addition to an improved appearance, the Touch and button properties can be improved.
- These touch properties can transform the Starting product by embossing the Improve the absorption properties of the product.
- different materials come into question, e.g. B.
- EP 0 313 766 A2 and US disclose 5,229,186 a method and an apparatus for embossing Films. It is also known from US 5,296,289 flat starting product after an embossing process Subject to stretching. The state of the art provides no suitable measures ready which the Improve the touch properties of the product.
- This secondary has a special effect Volume increase as a superimposition of the embossing caused volume increase, since the embossing pattern of the Intermediate from a variety of each other networked joint parallelograms is formed and that stretch as optimal in about one direction runs diagonally through the parallelograms and thereby especially through diagonally opposite hinge points, which of course are not real hinge points in the mechanical sense represent, but rather from the embossing process result in lines of compacted material crossing each other and limit the parallelograms used in networking then act similarly to a pantograph if the stretching forces be applied.
- An increase in volume is understood to mean that Embossing bulges of the whole flat starting product, so that primarily a Volume increase in the direction perpendicular to the large one Surface of the starting product takes place.
- the expression “relatively soft” implies the need to be able to carry out an embossing process at all.
- expression also includes a deformability of the Product in that the stretching process permanent deformation can be achieved as well as by the Embossing process.
- the product should also be in the final state certain and possibly special flexibility and softness have, depending on the purpose and whether that Appearance or the touch characteristic is in the foreground.
- the problem is also solved by a relatively soft, in large flat but three-dimensional product Claim 2.
- the secondary volume increase convex and on the convex side of the primary Volume increase forming embossed pattern can be arranged. But it can also be concave.
- the embossing pattern does not have to be, but can be symmetrical.
- the secondary volume increase can be particularly achieve more favorably if the embossed in the embossed pattern
- Individual shapes in plan view have a shape that between the shape of a circle and a square or Rectangle is located. However, one should there is a clear deviation from the circular shape.
- the embossing pattern broadly forms a diamond pattern.
- the present invention provides Claim 8 an embossing tool for producing the Intermediate product according to claim 1 ready.
- embossing tool with its design has a significant impact on the stretch caused superimposed, permanent secondary Increase in volume.
- the use of a is particularly expedient So-called "female" embossing tool, which has recesses in which is the material of the flat starting product for the permanent primary volume change is pressed.
- the embossing tool has a connection between them the recesses interconnected webs on the corresponding bulges of lines pressed together by the webs and thus recessed material are limited, which lines in particularly favorable due to the "female" embossing Form parallelograms that are network-like are interconnected that this network at Applying opposite stretching forces in the direction the large area extension and essentially in Diagonal direction of the joint parallelograms of the Intermediate acts like a pantograph. Accordingly the parallelogram should be aligned in the machine direction if the stretching is in the machine direction.
- the secondary volume expansion is particularly easy achieve effectively when the side walls in the embossing tool of the recesses starting from the tool surface run at a certain acute angle on all sides.
- This angle should preferably be no less than about 40 ° and in particular not less than about 60 °. In this angle is particularly advantageously 65 °.
- the number of individual shapes per square centimeter influences the formation of the secondary in a positive way Increase in volume. So this number of individual forms 0.5 to 6 and in particular 1 to 2.5 per square centimeter be.
- the dimension of the recesses of the embossing tool has also influence the training of the permanent secondary volume increase through stretching. So it can Ratio of the depth of the recesses to the width 0.1 to 0.5 and in particular be 0.2 to 0.3.
- the recesses in the embossing tool have staggered Side walls in such a way that starting from the Tool surface several wall sections in the depth of the Recesses are strung together and the tips Angle that the wall sections form to the tool surface, be smaller from wall section to wall section.
- the webs between the recesses of the embossing tool can preferably have a width of 0.5 mm to 3 mm and in particular from 1.2 mm to 2.2 mm.
- a profile can also be provided in webs, and in particular can be a number of along the same in the webs trained recesses may be provided. Form thereby bulges in the embossed lines of the product additional volume increases.
- Figs. 1a and 1b are matching patterns shown, but so that the Fig. 1a based on the tool pattern as the embossed pattern would be viewed (reverse view) and Fig. 1b as the corresponding pattern of the embossing tool itself. Because the product is especially designed for that Intermediate product is produced by the embossing tool, is only based on the three embodiments Embossing tool described, because this also the product as such is marked.
- FIG. 1a to 1c a pattern is shown, which as "Diamond” pattern can be called. Opposite the Reality corresponds to the pattern according to FIGS. 1a and 1b Scale of 2: 1 and the individual representation according to FIG. 1c Scale 10: 1. This also applies to Figures 2 and 3.
- the embossing pattern of the embossing tool comprises webs 1, of which four each form a square or parallelogram, so are strung together that a network through the webs results. It can be lined up in the web 1 Recesses 2 may be provided, which are embossed Show intermediate bulges small bulges. This However, recesses do not necessarily have to be present his. There is a large recess between the webs 3, which is formed by staggered side walls 4a and 4b. The side walls 4a form one with the tool surface 5 Angle ⁇ and the side walls 4b an angle ⁇ , the smaller is as the angle ⁇ .
- Fig. 3 shows a "pillow" shaped pattern, the pattern offset to the machine direction by an angle ⁇ of 1.5 ° can be. With such an offset, the repeat height is approx. 183.21 mm, d. H. 18.5 figures per repeat.
- a tissue paper as a starting product with the respective embossing tools as shown in Fig. 1, 2 and 3, an embossing in the form of a pattern is awarded, a rubber roller presses the tissue paper against the webs 1 and in the recesses 3, whereby the Starting product experiences an imprint that in Area of the webs the material is compressed and stiffened and 3 bulges 6 are formed in the area of the recesses, as can be seen, for example, in FIG. 6.
- the Embossed edge areas are there with reference number 7 Mistake. These are specifically here as embossed lines designated. They form according to the network of webs Lines as shown in FIG.
- FIG. 4 shows a schematic representation of an illustrative example not belonging to the invention with individual side walls and an associated angle ⁇ .
- 5a shows a sequence of staggered one after the other Side walls 4a, 4b with corresponding angles ⁇ and ⁇ , where the angle ⁇ is smaller than the angle ⁇ , measured to Tool surface.
- 5c it is also possible to to provide first side wall sections 4a, which is dome-like a curved surface 4d connects.
- Example 1 A two-ply tissue paper web was drawn off from an initial roll and fed to an embossing mill.
- the two-ply tissue paper had a basis weight of 21.9 g / m 2 and a width of 50 cm.
- the tissue paper consisted of 100% cellulose pulp.
- the embossing plant consisted of a steel roller and a rubber roller.
- the steel roller had a diameter of 198 mm.
- the rubber roller had a diameter of 174 mm with a rubber thickness of 17 mm and a rubber hardness of 33 shore.
- the female embossed recesses had a dimension according to FIGS. 1b and 1c of the drawings in connection with the associated description.
- the embossing pressure between the rolls was 9420 N / m.
- the product embossed with this embossing machine was then one Drafting system fed (all in one device) and there stretched across the width with a stretching force of 30 N / m.
- the above-mentioned secondary volume increase occurred one that the first created by embossing Volume increase was superimposed.
- the starting product was an increase in volume of 21.4%.
- the strength increased in the machine direction 17.6% from the starting product i.e. the Flexibility in this direction increased).
- the elongation at break decreased by 12.3% compared to the starting product and that Strength in the cross-machine direction by 36.8%.
- the product was wound up as sections spaced in lengths by perforation on a roll of toilet paper.
- This roll had a diameter of 123.2 mm and a compactness of 635 cm x 10 -3 .
- the aforementioned strength corresponds to the machine direction the tensile stress in the machine direction until it breaks. It was the two-ply tissue paper or the finished product in Samples 76mm wide cut and then in Machine direction aligned. The samples were between two clamps of a tension tester clamped. The The clamps were at a distance of 51 mm and the Sample was pulled apart at 250 mm per minute. As The result was the peak force in N up to the break recorded. It was similar in the direction across Move machine direction. The volume increase was like this measured that leaves cut from the starting material ten times and sheets of the end product five times on top of each other placed in an electronic thickness gauge with a Foot pressure of 2.9 kPa were inserted. The results were recorded in thousandths of a mm.
- the basis weight was determined so that again ten Sheets cut from the raw material or five sheets of the two-ply end product as squares of 10 x 10 cm were placed on top of each other. The sample was then weighed and the result multiplied by 10 and then recorded as kPa.
- the diameter of the finished toilet paper roll was like this measured that a calibrated band to display the Diameter wrapped around the circumference of the finished roll has been.
- the compactness or winding hardness of the finished toilet paper roll in cm x 10 -3 was measured as follows. The finished toilet paper roll was held by a rigid rod that was pushed through the core. Then a tester loaded with a light load was placed on the circumference of the roll. After a set-up time of approx. 15 seconds, the measuring device was read zero. Then a heavier weight was put on and after stabilization after 15 seconds a second reading was taken. The difference in readings was recorded as the compactness of the roll and was measured in thousandths of a cm. Accordingly, the compactness was 635 cm x 10 -3 .
- Example 2 The procedure is basically the same as in example 1, but with the following changes.
- the embossing tool corresponded to the information shown in FIGS. 2b and 2c.
- the diameter of the steel roll was 191 mm.
- the decrease in strength in the machine direction (increase in flexibility) compared to the starting product was 22.9% in the finished roll and the corresponding decrease in strength in the transverse direction was 39.3%.
- the increase in volume increase was 12%.
- the finished roll had a diameter of 123.7 mm and a compactness of 622.3 cm x 10 -3 .
- Comparative example A comparative example was realized with a sample according to FIG. 1. However, the diameter of the steel roller was 197 mm. The angle ⁇ was 38 °, the value b was 7.2 mm and the value d was 1.3 mm. This only resulted in a volume increase of 1.7%. The diameter of the finished toilet paper roll was 120 mm and the compactness was only 503 cm x 10 -3 .
