Definitions

• Roller arrangement for finishing windable, in particular pre-consolidated web goods and a corresponding web goods
• the present invention relates to a roller arrangement for finishing a windable, in particular pre-consolidated web product, comprising a first and a second embossing roller, which form a roller gap for embossing the web product between them; wherein the first roller has a plurality of projections for producing structural elements in the web material and the second roller has a plurality of depressions for receiving the projections, with a roller gap section formed between the needle and the depression for producing a border of locally hardened Web goods is formed, wherein the nip section has at least a first conical consolidation section.
• the invention also relates to a corresponding sheet material.
• a device for producing a liquid-absorbing nonwoven fabric with three-dimensional structures and openings is already known from publication US 2018/0228666 Ai.
• the device described therein has a plurality of conical needles which are engaged with complementary conical indentations. In the resulting conical gap, the material to be embossed is compressed and the tip of the needle creates openings in the nonwoven.
• the device disclosed has the disadvantage that the material to be embossed is only insufficiently clamped during the production of the openings, so that the material can slip in the course of the production of the openings in the gap and the structures in the embossed material are therefore only slightly uniform can be. Furthermore, the structures produced in the nonwoven only have a uniform compression intensity, see above that when configuring the nonwoven in terms of absorbency and stability, only a compromise solution can ever be considered.
• the nip section has at least one consolidation section configured essentially parallel to the roller axes.
• the invention has the advantage that a better alignment of the rolls to one another in the production process is made possible by means of the hardening section configured parallel to the roll axes.
• the section designed parallel to the roll axes fixes the rolls to one another and thus ensures a self-centering effect.
• the rollers can be operated at higher speeds than the devices known from the prior art.
• the hardening section designed parallel to the roll axes ensures improved material clamping, so that the material cannot slip over the conical areas and the openings can therefore be produced with greater accuracy.
• the conical consolidation section on the one hand and the consolidation section formed parallel to the roll axes on the other hand can produce areas of different compression in the material, so that on the one hand a high material stability and on the other hand a pleasant feel and good absorption properties can be realized.
• the web material can be a non-woven fabric, for example.
• the nonwoven can be hydrophilic or hydrophobic.
• the web material can also be tissue or film.
• the web material can be single-ply, multi-ply and/or laminated.
• the stepped profile can have a plurality of conical and a plurality of strengthening sections formed essentially parallel to the roll axes.
• the consolidation section which is aligned essentially parallel to the roll axes, to surround the conical consolidation section at least in sections.
• the consolidation section which is aligned essentially parallel to the roll axes, can be located on the level of the pitch circle diameter of the first and the second embossing roll.
• the consolidation section, which is aligned essentially parallel to the roll axes can extend over the entire roll width and can be provided wherever none of the rolls has a projection or a depression.
• the projections are designed as needles.
• the needles can be designed to create openings. If the projections are formed as needles, the structural elements are consequently formed as openings. The clamping of the material by the conical and essentially parallel to the roll axis consolidation section enables the needles to produce the openings in the web material in a targeted and accurate manner.
• the projections can be in the form of embossed elevations, which are provided for producing structural elements in the form of elevations. If the projections are in the form of embossed elevations, the structural elements are consequently in the form of elevations. In this case, too, the elevations can be introduced very precisely into the material due to the good material clamping.
• the first conical strengthening section is formed between a conical proximal flank section of the projections and a conical mouth section of the recess.
• the projection can be arranged on a base area.
• the projection can extend radially away from the roll surface, starting from the base area.
• the base area can have a greater width than the maximum width of the projection.

• the indentation may have a substantially cylindrical portion which extends radially into the roll surface. In an opening area to the roller surface, the indentation can have a chamfer on its upper side, which forms the conical opening section of the indentation.
• the projection can have a round cross-section exhibit. Alternatively, the projection may have an oval cross-section. The projection can thus be essentially conical.
• the hardening section configured essentially parallel to the roll axes is configured between a saddle region of the projections configured essentially parallel to the roll axes and a shoulder region of the depression configured essentially parallel to the roll axes.
• the saddle area can be formed by an upper side of the embossing base.

A smaller nip thickness in the nip section configured essentially parallel to the roll axes ensures good clamping of the material and higher compression. As a result, greater material stability is generated in the hardening section formed parallel to the roll axes.
