- FIG. 6 shows a variant of the embossing device (4) or of the embossing tool (5), in which two or more counter-rollers (8, 8 ') are assigned to an embossing roller (7).
- Counter rollers (8,8 ') are in the direction of the
- the counter rollers (8,8 ') may have a different perforation (12,12').
- the size and distribution of the openings of the perforation (12) of a counter-roller (8) may e.g. in the manner described above and shown in Figure 5 of the perforation (10) of the
- Embossing body (7) correspond.
- the openings of the perforation (12 ') of the downstream in the web running direction counter roll (8 ') are smaller than the openings of the perforation (10) of the embossing roll (7). They may correspond to the embodiment of FIG.
- the small openings of the perforation (12) are at the contact point (32) in each case in overlap,
- Openings and / or a nozzle (17) each emit a sharp fluid jet, which penetrates and perforates the respectively assigned and already existing deformation of the material web (2).
- FIG. 6 also shows the stationary arrangement of a diaphragm (35) instead of a nozzle (17) on the counter-roller (8).
- the counter rollers (8,8 ') are in Figure 6 to a
- Circulating means (16) are connected and together with a preferably supplied under pressure and in
- Circulation moving fluid in particular air, supplied.
- the supplied fluids can, as shown in Figure 6, similarly conditioned, in particular tempered.
- the web (2) can also be moved discontinuously. Modifications of the shown and described
- Embossing device (4) a single embossing tool (5).
- the embossing body (7), in particular the embossing roller is partially covered by the web (2) or
- embossing body (7) and possibly the counter-body (8) need not be part of the web guide (23). You can also change the contact area differently
- Transport direction (25) of the web (2) are distanced.
- the conveyor (22) is for this purpose
- the distance to the heating device (3) can just be chosen so large that no heat loss detrimental to the embossing process occurs in the material web (2).
- a thermal insulation can avoid or minimize heat losses of the web (2) and larger distances
- Embodiments may also be arranged further machine parts or components, which subject the web (2) of an additional treatment.
- a single web (2) passes through the heating device (3) and the embossing device (4).
- embossing device (4) In a modification to this is a
- the web (2) has a continuous, mat-like structure in the embodiments, wherein the
- Width is greater than the thickness. It may have a substantially flat and homogeneous surface on a broad side before entering the embossing device (3).
- Web (2) may alternatively be paralleled by individual ones Strands are formed.
- the claimed embossing technique and possibly the heat treatment technique is suitable in appropriate adaptation for webs (2) made of a different material, such as a tape or films of metal, plastic or the like. consist.
