  • Figure 9B shows the flat development of a surface section with knurled (wheel) knobs in high magnification, which is analogous to the layer embossing Process by creating one through all tissue layers of the tissue product deformation of the tissue web that becomes effective, embossing knobs in the tissue trains that mechanically connect the individual layers.
  • the distance 70 that is between parallel reference lines of the same edges of the End faces of successive knurled knobs to those of neighboring knurled knobs is particularly preferred embodiment shown equal.
  • the distance 69 A parallel edges of the diamond-shaped end faces of each one Knurled knob 69 is the same and has in a particularly preferred embodiment a value less than 2 mm.
