Definitions

  • Figures 4 and 5 show a schematic representation of the relative position of teeth 11 and 12 along the whole length of rollers 6 and 7 at embossing passage 13.
  • teeth 11 and 12 are obviously much greater in number, are much smaller, and are arranged contiguously (as shown in Figure 6); the distance between the centres of two contiguous teeth 11 or 12 may be selected from the group consisting of: 0.25, 0.3, or 0.4 millimetres, and is typically about 0.4 millimetres; and the length of a toothed outer surface of an embossing roller ranges between 140 and 150 millimetres, and is typically 148 millimetres, though a length of 300 millimetres or over is also possible.
  • supporting unit 18 is particularly advantageous in combination with the skew axis 9 and 10 arrangement of rollers 6 and 7.
  • the ability of at least one of rollers 6 and 7 (or, in further embodiments, of both rollers 6 and 7) to oscillate provides for more effectively meshing teeth 11 and 12, especially at the ends of rollers 6 and 7.
  • strip 5 travelling along path P downstream from embossing unit 3, winds substantially 180° about roller 27 by virtue of a guide roller 30 downstream from roller 27.
  • a motor 31 (shown schematically in Figure 1) rotates roller 27 at a tangential speed greater than that at which rollers 6 and 7 are rotated, so that, between embossing unit 3 and traction unit 4, strip 5 is subjected to traction which deforms it permanently in controlled manner to reduce undesired, embossing-induced deformation.
