Embodiment Construction

[0033] The application of the invention to a complex embossing lamination unit having two embossing rolls and two pressure rolls, and one laminating roll will be described below. However, it must be understood that the invention may also be advantageously implemented in simpler or other types of embossing units. For example, advantages can also result from applying the invention to simple embossing machines with only one embossing roll and one pressure roll.

[0034] refer to figure 1 , in one possible embodiment, the embossing unit generally indicated by 1 includes a first embossing roller 3 and a second embossing roller 5, the first embossing roller 3 and the second embossing roller 5 are respectively connected with the first embossing roller The pressure roller 7 and the second pressure roller 9 cooperate. Each embossing roll 3, 5 has a plurality of protrusions 3P, 5P on its cylindrical surface, while each pressure roll 7, 9 comprises a cylindrical surface coated with a l...

Abstract

An embossing unit comprising: at least one embossing roller (3, 5), provided with embossing protrusions or recesses (3P; 5P) on a cylindrical surface; - at least one pressure roller (7; 9) coated with an elastically yielding material (7E; 9E) and cooperating with the embossing roller (3; 5); at least one actuator (15; 17) that presses the pressure roller and the embossing roller against each other; an automatic position adjustment system (37, 39), to adjust the reciprocal position of the pressure roller (7; 9) and the emboss not ing roller (3; 5).

Description

technical field [0001] The present invention relates to machines for converting continuous webs. In particular, the invention relates to the improvement of so-called embossing units for processing paper or other materials, in particular cellulosic materials. The invention also relates to embossing methods. Background technique [0002] In the field of processing sheets or webs of paper or similar materials, the term embossing refers to a process of permanent deformation of the web, which produces raised areas with a technical or aesthetic function or a dual technical and aesthetic function or Protrusion generation. [0003] For example, in the processing of so-called "tissue paper" for the production of kitchen paper, toilet paper, paper towels and napkins or other similar items, embossing is used to decorate the cellulose web and to give the material special technical properties, such as Significant thickness, greater softness and absorbency or other properties greater t...
