Abstract
The invention relates to a relatively soft, largely planar, though three-dimensional product, obtainable by means of an embossing tool for converting a relatively soft, planar starting product as a result of embossing to the extent that an embossing pattern exists which comprises a plurality of “hinged parallelograms” that are limited by lines of compressed material such that when tractive forces are applied, this hinged parallelogram structure behaves like a pantograph and a secondary bulk is superimposed as a result of a stretching process on the primary bulk produced by the embossing.

A method of producing a relatively soft, essentially planar, though three-dimensional product including the production steps of:
- a) converting to an intermediate product, a relatively soft, essentially flat planar starting product by embossing a three-dimensional pattern that generates a primary bulk with respect to said starting product;
- and
- b) stretching this intermediate product achieved by embossing of said initial product essentially in the direction of its largely planar extension for generating a superimposed, secondary bulk with respect to said intermediate product converted by embossing.
A relatively soft, largely planar, though three-dimensional product having a three-dimensional embossing pattern and a secondary bulk superimposed by stretching on this embossing pattern as an inherent primary bulk.
A relatively soft, largely planar, though three-dimensional product, obtainable by a planar three-dimensional intermediate product provided with an embossing pattern that forms a primary bulk and produced by an embossing tool, said intermediate product being lent a lasting secondary bulk that is superimposed on said primary bulk as a result of stretching essentially in the direction of its largely planar extension.
