Embodiment Construction

[0051] figure 1 and 4 The first embodiment of the present invention is schematically shown. specifically, figure 1 An embossing-laminating unit is shown comprising a central embossing cylinder 1 around which three pressure rollers denoted by numerals 3, 4 and 5 are arranged. These pressure rollers may be covered with a deformable material such as rubber. The hardness of the covering rubber can be different for the three rollers. The central embossing cylinder 1 has protrusions or protrusions 1P ( Figure 1A ). Typically, these protrusions have a shape that reproduces the pattern imprinted on the embossing material.

[0052] A first gluing unit 7 is arranged between pressure rollers 3 and 4 , while a second gluing unit 9 is arranged between pressure rollers 4 and 5 . These gluing units can be of any form and are known per se. They are used to apply adhesive to the protrusions of the sheet conveyed around the central embossing cylinder 1 or to some of these protrusions...

Abstract

The embossing and laminating device comprises: a central embossing cylinder (1), provided with a plurality of protuberances (1P); at least three pressure rollers (3, 4, 5) disposed along the periphery of the embossing cylinder (1) and provided with a yielding surface, cooperating with the embossing cylinder; at least three paths to feed one or more plies (V1, V2, V3, V4) between the central embossing cylinder and each pressure roller; at least a first gluing unit (7) disposed between two consecutive pressure rollers and cooperating with said central embossing cylinder.

Description

technical field [0001] The present invention relates to a method and a device for producing embossed sheets or panels. In particular, but not exclusively, the present invention relates to the processing of paper products such as and especially tissue paper, such as toilet paper, dish towels, etc., having multiple embossed layers joined together by gluing. Background technique [0002] The embossing process is often used in the production of tissue paper products to obtain technical features and decoration of the final product. Embossing is accomplished by means of a variety of devices comprising at least one embossing cylinder having a plurality of protrusions or protrusions distributed over its surface in cooperation with a pressure roller, usually made of, for example, rubber Made of deformable surface. [0003] A sheet having one or more layers is conveyed and deformed under pressure between an embossing roller and a pressure roller, by which pressure roller and embossi...
