Problems solved by technology

[0005] However, the micro-embossing method mentioned above and described in patent No. EP1731296B1 has significant technical drawbacks mainly related to achieving a "thin paper" with the required resistance and softness starting from one or more paper layers. "The complexity and slowness of the formation of the paper roll and thus the operations that need to be performed to achieve the obtainable end product from such a paper roll

Embodiment Construction

[0021] With reference to the above-mentioned figures, the apparatus for micro-embossing of paper generally indicated by the reference numeral 1 comprises at least one micro-embossing unit 3 configured to micro-emboss the wet paper plies 5,6 flower. This micro embossing unit 3 comprises:

[0022] - the micro-embossing cylinder 7 and the counter cylinder 17 facing the micro-embossing cylinder 7 at the embossing zone 9 where such wet paper plies 5, 6 are subjected to micro-embossing, and

[0023] - Heating means 11 configured to dry the wet paper layers 5 , 6 .

[0024] According to the invention, the micro-embossing cylinder 7 comprises a side surface 13 partially surrounded by said wet paper layers 5,6. Furthermore, the heating device 11 is configured to heat at least a portion 15 of said side surface 13 partially surrounded by said wet paper layer 5 , 6 in order to dry such wet paper layer 5 , 6 .

[0025] The micro-embossing unit 3 comprises at least one motorized return r...

Abstract

Device for the micro-embossing of paper (1) comprising at least one micro-embossing unit (3) configured to micro-emboss a wet paper ply (5, 6), where the micro-embossing unit comprises a micro- embossing cylinder (7) and a counter cylinder (17) facing said micro-embossing cylinder at an embossing area (9) where said wet paper ply is subjected to micro-embossing, and heating means (11) configured to dry said wet paper ply. The micro-embossing cylinder comprises a side surface (13) partially wrapped by said wet paper ply. The heating means are configured to heat at least one portion (15) of saidside surface partially wrapped by said wet paper ply to dry said wet paper ply. The micro-embossing unit comprises at least one motorised return roller (19, 20), configured to ensure that the contactof said at least one wet paper ply with said counter cylinder occurs exclusively at said embossing area.

Description

technical field [0001] The invention relates to a device for micro-embossing of paper, in particular of "thin" type paper, and a paper processing line comprising said device. Background technique [0002] Currently, it is known, for example from patent No. EP1731296B1, that paper rolls of the "tissue" type are made via the method of micro-embossed paper layers, which have been previously wetted or have previously applied Lotion with moisturizing effect. The term micro-embossing means that a paper ply is embossed by means of a micro-embossing cylinder and an associated counter-cylinder having substantially uniformly distributed reliefs on the side surfaces, wherein the height of the reliefs is usually less than half a millimeter. Micro-embossing thus differs from traditional embossing in general, which involves embossing by means of embossing profiles with a higher height and often with a pattern that also has an aesthetic effect. [0003] It has been found that "thin" type...
