Problems solved by technology

In the first place the glue—being an expendable material—increases the cost of the finished product.
In the second place, the presence of glue decreases the softness of the product, which becomes more rigid, and h

Embodiment Construction

[0027]FIG. 1 shows a log, that is, a roll of considerable axial length, delivered from a rewinding machine, located downstream of an embossing unit which performs, on the tissue paper web material or the like, differentiated embossing with differentiated gluing to obtain the objects mentioned above. The log, indicated as a whole with L, will subsequently be cut orthogonally to the axis A-A thereof, to be divided into a plurality of rolls R of a smaller axial length, corresponding to the final dimension of the product destined for use. The ends of the log have been trimmed to eliminate the irregular portion which forms in this end area during winding.

[0028] As shown schematically in FIG. 1 and illustrated in greater detail hereunder by a series of examples of embodiment, the web material indicated as a whole with N of which the log L is composed is embossed differentially with areas with increased embossing at the level of cutting planes P indicated with a dashed line in FIG. 1, alo...

Abstract

The sheet product, such as paper, wound in a roll, comprises at least two plies (V1, V2) joined together by gluing, at least one of which is embossed. The product has longitudinal bands or areas (1, 3) which are characterized by a different quantity of glue, with more glue in proximity to the edges.

Description

TECHNICAL FIELD [0001] The present invention relates to sheet products, with two or more plies joined to one another by gluing, for example and in particular (although not exclusively) made of tissue paper. [0002] More specifically, the invention relates to sheet products especially of the type wound in a roll, such as kitchen towels, toilet paper and the like. STATE OF THE ART [0003] In the production of toilet paper, kitchen towels and other products made of tissue paper or creped paper, two or more plies of paper joined to one another by ply-bonding or gluing are normally used. When the plies are joined by gluing they are normally embossed, that is, subjected to permanent mechanical deformation with the formation of protuberances on the plies. The glue is applied to the front surface of the protuberances of at least one of the two plies and the plies thereby embossed and provided with glue are laminated between two embossing rollers or between one embossing roller and one laminat...
