A kitchen paper roll includes a kitchen paper that is formed by joining two sheets in a nested manner and is wound to form the kitchen paper roll. Each of the sheets includes an embossed region. The density of embossed protrusions on each of the sheets is greater than or equal to 0.075/mm.sup.2 and less than or equal to 0.2/mm.sup.2, the winding density of the kitchen paper is greater than or equal to 0.12 m/cm.sup.2 and less than or equal to 0.27 m/cm.sup.2, and the ratio of a minimum embossment area to a maximum embossment area in the kitchen paper is greater than or equal to 0.51.

An embossing and lamination assembly including two pairs of steel/rubber rolls, between which respectively a first paper ply and a second paper ply are returned, wherein an upper steel embossing roll is coupled with an upper embossing rubber counter-roll and a lower steel embossing roll is coupled with a lower rubber embossing counter-roll, and also including a glue delivery assembly, in contact on a side of the upper steel embossing roll, and a coupling roll, in contact with the opposite side of the upper steel embossing roll, wherein the surface of the upper steel embossing roll and/or of the lower steel embossing roll is heated with a heating device directly associated therewith. A relative embossing and lamination method is also disclosed.

Toilet paper includes at least two sheets on which embossments are formed and that are joined together in a nested manner. The area of a top part of an embossed protrusion of each of the embossments is between 0.8 mm.sup.2 and 1.5 mm.sup.2, and the area percentage of top parts of embossed protrusions of the embossments is between 5% and 10%.

Products having improved ply bonding, moldability and drape and methods for making those products are described. The methods comprise producing a multiply adhesively bonded product comprising a pattern of uniformly spaced microembossed elements with a bond area of less than about 0.020 inches/sq. inch.

An embosser/laminator machine has an adhesive unit releasably connectable with a main frame structure of the machine, and a roll extractor configured to move a roll between the main frame structure and an exchange position between the main frame structure and the adhesive unit when the adhesive unit is spaced from the main frame structure during removal and installation of the roll. The sub-frame comprising the adhesive unit may be formed with a bearing cap that cooperates with the main frame structure such that when the adhesive unit is connected with the main frame structure, the roll is operatively secured to the machine between main frame structure and the sub-frame of the adhesive unit for normal operation of the machine. When the sub-frame comprising the adhesive unit is released and spaced from main frame structure, the roll may be removed from and installed into the main frame structure.

The cellulose product comprises at least a first ply of embossed cellulose material and a second ply of embossed cellulose material, glued together. The first ply comprises: a first series of embossing protuberances with a first height (H1) and a top surface to which a glue is applied which bonds the first ply and the second ply to one another; a second series of micro-embossing protuberances with a second height (H2) lower than the first height (H1); a third series of micro-embossing protuberances with a third height (H3) lower than the second height (H2). The protuberances of the first series are distributed over areas of the first ply, where the micro-embossing protuberances of the second series and the micro-embossing protuberances of the third series are absent.

A method for producing a paper roll by conveying a first smooth ply between an upper embossing roll with first projections defining a decorative motif, and a glue distribution or clich roll; maintaining the clich roll side by side to the upper embossing roll, the first ply interposed between the upper embossing roll and the clich roll and subjected to incisions and to glue deposits at the first projections on one side of the first ply facing towards the upper embossing roll and on the opposite side of the first ply facing towards the clich roll; conveying a second ply between the upper embossing roll and a coupling or marriage roll; maintaining the marriage roll side by side to the upper embossing roll by exerting a coupling pressure to perform the final coupling between the first ply and the second ply at the glue deposits forming a multilayer paper.

Rolls of an embosser laminator unit may be calibrated with an iterative process of moving axial ends of the roll a set incremental distance until contact between the rolls is made and then making a correction to the distance based upon the end of the roll making contact. The rolls may be move an initial position where the faces of the rolls are devoid of contact with each other. One or both of the rolls may be rotated. The distance between the ends of the rolls may be decreased until the faces of the rolls make contact with each other. The distance between the first ends of the rolls may be increased by an incremental amount, and a determination of contact between the faces of the rolls may be made by alternate movement of the rolls by the incremental amount and position prior to contact.
