A relative embossing and lamination method is also disclosed.

A warp determination device for a corrugated cardboard sheet manufacturing device is provided with: displacement value measurement method for measuring displacement values of a plurality of corrugated cardboard sheet pieces on the downstream side of a slitter scorer and on the upstream side of a sheet stacking unit; and warp status determination means for dividing a measurement range of the displacement value measurement method according to a width dimension of the plurality of corrugated cardboard sheet pieces, allocating the divided measurement ranges to each of the plurality of corrugated cardboard sheet pieces, and determining a warped status of the corrugated cardboard sheet pieces for each of the plurality of corrugated cardboard sheet pieces on the basis of measurement values from the displacement value measurement method in the allocated measurement ranges.

Products having improved handfeel and methods for making those products are described. The disclosed napkin product includes an emboss pattern that creates a pillow effect resulting in improved handfeel.

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.

A device for micro-embossing paper includes at least one micro-embossing unit to micro-emboss a wet paper ply. The micro-embossing unit includes a micro-embossing cylinder and a counter cylinder facing the micro-embossing cylinder at an embossing area where the wet paper ply is subjected to micro-embossing, and a heater to dry the wet paper ply. The micro-embossing cylinder includes a side surface partially wrapped by the wet paper ply. The heater heats at least one portion of the side surface partially wrapped by the wet paper ply to dry the wet paper ply.

A method for manufacturing a composite sheet includes a first step of, in a state that a curved part of a first sheet whose one surface rises and whose another surface is recessed and that a second sheet is overlaid on the first sheet, revolving a first roller to convey the first sheet and the second sheet; a second step of passing the sheets between the first roller and a second roller revolving so that a pressing part protruding outward in the radial direction from the outer peripheral surface of the second roller is inserted into the recess of the first roller; forming, in a region within the second sheet opposing the curved part, a protruding part which is surrounded by a flat part; and a third step of joining a boundary part of the first sheet to the second sheet.

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.

The device assists the customer in cleaning residue from their skin and body hair after they use a toilet for elimination, after they receive a cut or abrasion, or from other source. With the device, the person physically transforms toilet paper and other tissue-like paper in real time to have greater texture, density, and wetness, all three of which together facilitate cleaning better than dry paper or than wet paper without such increased density and texture. Being pocket sized and intended for repeated use, the device can be easily carried by or on the person and used in any bathroom or location anywhere without modification to the plumbing facilities, without risk of running out of a supply of pre-moistened wipes, and without damaging the environment or sewage and septic systems.

A method of manufacturing a paper sheet with improved softness and the paper sheet are provided. A method of manufacturing a paper sheet 101 according to the present invention includes a supply step of supplying a continuous base sheet 1, 1A, or 1B, and a plurality of times of pressing steps of applying, to a surface of the base sheet 1, 1A, or 1B, pressing force having a normal-direction component of the surface.

A coreless roll of an absorbent sheet product, such as napkins, toilet paper, towels etc., including a spirally wound continuous web of absorbent material having a first end and a second end and a coating composition comprising a specific polymer coated onto the second end is disclosed. The coreless roll has excellent resistance to collapsing, as well as excellent flexibility and elasticity. Moreover, the coreless roll has excellent disintegrability in water and can be used along its whole length. Also disclosed is a process for the manufacture of the coreless roll.
