Abstract:
Fibrous structures comprising a tuft. More particularly, the present invention relates to fibrous structures comprising at least two chemically different compositions wherein less than all of the chemically different compositions present in the fibrous structures forms a tuft, and processes for making such fibrous structures are provided.
Abstract:
The device comprises an essentially rigid smooth first cylinder (1) and an essentially rigid second cylinder 83), the latter having points (3P), the first and second cylinders rotate in opposite directions about respective axes of rotation (1A, 3A) and are pressed against each other, thus defining between themselves a lamination nip (5), through which said at least two layers are passed. There is also a pressure roller 87), with a surface (7A) that is less rigid than the first and second cylinders (1, 3), this roller interacting with the second cylinder and being pressed against it. The pressure roller forms with the second cylinder (3) an embossing nip (9) through which the layers (V1, V2) previously laminated in the lamination nip (5) are passed and in which they are embossed.
Abstract:
A patterned element for use in an embossing and adhesive application process. The patterened element comprises a material having an pattern disposed thereon, wherein the material comprises a polymer and has a Shore A hardness of greater than about 70, and has a critical surface energy of less than about 30 dynes/cm.
Abstract:
An embossing system is provided for embossing a web having a first embossing roll having embossing elements and a second embossing roll having embossing elements, wherein at least a portion of the embossing elements of the first and second embossing rolls are substantially oriented in the cross-machine direction. The embossing roll may be crowned, may have alignment means, and may be provided with precision gearing.
Abstract:
The invention relates to a method for manufacturing a sheet of paper tissue which is embossed by an embossing cylinder of which the surface is fitted at least in part with embossing elements. The elements include a frustoconical base portion and a tip portion. The method is characterized in that the tip segment includes a flat of which the area is less than 75% of the smaller cross-sectional area of the base. Preferably the area of the flat is less than 20% of the base cross-sectional area. The invention furthermore concerns a sheet thusly manufactured and to sheets made of several plies of which at least one is a ply of the invention.
Abstract:
An embossing roll includes a roll body and a plurality of plates which are removably secured to the roll body. Each plate includes an outer surface which is provided with an embossing pattern. The plates can be secured to the roll body by vacuum and/or mechanical devices.
Abstract:
The invention relates to a manufacturing method for an absorbent structure (10) having at least two plies (P1, P2) each constituted of at least one embossed sheet of creped absorbent paper, wherein the plies (P1, P2) engage between two engraved metal cylinders (CG1, CG2) fitted with protrusions (R1, R2), driven in synchronized rotation, and mutually nesting with a play (J) between the tops of the protrusions (R1, R2) of one metal cylinder (CG1, CG2) and the opposite trough surface (F2, F1) of the engraving of the other cylinder (CG2, CG1), the method being characterized in that the play (J) is less than the depth of the cylinder engravings and larger than the sum of the thicknesses (E1, E2) of the plies (P1, P2) which were previously shaped in such a matching manner that the plies (P1, P2) are not compressed when being engaged between the nested engraved cylinders (CG1, CG2).
Abstract:
The present invention is directed to an apparatus which is suited for use by women, children and the like who have limited physical strength to continuously stamp embossed patterns with clear outlines with the same spacing. A press roller is provided with an embossed pattern stamping die on a circular external circumferential surface, with its rotating shaft supported by bearings at a specific position, and is caused to perform axial rotation by a rotating drive force applied from the outside. A receptacle portion faces opposite the external circumferential surface of the press roller, with its opposing surface constituted as a flat surface or a convex surface to form a gap between itself and the press roller where a sheet-like object to be stamped is to be inserted.
Abstract:
Apparatus for fabricating discrete segments of cushioned web material for use as dunnage. The apparatus includes a mobile supply cart having at least one substantially horizontal support arm for receiving the hollow core of rolled web material. The apparatus also includes a separate driven rugation device with feed rollers for directing multiple plies of the web material in overlying, contacting relationship along a single path of travel. The separate cart and rugation device may be removably interconnected for lateral alignment. Driven interdigitized texturing rolls downstream of the feed rollers emboss a raised pattern on the web material, and a plurality of separating rollers downstream from the texturing rolls separate the plies of web material and direct them in divergent paths of travel. Combining rolls recombine the plies of textured web material such that the embossed areas of each ply do not directly overlie each other but are offset, creating void areas between the adjacent plies. A driven cutter downstream of the combining rolls severs the recombined offset embossed plies into discrete segments. The cutter may have a rotating disc blade with a peripheral edge which moves transverse to the longitudinal length of the plies to cut the plies. Last, driven exit rollers convey the cut segments of material from the rugation device.
Abstract:
A process for making two-ply nested paper towels utilizing matched steel engraved rolls, each steel roll having male and female elements spaced apart by a neutral zone, wherein nesting and ply attachment are achieved by partially conforming each of two plied to the steel rolls, applying adhesive to the raised portions of at least one of the partially conformed plies, and partially engaging the two steel rolls such that the raised portions of one ply contact the depressions of the other ply.
