Abstract:
A method of embossing an absorbent web with a machine direction undulatory structure is described. The web has a plurality of ridges extending in its machine direction occurring at a frequency, F, across the web and the method includes providing the web to an embossing station where the web is embossed between a first and second embossing roll, each of which rolls may be provided with a plurality of embossing elements configured to define a plurality of embossing nips. At least a portion of the embossing nips are substantially oriented in a cross-machine direction with respect to the web and have a cross direction length, L. The product F×L is from about 0.1 to about 5.
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:
An embossing system for embossing and perforating at least a portion of a web is provided comprising a first embossing roll having embossing elements and at least a second embossing roll having embossing elements, wherein the elements of the first and second embossing rolls define perforate nips for embossing and perforating the web and wherein at least a predominate number of the perforate nips are substantially oriented in the cross-machine direction. Moreover, substantially all of the nips defined by the embossing elements of the first and second embossing rolls can be substantially oriented in the cross-machine direction. Further, the cross-machine embossing elements are at an angle of about 85null to 95null from the machine direction.
Abstract:
An embossing and laminating machine is described which comprises a first embossing cylinder (3) with a surface provided with a first set of protuberances (P3) disposed with a first pitch in a first direction (Lx3) of alignment and with a second pitch in a second direction (Ly3) of alignment, the said first and the said second direction of alignment forming between them an angle (&agr;) other then zero; a second embossing cylinder (5), with its axis (A5) parallel to the axis (A3) of the first embossing cylinder (3), and with a surface provided with a second set of protuberances (P5) disposed with the said first pitch in a third direction (Lx5) of alignment and with the said second pitch in a fourth direction (Ly5) of alignment; and a first and a second pressure roller (7, 9) interacting with the said first and the said second embossing cylinder (3, 5) respectively. The first and the third direction of alignment (Lx3) are inclined with respect to the axes (A3, A5) of the corresponding embossing cylinders (3, 5) such that, in the lamination nip, there is only partial corresponding between the protuberances of one cylinder and the protuberances of the other cylinder.
Abstract:
A method of embossing a sheet of non-woven fibrous web, e.g. toilet tissue, with a series of identical boss elements arranged in a uniform pattern in a manner to avoid nesting of the embossments and resulting non-uniform product rolls when the sheet is rolled onto a mandrel. The embossments are uniformly spaced in rows which in the longitudinal direction form an angle in the range of 15.degree. to 23.degree. relative to the edge of the sheet or roll and an angle in the range of 40.degree. to 57.degree. relative to the cross direction of the sheet or roll.
Abstract:
Absorbent paper sheets in multi-ply web form in which the outer webs of the sheet are creped and consist of a series of ribs and grooves. The webs have their ribs secured together by adhesive dispersed in a pattern consisting of individual adhesive zones. The adhesive zones are obtained by providing in embossing apparatus cooperable rolls each having alternating ribs and grooves, the ribs of one roll being provided with protuberances and the other with recesses. The protuberances cover a relatively small area of the total rib area and carry a web on the protuberances through an adhesive applicator so that a relatively small area of the web receives adhesive for attachment to a second web.
Abstract:
MULTI-PLY CREPED CELLULOSE WADDING MATERIAL USEFUL IN SHEET FORM AS A PAPER TISSUE TOWELING AND THE LIKE. THE MULTI-PLLY WADDING MATERIAL STRUCTURE INCLUDES LANDS AND RECESS AREAS EMBBOSSED INTO OUTER WEBS OF THE SHEET. IN TWO-PLY TOWELLING MATERIAL INTERNAL LANDS OF ONE PLY EXTEND TRANSVERSELY INTO INTERNAL LANDS OF THE OTHER AND THE TWO PLIES ARE SECURED TOGETHER AT SPACED CROSS-OVER ZONES OF THE LANDS. THE LANDS BRIDGE RECESS AREAS AND LIMIT SHEET
EXTENSION IN THE WET AND DRY STATE OF THE SHEET. ADDITIONAL WADDING PLIES MAY BE PROVIDED BETWEEN THE OUTER EMBOSSED PLIES. THE OUTER WEBS ARE EMBOSSED PRIOR TO LAMINATION IN A STEEL NIP, FOR EXAMPLE, AND ARE UNITED INTO A SHEET STRUCTURE IN THE STEEL TO STEEL NIP.
Abstract:
The disclosed tissue products have an embossing pattern that is aesthetically pleasing and provides improved product properties, such as good bulk, while reducing processing issues, such as wrinkling. The embossing patterns generally comprise a background and a foreground pattern where the background pattern is the dominate pattern and provides the product with a uniform appearance that connotes femininity, softness and cleansing. The background pattern is preferably formed entirely from open design elements such as first, second and third open, curvilinear line elements, wherein the second and third line elements are discrete, similarly shaped curvilinear line elements that are arranged parallel to one another and spaced apart about 1.0 mm or less.
Abstract:
A device is provided to produce an embossed multi-ply material, comprising: a first embossing-laminating unit (3) comprising a first embossing cylinder (5) equipped with first projections (5P) defining a first pattern, a first pressure roller (7) cooperating with said first embossing cylinder (5), a first laminating roller (9) and a first glue dispenser (11), disposed between said first pressure roller (7) and said first laminating roller (9); an embossing unit comprising at least a second embossing cylinder (25) provided with second projections (25P) defining a second pattern and a second pressure roller (27) cooperating with said second embossing cylinder (25); a first path (P1) through said first embossing-laminating unit (3); a second path (P2) for at least a second ply (V2) towards and through said second embossing unit (23); a third path (P3) for said third ply (V3).
Abstract:
An embossing apparatus for applying an embossing pattern to a wrapper for a smoking article, the embossing apparatus configured so as to act to at least partially minimize the reduction, in at least one direction, in the tensile strength of the wrapper resulting from the application of said embossing pattern.
