Abstract:
The object of the present invention is an absorbent paper product including at least three plies, and a method of manufacture therefore. The absorbent paper product is of an approximate specific surface weight between 36 and 105 g/m2, and includes at least three plies, namely a central ply and two embossed upper and lower outer plies each including salient patterns composed of at least in part discrete protrusions. The plies are joined by joining at least part of the protrusions of each of the outer plies to the central ply. At least one of the outer plies has a pattern density larger than 30 protrusions/cm2. The embossed lower outer ply (2) includes combined high and low patterns (5 and 7) of respective heights (H) and (h). The central ply (4) and the embossed upper outer ply (3) are joined in the nested mode to the embossed lower outer ply (2) at the level of at least part of the tops of the high pattern (5) of height (H) of the embossed lower outer ply (2).
Abstract:
A web of flexible material, such as paper and nonwoven material is embossed by printing the web in a selected pattern by bringing it into a first nip between an impression roll and a printing roll carrying a colorant in a selected pattern; subsequently embossing the web by bringing it into a second nip between a pattern roll and the impression roll, the pattern roll having a three dimensional pattern of alternating raised and recessed portions, the three dimensional pattern being interrupted by relatively smooth areas, so that the web will be embossed in selected areas while leaving other areas substantially unembossed; the pattern roll and printing roll being synchronized so that embossing occurs mainly in the areas of web that are not printed in the selected pattern. The printing and embossing steps may also be reversed so that the web is embossed before printing.
Abstract:
An embossed multiple ply paper product having a nested latticework embossment pattern providing a cloth-like, quilted appearance and a process for embossing and bonding such multiple ply paper product. The multiple ply paper product comprises a latticework of cells composed of n rows of embossment elements nested within an interfacing latticework of cells composed of n+1 rows of embossment elements.
Abstract:
A web with an embossed surface with a plurality of lows separated by a plurality of highs is provided with a shadow effect by passing the web between a pair of counterrotating rollers, a backup roller for supporting the web on its reverse surface and an ink application roller for applying ink to selected portions of the embossed surface of the web. The ink application roller is formed of a hard elastomeric material and its outer surface is engraved to have a plurality of highs corresponding to and engaging the lows of the embossed surface of the web and a plurality of lows corresponding to and overlying the highs on the embossed surface of the web.
Abstract:
A module for a web-processing machine includes a sub-frame to which are mounted an operating roll (such as a die roll), and means urging the operating roll in one direction. The sub-frame can assume a position in which the operating roll is juxtaposed against and parallel with a driven anvil roll, and a further position in which the sub-frame is released, allowing the operating roll to move away from the anvil roll, so that the operating roll can be quickly and easily removed for replacement or maintenance. Preferably, the sub-frame is hingedly connected to the machine for rotation between the above positions.
Abstract:
Disposable paper products, such as paper toweling, are provided with an indicator means which is disposed on said disposable paper product in a discontinuous or combination discontinuous/continuous pattern. The indicator means gives a visually recognizable signal to a user that desirable properties of the disposable paper product are maintained, even after the disposable paper product has become wetted with a substantially transparent aqueous liquid. The wet gray scale difference for the disposable paper product of the present invention is at least about 64 gray scale units when the disposable paper product is wetted with a substantially transparent aqueous liquid.
Abstract:
An absorbent multi-layer sheet, with at least two layers each constituted of at least one embossed ply of creped absorbent paper having a specific surface weight between 10 and 40 g/m.sup.2 per ply, with an external surface forming the outer side of the multi-layer sheet and an inner surface, the inner surface of the first layer including first and second protrusions and the inner surface of the second layer including third protrusions nested between the-protrusions of the first layer, the two layers being bonded together by at least part of the protrusion tips of one layer adhesively joined to the other layer between two protrusions, is characterized in that the bonding is implemented by the first protrusions of the first layer, the second protrusions having a lesser height than the first ones and their tips being adhesive-free.
Abstract:
Method of manufacturing a hygiene paper product in form of a continuous paper web (W)of sheets partly separated by perforation lines (9) and wound to a log of predetermined longitudinal length, providing a continuous paper web (W), moving the continuous paper web in a direction of its longitudinal extension, providing at least one embossed pattern on the continuous paper web, providing in the area of an embossing station at least one mark (6, 7) onto the continuous paper web, which mark (6, 7) is in register to the embossed pattern, sensing the mark and controlling perforating means for registering the perforation lines (9) with the embossed pattern thereby imparting perforation lines to the continuous paper web in predetermined longitudinal distances, winding up the resulting web to logs, and cutting the log into rolls.

Abstract:
Device for coupling two or more paper webs or plies by gluing, comprising gluing means destined to apply glue to a paper ply (N2) and pressure means which are located downstream of said gluing means and press more paper plies (N1, N2; N3) onto each other determining their coupling. The said gluing means comprise at least one body (1) provided with corresponding reliefs (R1) which apply the glue on predetermined gluing zones or areas of a paper ply (N2) advancing along a predetermined direction (F2) and said pressure means comprise a presser (3) which is located downstream of the said gluing means with respect to the said direction (F2) and is provided with corresponding reliefs (R3) which exert, on said paper plies (N1, N2; N3), a localized pressure on pressure zones or areas interfering with said gluing zones or areas, so that the glue passes through the glued ply (N2) only in correspondence of said pressure areas or zones.
