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:
A method for producing partially embossed blanks (20) having an embossed and a non-embossed area is disclosed, said method comprising the steps, providing a continuous web (4) of an embossable material, guiding said web (4) between two embossing cylinders (2, 3), embossing the surface of the web (4) between the two embossing cylinders (2, 3), supplying the embossed web (4) to a stamping device (68) at which the blanks (20) are punched from the web (4), whereby one of the embossing cylinders (2, 3) comprises a marking (30), said marking (30) being readable by a first sensor (35), said first sensor (35) reading the position of the marking (30) and producing a signal, said signal triggers a printing device (40) producing a print mark (50) on the web (4) after the embossing process, identifying the position of the embossing, feeding the embossed and marked web (4), driven by feed rolls (14, 15), to a stamping device (68), said print mark (50) being read by a second sensor (55), said second sensor (55) producing a signal for controlling and adjusting a feeding distance D by which the feed rolls (14, 15) supply the embossed and marked web (4) to the stamping device (68) for punching the partially embossed blanks (20) from the web (4) at a predefined position in register with the partial embossing of the blank 20 A device for conducting said method is also disclosed.
Abstract:
Method for making a web paper material constituted by more paper superimposed plies, comprising a step of embossing at least one paper ply (1) in a corresponding embossing station (G) and its coupling by means of gluing with a further paper ply (2) advancing towards the said embossing station (G). The said further paper ply (2) is glued in a corresponding gluing station (C) upstream of said embossing station (G) with respect to the advancing direction of said further paper ply (2). The glue is applied to said further paper ply (2) when it results and advances between a roller (RA) of the gluing station (C) which provides to distribute the glue onto a side of the further paper ply (2) and a further roller (60) which guides and supports the further paper ply (2), the said further roller (60) being spaced from the said embossing station (G).
Abstract:
Method and device for producing a printed and embossed multi-ply web (3) of tissue paper or nonwoven having a good visual appearance. A first web-shaped material (1) is embossed in a nip (6) between a first embossing roll (4) and a counter roll (5), thereby creating a set of embossments. A first ink with a first colour is applied to a first subset of said set of embossments of said first web-shaped material while the material still resides on said first embossing roll. Thereafter an adhesive is applied to a second subset of said set of embossments of said first web-shaped material (1) while the material still resides on said first embossing roll (4). After that, said first web-shaped material is combined with a second web-shaped material (2) to form a multi-ply web (3). There is also provided a printed and embossed multi-ply web (3).
Abstract:
Method for producing a multi-ply web (26) of flexible material, such as paper and nonwoven material, by means of gluing the plies. Glue is transferred in subsequent steps to a first web shaped flexible material (1) by means of at least two patterned glue transfer rolls (5; 12), in a pattern corresponding to the pattern of the glue transfer rolls. A second web shaped material 816) is brought in contact with the glue bearing side of said first web shaped material (1) in at least one press nip (18; 23) between at least one patterned lamination roll (19; 22) and an impression roll (9). The at least one lamination roll has a three-dimensional pattern having a shape and configuration so as to apply pressure to the combined first and second web shaped materials substantially only just opposite at least some of the glue bearing areas of the first web shaped material (1), and is driven in registry with the first (5) and/or second (12) glue transfer roll. It is further referred to a multi-ply product produced according to the method.
Abstract:
Method for producing a multi-ply web (14) of flexible material, such as paper and nonwoven material and a multi-ply product produced according to the method. A first pattern roll (5), having a three dimensional pattern of alternating raised (6) and recessed portions (7) transfers glue to a first (1) web shaped flexible material in a first press nip (8) in glue sites (17) covering an area corresponding to between 0.03 and 9 % of the total area of the first web material and sparsely distributed over substantially the entire area of the first (1) web material. A second (10) web shaped flexible material is brought in contact with the glue applied side of said first (1) web material in a second press nip (12) between a second pattern (13) having a three-dimensional pattern corresponding to that of the first pattern roll, and an impression roll (9). The first and second pattern rolls (5, 13) are driven in registry.
