Abstract:
The device for satinizing and embossing flat materials comprises an embossing roll and at least one mating roll, said rolls being connected to a driving system and adapted to be driven individually or in common and to be resiliently pressed against one another while the individual teeth are flattened, and the embossing teeth being designed such as to produce in the corresponding locations of said flat material during its passage embossed marks whose appearance varies according to the viewing angle of the observer and/or the kind and/or the position of the lighting source, the embossing teeth which produce said variable marks having a different geometrical shape and/or surface than the satinizing teeth intended for satinizing. To this end, the surfaces of said embossing teeth and/or portions of the tooth space bottom are provided with microstructures. These microstructures allow producing largely forgery-proof marks which may furthermore provide a very decorative effect.
Abstract:
An embossing system is provided for embossing at least a portion of a web comprising a first roll and at least a second roll. The first roll and second roll may define a first nip for embossing the web. At least one of the first roll and the second roll has elongated embossing elements extending substantially in the machine direction and optionally at least one of the first and second rolls has elongated embossing elements extending substantially in the cross-machine direction. At least one of the first roll and the second roll may also have perforate embossing elements extending substantially in the cross-machine direction that may or may not be elongated. The embossing elements are capable of imparting one or both of a cube embossing pattern or a perforate emboss on the web. The web may be a cellulosic fibrous web, a portion of which is lignin-rich, high coarseness fiber having generally tubular fiber configuration. In addition, the web may be creped with an undulatory creping blade.
Abstract:
An embossing device having a first embossing unit for satin finishing a strip of packing material, and a second embossing unit for impressing graphics on the strip of packing material; the second embossing unit has two embossing rollers, at least one of which only has embossing pins in areas for impressing the graphics.
Abstract:
The present invention relates to an apparatus for producing a deep-nested embossed paper product comprising two embossing cylinders, each cylinder having a plurality of protrusions on its surface. The protrusions on each cylinder are disposed in a non-random pattern where the respective non-random patterns are coordinated to each other. The two embossing cylinders are aligned such that the respective coordinated non-random pattern of protrusions nest together such that the protrusions engage each other to a depth of greater than about 1.016 mm. The protrusions each comprise a top plane and sidewalls, with the top plane and sidewalls meeting at a protrusion corner. The protrusion corners of the protrusions of the embossing cylinders of the apparatus of the present invention have a radius of curvature ranging from about 0.076 mm to about 1.778 mm.
Abstract:
The present invention relates to processes for producing a deep-nested embossed paper products. The invention relates to a process for producing a deep-nested embossed paper products comprising one or more plies of paper where the resulting embossed ply or plies of paper comprise a plurality of embossments having an average embossment height of at least about 650 μm and have a high finished product wet burst strength relative to the unembossed wet strength. The present invention relates to a process for producing deep-nested embossed paper products comprising the steps of a) delivering one or more plies of paper to a deep-nested embossing process, b) conditioning the one or more plies of paper, wherein the conditioning step comprises heating the one or more plies of paper, adding moisture to the one or more plies of paper, or both heating and adding moisture to the one or more plies of paper, and c) embossing the one or more plies of the paper where the resulting embossed ply or plies of paper comprise a plurality of embossments having an average embossment height of at least about 650 μm.
Abstract:
An embossing system for embossing at least a portion of a web is provided comprising a first embossing roll having male embossing elements, a second embossing roll having male embossing elements, wherein the first and second embossing rolls define a first nip for receiving the web, and a third embossing roll having male embossing elements, wherein the second and third embossing rolls define a second nip for receiving the web, and wherein at least a substantial portion of the embossing elements of at least one of the first, second, and third embossing rolls are substantially oriented in the cross-machine direction.
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 sheet of tissue paper includes at least one first embossed zone (A1, A2) having protrusions on a surface corresponding to alveoles on the other. The alveoles have a substantially polygonal base and the sheet includes at least one second, unembossed zone (B). In the invention, the alveoles 101′, 102′ are configured along at least one array, the mutually facing sides of two adjacent alveoles define a bridge (P) having rectilinear or substantially rectilinear edges of length L which is larger than its greatest width D, one or several bridges connected to each other subtending a path preferably between two second unembossed zones (B) which are separated by at least one first, embossed zone (A1, A2). The invention also relates to a cylinder embossing such a sheet.
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 85° to 95° from the machine direction.
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.
