Abstract:
The present invention provides a process which in a preferred embodiment includes the steps of (a) applying a hot melt adhesive to a heated roll rotating at an intitial tangential speed; (b) milling the adhesive to a reduced thickness and accelerating said adhesive through a series of metering gaps between a plurality of adjacent heated glue rolls; (c) applying the adhesive to a conformable glue appication roll rotating at a tangential line speed which is higher than the initial tangential speed; (d) applying the adhesive to a first patterned embossing roll which is engaged with a second patterned embossing roll having a complementary pattern to the first embossing roll, the embossing rolls being heated; (e) passing a web of sheet material between the first and second embossing rolls at the tangential line speed to simultaneously emboss the web and apply the adhesive to the web, such that the adhesive forms an adhesive pattern between embossments; (f) transferring the web from the second embossing roll to the first embossing roll; (g) stripping the web from the first embossing roll; and (h) cooling the web.

PROBLEM TO BE SOLVED: To provide an apparatus equipped with a roll (18) having the pinup structure of tooth parts (2) and a roll (19) having the pin-down structure of corresponding recessed parts (4) and constituted so as to perform the emboss processing and satin processing of an inner liner especially for tobacco, food and medicines. SOLUTION: Different from a conventional apparatus, a logogram corresponding part is provided only to one of rolls for the purpose of forming a logogram and the recessed parts of the other roll have a uniform shape with respect to the respective tooth parts of one roll. By this constitution, it becomes unnecessary to produce the rolls so as to allow the rolls to coincide with each other as a pair and it becomes unnecessary to replace the rolls as a pair with respect to abrasion or the alteration of the logogram to enable the production of the rolls at a low cost.

Abstract:
The present invention pertains to the following: a manufacturing method and a manufacturing device for a paper cup in which a pair of embossing rolls form opposing embossments in a middle section of the paper cup or an outer sleeve which is wrapped around the outer circumference of the middle section; and the improvement of the paper cup. [Solution] Each of dies formed on the surface of a pair of embossing rolls has substantially an identical shape and is provided with the following: a frame section that is formed of a flat surface and that partitions cells which are surrounded by lattice frames extending at regular intervals in the horizontal and vertical directions and mutually crossing; and a projection section that includes four lateral-wall surfaces that raise up from the four directions of the sides of a cell towards the center of the cell, and a peak section formed in a plane or linear shape by assembled distal ends of the lateral-wall surfaces. A pair of the dies are characterized in that: the projection sections of the dies are disposed in a direction of approaching a blank; the vertical and horizontal lengths of a quadrangular shape of a unit section are each set as one pitch, the unit section including a cell, frame sections of two sides respectively extending along the adjacent vertical and horizontal side of the cell, and an intersection of these two frame sections; and one die of the pair is offset by half the pitch in the horizontal and vertical directions with respect to the other die.
Abstract:
Absorbent members, especially bulked absorbent members, and methods of making the same are disclosed. The absorbent member may be in the form of a unitary absorbent fibrous layer comprising at least some cellulose fibers. The unitary absorbent fibrous layer is at least partially stratified through its thickness. The absorbent member may also have a plurality of discrete deformations, such as depressions and/or apertures in its surfaces. The method involves subjecting a precursor web to at least one cycle (or pass) through a mechanical deformation process. The mechanical deformation process utilizes a first forming member and a second forming member that form a nip therebetween through which the precursor web is passed. The first and second forming members are moving at different speeds relative to each other when they come together to form the nip.
Abstract:
An apparatus (1) and method for producing embossed paper or laminated metallic foil sheets (55) comprising means for feeding an elongate strip (20) of paper or laminated metallic foil, a pair of matched embossing rollers (5, 10) disposed to receive such a strip from the feeding means, and means for receiving such a strip from the embossing rollers after being embossed thereby, and for cutting such strip into sheets. The rollers have a plurality of embossing sectors (75) arranged on the surface thereof. At least one of the sectors imparts a first embossing, and at least another of the sectors imparts an alternate embossing different in appearance from the first embossing. The sectors are dimensioned similarly to the foil sheets. At least one group of the sheets carry the first embossing while at least another group of the sheets carry the alternate embossing.
Abstract:
The device for the satining and embossing of innerliners for tobacco, food and pharmaceutical products, comprises a roll (18) with a pin up configuration of the teeth (2) and a roll (19) with a pin down configuration of corresponding recesses (4). In difference to the prior art, at only one of the rolls the part corresponding to the logo has been worked on to form the logo, whereas the recesses, respectively the teeth, on the other roll have not been altered in their shape. This allows a lower cost production of the rolls since no matching pairs of rolls have to be produced and exchanged for wear or changing logo.
Abstract:
Feine Strukturen eines Motivs sind in einem vorbestimmten Motivabstand in eine Folienbahn (1) mittels eines rotierenden Prägezylinders (7) einzuprägen. Der Prägezylinder (7) rollt auf einem Gegendruckzylinder (8) ab und weist eine Ausnehmung (10) zur Befestigung der Prägematrize (12) auf. Bei jeder Umdrehung des Prägezylinders (7) entsteht während einer Freiphase ein Zwischenraum (14) zum Gegendruckzylinder (8), der für eine Relativbewegung zwischen der Folienbahn (1) und der Prägematrize (12) genutzt wird. Eine Steuereinrichtung (24) erzeugt die Relativbewegung mit einer einstellbaren Amplitude, die durch den Motivabstand auf der Folienbahn (1) vorbestimmt ist. Diese Relativbewegung ermöglicht ein Prägen im vorbestimmten Motivabstand auf der Folienbahn (1) unabhängig vom Durchmesser des Prägezylinders (7). Die nutzbare Länge der Prägematrize (12) beträgt mehr als 50% des Umfangs des Prägezylinders (7).
