Abstract:
Provided is a pair of plates for a rotary processing machine having the following configuration and a method of mounting the same by which the pair of plates can be mounted on the respective outer circumferential surfaces of a pair of cylinders with high precision. When a female recessed plate and a male raised plate are overlapped with each other so as to make processing portions of the female plate correspond to those of the male plate, fitting protrusions are fitted into respective fitting portions. Accordingly, the movement of the fitting protrusions is restricted both in the width direction of the plates and in the mount direction of the plates. Concurrently, guiding protrusions are respectively inserted between corresponding pairs of guide protrusions in the guiding portions. Accordingly, the guiding protrusions are guided so that relative movement of the guiding protrusions is allowed only in the mount direction.
Abstract:
An apparatus for producing a deep-nested embossed product including a first embossing member and a second embossing member. The first embossing member has a plurality of discrete embossing elements disposed in a first non-random pattern. The second embossing member has a plurality of second embossing elements including at least one linear embossing element. The second embossing elements are disposed in a second non-random pattern such the first non-random pattern and the second non-random pattern nest together to a depth of greater than about 0.01 mm.
Abstract:
The device for satinizing and embossing packaging foils comprises at least two embossing rollers that are each provided with a toothing consisting of individual teeth, the pyramidal teeth having an essentially rectangular horizontal projection, and the sides of the teeth being essentially parallel and perpendicular, respectively, to the longitudinal axis of the embossing roller. In contrast to the prior art, the opening angle (α) between the radially aligned adjacent tooth flanks is smaller than the opening angle (β) between the axially aligned adjacent tooth flanks, and the tooth height in the radial direction, measured from the tooth tip to the tooth bottom, is greater than the tooth height in the axial direction measured from the tooth tip to the tooth bottom. This dimensioning and arrangement of the teeth provides an improved gearing with a reduced specific pressure as well as an improved processing of the paper part of the foil that results in its better folding, curling, and tubing behavior.
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:
A process for determining the placement of an adhesive relative to an emboss pattern is disclosed. The disclosed process is suitable for forming an embossed multi-ply substrate. The process comprises the steps of: 1. Providing the emboss pattern as a pattern of elements; 2. Providing a grid comprising a plurality of vertices, the grid corresponds to an adhesive application pattern; 3. Providing each vertex of the plurality of vertices with an initial position; and, 4. Overlaying said emboss pattern upon said grid.
Abstract:
A thermoplastic bag for storing food items may include a first sidewall and an opposing second sidewall joined to the first sidewall to define an interior volume. The first and second sidewalls may be made from pliable, sheet-like thermoplastic web material. The sidewalls may be formed with a pattern of ribs. When a tensioning force is applied to the sidewall, the ribs may open so that the sidewall may become generally more planar. Opening the ribs may cause the sidewalls to stretch or expand thereby adding to the overall area of the bag. The thermoplastic material may have a shape memory characteristic that may cause the ribs to reform after the tensioning force is alleviated.
Abstract:
A flexible die is used in an embossing apparatus in which a pair of flexible bases (2a, 2b) are respectively wrapped around a pair of cylindrical rollers disposed opposing each other, and a sheet to be processed (S) is passed through between the pair of rollers, thereby performing embossing. The pair of flexible bases (2a, 2b) are constituted by a female flexible base (2a) and a male flexible base (2b) that are mated with each other, a line-shaped convex portion (3a) corresponding to the contour of an embossing processing pattern is formed in the female flexible base (2a), and the convex portion (3b) is formed in the male flexible base (2b), the convex portion (3b) being fitted within the area encompassed within the line-shaped convex portion (3a) of the female flexible base while leaving an interval from the inner circumferential surface of the line-shaped convex portion (3a). A concave portion (30) is formed in the convex portion (3b).
Abstract:
A process for making an embossed web. A precursor web is provided between a forming structure and a static pressure plenum. The forming structure has a plurality of discrete apertures or depressions. Pressure is provided by the static pressure plenum against the precursor web and the forming structure to force the precursor web into the apertures or depressions of forming structure to form the embossed web. The resulting embossed web has a plurality of discrete extended elements.
