A formed sheet metal material and methods, tools and apparatus for forming the sheet metal material in which a pattern of projections and depressions are cold worked in a first portion and, simultaneously, indicia is embossed in a second portion of the sheet material. The cold worked portion is formed with the projections and depressions configured and distributed such that lines drawn on a surface of the formed sheet material between adjacent rows of projections and depressions are not rectilinear. The indicia is indicative of the alignment between the tools.

A module for a folder-gluer (1) includes a frame (13) having two substantially vertical front and rear walls (14, 16) and at least one functional arrangement (28, 33) held by the frame (13), at least one transverse element (17, 18), mechanically connecting and maintaining parallelism between the first and rear walls (14, 16) and the transverse element is configured with at least one substantially horizontal portion forming an apron (19), which is configured to permit an operator (30) to climb onto the frame and to access the functional arrangement (28, 33).

The invention relates to a method including very superficial embossing combined with superficial laminating, which involves a slight reduction in thickness, the method being applied to plates several millimetres thick and to aluminium sheets having a thickness of less than 0.3 mm, supplied, in either case, as independent plates or in a continuous roll.

A method for the continuous in-register embossing of a stretchable film is provided where a repeating printed image or a laminate may be formed by way of the stretchable film in an embossing station. The embossing station may include a rotating embossing roll having an embossed image and an associated rotating counter-roll. The printed image length of the film may be stretched longitudinally before the embossing contact with the embossing roll to a length greater than or equal to or smaller than or equal to the embossed image length or the circumference of the embossing roll. The maintenance of register of the embossing may be achieved by way of a relative speed between the circumferential speed of the embossing roll and the web speed of the film in the embossing station.

The present invention relates to a film in which a protective layer (100), a base material sheet (200), a UV-curable resin layer (300) having a concave-convex surface, a metallic layer (400), a primer layer (500), and an adhesion layer (600) are laminated in sequential order. Also, the present invention relates to a method for manufacturing said film.

The present invention discloses a decorative material rolling mill having an adjustable roll gap, which includes: a left frame and a right frame connected to each other; and an upper roll and a lower roll, two ends thereof being axially disposed on the left frame and the right frame; and a driving mechanism for driving the upper roll and the lower roll to rotate; and further includes: a rolling gap adjustment mechanism for driving the upper roll or the lower roll to move vertically along the left frame and the right frame, thereby adjusting a rolling gap between the upper roll and the lower roll according to the thickness of a shearing die. The present invention uses a rolling gap adjustment mechanism to adjust a rolling gap between an upper roll and a lower roll, thereby accommodating thickness differences among die sheets, upper rolling plates, and lower rolling plates from different manufacturers. Various rolling gap adjustment mechanisms disclosed by the present invention are simple in structure and convenient to use.

A method and device of embossing individually light-reflecting areas on a foil material, the method and device comprising feeding a foil material into a roller nip between a pair of rollers, wherein the pair of rollers comprises a first roller and a second roller, providing each of the first roller and second roller at their respective surfaces at least in a determined perimeter, respectively with a plurality of polyhedron-shaped positive projections and a plurality of negative projections complementary to the positive projections, whereby the plurality of positive projections are arranged according to a 2-dimensional grid. The plurality of polyhedron-shaped positive projections seamlessly and gaplessly join with those corresponding negative projections at the intended embossing of the foil material, hence enabling a homogeneously jointed embossed polyhedron-like shape in the foil. The method and device further comprise, for the purpose of providing a plurality of light-reflecting areas on the foil material, that are intended to reflect light in line with a table of reflectivity values for the 2-dimensional grid, according to an orientation and shape of each of the plurality of light-reflecting areas, and enabling a perception by the human eye of a user, of the intended reflected light on a determined wide viewing angle covered by reflected light from any of the light-reflecting areas, a step of adjusting for each of the plurality of light-reflecting areas to be provided, an orientation and shape of the corresponding positive projection in the 2-dimensional grid, that is intended to emboss the light-reflecting area.

An in-line method for marking a substrate made of extruded synthetic material, the method including the steps of extruding the synthetic material through an extrusion die to form the substrate, marking the substrate by scrolling the substrate obtained from the extrusion die between two rotatably mounted and temperature-controlled rollers with an upper roller and a lower roller, one of the rollers having an impression forming the negative of a decoration or a texture to be marked on one face of the substrate, this same roller or the other of the rollers including at least one notch allowing to guide the substrate as it passes through the extrusion die and between the two rollers. An installation can include in line the extrusion die and the marking device.

Aerodynamic microstructures having sub-microstructure are disclosed herein. One disclosed example apparatus includes an aerodynamic microstructure defining an external surface of a vehicle, and a pattern of sub-microstructures superimposed on the microstructure to convey a representation of an image.
