This disclosure presents methods and/or processes for forming a garage door faade using variable pressure. The forming processes, different from common stamping processes, creates a shaded design in a garage door section such that a continuous pattern is realized in the length direction (i.e., the longest side of the garage door section). The forming processes also produces significantly deep and smooth impressions that deform the center of the design. The forming process may be preceded by a texturing process, for example, each garage door section may first be textured and then sent for forming the design.

A method for producing a strip consisting of aluminum or an aluminum alloy for packaging purposes, in particular for cans, can lids or can closures, which provides an individualized aluminum strip for packaging purposes, with which decorative or identification elements can be reliably embossed without additional production steps being required, for example at the producer of the packaging means, is achieved in that decorative or other identification elements are embossed into the strip in the last rolling pass of cold rolling and in that the strip thickness is greater in the area of the decorative and identification elements than in the remaining areas of the strip.

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.

The present invention relates to a method for manufacturing a component of austenitic TWIP or TRIP/TWIP steel. A flat product (1) is deformed by achieving at least one indentation (16) on at least one surface of the flat product (1) in order to have in the deformed product (5) areas of a high strength steel embedded in a matrix of a ductile material. The invention also relates to the use of the component where areas of a high strength steel embedded in a matrix of a ductile material are required in the same component.

An embossing roll (1) having a cylindrical surface (2) comprising a central portion (3) having an embossing pattern (10) and side portions (4a, 4b) arranged on each side of the central portion, which are free from embossing pattern, wherein circumferential buffer channels (5) are provided on each side of the central portion (3), between the central portion and the side portions, along the cylindrical surface (2) of the embossing roll.

A rolled stainless steel object has surface with a raised and indented pattern including a random juxtaposition of at least two types of polygons. Each of the polygons has at least three sides, and is made up of substantially parallel rectilinear scratches, having a depth of from 5 to 30 ?m separated by ridge lines, the axes of which are from 0.1 to 0.3 mm from each other, and a Fourier transform spectral analysis of which, carried out on a square of at least 100 mm.sup.2, shows that they have an isotropy of at least 40% between the rolling direction and the sideways direction, and two adjacent preferred angular orientations of which scratches, from among the three main preferred angular orientations thereof, are spaced apart by a minimum of 20? and a maximum of 60?.

Provided are a manufacturing method for an embossing roll which is capable of being manufactured in a wide variety in small quantities and has uneven patterns formed uniformly and precisely without irregularities, and the embossing roll. The manufacturing method for the embossing roll comprises: a step of preparing a cylindrical base material; and a modeling step of modeling embossing onto a surface of the cylindrical base material with a three-dimensional printer based on three-dimensional processing data. It is preferred that the three-dimensional processing data is created by subjecting an embossing roll model to three-dimensional scanning.

The present invention relates to a method and a device for manufacturing plate part blanks for a heat exchanger. A sheet material (2) in the form of continuous sheeting is worked between two rolls (5, 6) with opposite surface patterns (7, 7, 8) to form profiled plate part blanks (3, 3,3) into the sheet material (2) so that the rolls (5, 6) are synchronized to rotate at substantially same rate by controlling the rotation of them in relation to each other with common synchronization gear (9), which gear is coupled to the rolls (5, 6) by means of shafts (10, 11) with disk pack or gear couplings.

A method of manufacturing bipolar plates includes passing a metal sheet through at least one tension roller disposed either upstream or downstream to a BPP forming roll to establish a longitudinal tension on the metal sheet as it passes through the BPP forming roll. A first pair of inner and outer lateral tension features are formed along a first side of the metal sheet and a second pair of inner and outer later tension features are formed along a second side of the metal sheet for use in establishing a lateral tension on the metal sheet as it passes through the BPP forming roll. The inner and outer lateral tension features in each of the first and second pairs have varying or different heights to advantageously provide a more consistent application of the lateral tension to the metal sheet.

A method for producing a metal sheet with raised lines uses a rolling mill including roll stands. In a preparing step, a grooved roll is prepared, the grooved roll including grooves. In a choosing step, a stand at least one stage before the last stand is chosen. In an incorporating step, the grooved roll is incorporated in as an upper roil of the chosen, specified stand. In a forming step, a workpiece is formed into a metal sheet with raised lines formed corresponding to the respective grooves. In the forming step, a maximum rolling reduction achieved by rolls of the specified stand is set to a provisional value that is lower than a required value. After the leading edge of the workpiece reaches the stand next to the specified stand, the maximum rolling reduction of the specified stand is changed to the required value.
