A method for manufacturing a magnetic sheet includes applying a roller having protrusions to a surface of a magnetic sheet to form recesses in the magnetic sheet. Functional regions having different degrees of compression are formed in the surface of the magnetic sheet by applying the roller.

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.

An apparatus and method for applying an EDT texture to an aluminum sheet has a rolling stand with at least one EDT surfaced roll capable of rolling the sheet at reductions<1%. The rolling is conducted with residual or no lubrication and imparts a texture on the scale of about 1 m to the surface of the sheet at low roll force.

The invention relates to a sheet metal plate (10) for creating flooring (30), in particular for industrial vehicles, having on its upper surface (11) a plurality or raised patterns, each raised pattern comprising one or more protruding portions (20), the raised patterns being arranged periodically, discreetly and in orderly fashion, the height h of the raised patterns being between 0.3 and 3 mm, characterized in that the plate has, on its lower surface (12), which is intended to be bonded to a support member, a rough surface the roughness Rmax of which is between 10 m and 250 m. The invention also relates to the method of producing said plate and the use of said sheet metal plate for creating flooring for industrial vehicles, preferably flooring for refrigerated vehicles.

Metal work rolls texturized with engineered textures can impart desired impression patterns on metal strips. Engineered textures can be controlled with particularity to achieve desired surface characteristics (e.g., lubricant trapping, coefficient of friction, or surface reflectivity) on work rolls and metal strips, and to allow for impression patterns to be imparted on metal strips during high percentages of reduction of thickness (e.g., greater than about 5% or greater than about 15%, such as around 30%-55%). Engineered textures can be applied by focusing energy beams at specific points of an outer surface of a work roll to impart texture elements on the work roll. In some cases, an engineered texture element that can be used to generate a generally circular impression element can be generally elliptical in shape, having a length that is shorter than its width by a factor dependent on the reduction of thickness percentage.

A method for manufacturing a friction lamella by way of the following steps: a steel sheet is supplied, which is provided with macrostructuring on at least one face, a friction lamella blank is separated out from the steel sheet and further processed into an annular lamella body.

A method of manufacturing a metal mask includes calendering a metal material, so as to form a metal mask substrate, where the metal mask substrate includes a surface and a plurality of grooves formed in the surface, and the grooves all extend in a direction. The surface has at least one sampling region, while at least two grooves are distributed in the sampling region, where an average area ratio of the area of the grooves within the sampling region to the area of the sampling region ranges between 45% and 68%.
