Abstract: A method for producing a strip with width of two longitudinal edges, made of at least one first metallic or predominantly metallic material, and the region, across which the first material extends, is provided with a boundary area that extends in staggered manner between two longitudinal edges over the cross-section of the strip. The invention comprises the steps of a) combing strips of different widths, which contain the first material and which as such do not comprise a staggered boundary area between their two longitudinal edges, to form a first arrangement of strips having a staggered boundary area; b) complementing the first arrangement of strips by one or more additional strips to form a second arrangement of strips having a rectangular cross-section, and c) bonding at least the strips of the first arrangement of strips to each other by rolling.

Abstract: This invention describes both a method and apparatus to practice a method which produces a strip-like pre-material from metal using rollers which have a roll gap in which the metal strip is discontinuously rolled in successively steps between the same two rollers with the metal strip being also recalled, but the recalled section of the metal strip is shorter than the circumference of the rollers. In this manner the surface quality of the metal is improved, especially relating to stamping of coins and metals.

Abstract: Disclosed is a method for producing a strip the width of which is defined by the two longitudinal edges thereof, which is made of at least one first metallic or predominantly metallic material, and in which the region, across which the first material extends, is provided with a boundary area (38a, 38b, 38c) that extends in staggered manner between the two longitudinal edges (36, 37) over the cross-section of the strip. The invention comprises the following steps: (a) Combining strips (31, 32, 34) of different widths, which contain the first material and which as such do not comprise a staggered boundary area between their two longitudinal edges, to form a first arrangement of strips having a staggered boundary area; (b) complementing the first arrangement of strips by one or more additional strips (33, 35) to form a second arrangement of strips having a rectangular cross-section; and (c) bonding at least the strips (31, 32, 34) of the first arrangement of strips to each other by rolling.

Abstract: A method is described for producing strip-shaped input stock, especially from metal, which is profiled in subsequent sections either on one side or on both sides, by rolling a metal strip in one or more rolling steps. The method is characterized by carrying out the following steps: (a) tensioning the metal strip (16), (b) positioning the metal strip (16) in a rolling gap (13) that is defined by a roller (12) and a movable plate (67) relative the roller (12), and (c) positioning the plate (67) relative the roller (12). Steps (b) and (c) are successively or simultaneously carried out or are carried out in a timewise overlapping manner or in a successive inverse order, and step (c) can also be carried out before step (a).

Abstract: Set of building elements containing building blocks (1) having a body (2) in the form of a rectangular parallelepiped, whose underside is provided with recesses (5) and whose top surface is provided with projections (3) having a lateral surface in the form of a surface of revolution at the intersections of an imaginary square grid, the configuration being such that such a building block (1) can be connected in clamping engagement with another building block (1′) of the set of building blocks by engagement of its projections (3) in the recesses (5) provided on the underside of the other building block (1′). The invention provides that the set of building elements contains one or more building blocks (1) where the projections (3) occupy only a part of the intersections of the imaginary square grid.
