Abstract: A rolling mill machine is for longitudinal bending of plate to selectively provide one of at least two cross-sectional profiles. The machine includes a plurality of shaping stations extending transversely of the plate with at least one drive station for advancing the plate through the plurality of shaping stations. Each of the shaping stations has a first forming element on one side of the plate and a second forming element on the other side of the plate. The first forming element has at least a first set of non-driven forming rolls and a second set of non-driven forming rolls. The second forming element has a plurality of non-driven forming rolls. The first forming element is selectively moveable to position at least one of the first and the second sets thereof for bending of the plate. The rolls of at least one of the first set and the second set are disposed for forming the plate on one side and the rolls of the second forming element are disposed for forming on the other side.

Abstract: A framework cassette of thin sheet intended to be joined to adjacent cassettes so as to constitute a lost form when casting concrete framework and co-operating with the concrete in the finished framework as regards the absorption of forces. It consists of a rectangular bottom (11) along the two longitudinal sides of which edge beam sections are bent up. These edge beam sections consist in part of an upper, horizontal flange (5), a vertical web (3) with bulges (8) and furthest down a sleeve (6). On the sleeves (6) and between them is located a top section (9) which is also secured to them. The space between the top section (9) and bottom (11) of the cassette can be filled with insulation or used for installation material (14). The concrete is cast over the top section (9) and between the webs (3).

Abstract: An elongated safety bar comprises first and second spaced apart flanges and first and second webs which interconnect the associated side edges of the first and second flanges, the second flange, when viewed in cross section, including a flat central portion, and the first flange, when viewed in cross section, including a central portion which is parallel to the flat central portion of said second flange, and opposite generally semicircular end portions, these end portions extending away from the side of an imaginary plane defined by the flat central portion of the first flange opposite the side facing of the second flange. The second flange is longer, viewed in cross section, than the first flange, thus providing the safety bar with a closed, generally trapezoidal-shaped cross section.
