Abstract: The invention relates to a formwork ribbed metal profile member assisting in the construction of metal/concrete flooring, including longitudinal edges (2, 3) defining upper (4) and lower (5) areas connected by webs (6) and comprising recessed deformations, characterized in that at least a portion of each web comprises a recessed deformation (60) defined by a continuous line which extends parallel to the longitudinal direction of the profile member, and the length of which is greater than that of said portion of the web in said longitudinal direction.

Abstract: The use of shafts of small diameter in profiling heads gives rise to problems of bending and of loss of adjustment. In addition, the runout of the shafts can cause them to be ejected. To remedy these problems, the invention provides anti-bending means securing together shaft adjustment and forming means. A profiling head (1) of a profiling machine includes at least one forming cassette (2) including a set of two parallel shafts (20, 30) having wheels (201 to 217; 301 to 310) separated by spacers (200; 300) mounted thereon to form rolling tooling, and a frame including uprights (41, 51) for supporting the shafts (20, 30) and a base (60), which uprights are provided with vertical adjustment means (44 to 46; 54 to 56).
