A baseboard element including a nose portion, a riser portion, and a wall groove portion coupled to the riser portion. The nose portion includes a nose bottom section and a nose face section. The riser portion includes a riser section extending approximately perpendicular to the nose bottom section and a riser bend coupled to the nose portion. The riser section is substantially planar and defines a plane. The nose portion is positioned only on a first side of the plane defined by the riser section, and the wall groove portion is positioned only on a second side of the plane, the second side opposite the first side. The nose bottom section comprises a nose bottom edge at a terminal end of the nose bottom section. No structure of the baseboard element extends beyond the terminal end of the nose bottom section from the terminal end. The nose bottom edge of the nose bottom section is either approximately at the plane or closer to the plane than the nose face section is to the plane. Other embodiments are also provided.

A mold for a press brake includes an upper mold that is mountable on an upper table and a lower mold mountable on a lower table in a press brake. The upper mold and the lower mold vertically face each other and have respective pressurizing surfaces. The respective pressurizing surfaces are superposed with each other in a pressing direction so as to define a wedge shaped recess between the respective pressurizing surfaces. The respective pressurizing surfaces are configured to pressurize a workpiece positioned between the respective pressurizing surfaces. Further, one of the pressurizing surfaces is formed as a level surface and the other is formed as an inclined surface. The upper mold includes a V-shaped workpiece bending portion that can freely enter into a bending groove provided in the lower mold, and the respective pressurizing surfaces are positioned outside of the bending groove of the lower mold.

A foldable mounting collar includes first and second collar segments. Each collar segment includes a planar annular segment that substantially subtends a semicircle, a collar flange that, when the planar annular segment is horizontal, extends vertically downward along an inner periphery of the planar annular segment, such that the collar flange forms a cylindrical portion, and two hinge flanges that, when the planar annular segment is horizontal, extend upwardly from each end of the semicircle formed by each planar annular segment. The mounting collar further includes pivot means that hingedly couple pairs of the hinge flanges of the collar segments. The second collar segment can rotate, relative to the first collar segment, through at least a polar angle range sufficient for the mounting collar to fit through an aperture having a diameter defined by the cylindrical portions of the collar flanges when both collar segments are horizontal.

A baseboard element including a nose portion that includes a nose bottom section, a nose top section extending approximately parallel to the nose bottom section, and a nose face section extending between the nose bottom section and the nose top section. The baseboard element also can include a riser portion comprising a riser section extending approximately perpendicular to the nose top section, and a riser bend extending between the riser section and the nose top section of the nose portion. The baseboard section additionally can include a wall groove portion comprising a groove front section extending approximately parallel to the riser section of the riser portion, a groove back section extending approximately parallel to the groove front section, a groove bottom bend extending between the groove front section and the groove back section, and a groove top bend extending between the groove front section and the riser section of the rise portion. Other embodiments are provided.

A method of aligning a flat or profiled metal sheet with preformed notches on the two sides of the metal sheet when the sheet enters into a bender or folding machine directly from a roll forming machine linked or joined to the folder. The metal sheet has to be effectively aligned on the folder before folding to avoid potential damages to the metal sheet of not being properly squared or angled on bending while reducing the times to produce the folded products. Moreover, this method according to the invention allows the metal sheet to feed directly into the folder from the rollformer without having to pass through an intermediary transfer table or aligning device/machine before entering the folder for folding or manual alignment in the folder.

A formed body 1 includes a first flange 3, a body portion 100 (a first vertical wall portion 4, a top plate portion 5, a second vertical wall portion 6), and a second flange 7, and the formed body 1 is made of steel having tensile strength of 440 MPa or more. The first flange 3 extends toward the second flange 7 from an edge portion of the first vertical wall portion 4. The first flange 3 and the body portion 100 curve so as to conform to each other as viewed from the direction orthogonal to the top plate portion 5.

The bending machine (100) has an upper beam (211) and a lower beam (212), each of the beams (211, 212) having a clamping element extending therefrom adapted for clamping an elongated flat sheet metal workpiece (218) with a portion extending from the machine in cantilever fashion. Bending tool carriers (221, 222) having a bending tool (223, 224) extending therefrom are movable relative to the beams so that the bending tool (223, 224) can extend and pivot to form an elongated bend in the workpiece (218). A plurality of wedges (251, 252)are selectively extendable between the beams (211, 212) and the carriers (221, 222) to provide uniform depth of the bend in the workpiece (218) along the length of the bend, the depth of extension being adjustable with ball screws (261, 262) attached to synchro or servomotors (265, 266).
