A turret roll forming machine includes at least one turret assembly carrying multiple rows of tooling (e.g., forming rollers), rotatable about an axis to selectively align rows of tooling with an input or output. A transmission is accessible from an exterior of the turret assembly without disassembling of the turret assembly to perform a changeover of roll tooling and/or maintenance on gears, bearings, or shafts of the transmission. Thus, a chain drive may be employed, advantageously accommodating differing rotational speeds for top and bottom forming rollers of each pair of forming rollers, e.g. to reduce roll scuffing. Pairs of forming rollers may be provided as cassettes, which are removably coupleable to the turret assembly allowing quick and easy reconfiguration and/or servicing, minimizing negative effects of changeover. The turret assembly may be a unitary structure (e.g., a weldment) improving rigidity and increasing accuracy of roll forming operations.

Expanded metal formed using rotary blades and rotary blades to form such
A rotary slitting blade for fabricating expanded metal products includes opposed end surfaces and an outer circumferential surface extending from one of the end surfaces to the other of the end surfaces. A plurality of notches are formed in each of the end surfaces. The notches include curved surfaces having convex curvatures that smoothly transition into one of the end surfaces and/or the outer circumferential surface. The rotary slitting blade improves the quality of a resulting expanded metal product by reducing or eliminating tears, cracks, and fractures in the expanded metal product.
A stud such as a light-weight metal stud can include a first elongated channel member and a second elongated channel member coupled to the first elongated channel member by a wire matrix, where ends of the wire matrix are located at ends of the first and second channel members. A pitch of the wire matrix can vary over the length of the stud. Two or more such studs can have different lengths where a difference in the lengths is not a multiple of the pitch.

A light-weight metal framing member includes a metal stud and reinforcement plate(s), and method to produce a light-weight metal framing member may include forming a pair of channel members each having a respective major face having a respective first edge, and reinforcing such with one or more reinforcement plates, preferably at opposed ends thereof. Each member includes first and second flanges extending along the respective major face. A wire matrix includes a pair of wires each having apexes alternatively physically attached to the pair of channel members. The wire matrix forms longitudinal passages to support utility lines and position the lines away from the pair of channel members. The apexes are secured to flanges of the pair of channel members to strengthen the stud and reduce weight.

An expanded metal lath may be formed by slitting a metal sheet or strip in a defined pattern and subjecting the sheet or coil to a tensile force sufficient to cause the slits to form a plurality of openings. The web bands forming the plurality of openings can include a heavier web bands in areas where fasteners will be used to affix the expanded metal lath to a substrate and lighter web bands in other areas where fasteners will not be used. The expanded metal lath can include stabilizers or selvedge wires at opposed lateral or longitudinal edges to protect the expanded metal lath during shipping and installation. The expanded metal lath may include furring elements integrally formed with the web bands to raise the expanded metal lath off an underlying surface.
