Publication number: 20220402011Abstract: 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.Type: ApplicationFiled: June 17, 2022Publication date: December 22, 2022Inventors: Narcis Rugina, William Spilchen, Jeffrey Sacks, Abraham J.

Patent number: 11351593Abstract: 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.Type: GrantFiled: September 13, 2019Date of Patent: June 7, 2022Assignee: Structa Wire ULCInventors: Abraham Jacob Sacks, Jeffrey Leonard Sacks, William Spilchen, Narcis Rugina

Patent number: 10760266Abstract: 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.Type: GrantFiled: July 25, 2018Date of Patent: September 1, 2020Assignee: Clarkwestern Dietrich Building Systems LLCInventors: Abraham Jacob Sacks, William Spilchen, Jeffrey Sacks, Narcis Rugina

Patent number: 7287356Abstract: A welded wire lathing material for mounting stucco plaster and the like onto a building frame. This lathing material comprises intersecting transverse and primary longitudinal strands substantially located in a first plane. It also comprises secondary longitudinal strands also substantially placed in first plane and closely spaced with, some of primary longitudinal strands, thus forming longitudinal slots located at predetermined spaced intervals extending across the lathing material. The slots are wider than the shaft, but narrower than the head, of fasteners predetermined for attaching the lath to building frames. The longitudinal and transverse strands are welded together where they intersect to form a rectangular mesh approximately located in the first plane.Type: GrantFiled: September 16, 2003Date of Patent: October 30, 2007Assignee: Sacks Industrial Corp.Inventors: Abraham Sacks, Jeffrey L Sacks, William Spilchen, Narcis Rugina, Harold R. Davis

Publication number: 20050055953Abstract: A self-furring wire lath comprises a mesh of transverse and longitudinal wires welded at their intersections. Stiffening trusses are formed by bent sections in the transverse wires and longitudinal wires attached to the shoulders of the bent sections. A barrier layer material is retained in the lath between the apex of the bent sections and the principal plane of the lath mesh. The barrier layer material has apertures that coincide with the intersections only at the bent sections to enable mesh size reduction without compromising the barrier layer but still allow the fabrication of the lath. The lath provides good embedment in the stucco, reduces cracking and wastage of stucco while remaining easy to work with.Type: ApplicationFiled: September 8, 2004Publication date: March 17, 2005Inventors: Abraham Sacks, Jeffrey Sacks, William Spilchen, Narcis Rugina, Harold Davis

Patent number: 6820387Abstract: A self-furring wire lath has stiffening trusses. In a preferred embodiment the lath comprises a grid of intersecting transverse and longitudinal wires welded at their intersections. Stiffening trusses are formed at bent sections in the transverse wires by first longitudinal wires affixed at the shoulders of the bent sections and second longitudinal wires affixed on the bent sections. A barrier layer is disposed between the first and second longitudinal wires. A building paper backing may be affixed to the barrier layer. The lath reduces cracking and wastage of stucco while remaining easy to work with.Type: GrantFiled: August 13, 2001Date of Patent: November 23, 2004Inventors: Abraham Sacks, Jeffrey L. Sacks, William Spilchen, Narcis Rugina, Harold R. Davis

Patent number: 6305432Abstract: The invention relates to metal wire mesh having a plurality of longitudinal wires and a plurality of transverse wires. The longitudinal wires of the mesh are provided with shaped areas wherein the moment of inertia of said shaped areas about the neutral axis parallel to the plane of the mesh is 90 percent or less of the moment of inertia of said shaped areas about the neutral axis vertical to the plane of the mesh. This substantially reduces the problem of curvature set when metal wire mesh is rolled for packaging or transport and attempts are made to unroll prior to use.Type: GrantFiled: December 5, 2000Date of Patent: October 23, 2001Assignee: Sacks Industrial Corp.Inventors: Abraham Sacks, Jeffrey L.
