APPARATUS FOR MANUFACTURING A METAL FRAMING MEMBER

摘要

In one aspect, an apparatus for manufacturing a framing member can include a translation path for transporting a metal sheet. The translation path can include a translation axis, a first set of rollers, which can include a plurality of first bottom rollers and a plurality of first top rollers, the first set of rollers can have a first centerline, and a second set of rollers, which can include a plurality of second bottom rollers and a plurality of second top rollers, the second set of rollers can have a second centerline, line, where the first centerline and the second centerline can extend away from the translation axis at an angle in the direction of translation.

主权项

1. A method of manufacturing a framing member comprising:
creating a plurality of slits in two pre-web regions of a metal sheet, wherein the metal sheet includes the two pre-web regions, and two leg regions, each being adjacent to the two pre-web regions; expanding the plurality of slits in at least one of the pre-web regions of the framing member to form a web region, the at least one web region including a web element and at least one web void; and forming a tubular framing member from the metal sheet, wherein the framing member consists only of the metal sheet.
