Abstract

A die body is provided defining a longitudinal channel therethrough including the cross-sectional shape of a metal stud to be cut and an opening is formed through the die body extending normal to the web of the channel and including a first arm portion extending along one longitudinal margin of the channel and a second arm portion extending from the first arm portion to a point spaced slightly inward of the other longitudinal margin of the channel, the first arm portion of the opening including opposite side portions thereof disposed inward and outward of the one longitudinal margin of the channel. The channel snugly, longitudinally slidably receives a metal stud therethrough with the inner and outer surfaces of the stud, except in the areas thereof registered with the aforementioned opening, backed by opposing surfaces of the die body and a cutting die is provided having the same cross-sectional shape as the cross-sectional shape of the opening and may be forced through the latter to cut away all portions of the metal stud registered with the opening.

Dependent claims

The method of forming an angle framing member from an elongated channel-shaped stud including generally parallel first and second longitudinal side flanges interconnected by a longitudinal web extending therebetween and from those opposite longitudinal margins said flanges are supported, said method including:

A. Cutting away a predetermined length of said first side flange to form an opening therethrough extending longitudinally of said stud and having opposite ends and a longitudinal mid-point spaced apart along the longitudinal extent of said stud;
B. Making a narrow transverse cut through said web extending from the longitudinal margin of said web corresponding to said first side flange and to a point immediately adjacent said second side flange and with the end of said transverse cut adjacent said second side flange spaced along said stud from said longitudinal mid-point of said opening;
C. Relatively angularly displacing the portions of said stud on opposite sides of said transverse cut about an axis normal to said web and substantially contained within said second side flange to positions with the portions of said web, disposed on opposite sides of said transverse cut, overlap engaged with each other and the portion of said first side flange defining one end of said opening abuttingly engaged with the outer surface of said first side flange spaced therealong from the other end of said opening, and;
D. Securing the overlap engaged portions of said web together.
