ways 138 and 140 on the press. The air cylinder is
adapted to move the die through the piston and piston

rial 78 is moving. When the die 94 is moving at the
same rate of speed as the strip 78, the press 130 oper

of the Ways 117 which are attached to the lower die
operation with cut-out portions 107 the ribs 64 will be
formed when the die is in the position shown in FIG
URE 10.
To allow the strip 78 to progress through the die after
the ribs 64 are formed, the slide 106 is provided carry

As the upper die block moves toward the lower die
block and from right to left, the punch 100 severs the
strip 78. Immediately after strip is severed, the die por~ '

What we claim as our invention is:
A building panel comprising a horizontal plate portion,
a vertical web portion extending downwardly from one
edge of said plate portion, a foot extending laterally from
the lower edge of said web portion, the material of said
Web portion directly adjacent the ends thereof being
ribbing is formed on the roll forming apparatus previ
shaped to form elongated vertical indented ribs extending
ously described by substituting an appropriate pair of rolls
substantially the full height of said web portion, but hav
in the apparatus, for the pair of rolls which form the
ing upper and lower ends spaced respectively slightly
longitudinally extending ribs 44. It will be noted that the 10 below and above the upper and lower edges of said web
ribs extend at an angle to the side edges of the panel 202
portion, said ribs being su?iciently close to the ends of
and also at an angle to the direction of ?ow of the metal
through the rolls. Thus when the ribs 200 are formed
the material is drawn or stretched. The ribs 44 extend
parallel to the side edges of the panel 22 and in line with 15
the direction of ?ow of the material through the rolls.
Thus, when the ribs 44 are formed the material is moved
laterally from the side edges to the ribs with no stretch
ing of the metal. Therefore, a wider strip of material is
required to roll the panel 22 than is required to roll panel 20
202 with each panel having the same lateral dimensions.
The panel 202 provides stiffening ribs with the use of less
material than used with panel 22. The plate portion of
the panel is supported so that the ribs 200 are actually
drawn, with resultant stretching and thinning of the metal. 25
The drawings and the foregoing speci?cation constitute
a description of the improved building structures in such
said web so that the material of the Web between said ribs
and the ends of said web is displaced inwardly and the
material of said ribs thereby being of the same thickness
as the remainder of said web.
