Original patent claim 1 Newly added reissue claim 12
1. A machine for automatically 12. A machine for
and controllably forming sheet metalautomatically and controllably
into panels for metal buildings forming sheet metal into panels for
having combined walls and roof metal buildings having combined
panels, at least a portion of whichwalls and roof panels, at least a
are arched or curved; the machine portion of which are arched or
comprising: curved, the machine comprising:
a) roll forming means for roll a) a plurality of metal
forming sheet metal material forming rolls arranged to form sheet
into a desired panel profile metal material into a desired panel
having a central bottom portion profile having a central bottom
between upturned lateral edge portion between upturned lateral
portions; edge portions;
b) shear means adjacent the roll b) a movable shear blade
forming means for shearing the adjacent said plurality of metal
roll formed panel; forming rolls, wherein said moveable
shear blade cooperates with an other
c) crimping means for severing implement to cut said
continuously crimping by bending panel;
small folds in the bottom
portion of formed sheared panel c) crimping rollers for
lengths fed through the crimping continuously crimping by bending
means to provide a curvature of small folds in the bottom portion of
the formed panels, the depth of said cut panel lengths fed through
the folds establishing the said crimping rollers to provide a
curvature; curvature to said formed panels, the
depth of the folds establishing the
d) panel curvature measuring curvature;
means for measuring the
curvature of bottom crimped d) a curvature gauge for
formed panels, and; measuring the curvature of bottom
crimped formed panels, and;
e) automatic digital control
means for controlling the e) a digital controller to
crimping means to vary the control the crimping rollers to vary
control the extent of curvature the depth of the folds produced by
of the formed panels by varying said crimping rollers to control the
the depth of the folds, the extent of curvature of the formed
automatic digital control means panels, the digital controller being
being at least partially at least partially responsive to
responsive to the measuring said radius [sic, curvature] gauge
means and a control input and a control input setting of
setting of desired curvature. desired curvature.
