ABSTRACT:
A machine for coiling a sheet metal strip having a pair of lateral flanges joined by a channel shaped rib with oppositely opening lateral grooves where the rib is on the outside of the coil, includes a pair of cooperating fluting rolls between which the strip is fed to flute the flanges, one roll being circumferentially grooved to receive the rib of the strip, and a wedge shaped coiling shoe is positioned to receive the strip from the rolls. The shoe has three strip coiling ramps, two of which bear against the flanges and embrace the rib, and the third bears against the top of the rib. These ramps are positioned to deflect the strip into a coiled configuration. A pair of ears on the coiling shoe enters the oppositely opening lateral grooves and cooperatively with the fluting of the flanges prevents collapse or distortion of the grooves.
