ABSTRACT:
Apparatus for forming fins along a web of metallic material utilizing first and second opposed endless chains, and with the first chain adapted to support the web of metallic material thereon, and comprising a plurality of spaced-apart anvil links. The upper chain includes a plurality of spaced-apart links operating in registry with the base chain and including work-engaging, fin-forming lugs which enter the gap between mutually adjacent anvil links. The apparatus further includes a chain-deflecting idler roll which deflects the base chain arcuately away from its normal plane so as to effectively reduce the spacing between adjacent anvil links and create a web back-breaking zone for achieving a firm and solid crimping of that portion of the web forced thereinto by the fin-forming lugs.
