Abstract

1301667 Making corrugated strips ASSOCIATED ENG Ltd 5 May 1970 [9 May 1969] 6154/72 [Divided out of 1301665] Headings B3A and B3E The subject matter of this specification is identical with that described in Specifications 1,301,665 and 1,301,666, but the claims are concerned with a punch and die 17 and 20 which co-operate with an already forming corrugation to clamp the strip and to form either a partial or complete louvre while a further corrugation is formed by a punch and die 11 and 10. In another embodiment the punch and die 11 and 10 form a corrugation and a completely formed louvre while the punch and die 17 and 20 serve to locate the corrugated strip.
