Abstract

1,174,233. Making heat exchangers; corrugating; bending; rolling. REDMAN HEENAN INTERNATIONAL Ltd. 15 Feb., 1967 [1 Feb., 1966], No. 4420/66. Headings B3A, B3E and B3M. A process for providing stretched forms continually along the length of a metal strip comprises continuously passing in tension the strip between first and second tensioning roller sets to continuously stress the strip at a value below the yield point and, progressively rotatably closing rotating mating male and female die members spaced apart a predetermined distance from one another in excess of the thickness of the metal strip and located between the tensioning roller sets, the male and female die members stretching said forms along the length of the strip. Strip 14 from a coil 16 passes between rollers 23, 24 of a first tensioning set 11, which serve to form longitudinal side channels 32, 33, then between rollers 18, 19 which form corrugations 34 in the strip between the side channels. The strip then passes between rollers 27, 28 of a second tensioning set 12 which serve to tension the strip below its yield point, between the sets 11 and 12, the rollers 18, 19 being so spaced and formed as to stretch form the strip over the ribs 40 of the roller 19 first between the set 11 and the rib 40, then between the set 12 and the rib 40. Two pieces of formed strip are secured together at 35, Fig. 2, to form a heat exchanger. Instead of corrugations separate dish forms may be produced in the strip.
