Abstract

1379265 Stretching strip B W G BERGWERK-UND WALZWERK MASCHINENBAU GmbH 25 May 1972 [9 July 1971] 24802/72 Headings B3E and B3A A method of reducing strip comprises drawing the strip, under a tensile stress, through at least two sets 8 of bending rolls, each set having at least two bending rolls which are spaced apart from one another in the direction of movement of the strip, the bending rolls, or successive 'bending rolls of each set, being in contact with alternate faces of the strip, and the roll diameter of the or each succeeding set being less than the roll diameter of the preceding set. In the embodiment of Fig. 2, strip 18 is passed, via shears 3, welder 4 stressing stands 19, straightener 20 and accumulator 21, to a pickling bath after which the strip passes, via stressing stand 6 to six roll sets 8, the bending rolls 9-14 of which have diameters which decrease progressively from each set to the respective succeeding set. The rolls are mounted in the sets as shown in Fig. 3, the set shown in Fig. 3 differing from the sets of Fig. 2 in that the diameter of successive bending rolls 10a, 10b of the set decrease progressively. A motor driven roller 15 is provided between each set. Finally the strip passes, via straighteners 16, cold rolling stand 17, stressing stand'7, accumulator 23, stressing stand 24 and shears 5, to a take up reel 2.
