Abstract

1,196,512. Detering physical structure; straightening; tensioning. PRESSED STEEL FISHER Ltd. AND DAVY & UNITED ENG. CO. Ltd. 24 Feb., 1969 [27 Feb., 1968], No. 9378/68. Headings B3E and B3V. Apparatus for processing metallic sheet or strip material having a discontinuous yield point includes a set of work rolls, means for applying pressure therebetween, and means for applying tension to the sheet or strip entering the work rolls whilst avoiding significant tension in the sheet or strip emerging from the work rolls, the set of the work rolls comprising a single roll 21 having a resilient or soft peripheral surface co-operating with one or more relatively hard rolls 22 and the arrangement being such that when the sheet or strip is passed between the work rolls it is so flexed that the yield point is suppressed. The apparatus includes a decoiler 11, a mill 12 housing the work rolls 21, 22 and a roller leveller 13. The decoiler has two truncated cone members 16 one of which is driven by a motor (not shown) to feed the strip or sheet into the mill whilst the other is provided with a disc brake 19 which resists the uncoiling of the strip or sheet and subjects it to sufficient tension to control its tracking through the mill. The speed of the resilient roll 21 is controlled by limit switches 25 which ensure that a loop of processed strip or sheet is maintained between the mill and the leveller thereby ensuring there is no tension in the strip or sheet emerging from the mill. The mill includes idle pinch rolls 20 which may be provided with a disc brake and the decoiler is then not required.
