Definitions

  • This invention relates to tension levelling strip material, either ferrous or non-ferrous, and which may be either coated or uncoated.
  • tension levelling strip material either ferrous or non-ferrous, and which may be either coated or uncoated.
  • steel strip which has a surface coating e.g. galvanised.
  • Galvanised material which is classified as "full hard", that is high tensile quality sheet having sufficient ductility to be readily roll formed, e.g. into roofing profiles, has a minimum yield stress of 550 N/mm2.
  • a tension leveller for strip material in which strip is drawn under tension through at least one pair of co-operating rolls to disposal on opposite side of the strip and spaced apart along its length as to bend the strip along its path, the co-operating rolls being parallel faced over a major part of their length and tapered at one end, the tapers lying at opposite ends to one another and the rolls being moveable along their axes whereby the mutually parallel faces presented to the strip extend over a width variable in dependence on said movement.
  • the width of the mutually parallel faces is such as to lie just within the overall width of the strip so that the strip edges are aligned with the profiled portions of the rolls. These softer edges are thus subjected to less 'work' than the remainder of the strip, indeed the extreme edges may not be subjected to any working.
  • the axial adjustment of the rolls enables various widths of strip to be accommodated to suit particular order requirements.
  • galvanised steel strip 1 e.g, zinc or aluminium-zinc alloy coated
  • the tension leveller illustrated includes two sets of co-operating rolls 3a, 3b and 4a, 4b typically 30mm diameter over their parallel sections. As will be apparent from Figure 2 each of the rolls is tapered at the end, the tapered ends lying opposite one another.
  • the two rolls in each co-operating set are movable axially relatively to one another, like rolls in the two sets being movable in unison.
  • strip of different widths can readily be accommodated and processed in accord with this invention.
  • strip of maximum width of say 1650mm can be processed equally as well as strip of say a minimum width of 600mm with the rolls being moved away from one another along their axes so that their overlap is reduced in accord with this dimension.
  • strip gauges of between 0.2mm and 1.75mm may readily be treated in this fashion although of course thicker gauges may also be accommodated.
  • the tension leveller may incorporate only a single set of co-operating rolls or indeed more than the two shown and can also include conventional parallel faced rolls.
  • the tapered ends on the upper rolls on the one hand and the tapered ends on the lower rolls on the other hand need not be facing in the same direction as shown, they could be alternated.
  • a billy roll may conveniently be introduced between the two sets illustrated, but in any event there is no purposeful reduction in the gauge of the material exiting from the leveller as compared with the input gauge other than that experienced as a result of the 'stretching' action of the tension leveller; the thickness of the strip is substantially uniform across its width.
