Abstract
An apparatus for manufacturing a metallic strip having a varying thickness which includes a supply means for providing a supply of elongate metallic feedstock, a pair of opposed forming rollers for working the feedstock in a cold condition, and a separation varying means for varying the separation of the forming rollers during operation thereby to vary the thickness of the feedstock and provide formed strip with a varying thickness.
Claims9
A forming roller arrangement which includes:
- a first forming roller which is rotatable about a first rotational axis and has first and second ends;
- a first bearing means for rotatably supporting the first roller, the first bearing means being located between the first and second ends of the first roller to provide an exposed end portion of the first roller at its first end;
- a second forming roller having first and second ends which is rotatable about a second rotational axis;
- a second bearing means for rotatably supporting the second roller, the second bearing means being located between the first and second ends of the second roller to provide an exposed end portion of the second roller at its first end;
- with the rollers extending in opposite directions with their exposed end portions overlapping one another and being spaced apart to define a rolling region between them;
- a first carrier in which the first bearing means is housed with the end portion of the first roller projecting therefrom;
- a second carrier in which the second bearing means is housed with the end portion of the second roller projecting therefrom;
- a support means for supporting the carriers in a relatively displaceable manner thereby to vary the spacing between the end portions, comprising a plurality of slide columns with one of the carriers being fixed to the columns and the other being slidable therealong.
