Apparatus for bias rolling of strip metal

Apparatus for rolling strip metal stock on the bias comprising:

• means for continuously forming strip stock into a portion of a cylinder and feeding it to a rolling station;
• means at said station of rolling said stock comprising at least one pair of rollers having relatively fixed substantially parallel axes mounted in journals in opposed relation to form a nip therebetween;
• means for driving at least one of said pair of rollers;
• means for moving said nip in a planetary path the radius of which is equal to the radius of said portion of a cylinder, the roller axes of said roller pair being located on the same radial line, said pair of rollers remaining fixed relative to one another throughout their movement in the planetary path;
• means for guiding said stock to said nip along a desired stock formation line;
• the axis of said rollers set so that said nip forms a bias angle relative to the motion of said stock and
• means for controlling the driven rotational rate of said rolls in relation to both the rate of the planetary motion of said nip and said bias angle of said nip, to draw the stock through said nip along the desired stock formation line.
