Abstract
A strip-bending mill is assembled from a set of interchangeable stages, each stage imparting a particular curvature of the strip; a group of stages so assembled, stepwise bending a particularly wide strip or skelp into a tube. For bending a different width strip or skelp, a different group of stages is assembled, but usually including some of the previously used stages in different positions. None of the stages are adjustable. Particular simple construction features are able to be achieved.
