ABSTRACT:
A portable bending machine has a boxlike casing with an internal support structure fastened to its top plate only. A reinforcing steel rod is bent around a fulcrum roll by a bending roll revolving about the fulcrum axis, while an adjustable abutment on the top plate of the casing bears against the work. The bending roll, the fulcrum roll, the abutment, and a drive mechanism for revolving the bending roll about the fulcrum roll are all mounted, either directly or via the internal support structure, solely to the top plate of the casing. Consequently, all but the top plate of the casing walls can be made thinner than heretofore.
