Bending machines for wire or tape-forming materials, in particular for the manufacture of iron or steel concrete blocks

摘要

The invention is concerned with a bending machine for wire or strip in which the raw material is advanced through the machine step by step and, between each step, a bend is made by a mobile bending tool. The bending tool is driven through a linkage which incorporates a control that can be operated whilst the machine is working to make a continuous adjustment to the working stroke of the bending tool and thus to the angle of bend made.
