Abstract

This invention relates to an apparatus for the forming of wire, namely a leg or spiral spring winding and bending machine. It is an object of the present invention to reduce the expenditure for the production of the apparatus and to universalize the forming operations which can be carried out with each tool. The apparatus including a plurality of tools (86, 88, 90, 92 or 142; 162, 190, 192) on a tool holder (74; 160) which is fixed at the free end of a longitudinally displaceable shaft (12) resembling the known winding spindle and is replaceable. Every existing tool can be brought into the pathway of the wire and hence into operation by positioning the shaft by rotation and longitudinal displacement by means of a drive which is known from the conventional winding spindle but differently controlled. The advantage of this apparatus is that it is of simplified construction and enables the same tools to be used for producing different forms of springs.
