Abstract: A device for the manufacture of elastic springs for spring interior mattresses, vehicle cushions, cushions and the like. The springs are constructed from a row of continuous, spiral shaped parts arranged after each other. The device comprises a feeding tool (18) for the spring wire (6), a bending tool (20) for the wire adjustable in a plane essentially perpendicular to the feed direction of the wire, and a spring shaping tool (21), which can consist of two parallel plates between which the wire runs during the manufacturing of the spiral shaped parts of the elastic spring and which are turnable for the adjustment of the slope angle of the spring part. At least one gear transmission (22), which especially can be a planetary transmission, is arranged for the adjustment of the spring shaping tool (21) in predetermined rotational positions.
