Abstract
The spring interior,comprises springs,with different spring constants (hardness). The variation of the spring constant is effected by changing the average radius of the windings,between the central winding,and the two end rings,of each individual spring. With a spring winding machine,whose bending tools can be set and adjusted by software during the production, in this manner spring interiors,may be manufactured which comprises any amount of zones of differing hardness. With this, all springs,consist of wire with the same diameter, the same end ring,diameter and the same height, and the automatic manufacture may be effected without conversion of the spring interior assembly automatic machines.
