The automatic spring coiling machine model ECL-70A produces Bonnell type spring from steel wire. It is completely mechanical and is operated by a single electrical motor. Electronic control systems further improved the quality of spring and its ease of use.
• In a single production cycle, the wire is coiled to spring, knotted at both ends and heat treated. The group of six conveyor arms moves the spring from a processing station to the other. When the production cycle is completed, the springs are collected in the outlet channel for stored. The operator no longer has to bend to collect the springs.
• The machine can shift from 5-coils springs to 6-coils springs for mattresses of different heights and features. It is also possible to shift from 5-coils to 4 coils springs to produce bendable mattresses, mattresses for children, or to be used in sofa. A different wire diameter can be used to achieve a different degree of rigidity of springs and spring units.
