Product Description
EAM-120 Spring Assembly Machine                                    

It can account the spring rows automatically.
It can pull out the inner-spring units automatically after finishing the enactment of the rows.
The spring rows can be enacted by the computer.

The machine operates without compressed air. Maintenance and spare parts wear is kept to a minimum. Production speed can be adapted to the quality of wire.

High flexibility
The EAM-120 assembly machine produces various types of spring units using springs with different diameter, wire thickness and height. The number of lines can be varied without moving the unused holdfasts.

The helix closing rings on both ends are very near to the springs. Exrremely precise, electronic controlled helix stop guarantees a perfect closing.


Control units are located on two panels,one of them can be oriented ,to help an easy machine set-up.


An innovative helix control device limits adjustment times in case of a collision. The system's high sensibility ensures an immediate stop without any deformation of the helix. Even the wire can not pull out due to wire tied or enwind, the device can immediate stop the mechine also.
