EAM-120 Mattress spring assembly machine

Economy
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. Width changes are rendered easier by the new shape of the hold fasts which are quickly positioned and perfectly arranged thanks to the special gauge. Changes in length are possible by selecting the number of rows on the control panel.

Quality
The helix closing rings on both ends are very near to the springs. Exrremely precise, electronic controlled helix stop guarantees a perfect closing. Thanks to the helix lubrication device coiling is smooth, 5/4 link age reduces slack to a minimum.

The automatic assembly machine model EAM-120 assembles biconic Bonnell springs. The springs are manually inserted and, at the end of each row, the operator presses the pedal and starts the assembling cycle. With a single operation the jaws are closed, the spring linkage helix is coiled than cut and bent at both ends automatically. When the cycle is concluded, the spring units are forwarded and the jaws are ready to receive more springs. The EAM-120 performances are excellent; it is a highly reliable and productive machine for spring units and mattress manufacturer.

The EAM-120 assembly machine is equipped with one set of jaws, to be chosen among those indicated in the tables above, the scheme shows the width of the spring units according to the number of hold fasts and the width of the jaws, to be positioned at the shortest distance. The pitch of about 8~10mm at a time by means of a spacer gauge. By way of example:

15lines x 22 rows with spring with an 90mm external diameter and using 88mm jaws
15lines x 24 rows with spring with an 83mm external diameter and using 88mm jaws
16lines x 30 rows with spring with an 67mm external diameter and using 80mm jaws

CONTROL PANEL
Control units are located on two panels, one of them can be oriented, to help an easy machine set-up. The diglogue unit stores all features.

HELIX CONTROL
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 machine also.
