universal pocket spring machine

Description of operation

The FPC-90 produces continuous strings of pocket springs.

The wire is fed from the swift and is wound to springs. After the coiling process, the springs are held by the 4 star-shaped conveying arms and heattreated between two electrodes. This heat treatment relaxes the springs that have become tense from the coiling process and reduces the setting loss. Subsequently, they are cooled in the cooling channel by means of an air ventilator and then conveyed to the spring setting station.

The springs are compressed and inserted into the folded band of fabric, which comes from the roller and has been horizontally folded over a forming shoulder. The ultrasonic welding units then create the pockets. The springs are then decompressed and set upright in the setup station. The resulting continuous strings of pocket springs leave the machine for further processing. Cutting as an option.
