The FPC-55 produces continuous strings of pocket springs.
The wire is fed from the swift and wound to springs. After the coiling process, the springs are heat-treated 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 ultrasound welding units then create the pockets. The resulting continuous strings of pocket springs are cut to the desired lengths in the cutting device.
