Wound filter-cartridges Type: PP, PPW (washed) Wound filter-cartridges are depth-filter-elements, produced in a special way of winding. Newest winding-machines guarantee a constant and high quality for filter-cartridges up to 60”. The PPW filter-element is wound with a special washed yarn. Washed yarn is free of wetting agents and prevents foaming.

Our fully automated winding centres for fine and self-bonding wire make us the perfect partner for any tasks you require. Our coils are tinned with lead-free coatings (RoHS). We can wind onto any desired coil form using many different press-in ferrite and metallic cores. Multiple tap coils are also possible. Pins are automatically applied to the coil connections during the winding process, with wire drawing electrically controlled. Our winding machines handle single-chamber and multi-chamber coils with wire thicknesses from 0.045 to 0.71 millimetres.

The specially developed production line can unwind, label, roughen, cut to length, strip, wind, bind and automatically deposit the cable wires. The material to be processed is unwound by a motorised unwinder and fed to a thermal transfer printer via a straightener. The latter prints the cable with two QR codes and a serial number. This ensures that each cable can be identified throughout the entire processing and manufacturing process and assigned to the stations which have already passed through. This traceability offers great advantages – for example in the diagnosis of faults. The cable then passes through a roughening station, which lightly roughens the material surface so that the connector overmoulding adheres better later on. An AM 3550 from Metzner Maschinenbau cuts to length and strips the cable, which is then transported to the winding station and onwards by a gripper to the binding machine. The latter winds the cable to form a cable ring.
