Coil winders - Import export

When you deal with industrial surface treatment and your expertise is the cleaning, brushing, polishing or coating of strip steel, you most likely do not want to spend any worries about the run of the material. That’s where our Winding Lines keep your worries away – because they take care of a safe run! They work with high tension and special monitoring and deflectors to do this, with the result of a clean wound beginning to end. The machine design thus calls for especially high drive power and precision expansion systems; even something so simple as the machine base is designed special to cope with the forces… To control the precision of one layer to the next, we utilize external edge controls and servo-drive the Reels for adjustment. This way we meet the typical low tolerances in this industry – after all, the coil is the product!

Most Winding Lines process one single coil (single-layer winding). There are however also applications where multiple layers are wound: With this process, the rewinding Coil Reel (Rewinder for short) reverses horizontally and orderly puts one layer beside the other, creating one long coil. This will make sense when narrow slit coil materials of small weight and – depending on their thickness – usually short running lengths would require frequent changeovers. Here, a layer-wound coil provides much longer productive time. The “elongation” by the way is done by butt-welding the coil strip ends. We offer this complete technology – including our own end-joining equipment and an adapted servo layering axis for the Rewinder. For thick strips we build vertical straighteners to correct the frequently occurring camber defect.

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). To manufacture self-supporting coils, we use self-bonding wire. During winding, the surface of the wire is bonded using hot air. To ensure the coil connections can be soldered, they are then stripped of insulating enamel using a fully automated milling process. PRUFREX is able to make air core coils with wire thicknesses from 0.045 to 1.6 millimetres.

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.

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). At PRUFREX, single-chamber and multi-chamber coils can also be achieved using two-wire windings. For specific magnetic flux requirements, we apply wires of different thicknesses to the coil form. Two different wire thicknesses, from 0.045 to 0.71 millimetres, on coil forms with press-in ferrite or metallic cores.

This motorized ring and drum winding machine is designed for winding coilable material such as cables, pipes, hoses, steel ropes, plastic profiles etc. either as rings or on spools and drums. With the appropriate components such as length measuring device and material cutter, the material can be measured and cut to length. The winding speed is adjustable at the operating desk by means of a rotary potentiometer. The frequency-controlled winding drive allows a smooth winding of the material. * other coiler heads and winding spools available on request
