LEO Machinery 2009 - 2 - 07-2009 THE FD-1600/UVS: In addition, and independently from each other, left and right spirals can be produced. Due to the fully automatic method, it is ensured that the spirals produced are equal throughout for further processing into dry or wet felt for the papermaking industry, filtration industry as well as conveyor belts for all kinds. Full automation means that one person can operate and supervise 10 to 12 winding machines. METHOD: From the rotating supply reel (torsion-free unwinding, standard layout DIN 200/250 = 2.5/5.0 kg reel) the monofilament is led over the rotating unwinder to the monofilament removal motor. Then, the monofilament may either be led over the adjusted preheater or directly to the spring pressure brake, the electronic filament tensioning with display, the monofilament oiler (per requirement) and the micro-limit switch to the winding head with a fixed mandrel. For round monofilaments, 10kgs reels (DIN 335) or 20kgs reels (DIN 355) may be used, but they can only be unwound when standing on the floor and by using the supplied unwinding device. This permits a speed of up to 2000 rpm, according to the monofil diameter, while the speed for unwinding a rotating reel must not exceed 1600 rpm for safety reasons; reel size DIN 200/250. (Safe guarding with key operated switch.) Through the rotating motion the monofilament is formed into a spiral and led to the guide channel arranged as moving part. Here, the spiral runs through a heating zone (contact heat). In the cooling section that follows, the adjusted removal motor can be set to regulate the pitch of the spirals. (Important for spiral joining.) The spiral runs then over a gliding device into the storage container ready for onward processing. To adapt the machine to a different spiral size, only a set of mandrels is needed. All other adjustments are made directly on the machine!
