SPIRAL WINDER CN-2010 Because of the machine design there are limitations in the type of material that can be produced on the CN-2010. Because the CN-2010 is not equipped with pre-heater units prior to the yarn entering the twisting zone this machine cannot process with PPS or ultra high modulus PET monofilaments. This "Start-up Base Model" enables initiation of spiral mesh production at a reasonable price. The machine can produce standard spiral sizes as noted in technical data section, but it is also possible to process other spiral sizes of choice based on desired application. The range of potential applications for the various possible meshes covers a wide range and can be directed at belting products for the paper industry and food processing as well as the filtration industry. To put it simply: it will produce spiral mesh belt for use in conveying from section A to B or to act as a filter media. EQUIPMENT OPERATION: The monofilament is taken from the bobbin (DIN 250, DIN 335, DIN 355) through the unwinder arm and delivered to the pre-tensioner spring into the eye of the winder head. If necessary, the monofilament can be coated with a lubri- cant (oil, silicon) prior to entering the winder head. The next stage; the monofilament passes through a secon- dary winding device and the monofilament is wound onto a fixed mandrel. This winding is performed by rotational motion with the winding device wrapping the monofilament side-by-side in circular motion onto a specially designed stainless steel mandrel. At this stage the monofilament is formed into a spiral or coil. The yarn than passes through a two-zone infrared heating chamber for stabilization. After leaving this heat zone the monofilament enters the cooling zone and the thermally set spiral yarn comes off the mandrel and deposits itself into a container or tube for further processing into assembled spiral fabric con- struction. * Hot Air free shrinkage at 200°C WE RESERVE THE RIGHT TO MAKE TECHNICAL IMPROVEMENTS WITHOUT NOTICE.
