SPIRAL WINDER FD-2010 The coiled monofilament dimension (major x minor axis) may be chosen according to the desired end use of the as- sembled mesh. The range of application for the spiral mesh conveyors is very wide and includes the paper industry, foodstuff, and automobile industries and many other appli- cations. The spiral mesh belt is also useful in the filtration industry as filter media for use in separation of solids and aggregates. With the capability to produce flat monofilament spirals, the FD-2010 will also produce very thin (low caliper) coils for making fine mesh spiral fabrics (micro) applied to serve the modern high-speed paper machinery. The rotational coiling speed can be regulated in a variable speed manner from 0 to 2000 rpm, or via a key-switch set on 1600 or 2000 rpm. EQUIPMENT OPERATION: For flat monofilaments, from the rotating supply spindle (torsion-free unwinding, standard yarn package types DIN200 or DIN250), the monofilament is led over the rotating unwinder to themonofilament removal motor. Then, the monofilament goes directly to the spring pressure brake, the monofilament oiler (per requirement) and the micro- limit switch to the winding head with a fixed mandrel. For round monofilaments, (DIN 335 or DIN 355 type pa- ckage) the monofilament is unwound directly from a fixed standing position using the mounted unwinding device. This is performed at a speed of up to 2000 rpm, according to the monofil diameter in use. For flat monfilaments the speed for unwinding a rotating reel must not exceed 1600 rpm for safety reasons. (Safety fail-safe with key operated switch.) The next stage; the monofilament passes through a secondary 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 spe- cially designed stainless steel mandrel. At this stage the monofilament is formed into a spiral/coil. The coiled monofilament is then passed 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/coils with precise spacing comes off the mandrel assisted by a take-off motor and deposits itself into a container or tube for further processing into assembled spiral fabric construction. * Hot Air free shrinkage at 200°C WE RESERVE THE RIGHT TO MAKE TECHNICAL IMPROVEMENTS WITHOUT NOTICE.
