    8. The 12 AC motors run with max. 86 cycles, corresponding to 1200 m/min
    9. Transmission between motor and driven elements is done by means of timing belt drives
    10. Texturing aggregates are single motor driven and arranged in 2 decks; they are inverter controlled for each deck and each machine side
    11. All AC motors controlled via Barmag Beltro-Vert-D system
    12. Speed regulation via microprocessor system Beltro-Cont which calculates machine settings such as machine speed, D/Y ratio, crossing angle, ribbon breaking, stroke modification, etc. into motor rpms or machine speed
  5. Yarn Control
    1. Yarn cutter: installed before first feed system, works electromechanical; cuts and clamps the yarn ends in case of yarn breaks; must be opened by hand to enable the cutting function; after response, the yellow actuating pin projects and signals a yarn break; collective yarn cut in case of power failure to prevent damage to PU discs (PU switchoff) is included in the delivery scope
    2. Yarn sensor (non-contact yarn sensor): installed in lower position between third feed system and oiling device; gives electrical impulse to yarn cutter in case a yarn end is missing
  6. Heater
    1. Primary heater: Dowtherm heated; 6 four-grooved heating plates for one field section form one complete system; fume exhaust nozzles at the upper part of the heating plates; length of heating plate: approx. 2000 mm; deep V-groove of 11 mm depth with additional pinches to prevent yarn heat outs
    2. Secondary heater: Dowtherm heated; one heater unit includes two independent systems for A- and B-side with 12 yarn tubes each; each position is equipped with an exchangeable tube which can be removed for cleaning purposes for which the unit is swivel-mounted; length of tubes: approx. 1460 mm; inner diameter: approx. 3.8 mm; at the lower end of the tubes there is a centering for the yarn suction injector
    3. Control system: Beltro-Loop digital control via PT 100 measuring sensors; temperature setting and indication by microprocessor system Beltro-Cont; one control loop per heating system, i.e. 18 per machine for the upper Dowtherm heater and 18 per machine for the lower Dowtherm heater
    4. Temperature setting: menu-guided data input and output via PC keyboard and color monitor; pictorial display of the heater status and alarm signal on the display screen whenever the preset limit values are exceeded; alarm signal in case that temperature limits are exceeded
  7. Cooling Zone
    1. Cooling plate of approx. 1100 mm length, cooled by ambient air
