TWO-FOR-ONE TWISTER WINDER

The GS2000-E is the last generation of SIMA twister winder, designed under the two-for-one-twist principle for the production of twisted yarns and twines using natural and/or synthetic fibers in the range of 5,000 – 120,000 deniers.
The externally strong mono-block frame is well balanced and operates vibration free.
The covers assure low noise level, due to their high noise-proof efficiency and in accordance with the most rigid standards

All moving parts have been studied for optimal ease of operation allowing the GS 2000-E to operate at 3.500 rpm, with a standard production capacity of 7000 twists per minute and with a special version for light deniers up to 4000 rpm and 8000 twists per minute.

Thanks to new specially treated materials, the friction coefficient has been reduced to a minimum, allowing a constant specific tenacity of the yarn during the twisting process.

Starting from yarn spools or bobbins , this  machine is suitable for making spool from min. 4”x4” to max. 12”x12”, equipped with main A.C. driving motors, with mandrel – multiple type for the production of spools with tube – expansion type with link rods for spools without tube.
Screw boxes are available from 4” to 12” traverse.

The machine can be combined with AC2000 accumulator to work in line directly from extrusion line for monofilaments, cable filler and twine production.

The GS2000-E can be also used as take-up unit of Rope Layer Mod 200/4.

The main features of the machine are:

  • Main A.C. motor with speed change by means of digital control panel.
  • Motor with increased performances  according to IEC 34-2 regulation, which enables to save energy, increasing  the life of motor and bearings, with a lower noise.
  • Digital control panel with meter-counter for automatic stopping of the twister at achievement of preselected length of the spool.
  • Change machine twists direction S/Z through the operator panel.
  • Pneumatic opening of cover.
  • Inside lightening.
  • Electrical yarn braking device complete with additional braking with 5 pulleys.
  • Draw compensator.
  • Electric-electronic control board, incorporated inside the frame.
  • Sensor for the speed feedback, which allow to carry out a proportional/integrative control in order
    to increase the precision, compared to the set set-point. Moreover, it allows to further increase the machine safety by means of an interblock of the protection.
  • Modular PLC with Eprom extractable memory.
  • Alarm signal on the digital display, so to carry out a diagnosis of the status of the machine, as for example the intervention of the protections.
  • Possibility to connect to the PLC, using the serial communication, a supervision unity of higher level, for example a computer with proper communication card, to acquire the production/diagnosis data.
