LOFIL
LoFIL
The new ‘LOFIL’ range of SDW Machines are based on the
concept of central extrusion modules, which are combined
with different roller (godets) modules, to allow the production
of different Polypropylene yarn types such as FDY (Fully
Drawn Yarn) - MT (Medium Tenacity) and HT (High Tenacity).
FLEXIBILITY
The unique machine concept allows for unparalleled machine flexibility. The configuration of the machines can now
be changed quickly and easily, simply by changing the roller modules. The customer can change the product according to the market needs.
PERFoRMANcE
The ‘LOFIL’ range is designed for winding speeds upto 3600 m/min and for denier range from 100 to 2800. The same machine can produce fine/coarser deniers with low uster values and high tenacity. Production of yarns with different cross-sections is possible.
QuALITY
Components are sourced from proven international sources to ensure maximum reliability and performance.
POLYPROPYLENE FILAMENT YARN APPLICATIONS

EXTRUDER
a specially designed extrusion screw serves the purpose of homogenizing and consistent delivery of polymer aggregate through the barrel. an automatic screen changer and 3 component (polymer + 2 additives) dosing and mixing system are fitted as standard, but other types of filtration and/or dosing system are available on request. Due to compact size of spinning section, polymer color changing and the related wastage is reduced to minimum.
MELT PUMP
planetary gear type polymer melt pump ensures uniform pressure and flow through each of the spin-packs.
SPIN PACK
there are 8 spin-packs for each extruder, arranged for optimum utilization of space while allowing sufficient gap between filaments down the quench zone.
AIR QUENCH
a specially designed quench zone ensures an even and turbulence free cooled cross-air flow which quenches the extruded filaments uniformly. compact water pumping system keeps the quench air temperature constant.
SPIN FINISH
Spin finish oil is applied to the extruded filaments through dual type nozzle application system using special low friction ceramic nozzles. the quantity of oil is metered by precision gear pumps ensuring uniform distribution of oil.
OIL-DISPERSION JETS
High quality oil-dispersion jets distribute the spin-finish evenly around and within the yarn cross-section. Optimum application of spin-finish results in better filaments cohesion, static charge elimination and stable yarn path, for faultless quality yarn production.
GODETS
a collecting godet pair is provided below the spin-finish application zone.
upto four hot godet pairs form the stretching zone for drawing the filaments in stages. each godet is individually driven with independent motor and frequency inverter. Speeds and temperature of all godet pairs can be set and monitored from the Human Machine interface (HMi) console.
the final relaxation godet with its adjustable height is a distinctive design concept brought in with this machine for optimum winding tension.
INTERMINGLING
intermingling unit (iM) jets are provided after the stretching zone. the iM unit can be easily bypassed if flat yarn is desired for subsequent twisting.
WINDERS
LOFiL is supplied with automatic winders for 4 or 8 package winding on each side. automatic doffing cycle without any human intervention results in higher efficiency/output and also helps minimize waste of FDy.
a conversion kit can be provided for shifting from 4 packages winding to 8 package winding or vice-versa.
ELECTRONIC CONTROL PANEL
the process is controlled by a pLc based system. the HMi (Human Machine interface) is an industrial pc system which allows centralised monitoring, setting and storing of process parameters of both sides of the machine through user friendly
schematic diagrams. in the event of a computer failure a complete back-up and recovery system is also available.
