ape Stretching Lines from LOHIA Starlinger Limited have been developed to
produce PP/HDPE tapes for many applications such as woven/knitted bags,
Flexible intermediate bulk containers, Carpet backing, Tarpaulins, Wrapping
fabrics and many more .
T
igh speed tape stretching lines
are the latest development and incorporate
state-of-the-art technology. The lines are
designed to meet the highest performance and quality
requirement with maximum efficiency and flexibility while using
minimum raw material and energy. The design incorporates the experience
gained over 20 years in production & processing of tapes and takes into
account the current market needs. The consistently applied modular
construction principle permits tailored adaptation or subsequent expansion to
meet any desired requirement.

The extruder with the help of Hi-Q computer optimized screw ensures optimum melt homogenization and
conveys the melt to the T-die. Universal screws are the best choice for special applications with extremely low /
high denier of tapes whereas Barrier screws are recommended for tape deniers used for normal sack
applications. The T-die features computer designed flow geometry for optimum mass flow distribution and
minimum gauge variation across the width. Other attractive features of the extruder are grooved bush feeding,
cold start protection, micro-processor based PID controls, melt temperature, back pressure indicator and
pneumatic movement of the extruder cart.
The water quench film cooling system has specially
designed suction pipes combined with wipers and
squeeze rubber rollers which ensure absolutely dry film
even at higher line speeds. A temperature controller is
provided for maintaining precise temperature of the
water in the water bath.
The slitter with oscillating knife pack ensures vibration-free cutting of film into tapes and extended utilization of
blades. Automatic screen changer with belt filter can be used in place of manual screen changer to
minimize stoppages of tape stretching line for want of screen / filter change. Movement of this belt filter is timer
controlled and rate of travel of the same is user adjustable. With automatic screen changer, six station
indexable slitter is recommended in place of single station slitter. Worn out station of this six station indexable
slitter can be shifted to a new station through manual operation of the indexing wheel while the machine is in
operation thus ensuring uninterrupted output.
The holding unit with amply proportioned normal godets and positively driven nip
rubber roller ensures slip free stretching of the tapes.
The hot air oven with independent blowers for upper and lower level tunnels, with
common heating and velocity control mechanism ensures uniform temperature
profiles of +/-1degreeC and air velocities of +/-0.5meter/sec over the entire heated
surface. This gives uniform tape quality over the entire operating width of the tape
stretching line.
The combined stretching & annealing unit has independent drives for
stretching and annealing. The configuration of godets can be arranged as per
requirements of the end products of the customers by providing a mix of normal, hot
and cool godets. The temperature of the oil heated godets is within +/-1degreeC. The
water cooled godets ensure constant normal temperature of the tapes arriving at the
Cheese winders.
The tape extraction unit with suction nozzle at
the exit of the holding unit and of the annealing unit
with piping upto the waste collection box and with
mounted suction blower is provided as standard.

OPTIONAL EQUIPMENT :
Three / four component dosing and mixing unit is used for conveying material proportionately as per programming to the hopper of the extruder. The unit utilizes screws for high metering accuracy.
Melt pump is used to neutralize the effect of surgings in the extruder and ensure uniform delivery of melt to the die. It reduces the denier variation in the machine direction.
Auto gauging die is used for adjustment of the die lip gap automatically based on the feedback from thickness gauge monitoring system.
Water removal system is supplied additionally on specific requests either for higher operating speed or for raw materials with tendency of carrying more water during processing.
Thickness gauge monitoring system in conjunction with auto gauging die is recommended to produce tapes with denier variation that are closely tolerated. The automatic profile controller takes input from the scanner and gives output to adjust the die lip thermal bolts to control film thickness.
Extended hot air oven is recommended for HDPE tape processing and for higher speed tapelines for uniform and proper orientation.
Additional stretching unit with three heated godets is recommended for the requirement of tapes with lower residual shrinkage.
Fibrillator unit is placed between the hot air oven and the combined stretching & annealing unit for production of fibrillated tapes. The needle roller has an independent drive. The needle bars of desired pitch can be user selected and are replaceable. The design also allows production of fibrillated and non-fibrillated tapes together.
In the centralized computer control system the automatic control of temperature with optimization and precise speed adjustment of drives of all the units is easily obtained. The computer performs other functions like the management of recipe and alarm, displays the trend of melt pressure /temperature in graphic or tabular form etc. All these parameters are located in the memory and can be recalled at any time.Fibrillator Unit
