RAFFIA TAPE STRETCHING LINE

Heaven Extrusions offers a complete line of Tape Extrusion Lines for High Quality Universal Processing of PP/HDPE Tapes for a wide range of applications including FIBC / Jumbo Fabrics, Woven Bags, Geo and Agro Textiles, Carpet Backing, Fibrillated Artificial Grass, Wrapping Fabrics, Tarpaulins Ropes, Twines, and many others. Our high-speed tape stretching lines are of premium quality, with one-level-up technology and low cost. Our machines have a great price-to-performance ratio (Best in Class), and they comply with all current international requirements. For maximum efficiency, these are produced according to the needs of the customer.

Based on the stretching mechanism, we provide two different series of tape lines. The T-Rex Series provides traditional single-stage stretching, while the duo stretch series provides two-stage stretching, in which the tapes are stretched first before passing through a hot air oven for final stretching, which improves process stability and ensures smooth, efficient, and high-speed working for the best tape properties.

Raffia Tape Stretching Plant Optional Equipments

Dosing and Mixing Unit

Melt/Gear Pump

Melt pump is used to neutralize the effect of surging in the extruder and ensure uniform delivery of melt to the die. It reduces the denier variation in the machine direction.

Extended Hot Air Oven

Extended hot air oven is recommended for HDPE tape processing and for higher speed tapelines for uniform and proper orientation.

Bigger Size Hot Plate

Extended hot air oven is recommended for HDPE tape processing at higher speeds for uniform and proper orientation.

Additional Stretching/Godet Unit

Additional stretching unit with three heated godets is recommended for the requirement of tapes with lower residual shrinkage.

Fibrillator

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.

Centralized Computer Control Unit with HMI

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 displays the trend of melt pressure/temperature in graphic or tabular form.

Raffia Tape Stretching Plant Salient Features

Extruder

Screen Changer / Melt filtering device

Continuous screen changer, online melt filtration without stoppage of the line minimizes the wastage, downtime & number of stoppages, giving consistent denier and increased productivity. It has unique feature of giving alarm at screen/filter chock-up.

Extrusion T-Die

The Coat hanger type T-die features optimum mass flow distribution and minimum denier variation across the width. The special configuration of the dies with higher cross sections gives increased heat inertia and power saving and melt flow channels inside the die give optimum melt distribution. The surface of the final product can be varied by the use of smooth or profiled die lip. Hard chrome plated, mirror finish melt channels in the die and outside die surface is flash chrome.

Water Quenching Tank

Stainless Steel fabricated water quench Tank. Unique Water tank flow management for uniform quenching of the film offers minimum turbulence for the film, which is being cooled and the water level can be adjusted relative to the die. A temperature Indicator is provided for maintaining precise temperature of the water in the water bath.

Film Take – up

Precisely machined, Optimized film take-up with Nip Roller, designed for low and high denier tapes. Take off unit equipped with specially designed water removal system from the film, ensures drying of the film at high operating speeds to avoid water carrying.

Film Slitter

We supply Six station index able slitter, ensures vibration-free cutting of film into tapes and extended utilization of blades. Worn out station of this six station index able slitter can be shifted to a new station through manual operation of the indexing wheel while the machine is in operation thus ensuring uninterrupted production and reduced wastages. It comes with very precisely grinded metal Spacers of your size.

Holding Unit / 1st Godet Unit

Holding unit is of rugged movac design for longer life and vibration free operation. Mirror finish, hard chrome plated 320mm diameter rollers make it easier to operate at high line speeds. It’s positively driven nip rubber roller ensures slip free stretching of the tapes. AC frequency variable drive fitted for energy saving and batter control.

Edge Trim Recycling Unit

Side trim are pneumatically conveyed to a large shredder and the ground flacks are conveyed to the extruder through a cyclone separator. Lowest Power consumption among in class. Innovative technology for lowest power consumption and lowest maintenance cost. Unique side cutting design for guaranteed cutting.

Hot Air Oven

The highest energy efficient Hot Air Oven with independent blowers for upper and lower level air circulation is characterized by extremely uniform temperature profiles of ± 1°C and length up to 8 meters for Better Heating of the tapes at higher line speeds and at higher outputs. This gives uniform tape quality over the entire operating width of the tape stretching line. Ceramic fibre insulation on all sides to Prevent Heat Loss. Innovative and ahead than rest, up to 40% Energy Saver, Dual Heating System – Electric Heating and Gas (LPG / PNG) heating.

Combined Stretching & Annealing Unit / 2nd and 3rd Godet Unit

Combined stretching and annealing unit are of rugged movac design for longer life and vibration free operation. It is designed for maximum operating speeds of 400Mtr/min .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 water cooled godets ensure constant normal temperature of the tapes arriving at the Cheese winders. Our Tapelines are with AC frequency variable drive for energy saving and batter control.

Tape Extraction/Aspiration Unit

The concept of combined vacuum suction box for first and discharge side of second godet is accomplished for power saving. The tape extraction unit with suction nozzle at the exit of the holding unit and of the annealing unit with piping up to the waste collection box and with mounted suction blower is provided as standard.
