Tape stretching line Series AE
The tape stretching line serves for the production of stretched tapes made from PP (HDPE or mixtures of PP and HDPE only with special line version!!!)
The granulated material is fed to the extruder via a mixing and dosing unit. In the extruder the material is melt, compressed and homogenized. The pressurized material flows through an adapter and the filter to the flat die.
The film leaving the flat die is taken through a water quench where the temperature of the film is reduced for solidification of the material and to allow the further processing.
The subsequent cutting bar cuts the film into tapes of equal width.
The edge trimming device sucks the edge trims in on the central unit and feeds them to the grinder. Afterwards the cut edge trims are taken back to the extruder hopper. In the extruder the waste material is also melt for further processing.
The holding unit running at a higher speed than the film haul-off ensures the right film tension necessary for the cutting operation.
Between the central unit and the stretching unit the tapes are subject to a heat treatment in the hot air oven and stretched at the same time. The stretching forces are produced by the higher speed of the stretching unit.
For obtaining a textile structure of the tapes they can be fibrillated by means of the needle roller of the fibrillator.
Finally the tapes are wound up by winding heads each having a separate drive.

Extruder
The screw & barrel made of 38CrMoAlA and treated by nitriding guarantee long lifetime. The special design of screw keeps the reduced degradation and improved pressure constancy.
Different extruders (65/30D, 90/33D, 100/30D, 120/30D) can be combined with different down stream equipment for optimum investment and out-put capacity according to customers needs.
Automatic filter
Pressure and/or time controlled screen belt movement. 10 meters of screen belt ensure long continuous operation.
T-die:
Flex-lip die, working width from 700mm to 1500mm, can form uniform and thinner film.
Central Unit
Including quench tank made of stainless steel, film take-off, water removal system, slitting unit with manual cutting depth adjustment, holding unit and edge trim mill.
Hot air oven
Hot air oven with 4 m length to obtain optimum heat treatment of tape during stretching process on high-speed tape lines.
Stretching and Annealing Unit
This unit includes 7 godets chromium-plated (2pcs water-cooled) and 2 rubber-coated nip-roll. There are two drive motors for individual adjustment of stretching and annealing ratio.
Winding Unit
With electrical-magnetic tension control system, simple design and easy maintenance, the cam rod and transmission gear made of polyformaldehyde can be self-lubrication and long lift-time.
Electrical Control unit
The driving controlling system includes 2 pc DC drive controller & 3 pc AC inverter coming from Europe. The operation control system includes PLC from Japan, temperature controllers from Japan, synchronizing system, voltage protection system and so on. Adoption of best components from the world make electrical system reliable and high-performance.
