Plastic films (PET is a common material) are widely used in window pasting packaging and baking industries, especially with the recent development of the domestic baking industry, the printing is becoming more and more exquisite, and the packaging value is becoming more and more upgraded.

Due to the production of plastic films using a casting process, the thickness is thick, and the thickness uniformity of the material is poor. The number of unfolded meters per roll is limited, and the control accuracy of printing tension is extremely high. It is precisely because of these characteristics that the introduction of a non-stop system is more important when producing the above materials on a flexo printing machine. This is perfectly solved by the special unwinding secondary tension of DYM Machinery's non-stop machine.

Of course, it is because of the thick thickness and strong toughness of plastic sheets that the introduction of a automatic turret rewinder system in the rewinding process often poses significant challenges when the material is cut off instantly to replace another air shaft. Therefore, another rewinding solution of the DYM Machinery non-stop system can successfully solve this problem and bring brilliant results to customers. Its production capacity has increased by 200%. Moreover, under the same production capacity, the additional production capacity has not increased the electricity cost, which makes customers extremely excited and affirms the clever move of investing in the non-stop system.

The secret of automatic unwinding is to use the HAU non-stop unwinding system, which has been specially improved. In the non-stop state, due to the presence of the storage rack, a full roll of unwinding shaft can be smoothly replaced on another unwinding shaft at 0 speed. Therefore, the shortcomings of ordinary turret automatic switching are precisely solved by the improved HAU unwinding machine.

A、 For the prepared unwinding shaft, it is necessary to prepare a section of residue from the receiving unit to the paper tube on the unwinding shaft in advance, and apply adhesive tape at the designated position.

B、 This pre prepared residue is about 3 meters long. After being produced on the printing machine production line, it is always difficult or impossible to use up the entire roll of material on the next die-cutting production line, resulting in waste. The reason for this waste is that when the material at the unwinding station of the die-cutting machine is used up, there is always a distance of 2-3 meters from the paper tube to the receiving station or to the correction receiving station, but the production line needs to be stopped because it is always impossible to use the material at the receiving station to save waste when the material leaves the paper tube. In this state, tension control will be lost. It is precisely for this unchangeable reason that almost all manufacturers always default to the seemingly small waste of about 3 meters at the die-cutting station. However, the 2-3 meters of material at the paper core of the improved DYM Machinery non-stop HAU unwinder just saved about 3 meters of high-quality products wasted during each roll production.

C、 It is precisely by improving the process characteristics of the HAU unwinding machine that the paper core is made up of artificially prepared residues, so there is no bulging phenomenon, ensuring that every meter of material is of excellent quality.
