Ankerwerk Nürnberg i need help

Hello everybody, i new on Forum and also new in Plastic injection profession.
I hope someone will be able to help me and I will try and give it up for it.

I started working with the injectors some six months ago. At the moment I have 3 machines by Dr.Ing.Sommer, Arburg 300 P R and Ankerwerk Nürnberg. I understand some machines and somehow I get them into work, but I have a problem with Anker machine. It does not make me realize how the injection and dosier principle works. So I can not let it go. I will become a picture of a machine, if anyone accidentally knows what a principle it is and how honest I would be very grateful if she could explain it to me. I hope someone can help me. Thanks in advance and apologize if I did not write a good thing about my English does not go very well. thank you very much for the greeting.
