Some of the slave material was very dirty from the transport, which is why it had to be thoroughly cleaned before it could be processed further. In order to simplify handling in the further process, the raw material was clamped into processing frames and automatically transported to the washing line after the incoming inspection. There, the external dirt was roughly rinsed off before the internal cleaning with body orifice probes took place.
Disclaimer: I'm posting a bunch of old renders here that I don't want to withhold from you. Since my 3D modeling skills weren't very mature at the time these works were created, I would like to apologize for the mediocre quality at the same time.
