rotary stems & roller portal

[Nioh17]

hello to everyone, I would need extra knowledge for designing rotary stems e roller portal in drawing them better. I would like to understand the creation (procedure and sequence processing) , it would be useful to have documents taken from correct sources and perhaps examples of technical drawings and guides with pdf/video file
Thank you.

Bye. Good question and I think you'll hardly find someone to unveil their business secrets.
the first drum is the one that is the largest one used on the embossers to give a plot to long ribbons, for example on the aluminum sheet or thin stainless steel to make the paper over yogurt or for the blisters of the tablets or to form the skin. for the second drum is that of the drum shears that serve to make cuts with continuous speed without stopping the tapes.

you will find information looking for "drum shear" or "flying shear".

This is the cut pattern:and these machines....com so much of synchronism gears, both for cutting and distellation or embossing:
