cylindrical funnel moulding

[ziotoy]

Can anyone help me?
I would like to know how a step mold works for the production of a glass as from attached images.
the problem is this: the cylindrical assembly of the sheet in the first step is greater than that of the next steps.
when the sheet rolls one step, the primer drops and crushes the sheet before the punch of the second forming arrives. creating a disaster. I think I understand what I mean.
How does it work?
Thank you.
Say hi.

the primer includes only insulation and first funnel.
in the next steps you need to insert a fixed detachment to the matrice plate.

You can explain yourself better, I don't understand!
Maybe if you put an example, even a sketch would be better.
Thank you.

I attach an example of a possible solution

Good day to all
I have a particular almost identical to that proposed initially by my colleague Uncletoyfep04 material - thickness 0.6mmhaving never made a step mold with these features, I developed the ribbon scheme automatically with visicad and, for safety, I looked for various board tables on the web that confirm more or less this sequence
but my doubt is the same as the colleague and I have not understood the solution proposed by the
the 3rd step is a normal surface tape funnel, with sup primer and lower extractor
from the 4th step onwards, the upper premilamiera, which descends to bring the tape to the matrice plane, "wastes" all the previous steps (visible in white drawn on the scheme) of ø larger in the smaller matrices, until the upper punzones arrive
I think I missed something on the street. if in the next steps there is not the primer and there is only one detachs tape, as I think I have understood from ernesto, the sheet would be arranged "to bridge" between the first steps and the last of detachment
other doubt... the upper punches perhaps should be fixed to the primer (working with the load tires) instead of coming in a second moment with the upper fixed?

from the 4th step you should not put the primer anymore.
Surely the sheet has a bridge on the contrary is a "uphill line".
the punches are fixed, that is, they do not flow, at the top of the mold.
