forming flower roll.

[apolly]

Из описания формовочного стана:
A forming flower complying with a tube size and sort of steel will be selected, and an appropriate roll positioning will be calculated and indicated.

В интернете нашла объяснение: Design of the rolls starts with a flower pattern, which is the sequence of profile cross-sections, one for each stand of rolls.

Но как это по-русски адекватно сказать? шаблон, схема?
Спасибо!
