Multi-format dies with interchangeable matrix (mirrir or re-entrant) This system enables the production of the base format as well as its submultiples with one die, be it a mirror or a re-entrant die. (Ex. 2 outlets 60×60 – 4 outlets 30×60 – 8 outles 30×30), (Ex. 2 outlets 50×50, 4 outlets 25×50, 8 outlets 25×25, 8 outlets 12,5×50). Significantly reduces changeover times (estimated time 3/4 hours), the matrix is self-centering and easy to remove and replace. Moreover with this system can turn the matrix occurred to wear and use the opposite side to deliver twice duration.
