Abstract

La présente invention concerne un dispositif de charge se trouvant dans une machine à mouler conçue pour produire des briques moulées en béton. Ce dispositif est de construction particulièrement simple et stable. Un mode de réalisation préféré comprend un support de poinçon creux, formé de tôles pliées, et un poinçon de pression, maintenu dans ce support de manière stable. Un cadre de raccord séparé, à fixer sur la surface supérieure du support de poinçon, permet de l'adapter facilement à des systèmes de fixation d'une machine à mouler.
