Abstract

L'invention concerne un dispositif pour produire des blocs agglomérés de béton comportant un insert (FE) maintenu de manière interchangeable dans une machine à mouler. Selon l'invention, la liaison entre un cadre (HLL, HLR) et l'insert d'une part et entre l'insert et un support (SB) d'autre part est conçue de sorte que, lorsque l'insert est secoué, il est bloqué contre le support et détaché du cadre. Pour être déplacé verticalement, l'insert est détaché du support et couplé au cadre de manière à pouvoir coulisser en hauteur.
