ABSTRACT:
The invention relates to an arrangement for pressing flexible discs by compression under heat, comprising heating plates, each carrying a plate of flexible closed-cell foam similar in diameter to the engraved matrices. The flexible disc to be pressed is placed between an engraved matrix and a counter plate or a second engraved matrix, the assembly being placed between the plates of closed-cell foam in such a way that, during compression, these cellular foam plates act as a pneumatic compensator and enable the pressure to be uniformly distributed over the surface to be engraved.
