Grooved pins 15, 16 and threaded bushes 17, 18 are embedded in the filler to implement the anchoring of the sheets and their subsequent assembly in a magazine. A mold assembly is built up by clamping together a plurality of curved mold plates 20, and disposing a pair of magnetically fixed sheets 11, 12 between adjacent plates, whereafter the filler 14 is introduced under pressure.
