Abstract (en)
[origin: EP2756896A2] The device (10) has two mold halves (12,14) mutually arranged opposite to each other. The pointing surfaces (16) of mold halves are parallel to each other and to flow direction and provided with crosswise running projections (18) and recesses (20). A washboard, labyrinth or meander-shaped gap (22) is partially formed between inlet (24) and outlet (26) of mold halves to flow displaced air and excess molten-liquid material from mold. The mold halves are releasably arranged next to each other in longitudinal direction and provided with connected segments (12a-12c,14a-14c).
