2117999 9320705 PCTABS00027 Partially formed products (2) are placed in molds (8) and a fluid such as air or an edible filler is injected into the partially formed products (2), e.g. by needles 17 ¢Fig. 6!, so as to cause expansion and thereby produce final products (2) having the shape of the molds (8). Each mold (8) may comprise an upper mold part (14) and a lower mold part (11). The lower mold parts (11) may be mounted on a chain conveyor (9, 9b, 9c) ¢Fig. 1! or a rotating cylinder (28) ¢Fig. 12! so that the partially formed products (2) are moved towards and the final products (2) are moved away from a reciprocating assembly (12, 13) which carries the upper mold parts (14). Preferably, the final products (2) are retained in the upper mold parts (14) and then ejected by a blast of air. The invention enables complicated shapes to be formed at high production rates whilst using an economical amount of chocolate or the like.
