ABSTRACT:
A lower film is carried continuously along a passage having a substantially horizontal first passage part and a downwardly curved second passage part. While the lower film is carried along the first passage part, a plurality of recesses are formed on the lower film by a molding device which is moved in synchronization with the advancement of the lower film. An upper film is supplied continuously in such a manner that both upper and lower films approach together in the shape of "V" in section at the second passage part and they are sealed together as they move down further along the second passage part. While the films are partially sealed at the second passage part, powdery or particle-size material is fed into the recesses in the lower film.
