The present invention relates to a method for casting of cast parts in which molten metal is poured via a feeder, separate runners, or casting channels into a mould cavity defined by a casting mould and modeling the shape of the cast part, whereby the casting mould includes mould parts which determine the shape of the cast part to be cast. Molten metal is conveyed via at least two connections into at least two sections of the mould cavity which correspond to different planes of the part to be cast. At least one of the connections is designed as an additional channel leading through one of the mould parts and independent of the contour of the cast part to be cast. The present invention also relates to a casting mould as described above.

A roller conveyor is designed to advance successive stacks of superimposed sheets of paper or the like against an abutment. The lowermost sheets of the stacks tend to slide relative to the sheets above them, and such tendency is counteracted by constructing the roller conveyor in such a way that its major section, which is spaced apart from the abutment, advances the stacks with a first force and the next-following section thereupon advances the stacks with a greater second force. The conveyor has driven shafts which extend transversely of the direction of advancement of the stacks and are surrounded, with play, by ring-shaped or hollow cylindrical rollers which contact the undersides of lowermost sheets of the stacks.
