PURPOSE: To make the insertion length of skewer adjustable simply and quickly, by letting skewers transported by a chain and molds formed on the outer peripheral face of a molding drum to be opposite coincidently, making the insertion length of the skewers for the molds filled with an ingredient variable and adjustable by an auxiliary cam.

CONSTITUTION: The molding drum 1 having a large number of molds for molding an ingredient on the outer peripheral face is provided and a chain to transport skewers one by one synchronistically with the drum 1 is set. The sproket wheel 5 at one side of the chain is opposite to the drum 1, and the diameter of the wheel 5 is fixed in such a way that the skewers sent by the chain and the molds are set face to face coincidently. In the device 6 for pushing the skewers, the roller 6c protruded at the rear end of the rod 6b for pushing the skewers into the ingredient under pressure, which faces each of the molds and supported rotatably with the molds and slidably, is pressed by the fixed cam 10a, and the auxiliary cam 10c is protruded to the cam 10a and adjusted depending upon the length of the molds so that the insertion length of the skewers is varied and adjusted.
