A cast metal feeder has a feeder head (1) having a hollow space with at least one hole (8) open to the environment, and a tube-shaped body (2) which can pass thru the hole with provision for displacement in it. The tube-shaped body has an element (9) which passes round the outer periphery of the tube-shaped body and prevents tube from falling out. An independent claim is included for the production of the above feeder. |
