An apparatus (10) for feeding electrode capsules (12) has two stations (14a, 14b) for withdrawal of electrode capsules (12). The withdrawal stations (14a, 14b) have a mirror-image arrangement with respect to a given intermediate plane (P) and are situated in a peripheral zone of the apparatus (10). Two guide ducts (16a, 16b) house two respective rows of electrode capsules (12). Two prechambers are provided, each one being arranged between the associated withdrawal station (14a, 14b) and an outlet end of the associated guide duct (16a, 16b). A retractable stop pin is mounted between each prechamber and the associated withdrawal station (14a, 14b), said pin, when extracted, blocking an electrode capsule (12) inside the withdrawal station. In order to transfer an electrode capsule (12) from the prechamber to the associated withdrawal station (14a, 14b), the apparatus (10) is provided with two positioning devices (32a, 32b) which can be selectively operated. Two pneumatic connections (30a, 30b) are each connected to one of the guide ducts (16a, 16b) so to introduce selectively and independently pressurised-air flows into either one of the guide ducts (16a, 16b). The pressurised air acts directly on the electrode capsules (12) contained in the chosen guide duct (16a, 16b) and causes them to advance towards the respective withdrawal station (14a, 14b). |
