Abstract
Each oil branch duct is mounted on the machine frame so that, as the ring rail moves downwardly into an underwinding position relative to the bobbins, the oil branch duct is inserted into the oil duct carried on the ring rail. A metered flow of oil is injected into the oil duct during this time. When the ring rail moves upwardly, the oil duct moves away from the branch oil duct to interrupt the oil supply connection.
