    摘要: A method of and a system for detecting pinholes in hollow fibers by passing a liquid filled fiber into a zone of pressurized gas wherein the pressure of a gas is higher than that of a liquid inside the hollow fiber so that bubbles may be injected through pinholes contained in said hollow fiber and then passing the fiber through a bubble detector. The system can be operated continuously with the pinhole detector being between a device for continuously feeding the hollow fiber and a device for winding up said hollow fiber.
