摘要： A machine for making and painting test tubes by painting open-ended tubes and then fusing and severing them to form individual test tubes.Substitutable paint applicators varying in width, adjustable in location relative to the open-ended tubes, apply paint thereto by means of wiping action caused by rotating said open-ended tubes while in engagement with said paint applicators. The open-ended tubes are then individually fused and severed intermediate their open ends to form, from each open-ended tube, two separate test tubes having painted bands of the desired width and at the desired location, including painted bands which are contiguous with the open ends of the test tubes.
