The automatic drawing-in system, installed onto the vehicle individually driven wheels that runs around the factory floor, is developed in order to improve drawing-in operation. Results obtained are as follows : (1) The auto-doffing system is composed of the automatic yarn draw-in apparatus, which can draw Spandex in both upper and lower hollow spindles simultaneously by air flow, and a vehicle which runs in contact with the covering machine. (2) The developed device can draw-in 30D, 70D, 140D Spandex that are widely used and too fine to be easily drawn-in even by manual operation. Success rate more than 90% of Spandex drawing-in can be obtained by supplying the air pressure for the ejector at 0.5 MPa and for the injector at 0.4 MPa. It confirms that the developed device has practical utility}, pages = {76--80}, title = {カバリングマシンの自動糸交換装置の開発: (第3報) 自走台車に設置した自動糸芯通し装置}, volume = {51}, year = {1998} }
