The vehicle type auto-doffing system for the covering machine is proposed in order to give a concrete form to draw core yarn into its hollow spindles. Results obtained are as follows : <BR> (1) From the viewpoint of doffing operations, the features of the covering machine are as follows ; the dimensions between its bottom position of the core yarn package and its top position of the take up package is too large for operators to handle packages easily, and a large number of operations to exchange yarn packages are needed for a series of doffing operation.<BR>Therefore, its automation is required strongly. The subjects are specified and the plans to settle them are clarified.<BR> (2) We develop the vehicle type auto-doffing system equipped with two drive wheels and two casters, controlled by individually driven wheel method that the right and left wheels revolve individually. It is able to exchange the core yarn packages continuously moving in contact with the straight frame of covering machine.
