  • Patent number: 4852218
    Abstract: A process and apparatus for automatically changing drums which are to receive wicks which are delivered by textile machines. The apparatus includes a translationally movable table. A means for gripping and pulling a wick in a second opposite direction and a means for gripping and severing a pulled wick are provided. At least a portion of both of these means are carried on the table. Positioned thusly, when the table moves in a first direction, that is opposite to the second direction. The table passes under a feeding head that distributes the wick, such that the wick is received on the table and on both of these means. In second position, the one means grips the wick and pulls it in the second opposite direction. Simultaneously, the other means grips and severs the pulled wick. The one means then advances and guides the wick into a drum being filled by the feeding head. Means is also provided for moving the drums in the first direction concomitantly with the movement of the table.
