    摘要: An apparatus is provided for transferring a cylindrical work piece from a first work station to a second work station is provided. The apparatus comprises a transfer element extending substantially in one main plane, and moveable in said plane. The transfer element is provided with a plurality of openings therethrough in which bushes for receiving and transferring work pieces are mounted to be moveable with the transfer element. A device moves each bush into approximate axial alignment with the first work station for receiving a work piece and then in approximate axial alignment with the second work station for discharging a work piece. The bushes are floatingly mounted within the openings to compensate for errors in axial alignment.

    摘要: A method is provided for manufacturing a dimensionally stable compressed article such as an absorbent catamenial tampon comprising compressed cellulosic fibers. The method comprises the steps of first radially compressing a cylindrical blank to form a radially compressed blank having a length in excess of the desired finished length; then axially compressing the blank in a heated chamber to a length less than the desired finished length; then allowing the blank to expand to the desired finished length; and then maintaining the blank at this length while still in the heated chamber until the blank obtains the desired stability.
