A compact and efficient continuous wrapping machine capable of measuring out certain amounts of a magnetic powder automatically and wrapping them in wrapping film, the continuous wrapping machine comprising a measuring drum, a sealing drum, and a sealing device. The measuring drum includes a means for retaining measured-out amounts of the magnetic powder on its periphery and a means for cutting off the retaining force of the retaining means to transfer the measured-out amounts of the magnetic powder to the sealing drum. The sealing drum includes a means for retaining the measured-out amounts of the magnetic powder on a first continuous wrapping film fed onto its periphery. The sealing device seals the first continuous wrapping film and a second continuous wrapping film, which is fed onto the measured-out amounts of the magnetic powder on the sealing drum, together around each of the measured-out amounts of the magnetic powder.
