摘要：A linear electromagnetic actuator has it core mounted to a can body formingapparatus and its coil attached to re-draw sleeve of such apparatus. The actuatorprovides for the axial movement of the re-draw sleeve between its fully retractedposition and its fully extended position. The re-draw sleeve and the coil are coaxiallymounted to each other so that the force exerted on the re-draw sleeve is also coaxial.Once the re-draw sleeve is in its fully extended position, an electromagnet is turned onso that the re-draw sleeve exerts the requisite force on the can material preform. Theelectromagnet is mounted coaxially about the re-draw sleeve and exerts its force on amagnetic material ring mounted to the re-draw sleeve to hold the re-draw sleeve againstthe can material preform.
