PROBLEM TO BE SOLVED: To maintain the proper warming temperature by the rotation of screws. SOLUTION: Screws 30 and 32 for transferring and warming a rough fabric while providing the fabric with shear force are rotated in the reverse directions each other by motors 50 and 52 respectively, The number of rotations of the screw 32 driven by the motor 52 is. varied by a controller 54 based on the temperature sensed by a temperature sensor 56 and the temperature preset as the warming temperature while keeping the number of rotations of the screw 30 driven by the motor 50. When the temperature sensed by the temperature sensor is too high, the number of rotations of the screw 32 is reduced, while when the temperature sensor is too low, the number of rotations of the screw 32 is increased to maintain the temperature sensed by the temperature sensor constant by the arrangement. |
