In a take-up ring for a circular die for extrusion molding into films and pipes, the driving device is provided at both ends in a diameter direction of the annular shaft, and the roll member is installed at both ends in a diameter direction perpendicular to the diameter direction. The taking-off ring for a circular die is provided with a device for rotatably supporting the rigid annular shaft.
