Abstract

PURPOSE: To always wind a coil by a proper reel diameter, to stabilize the operation, and to raise the quality, by constituting so that a mandrel head can be replaced with spare parts having a necessary diameter, when changing the reel diameter of a mandrel to its expanding or reducing range or more.
CONSTITUTION: The titled device is constituted of a mandrel shaft 6 which is driven and rotated, a push rod 7, an outer board 12, and also a sleeve 8, a split segment 9, a split ring plate 10, and a sleeve connecting body 11. Said sleeve 8 has a saw-tooth wedge 8a on its outside circumferential part, is inserted and fitted into the outside of the shaft 6, and a rotation of the shaft is transmitted to this sleeve. Also, the segment 9 has a saw tooth-like wedge 9a contacting with the wedge 8a, and the diameter is expanded or reduced in accordance with a movement of the sleeve 8. In this way, a mandrel head consisting of said sleeve 8 and segment 9 is unified with the connecting body 11, is replaced with spare parts, and the reel diameter of the mandrel is greatly changed.
