Japanese Patent JP2016121003
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a winding core that enables checking of vertical internal stress of a processed base material wound by continuously processing a long base material, even when it is wound in a small size, and an internal stress measurement system.SOLUTION: A winding core 1 is installed in a winding device for winding a long base material. In the winding core 1, a pressure sensor 2 for detecting vertical stress for winding, and a radio transmitter 10 for transmitting a pressure value measured by the pressure sensor 2 are embedded.SELECTED DRAWING: Figure 1
