PURPOSE:To make it possible to improve the operatability and freely alter a pasting position by fitting a cylindrical shell body around the space between a wound paper supporting part and the pivotting part of a spider arm and providing a dog on the peripheral surface of said shell body. CONSTITUTION:A shell body 20 is formed by magnetic substance, and a non- magnetic substance dog 21 is provided in one place on the peripheral surface of the shell body 20. A proximity switch 13 for detecting the access of the dog 21 while allowing said switch to approach the rotary orbit of the dog 21 from the outside is provided on a spider arm 2. The shell body 20 can properly select its phase by turning the shell body in the opposite direction to that of a winding cone 14, so that it is possible to adapt the desired pasting position on the outer periphery of wound paper 7 to a pasting pointer by turning the shell 20 without turning a heavy wound paper 7. |
