Filed: 1987-12-24
Abstract: PURPOSE:To prevent the breakdown of a preassembling ring inserting device by moving a sensor close to the surface of a signal spring wound on a winding core bar and confirming the seaming shape by the absence or presence of a contact body. CONSTITUTION:A spiral spring 3 is seamed via a winding core bar 2 on a winding base 1.
