Flat of the continuity roller null bobbin condition continuity roller

摘要

PROBLEM TO BE SOLVED: To provide a conductive device for continuous plating of a thin sheet having a insulating part in wiring parts even in the case that the width of the thin sheet and the intervals of conductive layers for plating are different.;SOLUTION: The flat surface of a barrel part of a spoollike conducting roller is provided with a movable electrically conductive ring. For the ring, the securance of electrical conductivity is only required, and, not only a ring made of metal, but also, the one, e.g. obtained by coating the surface of a ring made of synthetic resin with an electrically conductive material can be used. Further, in the case the ring is produced by a spring material, the intervals between the rings can easily be controlled in accordance with the intervals of conducting layers for plating.;COPYRIGHT: (C)2001,JPO
