Surface-treating holder having tubular structure and method using the same
View Patent ↗A surface treating holder includes a wire which is coiled at distances in such a manner that it is formed as a spring-like tubular structure having spiral-line faces at opposite ends thereof, so that works are accommodated in the tubular structure. A process for surface-treating a pluarlity of works accommodates the works in the holder, and surface treating the works in the holder while being rotated about an axis of the works.
1. A work holder in a vapor deposition apparatus for holding work pieces for vapor deposition comprising a substantially tubular body having an internal diameter of a size configured to hold said work, said body being formed of a continuous coiled wire, having spirally wound turns at opposite ends defining end closure portions to prevent removal of work therefrom, and an intermediate portion extending between said end closure portions, said intermediate portion having turns therein disposed in mutually spaced relation to define spaces for exposing said work held within the work holder to surface treating from outside the work holder.
2. The work holder according to claim 1 wherein said body is generally cylindrical.
3. The work holder according to claim 1 including means for preventing entanglement of the turns with those of another work holder in that said intermediate portion of said body includes a small diameter coiled spring wound around turns of said body.
4. The work holder according to claim 1 including means for preventing entanglement of the turns with those of another work holder in that said intermediate portion of said body, adjacent each opposite end thereof is defined by a plurality of turns of wire having substantially no clearance therebetween.
5. The work holder according to claim 1 wherein said end portion of said body is closed by a spiral winding which includes more closely wound turns in a cental region of the end portion.
6. The work holder according to claim 1 wherein said body is formed of stainless steel wire.
