Claims
- 1. Apparatus for evaporating metal wire, comprising
- an evaporator boat,
- a drive roller having an electrically insulating circumferential coating,
- a base body to which said drive roller is journaled,
- a frame to which said base body is mounted,
- insulation means electrically isolating said base body from said frame,
- a counter roller mounted on a movably journaled lever for moving said counter roller toward said drive roller, and
- actuating means for moving said lever so that a wire can be engaged between said counter roller and said drive roller to feed said wire to said evaporator boat, said actuating means being insulated from said frame.
- 2. Apparatus as in claim 1 further comprising
- a base body to which said drive roller is journaled,
- a frame to which said base body is mounted, and
- insulation means electrically isolating said base body from said frame.
- 3. Apparatus as in claim 1 further comprising
- an evaporator boat to which said wire is fed, and
- a feed tube having a first end adjacent said drive roller and said counter roller, an opposed second end adjacent said evaporator boat, and an inner wall through which said wire is fed between said ends, said feed tube comprising a straight section extending from said first end and a gooseneck shaped section contiguous with said straight section and extending to said second end, said gooseneck shaped section deflecting said wire so that three points of contact between said wire and said inner wall are provided, one of said points being at said second end.
- 4. Apparatus as in claim 3 wherein said gooseneck shaped section comprises two bends lying in a vertical plane.
- 5. Apparatus as in claim 4 wherein said tube is aligned so that said point of contact at said second end is uppermost on said inner wall.
- 6. Apparatus for the continuous feeding of wire to an evaporator boat, comprising
- transport means for drawing wire from a source upstream and feeding said wire to an evaporator boat downstream, and
- a wire feed tube having a first end adjacent said transport means, an opposed second end adjacent an evaporator boat, and an inner wall through which said wire is fed between said ends, said feed tube comprising a straight section extending from said first end and a gooseneck shaped section contiguous with said straight section and extending to said second end, said gooseneck shaped section deflecting said wire so that three points of contact between said wire and said inner wall are provided, one of said points being at said second end.
- 7. Apparatus as in claim 6 wherein said gooseneck shaped section comprises two bends lying in a vertical plane.
- 8. Apparatus as in claim 6 wherein said tube is aligned so that said point of contact at said second end is uppermost on said inner wall.
- 9. Apparatus as in claim 6 wherein said transport means and said feed tube are so arranged that said wire enters said first end without contacting said inner wall.
- 10. Apparatus as in claim 6 wherein said gooseneck shaped section extends over half the distance between said first and said second end.
- 11. Apparatus for evaporating a plurality of wires, comprising
- a plurality of evaporator boats in a staggered array,
- a plurality of wire feeders arranged side by side to feed a respective plurality of wires to respective said evaporator boats,
- a plurality of wire feed tubes associated with respective said wire feeders and extending toward respective said evaporator boats, each said feed tube having a first end and a gooseneck shaped section contiguous with said straight section and extending to said second end, said gooseneck shaped section deflecting said wire so that three points of contact between said wire and said inner wall are provided, one of said points being at said second end.
- 12. Apparatus as in claim 11 wherein said wire feeders have a common drive roller with an electrically insulating coating, each wire feeder having a counter roller and actuating means for moving said counter roller toward said drive roller to engage a wire between said counter roller and said drive roller.
- 13. Apparatus as in claim 11 wherein said feed tubes are all substantially the same length.
