Abstract
A length of conductive wire is supported between a first reel and a second reel. The first reel is driven to move the wire through the device in a stepped fashion. Each time the wire stops a reciprocating plunger brings a material to be evaporated into contact with the wire. An electric current is passed through the length of wire in the area where the material contacts the wire. The wire is heated by the electric current to melt the material onto the wire to form a bead of material thereon. The wire is advanced to repeat the bead forming process. The wire with the beads formed thereon is wound onto the first reel for later use in an evaporator process. An infrared sensor monitors the heating process to determine if the material is melted at the desired temperature. A sensor is also provided to stop the device if the wire breaks. The advancing of the wire, the operation and refilling of the plunger and the heating of the wire are all performed automatically.
