Apparatus for forming layers of fusible metal on articles

摘要: In fabricating sealed contacts, often their axially extending leads are solder coated to protect them from contamination and enhance solderability into circuits. An apparatus for coating the leads, which minimizes bending, includes a conveying that moves contacts through various stages of form layers on leads. These layers, carefully controlled, no greater than certain maximum thickness, thinner ends side surfaces thereof. To coat individually mounted in plurality holders, each is fixed an individual bead endless chain apparatus. As advanced passageway tube having curvilinear rectilinear slots formed outer surface thereof, holders these oriented longitudinal positions along angular about appropriately orient first stage, loaded bin moved predetermined orientation second stage where mixture powdered flux applied lead by wheels resilient peripheral surfaces. The simultaneous contact with mixture. Next same heating baffle arrangement substantially confine hot gases vicinity melt then longitudinally rotatably due camming action holders. This changes immerses clenching bath remove any residual next out cleaning rinsing bath. Finally, drying chamber remnants stripped bin.
