  • Selective plating apparatus
    Patent number: 4553501
    Abstract: An apparatus for selectively plating on an elongated metal strip, at intervals of a predetermined length in the lengthwise direction, while the strip is being fed in the lengthwise direction. The apparatus includes: strip feeder which discharges the strip from a reel in a direction in which the strip is fed and a sensor for detecting the amount of slack in the strip. A pre-treating station treats the strip, before being plated, while it is continuously fed. A plating station intermittently feeds the strip and selectively plates it, while the strip is stopped during its intermittent movement. An after-treating station treats the strip by again continuously feeding the strip and a strip take-up section winds the strip onto a reel after it has been treated. Tension mechanisms are disposed between the continuous feeding station and the intermittent feeding station to impart a predetermined tensile force to the strip.
