Closure lining and color detector

A method for identifying container closures having a deficient color status from container closures having a sufficient color status, said method comprising the steps of:

• (a) forming a compound on an inside panel surface on substantially each one of said closures in a compound station;
• (b) conveying said closures from said compound station to a color sensor on a conveyor;
• (c) sensing a color of substantially each one of the closures by said color sensor;
• (d) identifying the color as either a sufficient color or a deficient color, the deficient color status corresponding to a predetermined color of said panel surface substantially lacking the compound at a predetermined portion of the panel;
• and
• (e) automatically separating the closures having the deficient color status from the closures having the sufficient color status.

A system for detecting a predetermined color of decorated metal disks that are capable of being formed into container closures, said system comprising:

• a conveyor for moving said plural decorated metal disks longitudinally therealong, said decorated metal disks having a colored side that is oriented upwardly on said conveyor;
• a color sensor that senses said the colored side of substantially each one of said decorated metal disks for a predetermined color, said color sensor being capable of identifying a sufficient color status that corresponds to a predetermined color on at least a portion of said decorated metal disk and a deficient color status that corresponds to a color that is not said predetermined color;
• and
• a separator capable of removing from said conveyor a decorated metal disk having a deficient color status;
• whereby said system automatically identifies and removes said decorated metal closures that have said deficient color from the conveyor.

A method for identifying a predetermined color of decorated metal disks that are capable of being formed into container closures, said method comprising the steps of:

• (a) conveying the decorated metal disks to a color sensor on a conveyor;
• (b) sensing a color of each one of the decorated metal disks by said color sensor;
• (c) identifying the color as either a sufficient color or a deficient color, the sufficient corresponding to a predetermined color, the deficient color corresponding to another color that is not the predetermined color;
• and
• (d) automatically separating the decorated metal disks having the deficient color status from the closures having the sufficient color status.
