ABSTRACT:
A workpiece-treating system and a related method are disclosed. Workpeices, such as for example coils of collated nails, are conveyed successively into a first container for treatment within a first bath, such as, for example a nail-cleaning bath, out from the first container, into a second container for treatment within a second bath, such as, for example nail-coating bath, and out from the second bath. A carrousel having three workpiece-holding platforms is used to convey the workpieces as mentioned. Means are provided for mounting the carrousel so as to enable the platforms to be conjointly and selectively raised or lowered and to enable the carrousel to be selectively indexed about a vertical axis through a cycle of three working positions when the platforms are raised. Means are provided for rotating each platform about a vertical axis for a selected period of time. The respective containers are positioned where a selected platform is lowerable into the first container and a different platform is lowerable into the second container in each working position of the carrousel.
