  • Publication number: 20110143520
    Abstract: A system for treating distinct batches of workpieces to serial procedures comprises first and second multi-site structures. In each multi-site structure the sites are rotatable for alignment in turn with loading and unloading stations together constituting treatment or process stations. Workpieces of a batch are loaded onto all of the treatment sites and then simultaneously and identically treated by operation of treatment stations with which the process sites are aligned. After treatment in the first structure, workpieces of a batch are transferred from the unloading stations of the first structure to the loading stations of the second structure for further processing.

  • Publication number: 20110143521
    Abstract: A system for simultaneously treating multiple workpieces is configured with treatment sites, configured to hold respective workpieces, fixed on a rotatable base. Treatment stations are equipped with respective active components operable simultaneously to treat respective workpieces identically on respective aligned treatment sites. For loading and unloading the treatment sites are rotated through distinct loading and unloading stations of the treatment stations which allow loading of a second batch while a first batch is being unloaded.
