• the compact disk blanks or the like. are manufactured on injection molding machines. Below are also supposed to be. Injection molding machines and automatic presses can be understood.
• the blanks are removed from the mold of the injection molding machine by means of a handling device and are usually transferred to a transport magazine. In these transport agazines the internal transport takes place to a metallization device in which a metal layer is applied on one side. The input to the metallization device is made using a handling device.
• Another or the same handling device removes the blanks processed in this way and places them again in a transport magazine in which the further transport to a painting device takes place. After the painting process, the compact disks are stacked in transport magazines.
• a handling and conveying device of the type mentioned at the beginning is used.
• An input handling device takes over the blanks at a delivery device of the injection molding machine and places the blanks on a conveying device that feeds the blanks to the metallization device.
• one or more injection molding machines work together with a metallization device. Different information is usually stored on the compact disk blanks coming from the individual injection molding machines. Nevertheless, these blanks are in a disordered order
• the object of the invention is therefore to provide a handling and conveying device of the type mentioned at the outset, which makes it possible to chain injection molding machines, metallization devices and painting devices with one another in such a way that, on the one hand, optimum use is made with the smallest possible space requirement the manufacturing capacities of the individual processing machines is made possible, but on the other hand there is no need to read the CD disks after production
• painting facilities should also include facilities for applying another protective layer or the like. be understood.
• Injection molding machines come, there is an orderly delivery to the metallization device and an orderly Removal, so that the different blanks are fed to the two separate painting lines of the painting device without the need for a sorting process. From there, the CD disks can be placed in a magazine without sorting; Confusion of information content is excluded.

• the input handling device 6 or 7 places the blanks 3 on an adjacent rotary table conveyor 8 or 9 in a first table pivot position 10 or 11.
• the two rotary table conveyors 8, 9 set up adjacent to one another are cyclically advanced in the direction of the arrows 12, so that the blanks reach a second table pivot position 13 or 14.
