- changes in the process flow can be carried out without any problems, such as switching from a single to a multiple coating (1 to 3-fold coating or more), since this only requires changes in the cycle with regard to the assignment of the workpieces to the individual processing stations .
- These changes can be made programmatically.
- intermediate treatments between individual processing steps eg intermediate drying between multiple coatings
- the workpieces can be carried out on a circular path in workpiece holding stations with uniform spacing of the workpiece holding stations, e.g. at an approx. 6 ° angle.
- the method according to the invention allows the machining process itself to be significantly simplified and changed by using a contact roll coating for a preferred method for the internal and / or external coating of hollow cylindrical workpieces instead of relatively expensive spray coatings that are satisfactory in terms of material consumption and environmental protection can.
- the aforementioned object is achieved according to the invention with regard to the device for processing, in particular coating workpieces in at least one processing station in a device of the type mentioned at the outset, in that the workpiece receiving stations are arranged on a station carrier and at least one treatment station is provided, to which the station carrier including the Workpiece receiving stations executes a relative movement.
- Such a device enables the arrangement of one or more, for example external, processing stations, into which the workpiece receiving stations loaded with workpieces for carrying out machining, in particular internal and / or external coating, for example hollow cylindrical workpieces, are clocked or also guided continuously according to a program flow chart, wherein preferably three-axis movable coating rollers are arranged in the processing stations for an internal coating (optionally after primer pretreatment) and / or an external coating of the workpieces, which are preferably rotatably received in the workpiece receiving stations.

It goes without saying ne further that the peripheral speeds of the coating tool and the workpiece can be different.
- the workpiece can also be held stationary and the coating tool can be moved on a circular path for internal processing (here in particular internal coating).
- such a workpiece pick-up station is not limited to use as a workpiece carrier for coating processes, but other machining operations can also be carried out in corresponding processing stations to which the workpiece pick-up station is assigned, e.g. Surface finishing, ink or laser beam printing, impregnation or conditioning of workpieces, abrasive or depositing surface removal or application, etc. respectively.
- a particularly advantageous embodiment of the device for processing, in particular for coating workpieces is provided in that the workpiece receiving stations are formed in a ring carrier.

It also becomes possible to effectively seal the inside of the drying station from the outside. In this way, a further increase in machining efficiency is advantageously achieved.
- a particularly advantageous embodiment of the device is provided in that the workpiece receiving stations are formed on the ring carrier in a uniform circumferential division.

- Such elements are e.g. for engine mounting or for storing vibrating parts.
- To prepare an elastomeric connection between such an inner cylinder and an outer cylinder it is necessary to coat the outer surface of the inner cylinder and the inner surface of the outer cylinder with an adhesion promoter in order to subsequently introduce an elastomeric connecting compound which, with intimate adherence to both cylinders, the space between The inner and outer cylinders must be completely and permanently filled and must be able to withstand considerable loads.
- this generally requires an effective coating process with an adhesive adhesion promoter, possibly also several such coating processes with intermediate and final drying of the individual adhesive (adhesion promoter) coatings.

- the workpiece can be guided out of the workpiece receiving station 1 either after repeated rotation with the rotary table 60 to dry the adhesive coating from the coating station XII to the unloading station E, or a second active coating in the coating station XI can follow this drying process, whereby the workpiece 61 is then released after passing through the furnace 62 again when the workpiece receiving station 1 is in the unloading station E.
