Abstract: A powder spraying head for spraying a powder on a can body to be coated comprises a work chamber inside the powder spraying head, a powder tube for providing the powder, a charging electrode for charging the powder with an electrostatic charge and a guiding electrode for deflecting the powder present inside the work chamber substantially in the direction of the work opening. The charging electrode is arranged in the area of the powder outlet and is formed with a tip in the direction of the powder streaming into the work chamber. Additionally or alternatively, the guiding electrode is plate-shaped and a flat side of the guiding electrode is oriented towards the work chamber.

Abstract: A device for interruption-free coating of can bodies with a coating liquid comprises an inlet container for providing the coating liquid to be applied, a pressurized air source for supplying pressurized air, an application nozzle for spraying the coating liquid with an application pressure onto the container body. An intermediary container is provided, which is connected on the inlet side to the inlet container by means of the inlet pipe and which is connected on the outlet side to the application nozzle by means of an outlet pipe.

Abstract: In case of manufacturing tear-off lids (28) out of lid rings (20?) with a tear-off foil (25) sealed on them and with a tear-off tab (29) the tear-off tab is fixed in a folded back position onto the tear-off foil of the lid by an adhesive patch (30). For this, the adhesive patch is applied onto the foil section in such a way that individual adhesive patches are separated out of an adhesive tape with a carrier tape and an adhesive material arranged thereon by a separating means. Such an adhesive patch is arranged on the foil section of each lid in a position where the folded back tear-off tab comes to lie. By this, a fixing of the tear-off tab can be reached in an economical and secure manner.
