Abstract: An arrangement including a welding arm (2) for a resistance seam welding machine and a roller head (1) fastened thereon, which has a stator (3) and an electrode roller (4) which is supported as a rotor on the stator (3) in a rotatable way, wherein the stator (3) protrudes over the electrode roller (4) with fastening extensions (5) on both sides of the electrode roller (4). The welding arm (2) has a reception opening (6) for the roller head (1), which is formed between two limiting walls (7) facing each other, which themselves have fastening reception openings (8) for the fastening extensions (5). The roller head (1) is arranged inside the reception opening (6) in such a way that the electrode roller (4) protrudes outside the reception opening (6) with a part of its circumferential boundary and the fastening extensions (5) are arranged inside the fastening reception openings (8).

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: A tear-off lid with a curled edge of the removal opening is formed such that before the edge is curled, a plastics layer provided as a band of low thickness and preferably only 0.1 mm thickness is applied to the collar of the lid ring. In this way, a good seal of the cut edge of the tear-off lid is produced economically and with the possibility for production at a high rate.

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 magnetic lifting device for bodies (Z) comprises an input transport device (10) for transporting lying bodies (4), a transport device (12) for transporting lifted bodies (9) hanging at the transport device (12) and arranged above the input transport device (10) and a control device (13). A first magnet arrangement (1) which is activated and deactivated by the control device (13) is arranged below the input transport device (10) in such a way that a body (4) lying on the input transport device (10) is magnetically held in a releasable way on the input transport device (10). A second magnet arrangement (2) is arranged above an area of the input transport device (10), in which the bodies are transported, and is formed in such a way that a body lying on the input transport device (10) is lifted by the magnetic field of the second magnet arrangement (10) when the magnetic field of the first magnet arrangement (1) is deactivated.
