Abstract: In order to provide an aerosol device (100) that makes it possible to provide an aerosol having an optimised composition, in particular optimised droplet size distribution, it is proposed that the aerosol device (100) should include the following: an aerosol casing (102); one or more aerosol nozzles (104) for generating an aerosol stream from a carrier gas and a liquid, wherein the one or more aerosol nozzles (104) are directed into an interior (106) of the aerosol casing (102) and/or are arranged in the aerosol casing (102); one or more carrier duct connection points (156) for connecting one or more carrier ducts (158), by means of which the aerosol is guidable away from the interior (106) of the aerosol casing (102).

Abstract: A microlubrication system for a machining unit with a rotating spindle, the system having a rotary feedthrough via which compressed air and lubricant can be fed to the rotating spindle to combine them in a mixing chamber close to a tool, and a metering valve by means of which the amount of the fed lubricant can be dosed. In order to improve the monitoring and the control of the system, the rotary feedthrough and/or the metering valve are designed as smart components.

Abstract: A spindle which can be used by using the two-channel minimal quantity lubrication. The feeding of the lubricating oil is done by way of a central oil tube which is rotationally fixedly joined to a fixed base piece and which is radially supported on the revolving spindle in the radial direction by way of at least one pivot bearing.

Abstract: A method for applying powder to a printed sheet includes ejecting air flows from a nozzle bar. The air flows are set in such a way that the air flows which are ejected per meter length of the nozzle bar produce a resultant force acting on the printed sheet of from 0.5 newtons to 16 newtons. A printing press for carrying out the method is also provided.

Abstract: The invention relates to a device for powdering printed sheets, especially printed sheets made out of paper, whereby a powder coating device is arranged inside a sheet feeding device and an electrostatic charging device that is disposed outside the sheet feeding device is assigned to the sheet.

Abstract: A method and device for powdering the printed sheets of paper. Powder is periodically introduced into the airflow by a dosing element.

Abstract: The invention relates to a method and a device for powdering printed paper sheets. According to the invention, the performance of the air-pressure generator which generates the air stream for the powder-air mixture can be adjusted in line with the machine speed or the speed of transportation of the paper sheets.

Abstract: The present invention relates to a device and method for dusting smooth or sheet-like products, comprising at least one duster for spraying an air/powder mixture on said products. In order to ensure efficient dusting with no dirt accumulation in the printer or the surrounding area, it is suggested that part of the powder particles be magnetized and means be provided for creating a magnetic field in the powder deposit area so that said powder particles are subjected to a force drawing them towards the product.

Abstract: The invention concerns a method and a device for applying powder on sections of printing sheets (2). The invention includes a powder airflow (8) enclosed in a protective airflow (13) such that the powder airflow is steady and protected against the action of possible disturbances until it reaches the sections of printing sheets (2).

Abstract: A device for powder, wherein a powder container, an intermediate container and a dosing element are successively arranged in a versicle container. The powder is conveyed from the powder container into the intermediate container and, subsequently, into the dosing element. This results in a regular discharge.

Abstract: The present invention relates to a device for generating a powder-air mixture, having a powder delivery device, a conveying air feed pipe for the conveying air, and a device for forming an enveloping conveying air jet. The powder delivery device terminates in the conveying air feed pipe and therefore in the enveloping air jet.

Abstract: A powder device comprises a powder container which is formed as an exchangeable container mounted on a container receptacle via a quick-connect means. The inside of the powder container has a dome which extends from the output flow opening into the inside of the powder container. This loosens up the powder and prevents it from adhering to surfaces.

Abstract: The present invention relates to a device for metering a powder, having a device for the delivery of powder, a axially symmetrical metering element arranged underneath the delivery device, and a drive for the axially symmetrical metering element, wherein the axially metering symmetrical element has a surface profile extending in the circumferential direction, and is adapted in its configuration so that the powder is not compressed during movement about the axially symmetrical metering element.

Abstract: In a two-bed flat knitting machine separate sinker control devices are provided for controlling sinkers arranged between needles and have a device body laterally releasably mountable on a machine carriage. They extend only over an operating region of a cam system and their control parts are formed so that they are displaced during a carriage stroke return automatically to an operative position or a rest position.
