A method and system for feeding a lubricating or releasing agent from a dosing station to one or more pressing tools arranged in a pressing chamber of a tablet press. The tablet press is configured with a feed pipe for feeding the lubricating or release agent from the dosing station to the one or more pressing tools of a pressing chamber of the tablet press and the feed pipe is configured with a shut-off valve disposed in-line with the feed pip for controlling the flow of the lubricating or release agent to the pressing chamber. The method comprises the steps of: producing a negative pressure with respect to the surroundings of the pressing chamber of the tablet press, measuring a pressure in one of the feed pipe and the pressing chamber, and issuing a signal indicative of the measured pressure and issuing an enable signal to open a valve in response to the pressure signal.

The present disclosure teaches systems and methods for coating and cooking goods. One system for coating of goods can comprise a source of powder for coating the goods, a source of gas to create a gas stream to carry the powder and the goods in a combined stream through a tunnel or chamber comprising air bearings to keep the goods and the powder from contacting the inner surface of the tunnel or chamber, and a system for recirculating unused powder for reuse. One method for coating goods can comprise combining additive powder with at least one gas stream in a powder circulation chamber and forming a powder gas stream, forming an air bearing on an inner surface of the powder distribution tunnel wherein the powder distribution tunnel comprises an inner tube and outer tube can be separated by a plenum, wherein the air bearing is formed by directing a gas stream through the at least one compressed air inlet causing the tunnel gas stream to form a circular vortex ring having a centrifugal force equal to a pressure gradient outward and releasing goods into the powder distribution tunnel to coat the goods.

A method for recycling powdered paint waste is provided in which, the powdered paint waste is being treated with the aid of a reactant in such a way that its adhesion to surfaces and especially to metal surfaces is reduced or eliminated. The treatment of the powdered paint waste allows the powdered paint waste to be additionally processed under the influence of heat and to use it as a starting material in various recycling processes or in other processes.

The invention relates to a coating device and to a method for metal-coating of workpieces, comprising a housing, which surrounds a working space, a retaining apparatus for retaining at least one workpiece in the working space, at least one deposition apparatus comprising a deposition nozzle for applying a metal powder to a workpiece surface to be coated, and a laser for locally melting the metal powder on the workpiece surface to form a coating, at least one movement apparatus, by means of which the at least one deposition apparatus can be moved relative to the workpiece surface during the coating, at least one air supply and at least one air discharge. According to the invention, it is provided that the air supply is arranged in an upper region of the working space above the workpiece and the air discharge is arranged in a lower region of the working space below the workpiece. In addition, a additional suction apparatus is provided with at least one suction opening, which is arranged close to the workpiece.

The invention relates to a method and to a system for metal-coating at least one surface of a workpiece, in which before coating, a surface structure with peaks and troughs in the surface to be coated is detected by means of a measuring apparatus, the coating is carried out by means of at least one deposition apparatus, which is moved relative to the surface and applies coating material in the process, and the deposition apparatus is controlled by a control apparatus on the basis of the detected surface structure, wherein more material is applied in the region of troughs and less material is applied in the region of peaks.

A transfer and coating apparatus transfers a component from a conveyor to a coating station for application of a coating. The transfer apparatus includes a mast that can move about orthogonal axes in a horizontal plane and a mast having a carriage that can move vertically. The carriage includes a hook that swings about a horizontal axis relative to the mast for movement of the component in the horizontal direction. A sway bar extends between the hook and component to inhibit movement about a horizontal axis. The component is delivered to an upper compartment of a coating apparatus where it can be lowered in to a lower compartment containing coating material. Excess coating material is removed by an array of nozzles in the upper compartment as the component is raised from the coating material.

A combined spray and vacuum nozzle includes a nozzle housing containing a powder supply passage and a vacuum withdrawal passage, where the powder supply passage and the vacuum withdrawal passage are arranged in a side-by-side relationship. The nozzle housing has a proximal end portion and a distal end portion. The distal end portion features a spray port in communication with the powder supply passage and a vacuum port in communication with the vacuum withdrawal passage. The spray port is positioned adjacent to the vacuum port. The proximal end portion of the nozzle housing adapted to communicate with a source of aspirated powder and a vacuum source so that the powder supply passage communicates with the source of aspirated powder and the vacuum withdrawal passage communicates with the vacuum source.
