A method for forming a film of particles on a carrier liquid present in a receptacle, for depositing this film onto a substrate, the method including: making a film blank between a barrier and a head including a tilted ramp, the blank being obtained by dispensing particles via the tilted ramp and carried out until the particles floating on the carrier liquid occupy a space between the barrier and an upstream front of particles located on the tilted ramp; and elongating the film by continuing dispensing the particles, and moving the head to move away from the barrier, the film elongation being performed to hold a front of particles on the ramp.

A powder conveyor has a pneumatically actuated dense phase powder pump and a pressure controller. The dense phase powder pump comprises at least one conveyor chamber having a powder inlet valve and a powder outlet valve. The pressure controller can be used to adjust and maintain a set pressure on the at least one conveyor chamber of the dense phase powder pump that is or can be previously defined and/or to adjust and maintain an actuation pressure on the powder inlet valve or the powder outlet valve that is or can be previously defined. The powder conveyor further comprises a gas flow detection device for detecting or determining a quantity of gas that is fed or removed per time unit when the set pressure is adjusted and maintained on the at least one conveyor chamber or a quantity of gas that is fed to the powder inlet valve or the powder outlet valve per time unit when the actuation pressure is adjusted and maintained. An evaluation device compares at least one detected or determined gas flow value with a corresponding set value and automatically generates an error and/or alarm signal when a deviation is detected.

A reactor for coating particles includes a stationary vacuum chamber to hold a bed of particles to be coated, a chemical delivery system, and a paddle assembly. The paddle assembly includes a rotatable drive shaft and a first plurality of paddles and a second plurality of paddles that extend radially from the drive shaft. The spacing, cross-sections, and oblique angles of the paddles are such that orbiting of the paddles causes the first plurality of paddles and the second plurality of paddles to displace substantially equal volumes in opposite directions in the lower portion of the stationary vacuum chamber.

A method for distributing granules may include transporting a hopper along a roof while releasing granules through a valve of the hopper, thereby depositing a line of granules on the roof. Another method for distributing granules may include adjusting a valve of a container mounted on a cart, depositing a predetermined width of the granules though the valve onto the roof while driving the cart along a roof, and covering a seam between adjacent sheets of roofing material with the granules. A device for depositing granules on a roof may include a hopper, and a valve, where granules stored in the hopper flow directly through the valve to the roof in response to gravity when the valve is at least partially opened, and where the flow of the granules is not assisted by an agitator, an auger, or air pressure.

A high-quality coating film with a uniform thickness is produced without crush of coating particles even in a case where a wet coating material that does not require a step of drying the coating material is used, while maintaining high productivity. By providing a surface layer with an optimized hardness on the surface of a roll used for supply of a mixture coating material, a high-quality coating film with a uniform thickness can be produced, even in a case where a wet coating material that does not require a step of drying the coating material is used, while maintaining high productivity.

The present invention comprises: a support roller part rotating while supporting the lower side of a transferred sticker sheet; a half-cutting roller part provided at the top of the support roller part so as to rotate by engaging with the support roller part, and having a half cutter for cutting a printed part of the sticker sheet passing the support roller part; and an anti-adhesion fluid supplying unit for applying an anti-adhesion fluid on the surface of the half cutter coming into contact with the printed part of the sticker sheet.

A branch location is arranged close to a nozzle, and the channel lengths are the same. A processing nozzle that includes a beam path for passing light from a light source and ejects a fluid containing a processing material from an ejection port includes a supply pipe that is arranged outside the beam path through which the light passes, and supplies the fluid, and a first branch pipe and a second branch pipe that supply the fluid from the supply pipe to the ejection port, and have the same total length. The first branch pipe includes a first bent portion having a first shape on an upstream side of the fluid, and a second bent portion having a second shape on a downstream side of the fluid, and the second branch pipe includes a third bent portion having the first shape on the upstream side of the fluid, and a fourth bent portion having the second shape on the downstream side of the fluid.

An application system component is provided in the form of a changeable application member such as a nozzle or a bell cup. The application system component includes a transponder for storing component data, from which the component data is readable, and a wear detection device for monitoring of the application system component. The wear detection device includes a wear mark and an optical detector.

An apparatus decorates manufactured articles via thermosetting powder paint. The apparatus contains a decoration station with a plane, a decoration unit having a rotating cylinder supported by a carriage movable along the longitudinal extension of the manufactured articles, and a system for applying the paint to the cylinder and transferring the paint onto the manufactured articles. The outer surface of the cylinder has engraved cavities, which represent the pattern to be reproduced on the manufactured articles and are designed to contain the paint. The system has a reservoir to contain the paint, which contacts the outer surface of the cylinder and is introduced into the cavities. The reservoir has a bottom with a free end placed close to the outer engraved surface of the cylinder to identify a point for the fall of the paint from the cavities to the manufactured articles during the rotation of the cylinder.
