A fluidized-bed coating method includes: immersing at least part of a workpiece in a powder coating material contained in a fluidized-bed vessel while air is introduced from a bottom of the fluidized-bed vessel at an average air flow rate of 5 mm/min or higher and 20 mm/min or lower per unit area of the bottom so that a floating ratio of the powder coating material is 5% or higher and 20% or lower, the workpiece having a temperature higher than or equal to a softening temperature of the powder coating material and lower than or equal to a melting temperature of the powder coating material; taking the workpiece out of the powder coating material; and heating the powder coating material attached to the workpiece.

A blade attachment tool includes a first support member supported by a pressing support portion supporting a blade formed of an elastic member configured to wipe/scrape liquid/solids spreading on an abutment surface by being pressed against the abutment surface and being long in one direction such that the blade is pressed against the abutment surface with a predetermined pressing force, a second support member supported to swing about a swing shaft extending in a longitudinal direction of the blade with respect to the first support member and configured such that a base end side of the blade is attached thereto, and an energizing member configured to apply a reaction force to a friction force that causes the second support member to swing about the swing shaft with respect to the first support member when the blade is pressed against the abutment surface to slide relatively to the abutment surface.

A squeegee is to be relatively moved in a certain direction while a desired gap is being formed with respect to a base material to uniformly level a thickness of a powder layer including powder supplied on the base material, and includes: a first portion that vibrates in contact with the powder on an upstream side of a relative movement direction of the base material with respect to the squeegee; and a second portion that vibrates in contact with the powder on a downstream side of the relative movement direction of the base material with respect to the squeegee, a vibration direction of the first portion being different from a vibration direction of the second portion.

A roll-to-roll manufacturing machine suitable for processing and producing polymer films that contain nanostructures, including but not limited to multifunctional polymer films. The machine applies a liquid polymer on a substrate to form a liquid polymer film, at least partially embeds nanostructures into the liquid polymer film, melt casts a layer of a molten polymer on the liquid polymer film to produce a thin polymer film, organizes the nanostructures in a thickness direction of the thin polymer film comprising applying an electric field to the thin polymer film, aligns the nanostructures in the thin polymer film by simultaneously subjecting the thin polymer film to heat and a field that aligns the nanostructures, and solidifies the thin polymer film to freeze the nanostructures along nanocolumns in a thickness direction of a solidified polymer film resulting therefrom.

The disclosure relates to an apparatus for impregnating fibers (1) with a matrix material, including a unit for soaking the fibers with the matrix material. A unit for setting the fiber content by volume (100) includes at least one opening (107) through which the soaked fibers (1) are guided. Each opening (107) includes a minimum opening cross section (111) dimensioned such that matrix material is removed such that the desired fiber content by volume is achieved. The disclosure furthermore relates to a method for impregnating fibers in the apparatus.

An additive layer manufacturing apparatus comprising a doctor blade (57) having a tip (51) which, in use, is arranged proximal to a material layer (59) to be recoated during an additive layer manufacturing method, the doctor blade (57) having a cavity (50) with an inlet and an outlet, the outlet located at the tip (51) and the inlet connectable to an air supply (53) whereby air can be directed through the cavity (50) to the outlet and onto a surface (59a) of the material layer (59).

An applicator is disclosed for applying sealant to a moving substrate. The applicator includes a wheel having a periphery. A plurality of spaced apart footprints extends around the periphery of the wheel and each footprint has a sealant receiving feature. A reservoir is provided for containing a supply of sealant to be applied to the moving substrate. The wheel is rotatably mounted at least partially in the reservoir such that as the wheel rotates, each of the spaced apart footprints repeatedly moves through a supply of sealant in the reservoir to pick up a charge of sealant, around one side of the wheel toward the moving substrate, adjacent the moving substrate to transfer the sealant charge to the substrate, and around the other side of the wheel back toward the supply of sealant. At least one stop is formed on each of the footprints for inhibiting sealant picked up by the footprint from being urged rearwardly on the footprint by high speed rotation of the wheel. A backstop may be formed at a trailing end of each footprint and mid-stops may be formed between a leading end of each footprint and the trailing end.
