According to one embodiment, a coating head includes a coating bar, nozzles, a first member, second members, third members, elastic members, and a position controller. The coating bar faces a coating member. The nozzles supply a liquid toward the coating bar. The first member includes first recesses. A portion of the nozzles is between the first recesses and the third members. The portion of the nozzles and the third members are fixed to the first member by the second members. The elastic members are located in at least first, second, or third positions. The first position is between the third members and the second members. The second position is between the portion of the first recesses and the nozzles. The third position is between the portion of the nozzles and the third members. The position controller controls a relative position between the coating bar and the nozzles.

An apparatus is disclosed for coating a surface that is movable relative to the apparatus with a layer of metallic particles or particles having a metal-like appearance and reflectivity, the particles adhering more strongly to the surface than to one another. The apparatus comprises at least one spray head for directly or indirectly applying to the surface a fluid stream within which the particles are suspended, a housing surrounding the spray head(s) and defining an interior plenum for confining the fluid stream, the housing having a rim adjacent the surface that is configured to prevent egress of particles from a sealing gap defined between the rim of the housing and the surface to be coated, and a suction source connected to the housing to extract from the plenum the sprayed fluid and particles suspended in the sprayed fluid. In operation, the suction source extracts substantially all particles that are not in direct contact with the surface, so as to leave only a substantially single particle layer adhering to the surface on exiting the apparatus.

A system may include: a coating form roller; a metering roller adjacent to the coating form roller; and a sealing chamber. The sealing chamber may include first and second blades that engage with the coating form roller and the metering roller, respectively.

The present invention relates to an apparatus of manufacturing an aerogel sheet. The apparatus of manufacturing the aerogel sheet includes: a fixing vessel into which a blanket is inserted; and an impregnation device putting a silica sol precursor into the blanket inserted into the fixing vessel to impregnate and gelate the silica sol precursor, wherein the impregnation device includes a rotation roller moving from one end to the other end of a top surface of the blanket while rotating to put the stored silica sol precursor into the blanket and thereby to impregnate and gelate the silica sol precursor.

In a foil transfer device, a controller causes a sheet to be conveyed by conveyor rollers to reach a transfer position in which a foil film and the sheet are to be nipped between a heating roller and a pressure roller (of which one is called “first roller”, and the other is called “second roller”), while the first roller is positioned in a release position, separated from the second roller, and a state of transport of the foil film is kept in a restricted state by a film-transport regulator. The first roller is moved and positioned in a nipping position while the sheet is laid on the transfer position and before a foil transfer area of the sheet reaches the transfer position. The state of transport of the foil film is changed from the restricted state to a release state after the first roller gets positioned in the nipping position.

A system for coating a continuous sheet (1), having an application roller (10) for applying a coating on the sheet (1) when the sheet (1) is pressed against the application roller (10) by an application pressure element (11), a smoothing roller (20) for smoothing the coating applied on the sheet (1) by contact of the smoothing roller (20) with the coating when the sheet (1) is pressed against the smoothing roller (20) by a smoothing pressure element (21), the application (11) and smoothing pressure elements (21) being independently movable in order to press the sheet (1).

A multi-slot die coater may improve a problem that is structurally vulnerable to deformation and torsion. The multi-slot die coater including a lower slot and an upper slot includes a lower die block; an intermediate die block disposed on the lower die block to form the lower slot therebetween; and an upper die block disposed on the intermediate die block to form the upper slot therebetween, wherein at least one of the lower die block, the intermediate die block, and the upper die block comprises a metal coating layer on a ceramic body.

The present invention relates to a spreading machine for roller leather finishing. The machine includes a drawing cylinder and an engraved spreading cylinder. The drawing cylinder acts as a driving roller for a rubber conveyor belt wound between the driving roller and an idle roller. The drawing cylinder has a conveying surface and a rubber layer. In each operating configuration, the conveying surface of the rubber conveyor belt is tangent to the engraved spreading cylinder in a point of tangency (P), and the idle roller has a leather-detachment roller having a diameter within the range of 10 and 80 mm.
