A coating apparatus includes a transport roll for transporting a base material, a slit die facing a lower surface of the base material, a coating liquid supply controller for switching on and/or off in supply of a coating liquid to the slit die, and a base material height changing device for ejecting compressed gas onto the lower surface of the base material during a specific period from a termination of the supply of the coating liquid to the slit die to a restart of the supply of the coating liquid to the slit die.

A method and a vacuum-coating system for coating a band-type material, in particular made of metal. For this, the band-type material is moved, via a conveying section, in a transport direction and is vacuum-coated within a coating chamber, in which a vacuum is applied. A position of the band-type material is adjusted and/or aligned as relates to a center of the conveying section by means of at least one band position control device, which is arranged within the coating chamber.

A method and a vacuum-coating system (10) for coating a strip-shaped material (11), in particular made of metal, are disclosed. Thereby, the strip-shaped material (11) is moved over a conveying section (12) in a transport direction (T) and vacuum-coated within a coating chamber (14) in which a vacuum is applied. When viewed in the transport direction (T) of the strip-shaped material (11), at least one trimming shear (38) is arranged upstream of the coating chamber (14), with which the strip-shaped material (11) is trimmed at at least one strip edge, preferably at both strip edges, in order to produce a constant width for the strip-shaped material (11) over its longitudinal extension.

An apparatus for manufacturing a display device includes a first roller from which a film member is unwound, a second roller around which the film member is wound, a flatness maintainer that is arranged between the first roller and the second roller and keeps at least one of an upper surface and a lower surface of the film member, flat, and a sensing unit arranged on at least one of the upper surface of the film member and the lower surface of the film member and detecting droplets dropped from a head unit onto the film member.

An apparatus for applying an ultraviolet coating includes: a substantially vertically oriented frame; a first roll rotatably attached to the first side of the frame; a second roll rotatably attached to its second side; multiple nozzles disposed on the first side, above the first roll; a motor coupled to the second roll; an ultraviolet coating fluid reservoir disposed above, and coupled to, the nozzles, thereby providing the nozzles with the ultraviolet coating fluid; and an air compressor coupled to the nozzles, thereby providing the nozzles with compressed air. The ultraviolet coating fluid is provided to the nozzles solely via a gravity feed from the reservoir. In use, the motor causes sheet material, initially wound around the first roll, to advance up and over the frame and then wind onto the second roll, as the ultraviolet coating fluid is sprayed onto the sheet material by the nozzles.

To form a web conveying path that bends and conveys a web, a web conveying device has: a plurality of foil supporting members that are disposed at prescribed intervals in a conveying direction of the web and that support a surface of the web that is being conveyed; a foil extending member stretched between the foil supporting members, which pulls an end of the web downstream in the conveying direction of the web such that the web extends from a starting point to an end point of the web conveying path that is formed by the foil supporting members; and a moving mechanism that moves the foil extending member from the starting point to the end point of the web conveying path.

According to various embodiments, the temperature control roller may comprise: a cylindrical roller shell, which has a multiplicity of gas outlet openings; a temperature control device, which is configured to supply and/or extract thermal energy to or from the cylindrical roller shell; multiple gas lines made to extend along the axis of rotation; a gas distributing structure, which couples the multiple gas lines and the multiplicity of gas outlet openings to one another in a gas-conducting manner, the gas distributing structure having a lower structure density than the multiplicity of gas outlet openings.

A printing device includes a discharging roller, opposing rollers opposing the discharging roller, a discharge motor, a first coupling mechanism, a moving mechanism, and a second coupling mechanism. The first coupling mechanism rotates the discharging roller in a direction where a tape is transported downstream when the discharge motor rotates forward (arrow R1). The moving mechanism moves the discharging roller to a nip position to hold the tape with the opposing rollers and a release position spaced from the tape. The second coupling mechanism includes a one-way clutch that couples the discharge motor and the moving mechanism in a manner drivable together when the discharge motor rotates reversely (arrow R2) and decouples the discharge motor from the moving mechanism when the discharge motor rotates forward (arrow R1).

An elastic roll includes: a roll core; an inner-layer laminate covering an outer-peripheral surface of the roll core parallel to a roll longitudinal direction; a surface-layer elastomer including a tubular portion covering an outer-peripheral surface of the inner-layer laminate, and edge portions connected to the tubular portion, covering both end surfaces of the inner-layer laminate orthogonal to the roll longitudinal direction, and arranged in a manner being in contact with the roll core; and end-portion sealing structural bodies configured to press the edge portions of the surface-layer elastomer against the roll core.

A coater includes a coating device and a rotator. The coating device is configured to apply a coating liquid on a sheet material. The rotator is configured to contact a coated surface of the sheet material to which the coating liquid is applied in the coating device. The rotator has a plurality of fine particles on a circumferential surface of the rotator.
