A thin film deposition system includes a web guide system having a plurality of web guides defining a web transport path for the web of substrate. The web guide system includes a moveable portion including first and second moveable-position web guides. A web transport control system advances the web of substrate along the web transport path at a web advance velocity. A deposition head is located along the web transport path between the first and second moveable-position web guides. A motion actuator system synchronously moves a position of the first and second moveable-position web guides such that they move forward and backward according to a defined oscillating motion pattern while maintaining a constant distance between the first and second moveable-position web guides, thereby causing a portion of the web of media adjacent to the deposition head to move forward and backward in an in-track direction.

A treatment apparatus includes two can rolls provided on a transfer path through which a long resin film is transferred in a roll-to-roll manner in a vacuum chamber; and surface treatment means facing an outer circumference of each of the can rolls to treat a surface of the long resin film cooled by being wound around the outer circumference. The downstream can roll is provided with upper and lower two sets of feeding and sending systems, and one surface of the long resin film in contact with the outer circumference of the downstream can roll at a time when the long resin film travels through the lower one of the two sets of feeding and sending systems is opposite to the other surface of the resin film in contact with the outer circumference of the downstream can roll at a time when the resin film travels through the upper one.

Disclosed herein is a drum for roll-to-roll deposition to rotate about a longitudinal axis. The drum is circular in a widthwise cross-section and has a shape in which opposite longitudinal edge portions each have a narrower width than a longitudinal central portion. By using the drum for roll-to-roll deposition according to embodiments of the present disclosure, it is possible to remove wrinkles occurring on a flexible substrate when a roll-to-roll deposition process is performed. As a result, it is possible to manufacture a film roll having a deposition layer with excellent widthwise thickness uniformity.

The present invention is in the field of A roll-to-roll apparatus for processing metal tapes with a ceramic coating. In particular, the present invention relates to a roll-to-roll apparatus for pro-cessing metal tapes with a ceramic coating comprising at least two rolls with fixed axis position, and at least one roll with variable axis position to adjust the tape position and/or tension, wherein the position and the diameter of the rolls are adjusted to touch the metal tape only from one side and to limit the stress on the metal tape at any point such that the metal tape is not stretched by more than 0.15%.

A film deposition apparatus includes: a chamber having a film deposition gas introduced thereinto and exhausted therefrom, in which film deposition with the film deposition gas is performed on an object to be treated; and a film conveying part disposed in the chamber and conveying in a roll-to-roll manner a long film that is the object to be treated. The film conveying part includes: a rotatable roller with part of whose peripheral surface the long film comes into contact; and a nozzle pipe for spraying an inert gas onto a region of the roller, the region being not covered by the long film.

Provided are systems and methods for inducing strain fields to give rise to controllable wrinkle patterns in a variety of substrates. Also provided are articles having persistent wrinkling patterns thereon.

Provided is a gas discharge roil, which includes: an inner roll, which has a rotary shaft; an outer roll, which is fitted and integrated with an outer peripheral surface of the inner roll; gas introduction grooves, which are formed on the outer peripheral surface of the inner roll over an entire circumference thereof at substantially uniform intervals along a circumferential direction of the inner roll so as to extend along a rotary shaft direction of the inner roll, and which are configured to define gas introduction channels between an inner peripheral surface of the outer roll and the gas introduction grooves; and a group of gas discharge holes formed on the outer roll so as to penetrate through to the gas introduction channels. A circumferential cutoff rate of a gas introduction channel cross-section is 36% or less, or a porosity within a gas introduction range is 20% or less.

A roller device for guiding a flexible substrate is described. The roller device includes a support surface for contacting the flexible substrate, the support surface having a coating comprising an electronegative polymer. Further, a vacuum processing apparatus for processing a flexible substrate including the roller device and a method of processing a flexible substrate in the vacuum processing apparatus is described.

Disclosed are a high-temperature, high-performance capacitor thin film continuous production device and method. A thin film (3) to be processed is released by an unwinding roller (1), the position of the thin film to be processed is adjusted by an unwinding adjustment roller (2), such that the thin film is guaranteed to be located at the middle position of a discharge gap (12), and the thin film to be processed then passes through a plasma deposition area, the position of the processed thin film (7) is adjusted by a winding adjustment roller (4), and the processed thin film, after adjustment, is wound by a winding roller (6) after being drawn by a drawing roller (5), with the winding roller being an inflatable roller. The steady and controllable movement of the thin film in the deposition area is achieved. Large-scale continuous production, capable of matching the existing production speed of a polymer capacitor thin film, can be achieved using the device, wherein same has the advantages of flexible configuration, low environmental requirements, strong universality, a fast processing speed, low production costs and no pollution.
