A roller coater for applying paint to mainly flat panels having different lengths includes a feed roller, an application head having applying roller and a dosing roller, and a panel conveyor. The feed roller has a cover, and the application head has vertical and a horizontal covers. Rotation supports enable a coupling and decoupling of the ends of the applying roller, and translation organs provide for withdrawing the applying roller along a L-shaped path, so as to cause an initial horizontal translation with a radial distancing, and a vertical translation. The translation organs include a vertical guide and a lifting organ for the applying roller, and removable coupling terminals at the ends of the applying roller. The interaxial distance between the feed and the applying rollers is at least equal to the length of the initial translation from the rotational supports, and shorter than the minimum length of the panels.

Provided are a method and an apparatus for producing a film with a coating solution including a material whose performance is deteriorated by oxygen functional film, without performance deterioration. The apparatus for producing a functional film includes a coating device which has a backup roller and a die coater and applies a coating solution having a dissolved oxygen concentration of 1000 ppm or less and including 10000 ppm or less of an organic solvent to a flexible support transported in a state where the support is wound around the backup roller to form a coated film, a lamination device which laminates a coated surface of the coated film and the film on the backup roller, and an inert gas atmosphere forming device which forms an inert gas atmosphere in a space including the coated surface from a coating start position to a lamination start position on the backup roller.

A system for preventing overflow of adhesive applied to a PET rolling film includes a drive unit, a detection unit, and a processing unit. The detection unit detects whether UV adhesive spread on a PET film flows out to limit lines on the PET film. The detection unit generates trigger signal upon detecting that the UV adhesive on the PET film flows to any of the limit lines, and then transmits the trigger signal to the processing unit. The processing unit controls the drive unit to accelerate a rotational speed of a guide roller for the PET film upon receiving the trigger signal from the detection unit, so as to accelerate a moving speed of the PET film.

A method of depositing a fluid onto a substrate. The method can include the steps of: providing a substrate; providing a fluid; providing a rotating roll comprising an exterior surface wherein the rotating roll rotates about the central longitudinal axis and an exterior surface defines an interior region; providing a vascular network to supply the fluid from the interior region to the exterior surface of the rotating roll in a predetermined path; transporting the fluid to the vascular network; controlling the flow of the fluid to move the fluid at a predetermined flow rate to at least one of the at least two fluid exits; and contacting the substrate with the fluid.

A unit for spreading an adhesive onto a moving film, includes at least one pair of abutments (11) upon which is mounted a first pick-up roller (12) for collecting a quantity of adhesive from a collection zone (13), a second roller (14) that rotates in contact with the first roller (12), intended to receive the quantity of adhesive, and a third roller (15) that rotates in contact with the second roller (14), wherein the abutments include at least one fixed portion (19) and one moving portion (20, 21) that can be firmly connected to the fixed portion, the moving portion being configured: to house a tank (17) in which the adhesive collection zone is found, or to house an additional fourth roller (18) positioned at a given distance from the first roller, the collection zone being located in the upper space between the first and the fourth roller (12, 18).

A coating applicator tool head configured for use with a robotic maintenance device includes a tool head body with a frame, a supply container, a drive for actuating delivery of flow of coating from the supply container, a feed tube, a nozzle receiving flow from the feed tube, and a spreading tool such as a roller brush or a spatula receiving flow from the nozzle. The coating applicator tool head is moved by an articulated arm of the maintenance device over surface of a wind turbine blade containing damage such that the roller brush or spatula can apply layers of the coating to cover and fill in the damage. The nozzle directly supplies coating continuously onto the roller brush or the spatula, and the drive can be configured to independently adjust supply of two or more different components in the supply container that may be mixed to form the coating.

A method for coating a flat substrate by a coater includes a control system receiving print job data and print job settings, the control system determining a suitable impression of an application roller by means of received print job settings, a first sensor determining a radius of the application roller, determining an axis location of the application roller having a distance of the radius of the application roller plus a nominal thickness of the flat substrate read from the print job data minus the determined suitable impression from the supporting roller surface, automatically moving the application roller to the determined axis location, and starting a transport of the flat substrate from an entry station in-between the supporting roller and the application roller towards an end station.

A gluing station for applying glue to product elements guided in a product stream is intended to permit continuation of the production process and gluing of the product elements in a particularly simple and reliable manner even after a temporary machine stop or production standstill. For this purpose, according to the invention, a moistening system is assigned to a glue application roller that can roll on the product stream. During operation of the gluing station, in the event of a stopped product stream, the glue application roller is pivoted away from the product stream and the transfer roller for the duration of the standstill and is kept rotating, whereby the surface of the glue application roller is moistened.

A treatment-agent liquid applicator includes an application roller to apply a treatment agent to a medium to be conveyed to an image forming apparatus, a pressure roller to press the medium against the application roller, a supply roller to supply the treatment agent to the application roller, and circuitry configured to rotate the application roller for a duration of time, from when job information is acquired by the image forming apparatus, to when the medium reaches the application roller.
