A method for producing a multilayer film including at least two layers joined by a two-component adhesive includes the following steps: spreading a first component A of a two-component adhesive on a first face of a first layer of film; spreading a second component B of the two-component adhesive on a first face of a second layer of film; bringing the first and second faces of the first and second layers into mutual contact joining the components and to form an adhesive and join the two layers in a multilayer film; and winding the multilayer film obtained.

Methods and apparatuses for applying coatings on a baggy web are provided. A Mayer rod and a back-up roll engage with each other to form a nip. The back-up roll has a deformable inner layer with a surface thereof covered by a deformable outer layer. The Mayer rod and the flexible web at a contacting area are impressed into the back-up roll with a machine-direction nip width W and a nip engagement depth D, which enables formation of a coating having a substantially uniform thickness.

The present invention provides an adhesive layer coating unit configured to continuously apply an adhesive layer having a first width in a longitudinal direction of a first separator. The adhesive layer coating unit comprises: a transfer roller configured to support a bottom surface of the first separator and transfer the first separator; a discharge roller configured to transfer the first separator, which has passed through the transfer roller, in conjunction with the transfer roller while supporting a top surface of the first separator, wherein a coating groove having the first width and a closed curve shape is formed in a circumferential surface of the discharge roller; and a coating member configured to inject an adhesive into a space between the discharge roller and the top surface of the first separator which has passed through the transfer roller.

As the adhesive flows in the coating groove of the discharge roller, the adhesive layer having the first width is continuously applied on the top surface of the first separator.

The present invention comprises: a support roller part rotating while supporting the lower side of a transferred sticker sheet; a half-cutting roller part provided at the top of the support roller part so as to rotate by engaging with the support roller part, and having a half cutter for cutting a printed part of the sticker sheet passing the support roller part; and an anti-adhesion fluid supplying unit for applying an anti-adhesion fluid on the surface of the half cutter coming into contact with the printed part of the sticker sheet.

The present disclosure relates to a hot glue unit for a labeling machine in the beverage processing industry. The hot glue unit includes a housing, a glue roller disposed in an interior of the housing, a glue container, and a filter unit including an extractor connected to the housing. The extractor is to extract gases from the interior of the housing and supply the gases to the filter unit before the gases are to exit the hot glue unit.

Provided are a gravure coating device for preparing a large-width ultrathin metal lithium strip and the preparation method, relating to the technical field of preparation of metal lithium materials. The device comprises: a lithium-melting tank (17), a micro-gravure roller (5), a unwinding device, a substrate back roller (7), a hot pressing device and a winding device; wherein the lower portion of the micro-gravure roller (5) is immersed into the liquid lithium in the lithium-melting tank (17); one side of the micro-gravure roller (5) is provided with a hot scraper (6), and the end portion of the hot scraper (6) is in contact with the surface of the micro-gravure roller (5); the substrate back roller (7) is arranged diagonally above the micro-gravure roller (5); the unwinding device is arranged on one side of the substrate back roller (7); the winding device is arranged above the substrate back roller (7); the hot pressing device is arranged between the substrate back roller (7) and the winding device; after passing through the substrate back roller (7) and the hot pressing device, the substrate on the unwinding device is winded onto the winding device. The device is simple in structure and reasonable in design, effectively improves the coating uniformity, and realizes automatic production of ultrathin metal lithium strips with a thickness of 1-50 μm, thereby greatly improving work efficiency and product quality.
