The invention relates to a method for reducing an end face stickiness a roll (21) of adhesive tape, by supplying a precursor (4) comprising organic polyfunctional silanes to a plasma stream, directing the plasma stream enriched with the precursor (4) at the roll end face (20), and coating the roll end face (20) with an SiOx coating.

A coating apparatus can be used to concurrently coat both sides of a substrate while assuring a VOC free atmosphere outside the equipment. The coating apparatus can be used in-line, where flat materials and substrates that are typically carried along a conveyer may enter the coating apparatus, usually without requiring the substrate to be moved into any other configuration. The coating apparatus may be configured to permit the user to perform any number of treatment steps while providing isolation between the steps. The substrate can be partially suspended by the coating apparatus to permit both sides to be treated at the same time. A vacuum system, including redundant perimeter negative pressure venting ducts, can create a vacuum perimeter wall around the moving, treated material to ensure a VOC free atmosphere outside the coating apparatus.

A reusable, fiber containing pulp product is described that is highly suited for use in the manufacture of paper products. The reusable, fiber containing pulp product provides a mixture of fibers and small, dense polymer/particle fragments. The polymer/particle fragments within the reusable, fiber containing pulp product have a size range and density that facilitates efficient removal of the polymer/particle fragments using pressure screens.

Provided is a method for removing a coating film from a coated film including a coating film containing a water-soluble resin on at least one side of a base film. The method includes: supplying a cleaning liquid in a form of droplets to a surface of the coating film, and retaining the cleaning liquid in the form of droplets on the surface of the coating film; and subsequently removing the coating film containing the cleaning liquid from the coated film.

An apparatus including a first device which moves a first portion of a soft, damp, slightly pressed slab out of alignment with a majority of the slab and thus introduces a first crack in the slab; and a device for spraying a first colored material into the first crack of the slab. The first device which moves the first portion of the slab out of alignment with the rest of the slab may include a first cylinder. The device for spraying the first colored material in the first crack of the slab may include a robotic apparatus. In at least one embodiment, the apparatus may also include a second device which moves a second portion of the slab out of alignment with the majority of the slab and thereby introduces a second crack in the slab.

The invention provides a paint immersing process for insulating paper, comprising the following steps: step 1, adding insulating paint in a container to blend paint; step 2, drying a base band of the insulating paper; step 3, entirely immersing the processed base band of the insulating paper into the insulating paint; or spraying the insulating paint onto the base band to cover the surface thereof; and step 4, taking out the base band to dry at controlled temperature till solidifying the insulating paint and the base band of the insulating paper. The paint immersing process is simple and practical to operate. The base band can directly cover a conductor as an insulator. As the insulating paint has a certain adhesive property, the structure of conductor with the insulating paper becomes more stable. After the conductor is wound into a coil, free of another immersing process, simplifying production.

Provided is a matte article that has excellent matte effect visibility and texture as well as an excellent soft touch feeling. A matte article having, on at least a part of a surface thereof, a surface shape with an Spc (arithmetic mean curvature of protrusion vertexes) of more than 4000 mm.sup.?1 as specified in JIS B0601:2013 and an Rsm (average length of curve elements) of less than 30 ?m as specified in JIS B0601:2013.
