The invention relates to a biaxially oriented polypropylene film (BOPP) comprising layers (A) to (D), wherein layers (B) to (D) contain biaxially oriented polypropylene and layer (A) contains polyurethane and nanoparticles and has a layer thickness of 25 to 300 nm, layer (B) contains polymers with functional groups that are capable of forming covalent bonds with polyurethane and is directly connected to layer (A), layer (C) has at least a layer thickness of 50% of the total thickness of the film, and layer (D) represents an outer layer of the film containing an anti-blocking agent. The invention also relates to a method for producing films of this type.

A gluing system for applying glue on products is disclosed. The gluing system includes a glue applicator configured to deposit melted glue on products, a glue container configured to contain excess melted glue discharged from the applicator and fresh melted glue, a glue delivering unit configured to deliver glue from the container to the applicator and a glue discharging unit configured to convey excess glue not used by the applicator to the container. The container is divided by a partition into a first chamber, containing the fresh melted glue, and into a second chamber containing the excess melted glue and separated from the first chamber. The partition includes a filter allowing flow of the fresh melted glue and the excess melted glue from both the first and second chambers to the delivering unit.

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.

According to one embodiment, a coating head includes a coating bar, nozzles, a first member, second members, third members, elastic members, and a position controller. The coating bar faces a coating member. The nozzles supply a liquid toward the coating bar. The first member includes first recesses. A portion of the nozzles is between the first recesses and the third members. The portion of the nozzles and the third members are fixed to the first member by the second members. The elastic members are located in at least first, second, or third positions. The first position is between the third members and the second members. The second position is between the portion of the first recesses and the nozzles. The third position is between the portion of the nozzles and the third members. The position controller controls a relative position between the coating bar and the nozzles.

Paper is disclosed for use in making repositionable or removable adhesive labels. The adhesive can be applied in patches or discrete areas to the paper or to a layer of material that cleans rollers in the manufacturing line and/or in printers. The adhesive can be applied in single or multiple layers. The paper is light weight paper and preferably thermal paper for use in POS printers.

A lubricator 2 supplies an unwound coil material as an alloy plate material 11 to a metal beverage can production line for forming the alloy plate material 11 into a metal beverage can. The lubricator 2 includes: a felt roll 21 configured to contain lubricating oil in a first outer circumferential section, a felt roll 22 with a second outer circumferential section, a plate material lift configured to switch between a first state in which the alloy plate material 11 contacts the first outer circumferential section of the felt roll 21 and the second outer circumferential section of the felt roll 22, and the first outer circumferential section and/or the second outer circumferential section apply the lubricating oil to the alloy plate material 11, and a second state in which the felt roll 21 and/or the felt roll 22 applying the lubricating oil in the first state are idly rotatable by separating from the alloy plate material 11, and an air receiving section configured to apply a driving force to the idly rotatable felt roll 21 and/or the idly rotatable felt roll 22 in the second state as switched by the plate material lift.

A pre-lubricated stock sheet and a method and system for making the same are described. The pre-lubricated stock is generally in a coil wound form. The stock sheet can have opposing first and second sheet surfaces joined together by opposing side edges and opposing ends. Typically, the first and second sheet surfaces are substantially smooth and planar, wherein the sheet has 3 mg/foot.sup.2/side to about 200 mg/foot.sup.2/side of a solid lubricant having a melting temperature from about 80 to 212 degrees Fahrenheit. Moreover, the opposing side edges usually are substantially free of the solid lubricant. In some configurations, the stock sheet is an aluminum stock sheet, more particularly an aluminum can stock sheet. Furthermore, the lubricant can be in some configurations a food grade lubricant, that is qualifies a low volatile organic compound under one or more of municipal, state and federal governing authorities.

Example implementations relate to selectively deflecting substrates. One example implementation includes an apparatus to selectively lift a part of a substrate away from a transfer member when the substrate is advancing in a substrate coating system relative to the transfer member, such that, across a width of the substrate, a first part of the substrate is coated by the transfer member and a second part of the substrate, that is lifted by the apparatus, remains uncoated.

A method for manufacturing an electrode for secondary battery, including a pressing process in which a load is applied to an electrode active material slurry when the solid content of the electrode active material slurry is 70 wt % to 98 wt % during the process of drying the electrode active material slurry coated as one or more layers on a current collector. An apparatus for manufacturing the same is also provided.

A separator coating apparatus for coating an organic slurry on a separator, the apparatus including a coating bar that rotates in a transferring direction of the separator and coats the organic slurry on the separator; a bar holder spaced apart from the coating bar such that gap is present between the bar holder and the coating bar, the organic slurry being supplyable into the gap and onto the rotating coating bar; a coating block that supplies the organic slurry into the gap through a supply passage at both sides of the bar holder relative to the transferring direction of the separator; and a supporter that is on the bar holder and facing the coating bar.
