The coater has a coiled material connection mechanism that includes an upper rack (2) and a lower rack (3). A vacuum suction plate I (2-3) provided with a driving device for achieving displacement and a vacuum suction plate II (3-1) provided with a solid glue spraying device (3-3) are respectively disposed on the bottom of the upper rack (2) and the top of the lower rack (3). An optical fiber sensor I (2-4) and an optical fiber sensor II (3-2) are respectively disposed in the vacuum suction plate I (2-3) and the vacuum suction plate II (3-1). A tension detection device (4) is disposed between the lower rack (3) and a driving roller assembly (1).

The present disclosure relates to a slot die coating apparatus for coating an electrode active material slurry onto an electrode collector, the slot die coating apparatus including a coating roller, a die comprising a lower discharge opening, through which a first electrode active material slurry is discharged, and an upper die located on the upper side of the lower die and having an upper discharge opening, through which a second electrode active material slurry is discharged, and an upper air vent may be installed in the upper die and a lower air vent may be installed in the lower die.

A film manufacturing equipment includes a transporting device, a filtering device, a coating device, a baking device and a blowing device. Transporting device is configured to transport a substrate. The filtering device is configured to filter a solution. The coating device is configured to squeeze and coat the filtered solution on the substrate. The baking device is configured to bake the solution coated on the substrate. The blowing device is configured to blow an air to the baked solution.

A coating device includes a backup roll configured to transport a workpiece; a coating die configured to discharge a coating liquid onto the workpiece; a drive section capable configured to drive the backup roll; and a heat dissipation section configured to dissipate heat generated in the drive section.

In a coating system, two rollers are arranged adjacent to one another. A donor foil with rheological material dispensed thereon is advanced through a gap between the two rollers. Such gap spreads the dispensed material over the donor foil, coating the donor foil with a layer of the material with a uniform thickness associated with the gap width. Each roller is supported on a holder. Adjustment of the gap width may be effected by keeping the position of one of the holders fixed, while horizontally translating the position of the other holder. The position of the translatable holder may be adjusted by pistons and linear actuators. The pistons may bias the moveable holder towards the stationary holder. The linear actuators mounted on the moveable holder may extend respective arms against the stationary holder, thereby countering the biasing of the pistons and pushing the moveable holder away from the stationary holder.

Systems and methods for depositing materials on a substrate via OVJP are provided. A float table and grippers are used to move and position the substrate relative to one or more OVJP print bars to reduce the chance of damaging or compromising the substrate or prior depositions.

A coating device has: a die head that is provided with a supply port into which a coating slurry is supplied, a manifold that stores the coating slurry, and a slit that dispenses the coating slurry; a supply pipe that is connected to the supply port of the die head; and a cover plate that is provided in the supply port or the supply pipe and that reduces the flow rate of the coating slurry at the center of a cross-section that is orthogonal to the direction in which the coating slurry in the supply port or the supply pipe flows into the die head.

A device for applying liquid flavors to collagen casing is provided. In one embodiment, the device comprises a cup and a roller for applying liquid flavor to the surface of the collagen casing prior to drying. In another embodiment, the device comprises an applicator having a base plate with a first hole in the base plate to allow the collagen casing to pass through the base plate, a second hole in the base plate in fluid communication with the first hole to inject liquid flavor through the second hole into contact with the collagen casing as it passes through the first hole, a wiper removably attached to the base plate to wipe excess liquid flavor from the surface of the collagen casing, and a liquid flavor injection line attached to the second hole in the base plate. In some embodiments, the cup and roller are combined with the applicator to apply the liquid flavor.

Methods and apparatuses herein provide for the application of viscous fluids, such as adhesives, in pre-determined patterns, to an advancing substrate. The fluid applicator comprises a slot die applicator and a substrate carrier. The slot die applicator comprises a plurality of applicator channels, each applicator channel being controlled by a switching valve, and wherein the switching valves are independently switchable.
