A printing apparatus includes an image forming unit that forms an ink image, a transfer unit that transfers the ink image formed on a transfer member to a print medium in a transfer operation, and a liquid absorbing member that absorbs a liquid component from the ink image before the transfer operation. A recovery unit recovers absorption performance of the liquid absorbing member by applying a moisturizing liquid to the liquid absorbing member. A first estimation unit estimates, based on print data, an ink discharge amount of ink to form the ink image, and a second estimation unit estimates a liquid amount of the liquid component to be absorbed by the liquid absorbing member from the estimated ink discharge amount. In addition, a control unit controls an application amount of the moisturizing liquid by the recovery unit based on a result of estimation by the second estimation unit.

A coater assembly includes an array of side-by-side selectively closable slot portions to control pressurized fluid flow onto a substrate during relative movement between the coater assembly and the substrate to form a coating pattern on the substrate. A control module produces the coating pattern via control over selective independent closure of the slot portions based on a mapping matrix of individually addressable coatable elements.

In a roller transfer application method for a hot-melt adhesive, a coater head having a slot in a direction towards an axis center of a pattern roller is provided to face a pattern surface of the pattern roller; and by supplying hot-melt adhesive, which is supplied from a hot-melt adhesive supply device, in a thin-film state to a pattern top surface of the pattern roller, thin-film hot-melt adhesive is thus only supplied to the top surfaces of protrusions of the pattern roller. By opening an on-off-type hot-melt adhesive supply control valve, which is attached to the coater head, at a timing that an adhesive opening (the slot) on the bottom surface of the coater head faces application zones on the pattern surface of the pattern roller, the hot-melt adhesive is supplied only to the top surfaces of the pattern roller protrusions.

A tandem system of metering and donor rolls is used to apply two different adhesives to a fully adhesive backed multilayer sheet to produce variably distributed adhesives and properties. Each of the two adhesives is unique and is cured differently to create a layer of adhesive that has differing adhesive properties on the sheet. A clear adhesive is applied to a top portion of cards before they are cut from the sheet and has a higher tackiness than the adhesive applied to the rest of the cards on the sheet in order to reduce glue buildup on blades cutting the cards from the sheet.

A device for applying a treatment substance to a running paper web or board web (11) by means of at least one curtain applicator (2.1, 2.2) comprising a curtain coating die for applying the treatment substance to an applicator roll (6, 7) which, together with a second roll (6, 7), creates a treatment nip (15) in which the treatment substance is transported from the applicator roll (6, 7) to the respective side of the paper web or board web (11), and the curtain coating die has a slot adjustment (3.1, 3.2) for adjusting an exit slot (14.1, 14.2). To provide a device for applying treatment substances which improves the paper/board quality differently prepared treatment substances can be supplied to the at least one curtain coating die, and the curtain applicator (2.1, 2.2) combines the two operating modes of a film operation mode and a sump operation mode by providing an electrically and/or mechanically actuable adjusting device for the slot adjustment (3.1, 3.2) applied to the exit slot (14.1, 14.2) of the curtain coating die, which controls a die lip and sets the exit slot (14.1, 14.2) alternatively to 100 m to 500 m for a film operation mode or to 500 m to 2.0 mm for a sump operation mode, so that the at least one curtain applicator (2.1, 2.2) is designed to be performed with two different operating modes.

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 spray gun adapter establishes fluid communication between a fluid pump of a handheld airless spray gun and an applicator accessory. The adapter comprises an adapter body, a head attached to the adapter body, and a protrusion. The adapter body comprises an upper portion, a lower portion, a radial inlet located in a sidewall of the adapter body between the upper and lower portions, and an adapter bore having a first diameter in fluid communication with the radial inlet. The head comprises a cavity in fluid communication with the adapter bore and having a second diameter larger than the first diameter, an adapter outlet located in the upper portion of the adapter body and in fluid communication with the cavity, and a handle extending radially from the head. The protrusion extends radially from the adapter body between the upper and lower portions of the adapter body.

A system for applying a product (3) by roller is disclosed. The system has an applicator roller (1) for applying a product (3) on a substrate (4) and a first dosing roller (2) for dosing said product (3) on the surface of the applicator roller (1), wherein the system comprises at least one second dosing roller (2) configured to fine-tune the dosing performed by the first dosing roller (2), thereby adjusting the amount of product (3) dosed on the surface of the applicator roller (1).

An applicator is disclosed for applying sealant to a moving substrate. The applicator includes a wheel having a periphery. A plurality of spaced apart footprints extends around the periphery of the wheel and each footprint has a sealant receiving feature. A reservoir is provided for containing a supply of sealant to be applied to the moving substrate. The wheel is rotatably mounted at least partially in the reservoir such that as the wheel rotates, each of the spaced apart footprints repeatedly moves through a supply of sealant in the reservoir to pick up a charge of sealant, around one side of the wheel toward the moving substrate, adjacent the moving substrate to transfer the sealant charge to the substrate, and around the other side of the wheel back toward the supply of sealant. At least one stop is formed on each of the footprints for inhibiting sealant picked up by the footprint from being urged rearwardly on the footprint by high speed rotation of the wheel. A backstop may be formed at a trailing end of each footprint and mid-stops may be formed between a leading end of each footprint and the trailing end.

A coating device for supplying a liquid to a substrate, particularly in the form of an optionally printed web, foil, strip or sheet, comprises a reservoir for holding a quantity of liquid. A coating assembly is provided which is able and configured to take liquid from the reservoir and transfer it to the substrate. A supply delivers the liquid into the reservoir during operation. The supply is controllable and is able to lead a constant liquid flow into the reservoir. The reservoir is provided with a level detector capable and configured to detect a liquid level in the reservoir. Provided between the level detector tools and the coating assembly is a control which controls the coating assembly during operation on the basis of a detection (LS) of the liquid level in the reservoir in order to maintain the liquid level at a fixed value.
