A device for applying a flowable substance to at least one substrate includes an applicator nozzle in the form of a slotted nozzle which has a stationary nozzle body with an inlet opening, a flow duct, and a nozzle slot, wherein the flowable substance is delivered through the applicator nozzle and passes from the inlet opening into the flow duct and from there to the nozzle slot, and is discharged through an outlet opening of the nozzle slot that is arranged in an outer region of the nozzle body, wherein the applicator nozzle further has a slide valve movable relative to the nozzle body in the longitudinal extent of the outlet opening by means of actuating means and contacts the outer region for modifying the covering of the outlet opening. The longitudinal extent of the flow duct is at least as great as the longitudinal extent of the nozzle slot.

An electrode coating device includes a die block including a first die and a second die coupled to each other, and at least one of the first die and the second die having an accommodating portion for accommodating slurry, a shim plate partially disposed along a circumference of the accommodating portion between the first die and the second die to form a discharge port through which the slurry is discharged, and an expansion plate coupled to the shim plate, wherein the shim plate includes: a first section, second sections, and a third section, wherein the expansion plate is disposed in a form expanding a width of the third section in a region corresponding to the accommodating portion.

A gas and liquid knife and a control method thereof are provided. The gas and liquid knife includes a chamber and a knife head. An ejection opening is provided at the knife head The knife head has a first knife lip and a second knife lip. The ejection opening is defined between a first inner wall of the first knife lip and a second inner wall of the second knife lip. The chamber is defined between the first wall plate and the second wall plate slidably connected with each other. The first knife lip connects to the first wall plate. The second knife lip connects to the second wall plate. The first knife lip and second knife lip moves relatively as the first wall plate and the second wall plate slides relatively, such that a minimum distance between the first inner wall and the second inner wall could be changed.

An apparatus (102) for applying a viscous material (162) to a surface (182) of a workpiece (180) is disclosed. The apparatus (102) comprises a channel (104) comprising an inlet (106) and an outlet (108). The channel (104) has a width CW that increases from the inlet (106) to the outlet (108). The apparatus (102) also comprises dividers (110) inside the channel (104). The channel (104) further comprises subdivisions (112) formed by the dividers (110). The subdivisions (112) of the channel (104) are in communication with the inlet (106) and the outlet (108) of the channel (104). At least one of the subdivisions (112) of the channel (104) has a width SW that increases from the inlet (106) of the channel (104) to the outlet (108) of the channel (104).

An applicator for the deposition of sealant onto a surface of a workpiece is disclosed including at least one inlet for depositing sealant on to a surface or a nozzle-receiving space for receiving a nozzle comprising at least one inlet for depositing sealant on to a surface; at least one sealant-contacting surface for contacting sealant deposited onto the surface through the inlet as the applicator is moved across said surface, thereby forming a film of sealant on the surface; at least one spacer for contacting a surface onto which sealant is to be deposited and for maintaining the sealant-contacting surface in spaced relationship with the surface; the applicator being configured to facilitate the formation of films of different widths.

A slot die coater is configured for making a coating width of a multi lane model uniform and reducing a condition adjustment loss in the subsequent production. The slot die coater includes an upper plate; a lower plate; and shims interposed between the upper plate and the lower plate and defining at least two individual lanes to form a slot. The shims defining the individual lanes include a fixing pin to improve positional precision when fixing to the upper plate or the lower plate and a fixing bolt for fixing to the upper plate or the lower plate.

A slurry distributor for use in a continuous manufacturing process includes an inlet opening and a shaped duct adapted to receive a flow of slurry provided at the inlet opening. The shaped duct has a parabolic guide surface adapted to redirect the flow of slurry. An outlet opening in fluid communication with the shaped duct is adapted to discharge the flow of slurry from the slurry distributor.

A slurry distribution system can include a feed conduit and a distribution conduit in fluid communication therewith. The feed conduit can include a first feed inlet and a second feed inlet disposed in spaced relationship thereto. The distribution conduit can extend generally along a longitudinal axis and include an entry portion and a distribution outlet in fluid communication therewith. The entry portion is in fluid communication with the first and second feed inlets of the feed conduit. The distribution outlet extends a predetermined distance along a transverse axis, which is substantially perpendicular to the longitudinal axis. The slurry distribution system can be placed in fluid communication with a gypsum slurry mixer adapted to agitate water and calcined gypsum to form an aqueous calcined gypsum slurry.

A method for manufacturing of a multilayer PVC semi-finished product, in particular a multilayer PVC synthetic leather or a multilayer PVC foam sheet, the method comprising the steps of: Coating a coated or uncoated carrier web with a PVC plastisol, whereby a carrier web coated with an ungelled plastisol layer is obtained; thereafter; gelling the ungelled plastisol layer, whereby a carrier web coated with a gelled plastisol layer is obtained; and thereafter cooling the carrier web coated with the gelled plastisol layer; characterized in that the coating comprises coating the carrier web with at least two PVC plastisols one above the other, simultaneously or in immediate succession. A corresponding apparatus is further described.
