Disclosed are methods and systems for continuously coating food pieces. The methods include a steps of directing and uncoated food stream through an enrober to apply a first coating to at least a portion of a surface of each food piece to form a coated stream and continuously redirecting a portion of the coated stream back through the enrober along with the stream of uncoated food pieces to apply at least one additional coating to the portion of the coated stream.

An arrangement in a curtain coater for starting and stopping coating of a web, having a reservoir and a connected surface extending over the web toward the curtain to collect the coating as the coater moves over the web to start coating the web. A cover plate that swing around a cross-direction shaft connected to the cover plate. In one embodiment the shaft also moves in the machine direction. The cover plate is used to protect an leading edge of the collecting surface from being covered with coating and pivots to be cleaned with fluid which may be supply from the shaft. The cover plate is arranged so the fluid drain off the cover plate onto the collecting surface or reservoir. When clean, the cover plate is repositioned to protect an leading edge of the collecting surface during the next start or stop operation of coating the web.

An installation for forming a compact film of particles on a surface of a carrier fluid, including: a zone acting as a reservoir of carrier fluid; an inclined ramp; a particle storage and transfer zone situated extending from the inclined ramp; a mechanism moving the fluid; a mechanism dispensing the particles in solution, configured to dispense the particles at the surface of the carrier on the surface of the carrier fluid in the zone acting as a reservoir; and a mechanism raising a level of the carrier fluid by capillary effect, arranged at a junction between the zone acting as a reservoir and the inclined ramp.

Provided is a coating apparatus that allows high-quality coating by causing a coated object to pass through a falling curtain of paint without vibrating the coated object. A coating apparatus 1, which coats a surface of a plate-shaped coated object M, includes: a table 10, on which the coated object M is disposed; a flow coater head 20, from which a curtain of paint P falls; a gutter-shaped liquid receiver 30, which is disposed below the flow coater head 20 and which collects the paint P falling from the flow coater head 20; and a horizontal conveying portion 41, which conveys the table 10, on which the coated object M is disposed, in a horizontal direction to pass through the paint P falling from the flow coater head 20.

A liquid knife cleaning apparatus and a liquid knife are provided. The liquid knife cleaning apparatus includes: a frame configured to be arranged on the liquid knife and be capable of reciprocating in an extending direction of the knife edge; a cleaning blade configured to extend into the knife edge of the liquid knife and be capable of reciprocating inside the knife edge under the driving of the frame to clean the knife edge, the cleaning blade being arranged on the frame; and a movable mechanism configured to control the frame to reciprocate on the liquid knife in the extending direction of the knife edge, the frame being connected to the movable mechanism.

The present disclosure relates to a method for coating a coiled sucker rod, the method comprising: (a) transferring the coiled sucker rod from a first reel to a thermal spray metal gun system with a conveyance system; and (b) applying a thermal spray metal coating on the coiled sucker rod with a thermal spray metal gun system to form a thermal spray metal coated coiled sucker rod.

A method of coating an active material for a secondary battery according to one embodiment of the present disclosure is a method of coating an active material on an electrode current collector of a secondary battery, the method comprising the steps of: disposing a guide member on each of the left and right sides based on a moving direction of the electrode current collector, and coating the active material onto the electrode current collector between the two guide members.

A method of coating an active material for a secondary battery according to one embodiment of the present disclosure is a method of coating an active material on an electrode current collector of a secondary battery, the method comprising the steps of: disposing a guide member on each of the left and right sides based on a moving direction of the electrode current collector, and coating the active material onto the electrode current collector between the two guide members.

A curtain application unit for applying a liquid or pasty application medium to at least one surface of a moving material web, in particular a fibrous web, includes an application head having at least one separation edge extending substantially over the width of the application head. The application medium exits the application head in the form of a free-falling curtain at the separation edge. At least one rinsing device is used to apply a flowing gaseous rinsing medium to the at least one separation edge, and at least one blocking device is suitable for keeping air movements of the ambient air away from the curtain. A method for coating a moving material web is also provided.

A curtain applicator for applying a liquid or pasty application medium to at least one surface of a running material web, in particular a fibrous web. The curtain applicator has an applicator nozzle, in particular a slotted nozzle, which under the effect of gravity, and optionally with further forces, is suitable for dispensing a single-tier or multi-tier curtain onto the surface of the material web. The curtain applicator further has a wiping device which is suitable for keeping entrained air carried by the material web away from the curtain. Moreover, there is provided at least one further blocking device which is suitable for keeping air movements of the ambient air away from the curtain.
