Improved apparatus and methods for filtering and applying coating fluids onto substrates. The apparatus and methods are useful for casting embossed sheeting, and in fluid application dies. Improved fluid filtration methods, apparatus, elements and media are also disclosed. An apparatus and method for collection of mist generated in high speed liquid film splitting processes are also disclosed.

The invention relates to applying a liquid to pasty hot-melt adhesive to a substrate (44), comprising a template (29), having at least one cavity (38) for the hot-melt adhesive, and also comprising an adhesive-transfer infeed (33), which is assigned to the template (29) and through which the adhesive can be introduced into the cavity (38). The special feature consists in that the apparatus (10) further comprises a transporting-fluid-supply opening (35), assigned to the template (29), and a device for displacing (13, 15), in particular pivoting, the template (29) between a first position, in which the cavity (38) is assigned to the adhesive-transfer infeed (33), and a second position, in which the cavity (38) is assigned to the transporting-fluid-supply opening (35), and therefore the adhesive, in the second position, can be discharged from the cavity (38) by a transporting fluid flowing through the transporting-fluid-supply opening (35).

A hybrid scaling and patterning apparatus for producing thin films with multi-material, customized patterns is disclosed. The apparatus includes a slot die body integrated with multiple inlets and corresponding converging channels passing materials through the die body in a planar, continuous laminar flow. The hybrid scaling and patterning apparatus may be used in a method of preparing multi-material, patterned thin film materials.

Method of designing and manufacturing a distributor bar for use in a production line comprising a mixing head for providing a viscous foamable liquid mixture, a laminator with a predefined speed of at least 20 m/min, the distributor bar having a central inlet fluidly connected to a number of outlets via a main channel. The method comprises: choosing (3001) a geometry for the distributor bar and defining a set of geometrical parameters; assigning (3002) values to said parameters; creating (3003) a virtual model; simulating (3005) flow in said model by performing a Computational Fluid Dynamics simulation (CFD), taking into account (3004) a non-Newtonian shear thinning model; e) evaluating the simulated flow; building (2007) a physical distributor bar. A distributor bar, a production line, and a computer program product.

A hot melt adhesive system includes an adhesive supply for receiving solid or semi-solid hot melt adhesive, and a heater associated with the adhesive supply for melting the solid or semi-solid hot melt adhesive into liquid hot melt adhesive. An adhesive tracking system monitors an output of the liquid hot melt adhesive, and includes a flow meter having a flow inlet and a flow outlet. The flow meter measures an amount of the adhesive flowing out of the flow outlet. A product detector may be used to sense a presence of a product to which the adhesive is applied. A controller then determines the total amount of the liquid adhesive dispensed and the average amount of liquid adhesive dispensed per product.

An air manifold for a material dispensing applicator is described. The air manifold has an inlet to receive pressurized air from a pressurized air source, a channel extending therethrough from the inlet, and a plurality of passages in fluid communication with the channel. The air manifold also includes a plurality of pneumatic bolts, where each of the plurality of pneumatic bolts is disposed in a respective one of the plurality of passages and attached to a respective one of the plurality of dispensing modules of the applicator. Each of the plurality of pneumatic bolts directs the pressurized air from the channel of the air manifold to the respective one of the plurality of dispensing modules.

A jetting device and/or fluid module include a module body defining a passageway extending through the module body and also partially defining a fluid chamber, a nozzle supported by the module body, a valve element at least partially within the fluid chamber, a biasing element contacting the valve element and also contacting the module body, and a sealing member contacting the periphery of the valve element and configured to partially define the fluid chamber. The nozzle defines a fluid outlet that is in fluid communication with the fluid chamber. The valve element has an upper portion outside of the fluid chamber that is adapted for contact with the drive pin, and the biasing element is configured to apply a spring force to the valve element. The valve element is configured to cause a droplet of the fluid to be jetted from the fluid outlet when the valve element is moved in the direction toward the nozzle.

Exemplary coating devices and exemplary coating methods for coating components with a coating agent, e.g., for painting motor vehicle body components with a paint, are disclosed. An exemplary coating device comprises an application device that applies the coating agent. The application device may include a paint head that discharges the coating agent out of at least one coating agent nozzle.
