Methods and apparatuses for applying coatings on a moving web are provided. A coating die and a back-up roll engage with each other. The back-up roll includes a shell rotatably supported by a pressurized air layer. When a coating material is dispensed from the coating die onto the web to form a liquid coating, the pressure of the air layer is controlled such that the shell translates in space to balance forces from the air layer and the coating bead, while the web is being translated to drive the shell.

An installation for impregnating a porous substrate by transfer of powder, including an area for storing the powder, and an endless conveyor capable of being moved, which includes an external surface containing cavities. The external surface of the conveyor delimits an edge of the storage area to fill said cavities with the powder. The installation comprises a positioner for holding the porous substrate in contact with a fraction of the conveyor length, to seal cavities containing the powder. A drive device enabling to move the conveyor and the porous substrate, and means for displacing the powder are arranged opposite said fraction of the conveyor length, to at least partly displace a portion of the powder across the porous substrate.

Described and recited herein are example embodiments and implementations of a paper product dispenser by which the paper product may be dampened or moistened as it unrolls, based on at least the angle at which the paper product is unrolled.

A sealant system for operation with a metal workpiece comprises a frame, a cam assembly mounted to the frame, a sealant reservoir, a sealant application unit connected to the sealant reservoir, and a control module for coordinating operation of the cam assembly and the sealant reservoir, wherein the control module comprises a temperature sensor for monitoring the temperature of the sealant, an integrated heating system for heating the sealant and a controller in communication with the temperature sensor and the integrated heating system.

A coating module to coat a substrate with a coating composition includes a coating device to apply a layer of coating composition on the outer surface of the substrate, and a flexible film including a distal portion designed to be in contact with the coated substrate.

A continuous coating device for continuously conveying a long film includes a coating roll, an imaging device and a coating head. The long film is wound onto the coating roll. The imaging device is configured to capture an image of a mark or a pattern on the long film wound onto the coating roll. The coating head is configured to coat the long film wound onto the coating roll with a specific pattern. The coating head is disposed downstream from the imaging device in a conveyance direction of the long film.

According to one embodiment, a system for manufacturing a polymethyl methacrylate (PMMA) prepreg includes a mechanism for continuously moving a fabric or mat and a resin application component that applies a methyl methacrylate (MMA) resin to the fabric or mat. The system also includes a press mechanism that presses the fabric or mat during the continuous movement subsequent to the application of the MMA resin to ensure that the MMA resin fully saturates the fabric or mat. The system further includes a curing oven through which the fabric or mat is continuously moved. The curing oven is maintained at a temperature of between 40 C. and 100 C. to polymerize the MMA resin and thereby form PMMA so that upon exiting the curing oven, the fabric or mat is fully impregnated with PMMA.

The invention relates to a device for producing an adhesive tape (2), comprising a supply unit (5) for supplying a strip-type textile carrier (3) of the adhesive tape (2), and a coating unit (6) for applying an at least lamellar adhesive coating (4) to at least one side of the carrier (3). The invention also relates to an ultrasound unit (9 and 10) and/or a laser unit for producing perforations and/or cut edges in the carrier (3).

A system and method is provided for creating a structure including a vasculature network. A film deposition device is configured to dispense droplets onto a surface of a substrate to form a curable fugitive pre-patterned liquid film on the surface of the substrate. An electrohydrodynamic film patterning (EHD-FP) device has a patterned electrode structure formed to generate an electric field and to subject the film on the surface of the substrate to the electric field. The film thereby being formed by the EHD-FP into patterned features in response to being subjected to the electric field. Then a casting system is configured to cover the patterned features in an epoxy to form patterned structures, wherein the patterned structures comprise a fugitive vasculature structure.

A method for coating a surface of a substrate may involve coating the surface of the substrate with a wet coating by way of a coating station, conveying the substrate by way of a conveying device, and detecting the surface coated with the wet coating by producing a thermal image of a detection region that comprises part of the surface. The thermal image may be recorded in a spectral range that includes a wavelength between 1 micrometer and 20 micrometers. Further, the detection region may be located directly downstream of the coating station, or the detection region may at least partially include the coating station.
