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.

An embodiment of the present invention prevents a defect from occurring in a joint portion, in a case where a film is produced by processing a film original sheet including the joint portion. A coating device carries out processing in different manners, respectively, for a joint portion of a first porous film original sheet and a second porous film original sheet and for portions other than the joint portion.

A coating device has: a die head that is provided with a supply port into which a coating slurry is supplied, a manifold that stores the coating slurry, and a slit that dispenses the coating slurry; a supply pipe that is connected to the supply port of the die head; and a cover plate that is provided in the supply port or the supply pipe and that reduces the flow rate of the coating slurry at the center of a cross-section that is orthogonal to the direction in which the coating slurry in the supply port or the supply pipe flows into the die head.

According to one embodiment, a system for manufacturing a fully impregnated thermoplastic prepreg includes a mechanism for moving a fabric or mat and a drying mechanism that removes residual moisture from at least one surface of the fabric or mat. The system also includes a resin application mechanism that applies a reactive resin to the fabric or mat and a press mechanism that presses the coated fabric or mat to ensure that the resin fully saturates the fabric or mat. The system further includes a curing oven through which the coated fabric or mat is moved to polymerize the resin and thereby form a thermoplastic polymer so that upon exiting the oven, the fabric or mat is fully impregnated with the thermoplastic polymer. During at least a portion of the process, humidity in the vicinity of the coated fabric or mat is maintained at substantially zero.

Methods and apparatuses herein provide for the application of viscous fluids, such as adhesives, in pre-determined patterns, to an advancing substrate. The fluid applicator comprises a slot die applicator and a substrate carrier. The slot die applicator comprises a plurality of applicator channels, each applicator channel being controlled by a switching valve, and wherein the switching valves are independently switchable.

The invention relates to an apparatus for the two-sided coating of at least one running flat material web (10),

with a first and a second coating nozzle (2, 3), wherein the first coating nozzle (2) is providable to the first side of the flat material web (10) and the second coating nozzle (3) is providable to the second side of the flat material web (10), in order to coat the respective side of the flat material web (10), and wherein at least one, preferably both, coating nozzles (2, 3) are transferable from a working position into a maintenance position (A, W) and back, as well as

with supply line sections (4, 8) with throughflow channels (4a, 8a) that are embodied therein and that are connected with one another in the working position (A) and that ensure a throughflow for supplying a hot, liquid coating material to the respective coating nozzle (2, 3), wherein, during the transferring of at least one of the said coating nozzles (2, 30) from the working position into the maintenance position (A, W), a first rigid supply line section and a second rigid supply line section (4, 8), which in the working position (A) enable a throughflow of the coating material to the coating nozzle (2, 3), are automatically moved relative to one another in such a manner so that the throughflow channels (4a, 8a) embodied in them are moved relative to one another in order to interrupt the throughflow of the coating material to this coating nozzle (2, 3).

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 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.
