A double-sided coating device includes: a conveying mechanism for a base material that includes a first surface and a second surface; a first die that applies a first coating material onto the first surface; and a second die that applies a second coating material onto the second surface. The conveying mechanism includes: a roll that conveys the base material, in which the position at which the base material separates from the circumferential surface is higher than a target coating height of the base material; and a drawing section that draws the base material such as to bring the base material closer to the target coating height.

A paint baking oven bakes a wet coating film applied to a vehicle body while conveying the vehicle body. The vehicle body has a main shell body to which side doors are attached via hinges. The topcoat paint baking oven includes a oven body and a hot air supplier that supplies hot air into the oven body. The oven body is configured to include a first oven body and a second oven body. The first oven body has a side-to-side width corresponding to a body width of the vehicle body in a state of closing the side doors. The second oven body has a width wider than the side-to-side width of the first oven body. The width of the second oven body corresponds to a body width of the vehicle body in a state of opening the side doors.

A paint baking method includes a process for conveying a vehicle body while exposing the vehicle body to a hot air atmosphere to bake a wet coating film applied to the vehicle body. In the vehicle body, hinges and door offset members are attached between hinge fastening parts of the main shell body and hinge fastening parts of the side doors. The distance between the hinge fastening parts of the main shell body and the hinge fastening parts of the side door in a state in which the hinges and the door offset members are attached is longer than a distance between the hinge fastening parts of the main shell body and the hinge fastening parts of the side door in a finished vehicle state.

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.

A method is provided for coating a fibrous web, in particular a fibrous web comprising nanocellulose fibres. The method includes steps of applying a coating agent to a textured surface region of a textured substrate, applying a fibre furnish or a wet fibrous web onto the coated textured surface region of the textured substrate, optionally dewatering to provide a wet fibrous web, and drying said wet fibrous web such that at least a portion of said coating agent is transferred to said fibrous web. The method provides a coated fibrous web with improved barrier properties.

A substrate treatment method for treating a substrate, includes the steps of: (A) heating the substrate having a coating film formed on a surface thereof by supply of a coating solution; (B), after the (A) step, moving a discharge destination of a removing solution from a peripheral position on the surface of the substrate toward a center side of the substrate and turning it back at a first position to return it again to the peripheral position while rotating the substrate; (C), after the (B) step, moving the discharge destination of the removing solution from the peripheral position on the surface of the substrate toward center side of the substrate and turning it back at a second position closer to an outside than the first position to return it again to the peripheral position while rotating the substrate; and (D), after the (C) step, heating again the substrate.
