20220072810 · 2022-03-10 · ·

A method of manufacturing cross-corrugated support structures is provided. A mold having a molding surface with a first plurality and a second plurality of corrugations therein is used to introduce corrugations into a flexible, carbonaceous sheet. Cross-corrugations are introduced into the sheet by placing the sheet onto the molding surface, encapsulating the sheet to form a vacuum chamber, and evacuating the vacuum chamber of air. As air is evacuated from the vacuum chamber, the sheet is drawn upon the molding surface causing the sheet to conform to the shape of the molding surface. Thermosetting resin is infused into the sheet and cured causing the sheet to rigidly retain the shape of the molding surface. The sheet is further reinforced by securing at least one support member to the sheet using thermosetting resin.

Method and device for producing a 3-D substrate coated with a laminate

A forming tool is used, which has a tool trough arranged in a stationary manner and a pressure bell, which can be lowered onto and lifted away from the tool trough. An arrangement is created in which a single- or multi-layer, initially flat, flexible laminate separates the trough interior from the pressure-bell interior in a pressure tight manner. A table, on which the 3-D substrate to be coated is located, assumes a lowered position within the trough interior; there is a considerable, free intermediate space (between the laminate and the 3-D substrate. A radiant-heater assembly is inserted into said intermediate space. The radiant-heater assembly has a carrier, on the top side of which radiant heaters that can be activated are attached and on the bottom side of which radiant heaters that can be activated are attached.

Die, manufacturing method therefor, and molded body manufacturing method

Fixtures and related system and methods are disclosed. In accordance with an implementation, a method includes applying a resin onto a substrate and positioning the substrate on over a chuck of a base of a fixture. The method also includes moving a mold into engagement with the resin and curing the resin. The method also includes detaching the mold and the resin and, while detaching the mold and the resin, determining a detachment force applied as a function of a distance of detachment between the mold and the resin.

Methods for producing through-fluid bonded nonwoven webs

A method of creating a soft and lofty continuous fiber nonwoven web is provided. The method includes providing a first molten polymer and a second, different molten polymer to a spinneret defining a plurality of orifices and flowing a fluid intermediate the spinneret and a moving porous member. The method includes using the fluid to draw the first and second molten polymer components, in a direction toward the moving porous member, through at least some of the plurality of orifices to form a plurality of individual continuous fiber strands. The method includes depositing the continuous fiber strands onto the moving porous member at a first location to produce an intermediate continuous fiber nonwoven web, and intermittently varying a vacuum force applied to the moving porous member and to the intermediate web downstream of the first location and without the addition of more continuous fibers and without any heat applied.
