A device for preparing a thermally conductive sheet with graphene fibers in an oriented arrangement includes a first mold and a second mold. The first mold is configured to press a first cuboid block, and the second mold is configured to repeatedly press the first cuboid block. The first mold is provided with a first mold groove. A first mold cover covers an opening end of the first mold groove, and the first mold cover and the first mold are configured to press the first cuboid block. A second mold groove is arranged on one side of the second mold, and a second mold cover is arranged at an opening end of the second mold groove. A movable thickness limiting block is arranged at a side of the second mold cover adjacent to the second mold groove, and is configured to be clamped in the second mold groove.

Disclosed herein is a molded laminated structure having negative draft angles and methods of manufacturing a molded laminated structure having negative draft angles. A preliminary structure having a first outer layer and a second outer layer is molded with a bend that divides the preliminary structure into two sections with an angle between the two sections of less than 180-degrees. Portions that extends from the sections are at positive draft angles. A groove is formed in the preliminary structure at the bend but not formed in a constant cross-section of the second outer layer. The preliminary structure is folding along the bend to at least partially close the groove and form a molded laminated structure with portions that extend at a negative draft configuration while retaining the second outer layer continuous throughout the molded laminated structure.

A pipe coupling for triple wall corrugated plastic pipe includes a triple wall corrugated bellmouth connector that is of a unitary construction with one end of the corrugated plastic pipe. This bellmouth connector is of higher strength and in cooperation with the two wall corrugated spigot provides a high strength coupling. This coupling includes the bellmouth connector and spigot that are made inline with the corrugated pipe. A method for the manufacture of the pipe includes controlling of an air pressure on the outside of a formed two wall corrugated pipe as an exterior third wall is secured thereto.

A sheet space-detecting device detects a space between a rear end of a preceding first fiber reinforced plastic sheet and a front end of a following second fiber reinforced plastic sheet in a conveyance path for fiber reinforced plastic sheets and includes: a light-detecting sensor that projects detection light on an area including the rear end of the first fiber reinforced plastic sheet, the front end of the second fiber reinforced plastic sheet, and a reference surface exposed from the space and receives reflected light thereof; and a spacer that supports the rear end of the first fiber reinforced plastic sheet and the front end of the second fiber reinforced plastic sheet in a state where the rear end and the front end are separated from the reference surface, in an area including at least a light-projected area on which the detection light is projected.

Material preparation devices and related methods include a material or substrate assembly and an application assembly for applying a fiber material.

Interlaminar features of a composite structure are laid up by placing and steering individual chopped fiber pre-preg segments onto a substrate.

This invention relates to application of labels from a supply of labels which are defined in sheet material and in which adjacent labels are joined together by a line of weakening to form a continuous label supply. The label sheet material is provided with a layer of adhesive which contacts with a backing layer to form the label supply. The leading label is provided with a leading edge portion detached from the backing layer from application at an application point to an article and the article and label feed movement are controlled such that the remainder of the label can be detached from the backing layer, and the line of weakening broken effectively and accurately and without the need for the sheet material of the label supply and/or backing layer to have a thickness to provide the level of rigidity or stiffness of the material which is conventionally required, thereby reducing material usage and wastage.

A composite article assembly arrangement includes mechanized assembly station tooling for supporting certain composite article assembly methodologies with a view toward a preferred lid assembly application. First assembly station tooling includes a stationary main base plate, opposed intermediate compactor plates, and opposed outer plates, which compactor plates and outer plates are movable relative to the stationary main base plate. One or more continuous webs bearing thermoformed first and second workpieces are directed through the mechanized assembly station tooling, which operates to both separate the first and second workpieces from the web(s) as directed therethrough and assemble the first and second workpieces in one clapping movement of the compactor plates and outer plates relative to the main base plate. Alternative assembly station tooling operates to direct first composite elements into assembled relation with stationary second composite elements for forming basic composites to which successive composite elements are similarly added.
