A pre-cured laminate plate for use within a component of a wind turbine rotor blade may generally include a plate body extending in a thickness direction between a first side and a second side and in a widthwise direction between a first end and a second end. The plate body may define a plate thickness between the first and second sides. The pre-cured laminate plate may also include a plurality of channels formed in the plate body between the first and second ends. Each channel may extend in the thickness direction between a top end that is open along the first side of the plate body and a bottom end that terminates at a location between the first and second sides of the plate body such that the plate body defines a reduced thickness between the bottom end of each channel and the second side of the plate body.

A headliner includes a ceiling and an edge flange extending away from the ceiling. The edge flange has a backing section at a free end and a wall section connected to the ceiling. An edge fold is formed on the headliner by a method that includes heating the flange and folding the backing section over and parallel to the ceiling. The method also includes forming a reverse turned edge by folding the backing section over the wall section and compressing the backing section against the wall section.

The present disclosure provides method, computing device readable medium, and devices for dental appliances formed with folded material components. An example of a method of forming a dental appliance, includes forming a shell having a number of tooth apertures configured to receive and reposition a number of teeth of a patient along one jaw of a patient, the shell having a number of specialized components and wherein the number of specialized components are formed from folding multiple sections of the first sheet of material over each other.

A method for making a covering is described. The covering includes a first layer made of a flexible material; a second and a third layers made of a preferably rigid material engaged on opposite sides to the first layer. The second and the third layers respectively have a plurality of V-shaped grooves defining respective adjacent rigid and corresponding structural portions. Each rigid structural portion can be oriented with respect to the adjacent rigid structural portion, by folding the first layer so as to model the covering according to three-dimensional configurations and/or a simple or double curvature. The method is preferably performed through a virtual designing of the shape desired to be obtained and a processing of the same for the obtainment of the grooves required to attain such shape.

A duct pre-form configured for forming a section of curved duct is provided. The duct pre-form includes a layer of foam insulative material. The layer of foam insulative material has a first and second major side. A first facing layer is attached to the first major side of the foam insulative material. A second facing layer is attached to the second major side of the foam insulative material. A plurality of depressions is formed in one of the major sides of the layer of foam insulative material and one of the first or second facing layers. The plurality of depressions is formed without breaking, tearing, ripping or otherwise marring the continuity of the first or second facing layers.

A method and apparatus for forming a bend in composite panel. A method for forming a bend in a composite panel comprises forming a slot having a curved flange in the composite panel, inserting a sheet into the curved flange, and bending the composite panel with the slot and the sheet within the curved flange about a longitudinal axis of the slot to form the bend.

A fold-enhancing device includes a pressing member, at least one retaining member, and a moving mechanism. The pressing member presses against a fold line of a recording-medium bundle folded into a booklet shape. The recording-medium bundle is obtained by stacking multiple sheets of recording media. The retaining member retains the recording-medium bundle and is provided at a position located away from the fold line in a direction intersecting the fold line and not in contact with the pressing member. The moving mechanism moves the pressing member and the retaining member in a direction extending along the fold line.

A method of making a sandwich-type composite panel having a cellulose-based core and a living hinge from a stack of material is provided. The stack includes first and second reinforced thermoplastic skins, first and second sheets of thermoplastic adhesive and a cellulose-based cellular core disposed between the sheets and the skins. A pressure is applied to the stack after heating the stack wherein the skins are bonded to the core by the sheets to form the composite panel. A portion of the composite panel is crushed at a predetermined location simultaneously with applying the pressure to locally compact and separate the cellular core at the predetermined location to form two side portions of the panel. The heated first skin stretches during the step of crushing while remaining intact between the two side portions. The skins bond together at the predetermined location to form the living hinge.
