A corrugated plastic box and a method for manufacturing a corrugated plastic box from a blank are provided. The method includes the steps of forming rounded edge seals on the perimeter edges of the blank, pre-sealing portions of the blank to form a plurality of areas in which major and minor flap slots and a glue tab are desired, ultrasonically scoring the blank to form a plurality of flap score lines, and cutting the blank through the plurality of pre-sealed flap slots and glue tab, leaving a sealed edge.

A composite component adapted to be formed into an aerofoil, a method of forming an aerofoil, an aerofoil, an aircraft wing and a forming jig. The method involves forming a flat layup sheet of plies (1) to be folded about a central leading edge region (6) of the layup into an aerofoil shape, applying to the flat layup (1) one or more layups of plies (9, 10) shaped as spars, partially curing the layup (1) with the spars attached, folding the resulting partially cured composite component (30) about the leading edge region (6) in a forming jig (19) so that opposing edges (4, 5) of the sheet meet as a trailing edge (36) of the aerofoil (35), clamping the jig (19) closed, and curing the composite component (30) and adhesive in the forming jig (19) to form the finished aerofoil (35).

The present disclosure provides a display motherboard and a method for manufacturing the same, a display substrate and a method for manufacturing the same, and a display device, and belongs to the field of display technology. In the method for manufacturing the display motherboard of the present disclosure, the display motherboard includes a plurality of display substrate areas each including a sub display area and a sub bending area; and the method for manufacturing the display motherboard includes: forming an adhesive force variable back film material having a first adhesive force on a flexible underlying substrate; removing the back film material in positions above the sub bending areas; and treating the remaining back film material to form a back film having a second adhesive force, wherein the second adhesive force is greater than the first adhesive force.

A method for fabricating a central caisson of an aircraft wing including a frame formed from U-section crossmembers. Formation of at least one crossmember includes forming a stack comprising at least one layer of resin film applied to a layer of dry fibers, pressing this stack to confer on it a U-section form and such as to compress the layers thereof, and pre-polymerization and/or polymerization of the resin of the stack. The manipulated fiber layers are layers of dry fibers, such that manipulation thereof by an automated machine may be effected for a reasonable cost and at a high throughput. Deposition of resin films carried by removable leaves, i.e., of which one of the faces is not adhesive, likewise facilitates manipulation by an automated installation.

The invention relates to a method for producing a folding core (50, 190, 300, 360, 370, 380) for a lightweight structure, wherein in a first method step bending lines (70, 170, 180) are applied onto a deformable flat semi-finished product (40).

The present invention relates to an apparatus and a method of folding a pouch case of a battery cell, and more particularly, to an apparatus and a method of folding a pouch case of a battery cell capable of preventing a meandering in a folding process and reducing non-uniformity of a folding amount by forming a pre-folding line on a pouch wing and folding the pouch wing on the basis of the pre-folding line.

The invention is directed to straight, consistent body scores on plastic corrugated boxes and a process for making the body scores.
