A method of making a laminated shingle is provided. The method includes coating a shingle mat with roofing asphalt to make an asphalt-coated sheet, adhering a reinforcement member to a portion of the asphalt-coated sheet, covering the asphalt-coated sheet, and optionally covering the reinforcement member, with granules to make a granule-covered sheet, dividing the granule-covered sheet into an overlay sheet and an underlay sheet, wherein the overlay sheet has a tab portion normally exposed on a roof and a headlap portion normally covered-up on a roof, the headlap portion having a lower zone adjacent the tab portion and an upper zone adjacent the lower zone, and wherein the reinforcement member is adhered to the lower zone of the headlap portion and laminating the overlay sheet and the underlay sheet to make the laminated shingle.

A filter sheet, a manufacturing method thereof and a display device are disclosed. The filter sheet includes: a first medium film, a second medium film and a third medium film attached to each other, wherein the filter sheet comprises a first pixel region, a second pixel region and a third pixel region; a portion of the first medium film in the first pixel region of the filter sheet is removed, a portion of the second medium film in the second pixel region of the filter sheet is removed, and a portion of the third medium film in the third pixel region of the filter sheet is removed; the first medium film reflects light in a first wavelength range and transmits light outside the first wavelength range; the second medium film reflects light in a second wavelength range and transmits light outside the second wavelength range; and the third medium film reflects light in a third wavelength range and transmits light outside the third wavelength range.

A system for out of autoclave bonded repairs which including a fixing structure (1) to the composite area to be repaired, including a frame (4) and fixing parts (5, 19) attached to the frame (4), a movable structure (2) able to be attached either to the fixing structure (1) or to the patch manufacturing table (3), which includes three shafts (6, 6, 6) and three engines (7, 7, 7) configured to be able to move the tooling support in the three axes X, Y and Z, and a tooling support of either scanning tool (9), milling tool (10), patch cutting tool (11) or composite patch handle tool (11), and a patch manufacturing structure (3).

A method of manufacturing a wind turbine blade shell part is described. Fibre mats and a root end insert are laid up in a mould part in a layup procedure by use of an automated layup system. The fibre mats are laid up by use of a buffer so that the fibre mats may continuously be laid up on the mould surface, also during a cutting procedure. The root end insert is prepared in advance and mounted on a mounting plate. The root end insert is lowered onto the mould by use of the mounting plate and a lowering mechanism. After the wind turbine blade shell has been moulded, the mounting plate is removed.

The present invention relates to a method for shaping a frame structure using a multilayer board to solve the technical problem of low production efficiency of the existing bamboo frame structure. The present invention has the first solution of bending a multilayer board into a profiled board using the board bending technology; cutting the profiled board into several framing units; and finally connecting end portions of one, two or plural framing units one another, thereby forming a frame structure. The present invention has the second solution of gluing and stacking a plurality of single boards and laminating them into a profiled board; cutting the profiled board into several framing units; and finally connecting end portions of one, two or plural framing units one another, thereby forming a frame structure.

The present invention relates to a method for manufacturing a bamboo framework body to solve the technical problem of low production efficiency of the existing bamboo framework body. The present invention has the first technical solution of bending a bamboo board into a U-shaped board, cutting the U-shaped board into several U-shaped units, and finally arranging a connecting rod at or close to an opening of the U-shaped unit to make into a bamboo framework body. The present invention has the second technical solution of gluing and stacking plural single bamboo boards and laminating them into a U-shaped board directly; cutting the U-shaped board into several U-shaped units; and finally arranging a connecting rod at or close to an opening of the U-shaped unit to make into a bamboo framework body.

A roll tensioner for use in maintaining a wrapping material cut edge of a wrapping material retained on a wrapping material roll located within a wrapping material box having an interior cavity with an interior front wall with a top cutting edge. The roll tensioner comprises a thin, flexible main body having distal and proximal end sections separated by a spring back reversion section, and formed having a first side and a second side. Attachment means, preferably an adhesive, is located on at least a portion of the proximal end section on the first side adapted to attach the proximal end section to the interior front wall of the wrapping material box. The spring back reversion section is composed of a material that has an immediate elastic response to a static load and is capable of substantially full recovery when the static load is removed. The distal end mechanically bends downward by way of the spring back reversion section in the interior cavity of the wrapping material box. The distal end section is adapted to rest against the wrapping material proximal to the wrapping material cut edge to retain the wrapping material cut edge in an upward, substantially parallel position to the interior front wall of the wrapping material box for easy grasping of the wrapping material cut edge by an end user.

The present invention relates to a composite container which has a bottom film layer and a top film layer at least partially adhered on its lower surface to the upper surface of the bottom film layer. The top film layer is scored to form at least one resealable flap and at least one pull tab continuous with the resealable flap, wherein the resealable flap is resealably adhered to the bottom film layer and the pull tab is not adhered to the bottom film layer. The bottom film layer comprises at least one cavity opening. A cardboard layer is adhered on its lower surface to the upper surface of the top film layer, wherein the cardboard layer has at least one cavity opening which is substantially aligned with the scoring of the top film layer resealable flap and the cardboard layer is perforated to form at least one pull tab which is substantially aligned with and adhered, on its underside, to the upper surface of the top film layer pull tab.
