The rotary body is configured to rotate around a rotation axis while interposing a sheet-shaped fiber, and cause, by frictional force generated between the rotary body and the sheet-shaped fiber, force to act on the sheet-shaped fiber while feeding the sheet-shaped fiber in a feed direction to vary a width and an orientation angle of the sheet-shaped fiber. The sheet-shaped fiber is impregnated with a resin or is before the impregnation with the resin. The rotation axis is parallel to a thickness direction of the sheet-shaped fiber. The force contains a component that is in a direction perpendicular to the thickness direction and to the feed direction.Type: ApplicationFiled: January 7, 2019Publication date: September 19, 2019Inventors: Daisuke HIRABAYASHI, Tamotsu Osada

Publication number: 20190283347Abstract: A method for manufacturing a rotor blade root assembly includes placing outer skin layer(s) onto a blade mold and arranging a root plate with a plurality of through holes adjacent to an end face of the blade mold. The method also includes placing a plurality of root inserts atop the outer skin layer(s) and abutting against the root plate, with each of the root inserts defining a fastener hole. The method also includes inserting a root fastener into each of the aligned through holes and longitudinal fastener holes. Moreover, the method includes placing inner skin layer(s) atop the root inserts. Further, the root plate may include at least one fluid hole configured therethrough to provide a non-gas tight root plate. Alternatively, at least one seal may be arranged between the root plate and the blade mold that forms a non-gas tight connection with either or both of the root plate or the blade mold during a vacuum infusion process.Type: ApplicationFiled: March 16, 2018Publication date: September 19, 2019Inventors: Alan M.

Publication number: 20190283348Abstract: A system and method of producing, large, very thin veneer patterns that can be used to decorate furniture such as table tops, flooring and interior decor or any other flat surface that show a plurality of wood end grain patterns. The process includes cutting a plurality of various diameter pieces of wood such as branches to expose the end grain. The pieces are then arranged in a holder with each piece sticking upward so that looking down, the end grain on each piece can be seen. The holder is then filled with a clear or pigmented resin and allowed to set. The hard resin slab is then removed and sawed in to very thin slices. Each thin slice is a desired veneer that can then be further glued onto a table top or the like. Symmetry patterns can be created by arranging veneers from subsequent layers side-by-side in various configurations.Type: ApplicationFiled: February 21, 2019Publication date: September 19, 2019Inventors: Djivan Schapira, Antoine Schapira
