A method of making a metal reinforcing member that is to be mounted on a leading edge or a trailing edge of a composite blade of a turbine engine, the method including: shaping two metal sheets, positioning them on either side of a core including at least one recess that is to form a mold for a spacer for positioning the reinforcing member, assembling them together under a vacuum, conforming them against the core by hot isostatic compression, and cutting them to separate the reinforcing member and release the core.

A punch tool is provided that is adapted to create a pair of spaced apart apertures through a thin-walled work piece when clamped. The device comprises a hand tool having a pair of handles and a tool head comprising a first head portion and a second head portion. The head portions pivot away from each other and bear against one another based on movement of the handles to compress a sheet of material therebetween. The head portions are T-shaped members, in which the first head portion supports a pair of dies and the second head portion supports a pair of punches adapted to be received by the dies. The head portions are clamped together, whereby the dies are punched through the work piece sheet material to form spaced apart apertures. An embodiment of the head portions contemplates an adjustable width for varying the spacing of the punches.

An apparatus for manufacturing filters and inserting the filters into single dose capsules for preparing beverages comprises a punching and forming device for punching material portions from a sheet material and forming the material portions to assume the form of a beaker-shaped filters, an insertion device arranged in a distance of the punching and forming device along a work flow direction for inserting the formed filters into the capsules, a first transport device (175, 176) for accepting a plurality of formed filters from the punching and forming device and transporting the accepted filters to the insertion device, a second transport device (177) for accepting a plurality of formed filters from the punching and forming device and transporting the accepted filters to the insertion device. The first transport device (175, 176) and the second transport device (177) are movable with respect to each other.

There is provided a manufacturing apparatus and a manufacturing method for a stretch-formed product which can improve the yield of material in the stretch forming performed while clamping the blank by the lock beads. The manufacturing apparatus for a stretch-formed product includes a die and a blank holder which have clamping surfaces facing each other, a punch that, in a state where a margin of a blank of a sheet material is clamped by the clamping surfaces of the die and the blank holder, relatively presses a forming region of the blank into the die and thereby performs stretch forming on the forming region of the blank, and lock beads that are provided on the clamping surfaces of the die and the blank holder in mutually similar shapes and have first surfaces, second surfaces that intersect with the first surfaces, and third surfaces that intersect with the second surfaces from outer edges toward the centers of the die and the blank holder, the first surfaces each having a plurality of depression-protrusion parts.

The invention relates to a device and a method for producing at least partially closed hollow profiles from a sheet by a U-O-forming with a tool set having a U-punch in a first tool half for producing an at least partially U-shaped sheet and an upper die in a second tool half for forming an at least partially U-shaped sheet into an at least partially closed hollow profile. Parts of the tool set run parallel to one another in the axial direction of the at least partially closed hollow profile to be produced and are arranged above one another in the closing direction of the tool halves, wherein a common matrix receiver is provided between the tool halves of the tool set, which receiver comprises at least two identical, partially U-shaped dies for the tool set and can rotate about its axial axis.
