A wave winding device having a feed device and a winding device. The wave winding device has a wire entrainment device, which grasps a winding or a plurality of windings situated on the shaping core and entrains it or them in the transport direction. The wire entrainment device has a plurality of loose transport jaw members, each of which has a plurality of wire receiving grooves, a transport jaw placing device, which is situated in the area of the shaping core and places transport jaw members on the winding wire situated on the shaping core, and a transport jaw receiving device, which receives transport jaw members. The wire entrainment device further has a transport jaw entrainment device, which engages with the transport jaw members and moves these in transport direction.

A winding apparatus 23 forms a rectangle-tubular edgewise coil 1 by alternately repeating bending of a rectangular conductor 2 in a clockwise direction in a plan view in an edgewise manner and feeding of the rectangular conductor 2. The winding apparatus 23 includes a bending jig 31 configured to bend the rectangular conductor 2, five sway-prevention guides 50 arranged at regular intervals on the same circumference to prevent the edgewise coil 1 from losing its shape, the five sway-prevention guides 50 being configured so that when the rectangular conductor 2 is bent in the edgewise manner, the edgewise coil 1 is sandwiched between two adjacent ones of the five sway-prevention guides 50 in the clockwise direction, and a guide holding member 51 configured to be rotationally driven in synchronization with the bending of the rectangular conductor 2 in the edgewise manner and the feeding of the rectangular conductor 2.

The invention relates to a device and a corresponding method for manufacturing brush seals with obliquely positioned bristles. The method comprises the following steps: As the first step, a metal filament or wire (50) comprising a material for bristles is wound over two wire cores (42, 46) disposed at a distance from and running parallel to one another, to form a tightly packed metal filament or wire package (48). As the next step, the metal filament or wire package (48) is fastened to at least one wire core (42, 46). Then the region around at least one of the two wire cores (42, 46) is locally heated. Subsequently, at least one of the two wire cores (42, 46) is displaced.

The present invention is an embolization coil having an optimum morphological stability. The embolization coil includes a wire material made of an AuPt alloy. The wire material constituting the embolization coil has such a composition that a Pt concentration is 24 mass % or more and less than 34 mass %, with the balance being Au. The wire material has such a material structure that a Pt-rich phase of an AuPt alloy having a Pt concentration of 1.2 to 3.8 times a Pt concentration of an phase is distributed in an phase matrix. The wire material has a bulk susceptibility of 13 ppm or more and 5 ppm or less. In a material structure of a transverse cross-section of the wire material, an average value of two or more average crystal particle diameters measured by a linear intercept method is 0.20 m or more and 0.35 m or less.
