(canceled) ### Claim 16 A bushing for producing fibers from molten mineral material, the bushing comprising a one-piece blank constructed of flat, foldable precious metal; wherein the one-piece blank comprises a baseplate, side walls, end walls, and flanges; and wherein the baseplate, the side walls, the end walls, and the flanges are articulated in one piece. ### Claim 17 (depends on 16) The bushing of claim 16, wherein neighbouring walls of the bushing are welded to one another. ### Claim 18 (depends on 17) The bushing according to claim 17, wherein portions of the blank that are neighbouring one another and that are connected by welding have the same thicknesses as one another at the location of the welds. ### Claim 19 (depends on 16) The bushing according to claim 16, wherein one of the side walls is connected to one of the neighbouring end walls of the one-piece blank by way of a corner part. ### Claim 20 (depends on 16) The bushing according to claim 16, wherein the side and end walls of the one-piece blank are only connected to one another by way of the baseplate. ### Claim 21 (depends on 16) The bushing according to claim 16, wherein the one-piece blank has different thicknesses in different regions thereof. ### Claim 22 (depends on 16) The bushing according to claim 16, further comprising a cover plate that is articulated in one piece with a flange and a side wall, wherein the cover plate is arranged between the side wall and the flange. ### Claim 23 (depends on 16) The bushing according to claim 16, wherein the precious metal is selected from the group consisting of PtAu5, PtIr1 , PtRh5, PtRh10, PtRh20, PtIr3, PtIr5, pure platinum and combinations thereof. ### Claim 24 (depends on 16) The bushing according to claim 16, wherein the precious metal is an oxide-dispersion-strengthened (ODS) precious metal. ### Claim 25 (depends on 24) The bushing according to claim 24, wherein the oxide-dispersion-strengthened (ODS) precious metal is strengthened by yttrium oxide and/or zirconium dioxide. ### Claim 26 (depends on 16) A method for producing the bushing of claim 16, comprising: creating a developed view of the bushing to be produced; producing a one-piece blank from a foldable flat material of precious metal that corresponds to the developed view of the bushing; and folding the one-piece blank to produce the bushing. ### Claim 27 (depends on 26) The method of claim 26, further comprising: removing material of the one piece blank in order to produce regions of different thickness; attaching beads to the one-piece blank; and welding together edges of a side wall, an end wall, or a flange that neighbour one another. ### Claim 28 A method for producing a bushing for producing fibers from molten mineral material, comprising: creating a developed view of a bushing to be produced; producing a plurality of blanks from a foldable flat material of precious metal that corresponds to the developed view of the bushing; and folding and connecting the plurality of blanks to produce the bushing. ### Claim 29 (depends on 28) The method of claim 28, further comprising: removing material from the plurality of blanks in order to produce regions of different thicknesses; attaching beads to the plurality of blanks; sealing the connection between the blanks by welding; welding together edges of a side wall, an end wall, or a flange that neighbour one another. ### Claim 30 (depends on 29) The method according to claim 29, further comprising attaching power feeds and/or supporting or reinforcing parts to the bushing. ### Claim 31 A one-piece blank of foldable, flat precious metal that corresponds to a developed view of a bushing and is suitable for producing a bushing, comprising areas for a baseplate, a side wall, and an end wall articulated in one piece on said baseplate and a flange respectively articulated in one piece on said side wall and end wall. ### Claim 32 A method for checking the position of welds in bushings for producing fibers from molten mineral material, comprising: creating a developed view of a bushing to be produced; producing one or more blanks from foldable flat material of precious metal that together correspond to the developed view of the bushing; folding and positively connecting the blanks; sealing the positive connection by welding; and welding together edges of side and end walls or flanges that neighbour one another, wherein the developed view of the bushing is devised in such a way that welds are located in sections of the bushing that are subjected to less loading.
