Claims18
1-15. (canceled)
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.
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.
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.
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.
