, a groove 3 having the same width as the wire bundle 2 and shallower than the wire diameter of the brush wire l.
Each rung portion 7 of a ladder-shaped strip base material 6 is wound around an upper roll electrode 4 having a flat outer peripheral surface and fed in the same direction onto a lower roll electrode 5 having a flat outer peripheral surface.
Seam welding is performed by applying pressure and electricity to both the upper and lower roll electrodes 4.5.

For this reason, the temperature of the brush wires 1 on both the left and right sides of the wire bundle 2 is lower than that of the brush wire I in the center, and the welding area of each brush wire 1 to the arm portion 7 is as shown in FIG. The welding strength of the brush wire 1 was unstable.

In a method for manufacturing a multi-wire bundle sliding brush material that is seam-welded to each arm portion, strands with poor weldability having the same diameter or a somewhat larger diameter as the brush wire are arranged at both left and right outer ends of the wire bundle, The present invention is characterized in that a wire bundle together with the strands is seam-welded to each leg of the band-shaped base material, and then the strands are peeled off from each leg.

作業性が良い。(Function) As described above, in the method for manufacturing a multi-wire bundle sliding brush material of the present invention, wires with poor weldability having the same diameter or a somewhat larger diameter as the brush wire are arranged at both left and right outer ends of the wire bundle, and Since the wire bundle together with the strands is seam-welded to each edge of the band-shaped base material, the heat generated by the brush wire on both the left and right sides due to seam welding is inhibited by the heat generated by the strands, and the heat is dissipated from both sides of the band-shaped base material. Therefore, the brush wires on both the left and right sides will have the same temperature as the brush wire in the center, and the welding strength will be between the paths, etc., and the welding strength of each brush wire in the wire bundle will be stable. After seam welding the wire bundle, it is easy to peel off the wires with poor weldability from each leg, and they can be peeled off while being wound into a roll.
Good workability.

間でシーム溶接して多線束摺動ブラシ素材９を得た。(Example) An example of the method for manufacturing the multi-wire bundle sliding brush material of the present invention will be described. As shown in FIG.
μm Ag40%-Pd40%-Cu19.5%-Pt
Width 1.6m made by aligning and converging brush lines 1 made of 0.5%
A wire bundle 2 having a diameter of 1.m is formed into a wire bundle 2 having a width 1 having a flat rectangular groove 3 of 40 μm on the outer peripheral surface, which is the same width as the wire bundle 2 and shallower than the wire diameter of the brush wire l.
It was wound around an upper roll electrode 4 made of CrO34%Cu with a diameter of 2 mm and an outer diameter of 120 mm at a feeding speed of 1000 mm/m.
CrO, 4%-
A width of 11 mm was fed onto the lower roll electrode 5 made of Cu.
, a length of 4 mm and a width of 0.2 mm are provided at intervals of 2.5 mm in the longitudinal direction of a band-shaped base material 6 made of phosphor bronze with a thickness of 0.2 mm.
In seam welding each 6 mm length part 7 by pressurizing and energizing the upper and lower roll electrodes 4.5, wires with poor weldability of the same diameter as the brush wire 1, in this example, are attached to both left and right ends of the wire bundle 2. Be
The -Cu wires 8 are arranged, and the wire bundle 2 together with the Be-Cu wires 8 is attached to the upper and lower roll electrodes 4.
A multi-wire bundle sliding brush material 9 was obtained by seam welding between the parts.

とにおけるブラシ線ｌの１本当りの引張り強さを測定し
た処、下記の表に示すような結果を た。The multi-wire bundle sliding brush material 9 of this example has the same dimensions as the example in which wires with poor weldability are not arranged at both left and right ends,
A conventional multi-wire bundle as shown in FIG. 2 was obtained by seam welding the wire bundle 2 made of the same material to each of the straps 7 of the strip-shaped base material 6 of the same size and material as in the embodiment between the upper and lower roll electrodes 4.5. When we measured the tensile strength of each brush wire 1 with the dynamic brush material, we obtained the results shown in the table below.
・※試料数は２１本ＸＩＯケ＝２１θ本である。・*The number of samples is 21 XIO pieces = 21θ pieces.
上記の表で明らかなように従来例の多線束摺動ブラシ素
材は、ブラシ線１本当りの引張り強さのばらつきが大き
いのに対し、実施例の多線束摺動ブラシ素材はブラシ線
１本当りの引張り強さのばらつきが小さいことが判る。As is clear from the table above, the conventional multi-wire bundle sliding brush material has large variations in tensile strength per brush wire, whereas the multi-wire bundle sliding brush material of the embodiment has only one brush wire. It can be seen that the variation in tensile strength per hit is small.

良い。In the above embodiment, wires (Be-Cu wires) with poor weldability and having the same diameter as the brush wire 1 were arranged at both left and right ends of the wire bundle 2, but wires with a somewhat larger diameter than the brush wire 1 were arranged. Arranging the wires generates more heat in the strands, so it has the effect of preventing the heat of the brush wires l on the left and right ends from escaping to both sides of the strip-shaped base material.Also, the strands are limited to Be-Cu wires. It may be a SUS wire, or it may be a metal different from the brush wire to be welded and a material with different welding conditions, for example, a high melting point material such as W or Mo.

It is possible to obtain a stable multi-wire bundle sliding brush material with substantially uniform strength and small variation in the tensile strength of the brush wires.
