Abstract

PURPOSE:To improve the arraying accuracy of strands in a sheet widthwise direction by aligning many sheet strands on a base, alinging strands in a slot formed between the sheet strands thereon, and pressure deforming them. CONSTITUTION:Strands 27 are densely aligned between a pair of width restricting guides 26 on the upper surface of a base 25. Then, round strands 29 are then inserted into a slot 28 formed between the adjacent strangds 27. The strands 29 are accurately aligned in the positional accuracy of the strands 27 of lower different sectional shapes. The assembly of the strands 27, 29 is deformed by a roller 30, thereby obtaining a coil sheet 31 in which the strands 27, 29 are aligned without gap.

An embodiment of this invention is shown in FIG. First, base 25
Strand wires 27 are arranged closely between a pair of width regulating guides 26 on the upper surface (Fig. 8 (A+)). This wire 27 has an irregular cross section with both side surfaces parallel and the upper surface sloped in an inverted V shape. By arranging the strands 27 closely between the width regulating guides 26, it is possible to obtain a fine pi in the sheet width direction.
When such irregular cross-section strands 27 are used, since the same adjacent strands 27 touch on parallel sides, accuracy in the sheet width direction can be achieved even more reliably and easily. Next, a round wire 29 is inserted into the groove 28 formed between the adjacent wires 27 (FIG. 8(B)). The round strands 29 are aligned accurately in accordance with the positional accuracy of the irregular cross-section strands 27 below. lastly,
The collected leaves 9 of these strands 27 and 29 are pressurized with a loaf 30 as shown in FIG.
As shown in FIG. tDI, it is possible to obtain a coil sort 31 in which each of the strands 27 and 29 is in contact with each other without any gaps. The sheet strand 29, which was round, has been deformed into a pentagon, and the sheet 3 has a shape in which strands 27 and 29 having a pentagonal cross-section in an upside-down direction are arranged alternately.
It becomes 1. Pressure is applied by the roller 30 while applying static pressure or vibration. The strands 27 and 29 are continuously fed onto the base 25 and then pressed by rollers 30. Further, the wires 27 and 29 are provided with an insulating film having a bonding layer.

Although the sheets are manufactured continuously in this manner, the strands 35 and 36 are guided by the grooves 33a and 34a of the guide loaves 33 and 34, so the arrangement accuracy in the width direction of the sheet 40 is very high. Furthermore, since the wires 35 and 36 are bare copper wires, sufficient tension can be applied without worrying about damage to the coating. Also, since bare copper wire is used, the material cost is low.

[Claims] 111 A step of arranging a large number of sheet wires in close rows between a pair of width regulating guides on the upper surface of the base, and a step of arranging a large number of sheet wires in close rows on the upper surface of the arranged sheet wires between adjacent sheet wires on the upper surface of the arranged sheet wires. A process of arranging a large number of sheet strands in each of the formed grooves, and processing the sheet strands placed on the upper surface from above to form a diamond shape so that each sheet strand is in contact with each other without any gaps. (2) A method for manufacturing a coil sheet including the step of making a sheet for coils (2) A pair of coil sheets in which a large number of annular grooves into which a part of the sheet wires are fitted are provided at a pitch of every other sheet wire. a step of preparing a device in which guide rollers are arranged side by side with grooves and partition walls between the seven grooves facing each other; and a step of feeding a sheet wire to each groove of both guide loafs, and feeding one of the guide rollers. An insulating sheet having a fusion layer on both sides is fed between the sheet wire and the sheet tension wire of the other guide roller. A method for manufacturing a coil sheet, which includes the steps of: biting the sheet wire through the wire; and applying pressure from both sides of the sheet wire to smooth out unevenness of the sheet wire to produce a coil sheet. (3) The process of cutting a metal plate into two rows of sheet strands in a staggered arrangement by sandwiching the metal plate between a pair of loaves having a large number of grooves that engage with each other, and the process of cutting a metal plate into two rows of sheet strands arranged in a staggered manner, and a sheet strand having an insulating coating between each of the sheet strands in both rows. Manufacture of coil sheets, which includes the process of arranging the wires, and processing the collected sheet wires from both sides to form a rhombus shape so that each sheet element wire is in contact without any gaps to form a coil sheet. Method.
