摘要： PURPOSE:To facilitate the manufacturing of a fiber suitable for the manufacturing of a conductive material, such as an electromagnetic wave shield material by using a primary metal layer of higher melting point than the temperature of heat treatment at the time of manufacturing the conductive material, and a secondary metal layer of lower melting point, both of which are connected in an integrated form, as a material plate. CONSTITUTION:A material plate 7 wound around a winding part 5 of a rotating shaft 4 is formed out of a primary metal layer 7a of higher melting point than the temperature of heat treatment at the time of manufacturing a conductive material, and of secondary metal layer 7b of lower melting point. When a blade board 9 is moved along a guide rail 10 in a direction of the material plate 7, at a constant speed, a fiber is continuously manufactured as a cutting blade 8 is fed. Since each metal layer 7a, 7b of the material plate 7 can be cut in a condition that the connected state is maintained, without the peeling off of each layer, a fiber suitable for manufacturing a conductive material in which a primary metal part and a secondary metal part are provided in an integrated form, can be manufactured. Also, since the connection is reinforced by mutually bridging the primary metal part of the fiber dispersed in the material by the melted secondary metal part, conductive function is remarkably improved.

摘要： PURPOSE:To facilitate the manufacture of a molding raw material in which the metallic fiber is distributed almost uniformly under a close contact condition in a resin material by heating a mixed fiber bundle wherein the metallic fiber and resin fiber are mixed to such a temperature as the resin fiber can be softened. CONSTITUTION:In a metallic plate 20 which is first wound around a rotating shaft 10, its end is cut by a cutting edge 51 together with a resin material 21 to generate a mixed fiber bundle KS consisting of metallic fiber and resin fiber continuously by cutting. Next, the mixed fiber bundle KS is heated to such a temperature as resin material 21 can be softened by an infrared heater 72, so that metallic fiber is bonded by the softened resin material 21. It is, thus possible to manufacture the molding raw material SS containing desired metallic fiber.

摘要： PURPOSE:To prevent entanglement or fusion of a metallic fiber, in manufacture of a metallic fiber through winding a metal plate around a rotation axis and cutting its end surface, by winding the metal plate with a separating member included and by cutting the plate together with the separating member. CONSTITUTION:A metal plate 20 is in the shape of a thin band, and a separating member 21 is made of wood free Japanese paper with the width same as the metal plate 20. The metal plate 20 is laid on the separating member 21, and the end part is inserted into a groove 11a of a rotation axis 10 and bent. They are wound in a large number of times with the separating member 21 under the other, and when the diameter reaches a predetermined size, the metal plate 20 is cut with the separating member 21, and the end part is stopped. In cutting, the rotation body 10 is rotated in the direction opposite to the winding of the metal plate 20, a tool slide 50 is advanced in the axial direction of the rotation axis 10 at a constant speed, and a cutter line 51a of a cutter 51 is brought into contact with an end surface 20a of the metal plate 20. By this, the end surface 20a of the metal plate 20 is cut with the separating member and a fine metallic fiber is manufactured. At the time, the metal plate 20 is in the non-adherence state due to inclusion of the separating member 21 and entanglement of fibers does not occur.

摘要： PURPOSE:To easily manufacture a porous body at low cost in a short time by cutting end face of a laminated body of plural strip-like materials having different m. p. and heating this after pressurizing the obtd. long fiber mixed body to melt and remove the fiber having lower m. p. CONSTITUTION:The two or more kinds of strip-like materials having different m. p. composed of metal or non-metal are laminated and rolled to obtain the laminated plate. The one end part of. this laminated plate is wound at plural times toward clockwise to winding part 11 of main shaft 10 having engaging groove 11a and the other end part thereof is stuck to the surface by welding to form a coiling material 20. Successively, while rotating the above main shaft 10 toward counterclockwise as the arrow mark as centering the axis 10a, a cutting tool 51 on a tool slide 50 is advanced to the coiling material 20 direction as the arrow mark and the cutting line 51a is abutted on the end face 20a of the coiling material 20 to cut there. After collecting the fiber mixed bodies mixing two or more kinds of the long fibers obtd. with this, the pressure is applied and density of the fibers is increased to obtain the fiber bundled body. After that, this fiber bundled body is sintered at higher temp. than the m.p. of the material having lower m. p. By this method, the fiber having lower m. p. is melted and removed to obtain the porous body.

In this case, a sheet composed of a lateral orientation long fiber layer 1' formed of stainless steel long fiber 2 whose fiber axis orients laterally and a longitudinal orientation long fiber layer 2' composed of a stainless steel long fiber 2 whose fiber axis orients longitudinally is used as the fiber member. The sheet is formed so as to unitedly sew the two layers 1', 2' by piercing a needle into overlapped long fiber layers 1', 2' at fixed spaces for extruding the bent fiber 3 of the stainless steel fiber 1 outside the stainless steel fiber 2.
