Japanese Unexamined Patent Publication No. 229 discloses a suspending member having a thick-walled tubular portion in which a pseudo leather grain is formed and a fin portion which is adhered by utilizing the adhesiveness of a resin without using an adhesive. Since this hanging member is a single plate-shaped hanging member in which the fin portion is extruded integrally with the tubular portion by an extruder, the fin portion is used for seats of automobiles, beds, chairs, etc. In the case where a seam is sewn through the seam and a clip is locked to the tubular portion, when a person sitting on the seat moves his waist, the seat is deformed by the complicated external force of tension and pressure as the seat moves. However, because the fins of the bead are wide and thick, they cannot follow the deformation of the seat, and wrinkles, sags, and misalignment occur at the seam between the seat and the bead, causing slack and wrinkles on the surface of the seat. Is easy to make. Further, since the conventional bead has a high hardness, when it is used for a seat of an automobile or the like, it has a feeling of foreign matter when sitting on it.

る。According to the present invention, a long net having warp and weft fibers made of a thermoplastic synthetic resin fiber, for example, polyvinyl alcohol-based synthetic fiber and having a gap between lengthwise and widthwise yarns has a required width in the longitudinal direction. Then, one or more sets of heat cutting blades are fused and formed into a plurality of fin-shaped nets. Anchors are formed on the melted sides of the melted fin-shaped net. Since one or more mouthpieces of the extruder are formed in the female mold of the bead, the fin-shaped net is inserted into this female mold to form the mesh of the anchor of the net and the fin-shaped net near the anchor (gap). The thermoplastic resin (polypropylene resin) that has been melted by heating and discharged from the die is penetrated through the portion of, and cooled and fixed. One or more thermal cutting blades and nozzles can be provided.

３が得られることとなる。Embodiments of the present invention will be described with reference to the drawings. In the drawing, 1 is a warp fiber of the net A, 2 is a weft fiber of the net A, and is composed of several thermoplastic synthetic fibers, and there is a gap 10 between the warp fiber 1 and the weft fiber 2 to roughen it. The woven net 3 is formed. The surface of the net 3 is coated with a thermoplastic resin 4, and the size of the net 3 is, for example, 60 width.
It has a length of 500 mm and a length of 500 m, and is rolled up.
Since the width of the net 3 is 60 mm, if the width of each of the fin-shaped portions 5 and 6 of the bead is set to 30 mm, two net suspension members can be obtained from one roll-winding net having a width of 60 mm. If the net is wider than 60 mm in width, the number of heating cutting blades 10 is increased to obtain two or more nets 3.

To cut the net wound into a roll into two fin-shaped parts 5 and 6, a heating cutting blade 11 is arranged at the center of the net 3, and the end of the net 3 is sandwiched between the rolls. Pull out in the longitudinal direction. Therefore, an anchor portion (spherical lump) 7 (see FIG. 6) is formed on the end face portion of the longitudinal fiber 1 or the transverse fiber 2 that is in contact with the heating cutting blade 11.

る。As described above, according to the present invention, since the fin-like portion is formed of the braided net, the fin-like portion is vertically, horizontally and
Even if external force in the oblique direction or external force in the twisting direction or other combined external force is applied, the fin-shaped portion is highly flexible, so that when the bead of the present invention is sewn on the seam of the sheet, the external force is applied to the sheet, When the seat is used for a seat, there is no discomfort because the fins adapt to the external force even if the seams of the seat are subjected to a force in the irregular direction and the seams are to be released. Further, since the ball-shaped portion at the tip of the fin-shaped portion is locked to the bead formed by the extruder, there is an effect that the connected state between the fin-shaped portion and the bead is reliably maintained.
