    • The mold-in fastening member, that can be molded into a resin article, of the present invention comprises (a) a substrate having a front surface and a back surface; (b) a plurality of engaging elements provided on the front surface; (c) a plurality of anchoring elements provided on the back surface, the anchoring elements being embedded into the resin article to fix the mold-in fastening member thereto; (d) a ferrite-containing layer formed on the front surface; (e) marginal portions continuously extending along respective lengthwise edges of the substrate; and (f) grooves formed on the substrate, which extend along the respective marginal portions to render the marginal portions easily bending relative to the substrate. The fastening member is easily placed in position on shoulders of a recess formed on a mold and protects the engaging elements from being buried or contaminated by a foaming resin because the ingress of the foaming resin into the recess is effectively prevented due to the close contact of the marginal portions with the shoulders. The fastening member of the present invention is small in size and improve the productivity, safety and working efficiency of the production of molded resin articles having mold-in fastening members.
    • 本发明的可模制成树脂制品的模制紧固件包括(a)具有前表面和后表面的基底; (b)设置在前表面上的多个接合元件; (c)设置在所述后表面上的多个锚定元件,所述锚定元件嵌入所述树脂制品中以将所述模制的紧固构件固定在其上; (d)在前表面上形成的含铁素体的层; (e)沿衬底的相应纵向边缘连续延伸的边缘部分; 和(f)形成在基底上的槽,其沿着相应的边缘部分延伸以使得边缘部分相对于基底容易弯曲。 紧固构件容易地放置在形成在模具上的凹部的肩部上,并且保护接合元件不被发泡树脂掩埋或污染,因为由于密封接触而有效地防止了发泡树脂进入凹部 边缘部分与肩膀。 本发明的紧固构件的尺寸小,并且提高了具有模制紧固构件的模制树脂制品的生产率,安全性和工作效率。

    • Provided is a pneumatic tire manufacturing method capable of improving the productivity of pneumatic tires each having surface fasteners in its tire inner surface, and of avoiding manufacturing a pneumatic tire having a deteriorated uniformity, as well as of preventing engagement elements of each surface fastener from being crushed. Also, provided is a pneumatic tire manufactured by the pneumatic tire manufacturing method. The pneumatic tire manufacturing method according to the present invention includes the steps of, in making a green tire having two-side fasteners in its tire inner surface in its tire circumferential direction, each two-side fastener including an engagement element group on both sides: covering the engagement element groups on first sides of the two-side fasteners with a protective rubber layer made of an uncured rubber; making a cylindrical first formed body on a making drum, with the two-side fasteners covered with the protective rubber layer being intermittently attached to an inner circumferential surface of the first forming body in a circumferential direction thereof with the engagement element groups on second sides of the two-side fasteners being interposed in between; bonding the first formed body to an inner circumference of an annular second formed body by compression through expanding the first formed body into a toroidal shape, and thereby making the green tire; and curing the green tire inside a mold of a curing machine while pressing the green tire from its inside by a bladder.
    • 本发明提供一种充气轮胎的制造方法,其能够提高在轮胎内表面具有表面紧固件的充气轮胎的生产率,并且避免制造具有劣化的均匀性的充气轮胎,以及防止每个表面紧固件的接合元件 碎。 此外,提供了一种通过充气轮胎制造方法制造的充气轮胎。 根据本发明的充气轮胎制造方法包括以下步骤:在轮胎内周面上形成具有两侧紧固件的生胎,其两侧紧固件包括接合元件组, 用由未固化橡胶制成的保护橡胶层覆盖两侧紧固件的第一侧上的接合元件组; 在制造滚筒上形成圆柱形的第一成形体,其中覆盖有保护橡胶层的两侧紧固件在其周向上间断地附接到第一成形体的内周表面,其中接合元件组在第二侧上 两侧紧固件插在其间; 通过将第一成形体膨胀成环状,通过压缩将第一成形体接合到环状的第二成形体的内周,从而制造生胎; 并在固化机的模具内固化生轮胎,同时通过气囊从其内部挤压生轮胎。
