    • In order to manufacture a grinding tape (11) which consists of a film substrate (2) and a grinding layer (10) laminated on one surface thereof, and which has a plurality of recesses (9) in the surface of the grinding layer (10), a film substrate (2) is wound partially around the circumferential surface of a roll intaglio (1) provided with a plurality of recesses (5) in the surface thereof, and the film substrate (2) is fed as the roll intaglio (1) is rotated. In the meantime, an ionizing radiation setting resin (3) is fed between the roll intaglio (1) and the film substrate (2) passed therearound, in such a manner that the resin (3) is shaped by the recesses (5) to cause recesses (9) to be formed in the surface of the resin (3). During the shaping of the resin (3), the radiation R is applied from an ionizing radiation source (8) to the resin (3) so as to harden the resin (3) and combine the resin (3) and film substrate (2) with each other unitarily. A grinding tape (11) thus obtained is peeled off from the roll intaglio (1). This grinding tape (11) is of a high quality. The method of manufacturing such grinding tapes has a high efficiency, and is suitable for the mass-production of grinding tapes having the same recesses and projections on the surfaces thereof.
    • 为了制造由在其一个表面上层叠的膜基板(2)和研磨层(10)构成的研磨带(11),并且在研磨层的表面具有多个凹部(9) 如图10所示,在其表面设置有多个凹部(5)的辊凹版(1)的周面部分地卷绕薄膜基板(2),并且将薄膜基板(2)作为辊凹版 (1)旋转。 同时,将电离辐射固化树脂(3)以这样的方式供给到辊凹版(1)和其周围的薄膜基材(2)之间,使得树脂(3)通过凹部(5)成形为 导致在树脂(3)的表面中形成凹部(9)。 在树脂(3)成形期间,将辐射R从电离辐射源(8)施加到树脂(3),以使树脂(3)硬化并将树脂(3)和薄膜基底(2) )彼此一体。 将由此获得的研磨带(11)从辊凹版(1)剥离。 该研磨带(11)具有高质量。 制造这种研磨带的方法具有高效率,并且适用于批量生产其表面上具有相同凹凸的研磨带。
