    • A closing tape prevents winding looseness of a roll photo film and a light-tight sheet which are wound around a spool. After an adhesive agent layer formed on one end of the closing tape is adhered to a surface of the light-tight sheet, an adhesive agent layer formed on the other end of the closing tape is adhered to a surface of the closing tape. The adhesive agent layer consists of multiple adhesive dots. The respective dots are formed by heat sensitive adhesive agent filled in the respective cells of a gravure roll to coat on the closing tape by gravure coating. Adhesive force is stabilized due to uniformity in size and thickness of the dots. Moreover, the cells are provided at same intervals and heat sensitive adhesive agent having optimum viscosity is used, so that the adjacent dots are prevented from connecting each other.
    • 闭合带防止卷绕在卷轴上的卷筒胶片和不透光片材的卷绕松动。 在封闭带的一端形成的粘合剂层粘附到不透光片的表面之后,形成在封闭带的另一端上的粘合剂层粘附到封闭带的表面上。 粘合剂层由多个粘合剂点组成。 相应的点由填充在凹版辊的各个单元中的热敏粘合剂形成,以通过凹版涂布涂覆在封闭带上。 由于点的尺寸和厚度的均匀性,粘合力被稳定。 此外,以相同的间隔设置电池,并且使用具有最佳粘度的热敏粘合剂,从而防止相邻的点彼此连接。

    • For producing an abrasive tape (11) including a film substrate (2) and a polishing abrasive layer (10) laminated on one surface of the film substrate (2) and having on the outer surface thereof a plurality of recessed parts (9), the film substrate (2) is wrapped partially around the outer peripheral surface of a roll formplate (1) having on the surface thereof a plurality of concavities (5), and, as the roll formplate (1) is rotated, the film substrate (2) is fed thereto. On one hand, an ionizing radiation curing type resin (3) is supplied into the interface between the roll formplate (1) and the film substrate (2) therearound to be formed by the said concavities (5), and the recessed parts (9) are formed on the resin surface. During this forming, radiation rays (R) are projected from an ionizing radiation ray source (8) toward the resin (3) thereby to cure the resin (3) and, at the same time, to render the resin (3) and the film substrate (2) into an integral structure. The abrasive tape (11) obtained in this manner is separated from the roll formplate (1). The abrasive tape (11) thus obtained is of high product quality. The production method is highly efficient and is suitable for mass production of abrasive tapes of identical concave-convex surface figuration.
