    • PROBLEM TO BE SOLVED: To provide an optically detectable adhesive tape for exchanging a flying roll for a flat web material wrapped around the roll. SOLUTION: The adhesive tape for exchanging a flying roll for a flat web material wrapped around the roll includes: at least one substrate layer; and an adhesive layer. The adhesive tape is such that: at least a part of the substrate layer(s) turning toward the adhesive layer is optically detectable; or, a means enabling optical detection is provided in between the substrate layer(s) and the adhesive layer, wherein the adhesive layer is formed so as to enable the adhesive layer's optical detection to be attained through the adhesive layer. In this adhesive tape, the glossiness at the surface on the outside of the adhesive layer, namely, the quotient of the directive component to scattering reflective component among a light flux incident to the surface is adjusted so as to be reduced at 20% or more, compared with adhesive tapes whose structures are the same as this adhesive tape but are nonadjusted tape.

    • 要解决的问题:提供一种光学上可检测的胶带,用于更换卷绕在卷上的扁平卷材的飞轮。 解决方案:用于更换缠绕在辊周围的扁平网状材料的用于更换飞轮的胶带包括:至少一个基底层; 和粘合剂层。 粘合带是这样的:至少一部分转向粘合剂层的基底层是可光学检测的; 或者在基材层和粘合剂层之间设置能够进行光学检测的装置,其中形成粘合剂层,以便能够通过粘合剂层获得粘合剂层的光学检测。 在该粘合带中,粘合剂层外表面的光泽度,即入射到表面的光束中的指向成分与散射反射成分的折射率被调整为20%以上 ,与其结构与该胶带相同但不调整胶带的胶带相比。 版权所有(C)2011,JPO&INPIT
