PROBLEM TO BE SOLVED: To provide a one-sided and a double-sided tape effectively affording circular bonding. SOLUTION: A helical continuous circular pressure-sensitive adhesive tape is laminated from the core to prepare one continuous helical tape. In use, the tape is stripped, cut to a suitable length and used. Although the circular shape is a main purpose, a response to an optional circular arc shape can be made. Furthermore, even helical bonding can be carried out. COPYRIGHT: (C)2006,JPO&NCIPI
