However, when the folded portion is a wedge shaped corner portion, there arises a problem that the release film is easily broken as described above.

  • the guide surface 231 of the guide member 230 is electrically grounded via the guide member 230, the support member (not shown), and the stage 50.
  • a lead wire for grounding may be connected to the guide surface 231 or the guide member 230 to directly ground the guide member.
  • the film member may be a protective film used for a liquid crystal panel, or may be an electromagnetic wave shielding film used for an electronic device.
  • the to-be-adhered member was used as the glass substrate used for a liquid crystal panel, this invention is not limited to this.
  • it may be a synthetic resin substrate (including a synthetic resin film) used for a liquid crystal panel.
  • it may be a glass substrate or a synthetic resin substrate (including a synthetic resin film) used for other than the liquid crystal panel (for example, an organic EL panel or other display).
  • the electronic circuit board used for things other than a display may be used.
  • Toshikal (registered trademark) S coating processing As a process for applying conductive non-adhesive surface processing to the guide surface 231 of the guide member 230, a technology for surface processing called "Toshikal (registered trademark) S coating processing" To adopt such a coating process, Toshikal (registered trademark) S, UNA-300 series (UNA-310-X10), UNA-800 series, TS-1000 series, TS-1080 series, TS-1310 series Although it is possible to preferably use ones, the present invention is not limited thereto.
  • the film thickness of the coating film of Toshikal (registered trademark) S is, for example, preferably 1 ⁇ m to 200 ⁇ m, and preferably 3 ⁇ m to 150 ⁇ m, but the present invention is not limited to this.
  • a concavo-convex structure may be formed on the guide surface 231 of the guide member 230.
  • the average surface roughness of the concavo-convex structure in this case is preferably 2 ⁇ m to 15 ⁇ m, but the present invention is not limited to this.
  • the affixing / peeling synchronization mechanism section 221 actively synchronizes with the affixing operation of the polarizing film 30 to perform the peeling operation of the release film
  • the affixing / peeling synchronization mechanism Although the clamper 221c is provided in the part 221 and the release film 40 is clamped by the clamper 221c, the clamper 226 of the feeder 225 is only used for the indexing operation of the polarizing film 30 without providing the clamper 221c. Instead, it is also possible to use for paste / peel synchronization operation in the paste / peel synchronization mechanism unit 221.
  • the release film 40 is clamped by the clamper 226 of the feeder 225 when performing the sticking / peeling synchronization operation. Even in this case, the release film 40 is released from the tension by the dancer roll 222 as a tension applying unit, and the tension applied to the release film 40 can be reduced.
