PURPOSE:To relatively easily correspond to proper wrinkle removal relating to various conditions of generating wrinkle and flare of an introduced web sheet material by integrally providing a streak or a plurality of streaks of pressure sensitive adhesive material along a roller rotational center line direction of a roller peripheral surface. CONSTITUTION:In a wrinkle removing guide roller, a streak or a plurality of streaks of pressure sensitive adhesive materials 3 are integrally provided along a roller rotational center line direction of a roller peripheral surface 2. As a result, in each turn of a web sheet material introduced to be fed at rotation and at a rotational speed, feed tension of the sheet material is temporarily increased, and the sheet material of applying the increased tension is separated from the pressure sensitive adhesive material 3. Consequently, continuity of a wrinkle and flare generated in the fed sheet material is eliminated by continuous tension increase by a prescribed period in each turn of the roller 1, and a sheet wrinkle in the case of introducing between press rolls in a sheet processing work can be prevented from being produced. |
