<p>The system has a roller apparatus which is provided with several rollers (10,20) for revolving around the rotating shafts (12,22). A support element twists around the vertical shaft (32) of the rollers, so that a structuring belt main surface (33) is engaged with structuring outer peripheral surface (13,23) of rollers. A belt (30) is provided with belt rib and belt groove. The belt rib, belt groove, roller rib and roller groove are extended in parallel with the vertical shaft of a belt, so that elastic deformation of belt is less than that of vertical shaft.</p> |
