is easy to adjust the position of the shaping roll, yet many of the fine to the sheet material the stereoscopic shape I want to be able to and precisely formed at high speed. Mutually parallel pair of shaping rolls (3, 4) are provided with mutually meshing uneven shape at the face position (6) on the roll periphery. Axis of rotation of the shaping rolls (3, 4) (24) is operatively connected to a rotary drive means (10) through a shaft center difference joint (25). Downstream shaping rolls (4) is in the roll body (4a), long air path to the roll axis (27) direction (28), and a vent hole for communicating the ventilation path (28) in the roll peripheral surface provided. Communication member (30) is adjacent to the end of the roll body (4a) I will be arranged. Communication member (30), the first setting range of the circumferential air passage (28) provided with communication possible air inlet comprises air passage to a second set range (28) the communication possible air supply port. The intake port communicatively connected to the intake means, communicated and connected the air supply port to the air means.賦形ロールの位置調整が容易であり、しかもシート材に多数の細かな立体形状を高速で且つ精緻に形成できるようにする。互いに平行な一対の賦形ロール(3・4)は、対面位置で互いに噛み合う凹凸形状(6)をロール周面に備える。賦形ロール(3・4)の回転軸(24)は、軸心違い継手(25)を介して回転駆動手段(10)に連動連結する。下流側賦形ロール(4)は、ロール本体(4a)内に、ロール軸心(27)方向に長い通気路(28)と、通気路(28)をロール周面に連通する通気孔とを備える。連通部材(30)をロール本体(4a)の端部に隣接させて配置する。連通部材(30)は、周方向の第1設定範囲に通気路(28)と連通可能な吸気口を備え、第2設定範囲に通気路(28)と連通可能な送気口を備える。吸気口を吸気手段に連通連結し、送気口を送気手段に連通連結する。
