PROBLEM TO BE SOLVED: To provide an apparatus for shaping a sheet material, by which: shaping rolls can be easily positioned and a large number of fine three-dimensional shapes can be rapidly and precisely formed on a sheet material.SOLUTION: A pair of shaping rolls (3, 4) that are parallel to each other include, on circumferential surfaces thereof, recessed and protruding shapes (6) that mesh with each other at a face-to-face position. The downstream-side shaping roll (4) includes, inside a roll main body (4a), air passages (28) that extend in a direction of a roll shaft core (27) and air vent holes that connect the air passages (28) to the circumferential surface. A communication member (30) is disposed adjacently to the end of the roll main body (4a) and includes: an air intake port that can communicate with the air passages (28) in a first preset region in a circumferential direction and an air supply port that can communicate with the air passages (28) in a second preset region. The air intake port is communicably connected to air intake means, and the air supply port is communicably connected to air supply means.COPYRIGHT: (C)2015,JPO&INPIT【課題】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、シート材賦形装置を提供する。【解決手段】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。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。【選択図】図4
