Abstract
The invention relates to positioning of shaping rolls and makes it possible the rapid formation of a large number of fine three-dimensional shapes on a sheet material. A pair of shaping rolls that are parallel to each other include, on circumferential surfaces thereof, recessed and protruding shapes that mesh with each other at a face-to-face position. Rotating shafts of the pair of shaping rolls are cooperatively coupled with a rotational driving means through eccentric couplings. A downstream shaping roll includes, inside a roll main body, air passages that extend in a direction of a roll shaft center and air vent holes that connect the air passages to the circumferential surface. A communication member is disposed adjacent to the end of the roll main body and includes an air intake port that can communicate with the air passages in a first preset region in a circumferential direction, and an air supply port that can communicate with the air passages in a second preset region. The air intake port is communicably connected to an air intake means, and the air supply port is communicably connected to an air supply means.
