Laminating device

A laminating device adapted to laminate a plurality of sheet members on a lamination stage, comprising:

• a plurality of laminating heads that each has a curved holding surface for holding the sheet member;
• a drum section in which the plurality of laminating heads are arranged in a circumferential direction, the drum section holding each laminating head such that the curved holding surface is swingable, and rotation of the drum section causing each laminating head to advance to a laminating position facing a planar lamination surface provided in the lamination stage;
• and
• a rolling motion mechanism that rolls the curved holding surface on the planar lamination surface so that a delivery point of the sheet member formed between the curved holding surface and the planar lamination surface moves from a rear end to a front end of the sheet member in a rotational direction of the drum section while each laminating head is caused to move by the rotation of the drum section,
• wherein the rolling motion mechanism swings the curved holding surface of the laminating head at a position before the laminating position forward in the rotational direction and swings the curved holding surface rearward in the rotational direction in association with advancement of the laminating head by a rotation of the drum section, and
• wherein the laminating device comprises a displacement mechanism that displaces the curved holding surface outward in a radial direction of the drum section as the curved holding surface leaves a state of being swung forward in the rotational direction and approaches a reference orientation in which the curved holding surface is not swung forward or rearward in the rotational direction and that displaces the curved holding surface inward in the radial direction as the curved holding surface is swung rearward in the rotational direction from the reference orientation.
