  • Method and apparatus for curved-surface transfer
    Patent number: 6110316
    Abstract: In order to produce a decorative laminate by adhering a transfer printing sheet to the three-dimensional irregular surface of a base, solid particles (P) are caused to collide with the transfer printing sheet (S) from the back surface thereof with the transfer printing sheet (S) facing the irregular surface of the base (B), and the transfer printing sheet (S) is brought into pressure contact with the irregular surface of the base (B) by utilizing the collisional pressure, thereby transferring the transfer printing sheet (S) to the base (B). In the case where a thermally stretchable transfer printing sheet is used, it is better to conduct transfer printing by heating at least one of the base, the transfer printing sheet, the solid particles, and so on.
