Abstract
An apparatus thermally laminates at least two materials together while minimizing wrinkles, ripples, curl, and color density loss in the laminate applying heat and pressure to the materials, by turning the laminate in a first direction away from a hotter laminating member causing a curvature of the laminate, and by turning the laminate in a second direction which reverses the curvature of the laminate.
