Abstract
An apparatus includes upper and lower pressing tools arranged on platens that move relative to one another in a stroke direction. A slider unit moves in a direction transverse to the stroke direction, coordinated with the relative motion of the platens. In a retracted position the slider unit is displaced laterally from the lower pressing tool. In an active position the slider unit protrudes laterally over an edge portion of the lower pressing tool. Pressure actuators between the lower platen and the lower pressing tool apply an increased active pressing force on the lower pressing tool toward the upper pressing tool. Through the combined motions, the pressing tools press a laminated component including a cover layer on a substrate, and the slider unit folds and presses a protruding margin of the cover layer around an edge and onto a back surface of the substrate to form a folded-back rim.
