Abstract
A flexible product, more particularly an information-carrying disc, is removed from a carrier plate, more particularly a mold, by creating a partial vacuum at the side of the product facing away from the carrier plate. While the product is being displaced in a direction facing away from the carrier plate under the influence of the partial vacuum, the product is guided in such a way that it is displaced over the greatest distance at two opposite ends and the displacement of the parts of the product situated between these ends decreases gradually towards the center of the product.
