Abstract:
1. A device for use in a molding tool, comprising: a system of rhomboid flat elements of an elastic deformable material arranged in at least two layers that are mutually relatively rotated with respect to each other, a first upper cloth of an elastic deformable material and a second lower cloth of an elastic deformable material, which cloths are imperviously joined along lateral edge areas thereof and form an adjustable impervious chamber, wherein the system of rhomboid flat elements are enclosed in the chamber formed by the joined upper and lower cloths so as to form a flexible mat, and wherein the flexible mat is mechanically connected to free ends of actuators in such a way that a given point on a surface of the flexible mat has a location determined based on a position of a free end of a respective one of the actuators which is associated with the flexible mat at said given point.
