Abstract
For producing cushionings, a first layer (11) of thermoplastic, weldable synthetic material is placed into a templet (17), whereupon a padding material (12, 13, 14, 15) is placed thereon as an intermediate layer. The padding material thereby keeps uncovered areas of the first layer (11), which areas are subsequently welded with a second layer (16) of thermoplastic, weldable synthetic material placed onto the padding material (14). Welding is only effected at areas in which the layers (11, 16) are, without interposition of padding material, directly pressed one against the other. The inner contour (18) of the templet (17) essentially corresponds to the outer contour of the layers (11, 16). The templet (17) is formed of a material having high dielectric losses, so that a tight welding seam is reliably obtained at the edge of the layers (11, 16).
