发明名称 PROCESS FOR THE MANUFACTURE OF AN ACOUSTICALLY EFFECTIVE FOIL STACK FOR A VEHICLE HEAT SHIELD
摘要 The invention relates to a method and a device for producing an acoustically effective stack of films (9) from embossed film webs (5e, 5f, 5g, 5h). Said method and device are characterized in that at least two film webs lying one on top of the other (5a, 5b, 5c, 5d) are embossed together, are conveyed alo ng different routes (W, W1, W2, W3) and are subsequently combined into a stack (9), whereby neighbouring embossed film webs (5e, 5f, 5g, 5h) are laid down in a mutually offset manner in relation to one another, as a result of the different routes (W, W1, W2, W3). A particularly advantageous configuration of the embossing rolls (1a, 1b) produces film webs which have protuberances wit h a structure that resembles the drape of a fold.
