Verfahren zur farblosen, plastischen Musterung und Verfestigung einer Warenbahn und Vorrichtung zur Durchführung des Verfahrens

摘要

The invention concerns a method for producing three-dimensional colourless designs in a non-woven fabric or like material entirely bonded. Said method consists in subjecting the fibers to a blowing process through openings which form the design, then in optionally bonding them in the openings, since the fibers in the openings are only displaced therein with limited depth, and are subsequently needle bonded against a supplementary support.
