ABSTRACT:
A device for creating a three-dimensional molded part (30) made from fiber material using of a multiple-part mold (1, 2) whose inside (1a,2a) determines, at least partially, the contours of the molded part. The fibers are blown into the mold by an air flow using a plurality of nozzles (4) and the air flow then escapes through openings of the mold, so that the fibers accumulate on the inside of the mold, whereupon the fibers are optionally compressed locally before they are bonded with each other through the supply of heat and are finally taken from the mold (1, 2) as a molded part (30). The blowing direction of the nozzles (4, 24, 34) can be pivoted and the pivot axes extend close to the outside of the molded part and the fibers are blown in by the nozzles (4, 24, 34) that are activated at different times.
