Abstract:
1. Device for creating a three-dimensional molded part ( 30 ) made from fiber material, comprising a multiple-part mold ( 1 , 2 ) having an inside ( 1 a , 2 a ) that determines at least partially contours of the molded part, a plurality of nozzles ( 4 ) that are adapted to blow fibers into the mold using an air flow, and the air flow then escapes through openings of the mold, so that the fibers accumulate on the inside of the mold, and the fibers are adapted to be bonded with each other through a supply of heat and are taken from the mold ( 1 , 2 ) after cooling as a molded part ( 30 ), the nozzles ( 4 , 24 , 34 ) are pivotable and pivot axes of the nozzles extend outside of the molded part and the fibers are adapted to be blown in by ones of the nozzles ( 4 , 24 , 34 ) that are activated at different times, and a programmable controller is adapted to pivot the nozzles ( 4 , 24 , 34 ) in a back-and-forth motion with a frequency of at least 0.3 Hz during an injection process.
