Abstract
A method for producing three-dimensional molded parts from a fiber-containing material and a fiber processing device are described. In this case, a provision of separated fibers, an arrangement of the separated fibers to form at least one preform, wherein the at least one preform substantially corresponds to the shape of a molded part to be produced, and a pressing of the at least one preform to form a three-dimensional molded part take place. The fiber processing device at least has a feeding device for providing separated fibers; a premolding device, which has at least one premold for forming preforms from fibers fed separately, which corresponds to the final form of the molded part to be produced; a transfer device for transferring preforms provided via the at least one premold and made of fiber-containing material; and a molding device for pressing preformed preforms to form finished three-dimensional molded parts.
