Abstract

A molded component is produced by heating a non-woven material web to bring it into a plastically deformable state, and then plastically deforming the non-woven material under pressure between two mold tools of a molding apparatus. The mold tools define therebetween at least one or preferably several mold cavities that respectively simultaneously form molded products therein. A cut is formed in the plastically deformable non-woven material web, preferably between two adjacent mold cavities, immediately before and/or during the molding step. The cut facilitates a pulling or flowing of the non-woven material away from the cut and toward a respective mold cavity to facilitate the molding deformation thereof while avoiding excessive stretching and thinning of the non-woven material, especially at the transition area between adjacent mold cavities.
