A method for producing solidified fiber bundles includes applying a melt or solution to a carrier web forming a viscous coating, applying parallel filaments under tension to the carrier web, and pressing the filaments into the viscous coating, forming an impregnate. The coating is partially solidified until a plastically deformable state of the impregnate is obtained by vaporizing the solvent, thermal curing and/or cooling. The impregnate is rolled onto a winding core to form a roll while maintaining a winding tension of the filaments in the impregnate. The outer roll is fixed on the winding core by a sleeve and/or by adhesive tape. The impregnate is solidified by vaporizing the solvent, thermal curing and/or cooling. The solidified impregnate is divided up to form solidified fiber bundles. A pressure produced by the winding tension of the filaments in the impregnate is exerted on the roll. 116-. (canceled)17. A method for producing solidified fiber bundles , which comprises the steps of:a) applying a melt or solution to a sheet-shaped carrier layer, thereby forming a viscous coating;b) applying parallel filaments under tension to the sheet-shaped carrier layer having the viscous coating;c) pressing the filaments into the viscous coating, thereby forming an impregnate;d) rolling the impregnate onto a winding core to form a roll while maintaining a winding tension of the filaments in the impregnate;e) solidifying the impregnate by at least one of vaporizing a solvent, thermal curing and cooling resulting in a solidified impregnate, wherein a pressure produced by the winding tension of the filaments in the impregnate is exerted on the roll during a performance of step e); andf) dividing up the solidified impregnate for forming the solidified fiber bundles.18. The method according to claim 17 , wherein the melt is a melt of a thermoplastic plastic claim 17 , a thermosetting synthetic resin claim 17 , a pitch and/or a sugar.19. The method according to claim 17 , wherein ...
