摘要： 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.
