Abstract
A method and apparatus are disclosed for producing a surface-structured, film semi-finished product made of a thermoplastic which is applied onto a prepared surface with numerous fine cavities provided in the form of pocket borings and is correspondingly shaped. The solidified plastic material is removed from the surface as a structured film, whereby the thermoplastic material which is inserted into the cavities and removed from the same forms a pile comprised of projections and naps. The projections which form the pile are stretch by combing, brushing, using a squeegee, and/or by squeezing by shearing in order to form naps.
