METHOD AND APPARATUS FOR PRODUCING COTTON WOOL PRODUCTS
The invention relates to a method for producing a cotton wool product, in particular for producing cotton pads for cosmetic purposes, comprising the following steps: - preparing a preliminary mat which is made at least predominantly of cotton fibers, - compacting said preliminary mat by using a plurality of hot high-pressure gas jets. For the apparatus it is provided that the device for compacting (2, 12', 14, 15, 15', 16, 16') the preliminary mat (7) comprises a device for subjecting the preliminary mat (7) to hot gas at a high pressure.
