Estimating the term…
The invention relates to a manufacturing process of equipment for use in the production of nonwoven fabrics and paper products. According to the present invention, a sleeve for an embossing roller is produced using additive manufacturing, specifically 3D printing. These technologies permit the preparation of pattern-forming and dewatering details in the sleeve in a single operation. The dewatering properties may thus be optimised for the selected pattern, resulting in uniform dewatering tailored for the pattern. Preferably, the technique used is stereolithography.
A method for preparing a sleeve for a drum for forming, pressing or molding a fibrous web, wherein the method comprises forming the sleeve by additive manufacturing.
A sleeve for a drum for hydroembossing a fibrous web, said sleeve being prepared using additive manufacturing.
