Abstract

Zvýšení mechanické pevnosti vláken. Uvedeného účelu se podle vynálezu dosáhne deformací kulových částic prášku valením mezi pracovními povrchy válců, z nichž jeden válec je opatřen kuželovým pracovním povrchem. Současně se příčné vrstvy tvořících se vláken posouvají vůči sobě navzájem zakruoováním.Increasing the mechanical strength of the fibers. This purpose is achieved according to the invention deformation of the spherical powder particles by rolling between the working surfaces of the rollers, of which one cylinder is provided with a conical working surface. Simultaneously, the transverse layers forming the fibers shift relative to each other by twisting.

Zvýšení mechanické pevnosti vláken. Uvedeného účelu se podle vynálezu dosáhne deformací kulových částic prášku valením mezi pracovními povrchy válců, z nichž jeden válec je opatřen kuželovým pracovním povrchem. Současně se příčné vrstvy tvořících se vláken posouvají vůči sobě navzájem zakruoováním.Increased mechanical strength of fibers. This object is achieved by the deformation of the spherical powder particles by rolling between the working surfaces of the rollers, one of which is provided with a conical working surface. At the same time, the transverse layers of the forming fibers are displaced relative to each other by curling.

Claims

P R B D MEASURES OF THE INVENTION

CLAIMS 1. A method for producing metal fibers, comprising deforming spherical powder particles by rolling them between two working surfaces, characterized in that, in order to increase the mechanical strength of the fibers, during deformation of the transverse layer of the forming fibers, they are displaced relative to each other by twisting.

Device for carrying out the method according to claim 1, provided with rollers arranged with a gap between their working surfaces and provided with drives for their rotation, characterized in that in order to increase the mechanical strength of the fibers one of the rollers (1, 2) is provided with a conical working surface .

Device according to claim 2, characterized in that the second roller (2) is provided with a conical or cylindrical working surface.
