FIELD: process engineering.
SUBSTANCE: invention relates to machine building and can be used for production of porous articles from nonwoven wire material. Device comprises coil with wire material and assemblies deforming the wire material, first of the latter intended for bead forming and second one for forming of porous blank. First deforming assy is arranged to reciprocate axially and consists of drive gear composed by helical gear segments alternating in circle and secured between two discs with opposite location of teeth at 90 degrees and drive polyurethane roller for making of special bead forming with mutually perpendicular adjacent teeth. Second deforming assy consists of cylindrical revolving mandrel an driven cylindrical roll arranged parallel about cylindrical mandrel and squeezed there against at adjustable force.
EFFECT: porous material with stable bonded structure, higher quality of the blank.
