A filter sleeve of tubular form is made by connection of the edges of textile material by longitudinal seam includes working and final parts, in whichworking part is equipped at least with one cross reinforcing element in the form of a metal ring located inside circumferential butt, end parts are executed with the sleeves, one of which is formed by bending of textile material on the perimeter of the end part of the sleeve and is connected with it by circumferential seams. The second sleeve is formed by bending of flatly folded end part of the sleeve to the outer side and it is connected with it by transverse seams. Sleeve is formed by bending of flatly folded end part of the sleeve to its outer side, executed with formation creation between the edge of bending and said seams of a through cavity for installation in it of the element for fastening of sleeve in the filtering plant.
