Patent ID: 10661204

Abstract:
A method of sealing a filter bag at the stitched joints of the filtration material, consisting in forming the filter bag out of at least one filtration material piece, whereupon the surface of at least one filtration material edge being joined is covered with a liquid or semi-liquid layer of a sealant in such a way that the filtration material edges being joined are in contact with one another at least on the surface covered with the sealant. After the sealant layer has been applied, the filter bag elements prepared beforehand are combined together permanently by sewing them with a thread. A filter bag formed of at least one filtration material piece whose edges (2) and (3) are joined together with a thread (5), with at least one stitch, is characterised by the fact that at the stitched places between the adjoining surfaces of the filtration material edges (2) and (3) being combined there is a sealant layer (4), applied before sewing.
