A pocket filter in the form of a filtering block is provided with an assembly of channels open at one end to receive gas from which dust is to be removed, and is interleaved with the channels of another assembly open towards the other end and delivering the gas from which the dust has been removed. These channels have a generally square-shaped cross-section, and are connected to each other, for example by stitching lines, along their edges. During operation, the initial shape provided for the cross-section of the channels of the two above mentioned assemblies is maintained by tensioning these two assemblies with tensioners or the like, on which are fixed the edges of the outer channels of the filtering block. |
