Abstract
A filter bag for a filter system, comprising a number of parallel channels embodied by interconnecting, along parallel assembly lines distributed over pocket length, two opposite side walls of the pockets. The side walls meet at the open end of the pocket; a frame is introduced into each channel, the frame having two substantially parallel members which extend in a plane perpendicular to the main direction of the pocket, such plane being equidistant from the two assembly lines forming the lateral boundaries of the particular channel concerned. At the bottom bag end near the bag end remote from the open end of the bag, the two substantially parallel members meet by way of a bottom member which is substantially perpendicular to the plane of the two substantially parallel members - that is which extends substantially in the main direction of the bag.
