<p>The conductor channel is connected to a slit-shaped section and sealed with it via a displaceable packing system which has several longitudinal flexible packing guide plates. The packing guide plates (15) have two separate packings in the form of an inner packing (17) and an outer packing which have component pair of abutting, longitudinal edges (17) which lie on opposite sides of the slit-shaped section on the rigid packing carrier section (19) of the conductor channel (1). The conductor channel, in general, has a rectangular U-shaped cross-section. The rigid packing carrier section (19) consists of two, fixed, separate construction units on the upper edge (13) or the U-shaped-flange (3). The unit-sections carry a packing guide plate (15). The construction units are built up from oppositely placed, angular guide plates and the packing guide plates (15) are set in the flange (3) and are partially covered over by the angular flanges.</p> |
