According to the fire, this ϊΓ-part is avoided by • having protruding angle flange connections waived "wircQ and the butt joint d.by material ^ consisting of sheet metal strips, band iron odvdgl, takes place that at-one end -of-the-weft it inside and at the adjacent end of the next shot is attached outside or vice versa -

Both parts will go through. First connected to each other, a plastic or flexible seal being advantageously inserted between the ends of the sections viird ^ This makes the connection operationally reliable sealed and also shows a certain flexibility in the longitudinal direction of the channel, as in longer channels is required. to a possibly to exclude the occurrence of the departure of Meten as a result of temperature differences,

In addition, the modern Plach connection has the advantage of being easy to manufacture, since - "-." ■ 'none
