An auxiliary transport device for transporting a chain part of a web conveying mechanism, which mechanism guides the start of a web of material through a processing device, comprises a transport device, having a length of at least the transit path of the web of material, for engaging and moving the chain part of the web conveying mechanism, as well as a drive device arranged outside the device for moving the transport device and guide, which are arranged along the transit path of the web of material, for guiding the transport device and the chain part through the device.

Auxiliary transport device

A burner unit for heating a gaseous medium includes a heat exchanger provided with tubes, a space between the tubes connected on the upstream side to a feed duct for the gaseous medium; a combustion chamber connected to the downstream side of the space between the tubes; a burner placed in the combustion chamber; and a fuel supply duct connected to the burner. The side of the combustion chamber remote from the heat exchanger is connected to a first end of the tubes; and a flue gas outlet duct is connected to the other end of the tubes. The elongation of the tubes forming part of the heat exchanger renders the use of a conventional tube plate superfluous. Thus, damage resulting from thermal stresses is avoided.
