Embodiment Construction
[0021] figure 1 Shown is a dryer operating with hot air with an omega (Ω) construction according to the prior art. The textile web 1 to be dried enters the dryer in the entry area 4 via a deflection drum 2 , winds around a gas-permeable flow-through drum 5 in a clockwise direction and exits the dryer again via a further deflection drum 3 . The circulation drum 5 and the two deflection drums 2 , 3 are arranged in a housing 7 into which hot air is introduced by means not shown. The hot air flows through the fabric web 1 , thereby drying it and is sucked in by a fan, not shown, via suction elements arranged on one or more end faces of the through-flow drum 5 . for example in figure 2 Suction piece 8 in. In this case, the throughflow drum 5 is placed under negative pressure, whereby different flow conditions occur in the dryer.
[0022] according to figure 2 , according to the invention, an at least partially air-permeable air guide cylinder 10 is arranged concentrically wi...
