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...

Abstract

The invention relates to a device and a method for thermally treating a textile material web, having at least one through-air drum with a perforated lateral surface and with a casing which is at leastpartly looped by a material web, wherein a heated gas flows through the material web and the casing of the through-air drum. The invention is characterized in that an air conducting cylinder (10) with a plurality of openings (13) is arranged within the through-air drum (5), and the heated gas is drawn off via the interior of the air conducting cylinder, the air or gas permeability of the air conducting cylinder (10) being adjustable.

Description

technical field [0001] The invention relates to an apparatus, in particular a drum dryer or a thermobonding machine, for the thermal treatment of a textile fabric strip according to the preamble of claim 1, and a method for the thermal treatment of a textile fabric strip. Background technique [0002] Processes for the thermal treatment of woven fabric strips consisting of fibrous webs or nonwovens include hot-air drying or hot-air consolidation in through-flow dryers, in which heated gas, such as air, flows through the fabric strip and thereby dries or Reinforced fabric straps. For drying or consolidating textile fabric webs, dryers are known in which one or more drums are arranged in a housing. The woven web is conveyed to the dryer via the opening in the drying chamber by wrapping the woven web over a large part of the circumference around the drum and then being guided around the next drum and / or being led out of the drying chamber again. Usually, fresh air is also con...
