The invention relates to a device and a method for the bonding of a textile web, whereby the textile web is guided over an idler drum into a bonding plant, led around a through-air drum and over a cooling drum and then led out again, whereby heated fresh air flows through the web and the through-air drum and the exhaust air is extracted from the bonding plant. According to the invention, it is intended that cooling air is directed onto the web ahead of the detachment point of the web from the through-air drum onto the web.

An apparatus for a thermal treatment of a textile web includes at least one drum with a perforated casing surface around which a material web can be at least partially wrapped, at least one connecting element, and a patterning shell with a plurality of openings separated by ridges fitted onto the casing of the drum. The patterning shell includes at least two segments detachably connected with aid of the at least one connecting element. The at least one connecting element is arranged on or integrated into a ridge.

A drying apparatus includes a dryer for a textile web. The dryer includes a drying chamber and at least one air-permeable drum arranged to rotate in the drying chamber. The textile web is guidable over a partial section of the circumference of the drum and heated drying air is flowable through the textile web. The dryer further includes a device to introduce heat for heating up the drying air. The device includes an internal hot gas source and an external hot gas source. The internal hot gas source is a component of the dryer and the external hot gas source is arranged peripherally to the dryer and includes a hot gas line connected at least indirectly to the dryer.
