Abstract
A bellows is provided as part of a crossway between two vehicles connected to each other in an articulated manner or as a telescopic gangway, with a material web which is provided with a layer of synthetic material. The material web has a top (upper) side made of a textile and a bottom (under) side made of textile (11, 12). The spacer fibers/pile threads (13) are provided between the top side and the bottom side, such that a space between the top side and bottom side results when the material web is in a non-loaded condition.
