Abstract
A crossing apparatus for use with a tunnel-shaped bellows mounted between two vehicles connected to one another in an articulated manner in which an apron bridges a gap between the side wall of the bellows and a turning platform. The apron has folds corresponding to the side walls. It also consists of material strips, two each of which are connected to one another at the longitudinal edges belonging to one another by apparatus of rail-like profiles. The apron-clamping profiles are brought together at their top ends with bellows-clamping profiles of the respective side wall. Each apron-clamping profile has, between its ends, a gap-bridging course located at a corresponding distance from the respective side wall. Each apron is a structural unit comprising a number of apron-clamping profiles and a material web. Each apron-clamping profile forms a frame which is closed in itself from two partial profiles. One partial profile is straight and extends in parallel to the side wall of the bellows. The second partial profile is arc-shaped and is attached at its top ends with straight sections to the first partial profile. The first partial profile of the apron-clamping profile has a groove-s…
