Abstract (en)

[origin: EP0839481A2] The inner core comprises wave-shaped longitudinal and cross ribs (1,2,3), the waves of the ribs being meshed together. The waves have a trapezoidal shape. The length (4) of the shorter side of the trapezium is virtually equal to the width (5) of the longitudinal and the cross ribs. The ribs (1,3) in relation to the wave-type formation have an even surface (6) only interrupted by cross slots. The ribs are next to one another, turned through 180 degrees. The two types of ribs can be equally shaped and have a wave formation. In the mesh, the wave valleys of the ribs engage in the wave peaks of the cross ribs and vice versa.
