  • Patent number: 9555969
    Abstract: A fabric belt for producing a corrugated cardboard web in a corrugated cardboard machine is joined together at the two ends thereof to produce an endless belt. An outer paper side facing the corrugated cardboard web and an inner load side assigned to the drive are formed. Connecting pieces to connect the belt ends have in each case at one end transversely with respect to the belt clips lying next to one another at a spacing, and are fixed at an opposite end with a connection section at the associated belt end. In the longitudinal direction of the belt, the clips of one connecting piece interact in a force-transmitting manner with the clips of the other connecting piece. The connection section of a connecting piece is held in a receiving gap of the belt that, starting from the belt end, extends between the paper side and the load side.
