  • Patent number: 10336550
    Abstract: The disclosure relates to a support structure for supporting a belt of an enclosed belt conveyor between two transport units and a corresponding method. The support structure between two transport units includes a first end element having a main extension in a longitudinal direction, a width extension in a width direction orthogonal to the longitudinal direction, and a height extension in a height direction orthogonal to the longitudinal and the width direction. At least one guide assembly is arranged to engage opposite longitudinal edges of the belt. A first telescopic element is connected to the first end element, wherein an outer end of the first end element has a first end connector arranged to form a connection with a first transport unit.
