A path of conveyance is provided with a membrane for transporting a material over a length section of the path towards a discharge end; the membrane demarcates from the material a pressure medium chamber situated at the bottom of the path, extending transversely to the direction of conveying and being adapted to be acted upon by means of a pressure medium; as viewed in a longitudinal section through the path the membrane comprises two portions of which the first portion situated relatively near the discharge end of the path is reinforced in the longitudinal direction, and the second portion is left flexible; the edge of the reinforced first portion which is situated relatively near the discharge end of the path is also left flexible; at least the second, flexible portion of the membrane is briged by means of a covering skin. |
