ABSTRACT:
Sealing apron device for a moving conveyor belt or loading trough of a belt conveyor, has at least one mounting plate which is fitted above the belt and which has a vertically adjustable sealing apron on a side wall. The underside of the apron interacts with the belt for sealing, and the sealing apron comprises a number of adjacent sections which are vertically slidable relative to each other on the mounting plate by means of slide guides on the mounting plate and the apron sections respectively. Each apron section is so fixed to the mounting plate with a clamping plate or bracket and fixing members that an apron section is clamped between the clamping plate and the mounting plate. A friction element between the clamping plate and sealing apron sections permits a downward movement of the section relative to the mounting plate, but impede an upward movement thereof.
