Abstract

Upper screen member for a pneumatic stowing line is slung adjustably on support roofbars and fitted with side discharge outlets. It is supplemented by bottom screening in the form of box claddings secured independently to the supports. The upper screen consists of a fine wire mesh mat folding up on a venetian blind principle whose top rim reinforcement is held by a hanger fixed to the backpoled roofbar. The reinforced bottom rim of the mesh mat is connected to an hydraulic power cylinder by means of a fitted rope, cable etc. The mesh mat system may have a number of reinforcements in the longitudinal sense, possibly consisting of wire ropes.
