Amongst other things, the invention makes it possible to install and dismantle such screen arrangements simply and rationally. The process is carried out in that a door leaf section (2) is designed to be supported and guided by the said tracks (3, 4), that a lifting arrangement (11) is connected to each end of the door leaf section (2), that a plurality of elements (37, 38 and 2) appertaining to the screen arrangement is designed to be supported by the said door leaf section (2) which is conveyed by means of the said lifting arrangements (11) to the required height for subsequent installation or dismantling.</p> |
