Abstract

A goods-handling door having a raisable curtain for closing a door-bay, the door including two rigid side uprights disposed on either side of the door-bay, each upright including a slideway, the door further including a curtain disposed between the uprights, the vertical edges of the curtain sliding in respective ones of the slideways, each upright including a rigid web that faces said door-bay, each slideway including a vertical slot formed through said rigid web, said vertical slot being delimited by two edges, wherein each slideway further includes a flexible draft-proofing cloth interconnecting its two edges over substantially the entire height of the slot, thereby delimiting a vertical pocket on its side opposite from the door-bay, which pocket is designed to receive an edge of the curtain, said edge bearing flexibly against the bottom of the pocket, which bottom has sufficient clearance to absorb movements and deformations of the edge of the curtain.
