ABSTRACT:
A rollup door comprising a door leaf of increasing width from top to bottom and having a narrower part on the top and a wider part on the bottom, and flexibility in the rolling direction; channels for guiding the door; and two modules for rolling and unrolling the door leaf so that a number of leaf layers do not come in contact. The modules are situated on each side of the door, have the same center axes and are successive radially enlarged so that on opening and closing of the door, the narrower and wider parts of the leaf engage the smaller and larger parts respectively of the modules.
