ABSTRACT The edge of a cambered flexible sheet to be rolled for flattening, usually the luff of a marine sail, is provided with a first securing means which extends along and is attached to only a predetermined intermediate portion of the edge to be rolled and which is employed to connect that edge portion to the stay or other rotatable member about which rolling is to occur. The same edge of the sheet is also provided with a second securing means comprising flexible means which is attached to the sail and surrounds or embraces the rotatable member in such fashion that, before rolling of the flexible sheet on the rotatable member, and also during that early state of rolling when only the intermediate portion of the edge is rolled, the second securing means supports the edge of the sheet in proper relation to the rotatable member. The second securing means can extend continuously along substantially the entire edge of the sheet to be rolled. The flexible means of the second securing means surrounds the rotatable member in such a fashion that, before the rotatable member is turned, the rotatable member is free to turn relative to the second securing means.
