Abstract: A support for curtains, particularly curtains of the adjustable sun-louver type, comprises a plurality of carts fitting slidably in a slideway and being interconnected serially to one another by a string attached to each cart by means of a corresponding anchor member effective to bias the same to huddle into side-by-side bights above the carts, with the latter packed together in a gathered position. Each anchor member comprises at least one support arm jutting out from the corresponding cart and adapted to hold the string some distance above the corresponding cart.
