Abstract: The invention concerns a cutting device (1) for reducing the width of a ready-made roller blind blank (28) comprising a roller tube onto which a fabric has been wound. The cutting device (1) comprises a mandrel (13), which is adapted to be inserted into and hold an end to be cut of the roller tube, and a knife arrangement, which is adapted to circumferentially cut first the fabric wound on the roller tube and then the roller tube on the mandrel (13) such that the width of the ready-made roller blind blank (28) is reduced. The invention also concerns a ready-made roller blind blank (28), which comprises a roller tube, onto which a fabric has been wound and which is adapted to be cut by means of a cutting device (1) according to the invention. For this the roller blind blank (28) comprises a disposable wrapping, which bears a visible measurement scale along at least one end portion of the roller blind blank (28).

Abstract: The present invention concerns a device (1) for preloading of a rewind mechanism (2) for a fabric (4) arranged on an elongated tube (3) or the like of a roller blind, a projector screen or the like. The rewind mechanism (2) is arranged to be essentially inserted into said tube (3) and includes a spring (10), that is tensioned when the fabric (4) is rolled out and relieved when the fabric (4) is rolled up onto the tube (3). The device (1) includes an outer mounting element (5), that is arranged to be attached to the tube (3), and an inner mounting element (6), that is arranged to be attached to an outer bracket (not shown), said mounting elements (5, 6) being rotatingly arranged in relation to each other about a longitudinal axis of said tube (3). A spring element (7) is arranged between said mounting elements (5, 6) and includes a sleeve (11), in which said spring (10) is arranged.
