Consumable and disposable cartridges (200) for laminar roller screens featuring quick installation and replacement by means of clip type means (41) or the like. They comprise a flexible sheet (15) which can change between a straight lined, curved or right angled path by means of cylindrical tubular means (40) or the like. They are associated to peripheral frames of the open space to be enclosed. Inside of it there is a rotation drum (5) for a flexible sheet, a torsion spring (12) causing the rotation drum to rotate so as to roll the sheet and a tubular element being of the same height as the sheet. There is also an actuation knob (13) which regulates the spring tension, and a tubular casing (6) delimiting the cartridge from which the sheet goes in and out. It further comprises anchoring and guiding means of the spring inside the drum, and a cover (28) of the casing to receive the detachable coupling of the actuation knob. |
