  • Patent number: 8070660
    Abstract: A device for managing a retractable sheet that is wound on a roller by the action of a spring that may be extended by pulling on the exposed edge of the sheet wherein the device is used for printing messages thereon or for obscuring the view of nearby items. The device is easily changeable for multiple uses as the roller containing the sheet is separable from the main unit, allowing reuse of the more complex and expensive components of the device. A brake on the device prevents the spring from unwinding when the roller is removed. A damping mechanism limits the retraction speed of the sheet, which the damping mechanism being disengaged when the sheet is being pulled out. A cover is provided to obscure the main part of the unit and to prevent tampering. A unique slot configuration allows for easy, tamper-resistant installation of a header card. A pull tab is made of inexpensive components and is designed to allow for easy placement of a graphic label.

  • Patent number: 6723032
    Abstract: A segmented roll has a plurality of end-to-end mounted roll segments (10, 10′), each adapted to rotate on bearings supported on a separate support shaft (11). In both axial end surfaces of the support shafts (11) of the roll segments (10) there are coupling means such as an annular projection and an annular recess serving to disengageably connect two adjacent roll segments (10) to each other. The support shaft (11) has at least two parts (16, 18) whose mutual disposition is made alterable for the purpose of altering the axial length of the support shaft (11) so much that the coupling means (29, 41) of the facing axial ends of two adjacent roll segments (10) can be engaged and disengaged with each other. This arrangement makes it possible to change a single roll segment from the central area of the segmented roll without the need for disassembling the entire row of roll segments.
