Abstract
A sectional strip 5 with an outward-facing outside 10 and an inside 11 for roll-up, fold-up, and similar gates exhibits at its top 6 and bottom 7 a point of articulation 8 that extends over the total width of the gate for pivoting the adjacent upper and lower, identically shaped sectional strip in relation to the plane of the gate, which consists of the sectional strips that are not rolled up, when rolled up onto the armor of rolled-up sectional strips. The point 8 of articulation at top 6 is in the form of at least one perpendicular cylindrical sector 12 with an outward-facing surface 13 and the point 8 of articulation at bottom 7 is in the form of at least one cylindrical sector 14 with an inward-facing surface 15. The surface at top 6 and the surface at bottom 7 have radii 16 and 17 of curvature that are practically equal in length. The centers 18 and 19 of curvature of the radii of curvature of the surface at top 6 and of the surface at bottom 7 are located on a straight line and are at an equal perpendicular distance from the plane 23 of the gate, which is constituted by the outsides 10 of the sectional strips 5, with both straight lines coinciding with the axis of articulation of ech point 8 and 9 of articulation. The distance of the straight lines from the outside 10 is less than that to the inside 11.
