Abstract
In order to improve a retentions force of a silo closure, patterns with protrusions and recesses are proposed at least on insides of a support profile in particular portions, preferably also on outsides of a support hose and/or at least on one of the outsides of a cover foil.
Claims21
A silo closure, comprising:
- a trapezoid support profile;
- and
- an inflatable support hose disposed in the trapezoid support profile and configured for fixating at least one cover foil disposed between the trapezoid support profile and the inflatable support hose,
- wherein the trapezoid support profile includes an opening in a shorter side of two parallel sides of the trapezoid support profile,
- wherein the opening is defined by two bends of free arms of the trapezoid support profile, wherein the two bends are oriented towards the opening in a convex manner,
- wherein support profile protrusions and support profile recesses are provided at inward oriented slanted surfaces of the free arms and also at inward oriented convex bent surfaces of the two bends of the opening of the trapezoid support profile, and wherein the support profile protrusions press into a contacting outside of the at least one cover foil and increase a retaining force.
