TETNINGSRING AV ELASTISK MATERIALE MED ARMERING

摘要

The invention relates to objects composed of elastic material such as flattened helix or coil spring for a reinforcing or strengthening means wherein the reinforcing or strengthening means can be two helix or coil springs rolled together, one of the springs having a right-hand helix and the other a left-hand helix. If desired the strengthening and reinforcing means can be embedded within the elastic material such as a rubber sealing ring or it can be arranged on the outside of the object such as a hose clamp. Dependent upon the function and application of the object, the spring can have the form of a substantially flat ring, a hollow cylinder or a frustum of a hollow cone.
