Abstract
A temple unit has a rod of metal damask with a spiral-shaped structure butt-soldered to a rigid metal profile. The rod is inserted axially into a clear plastic shell having a softness of shore-D-hardness less than 20 according to DIN No. 53 505, the West German national standard. The plastic shell is silicone rubber or polyurethane foam with very low resilience so that the unit exhibits a straight rod form in the semifinished state.
