The main goal of this project is to create a new machine able to crimp steel sleeves on concrete reinforcement re-bars for connection inside a concrete structure, by a mechanical splicing method . The crimping methocl has been patented in France and U.K (and pending approval for Europe) but the industrialrzation of this patent requires a lotofadditional researchand tests to develop the appropriate crimping machine, capable of achieving both production speed and sufficient tensile strength of the connection . The studv and creation of a prototype of a specific mobiie machine able to perform crimping on construction sites will be necessary and SME proposals - manufacturers of specia1 qualities of steel and mettalurgic heat treatments processes. and of the casting of special high grade mettalurgic accessories - would be interested to contribute to this project and work with the Patent Owner Company (Dextra Europe) and RTDs dedicated to study the specifications of the prototype, and to perform tests of the prototype, and material on construction sites . The interest of such a research is to create a new crimping machine able to increase the mechanical properties of concrete structures and achieve substantial economies thanks to production speed. and less wastage of steel . The here after SMEs are specialised in complementary technologies permitting to develop an ergonomic and efficient prototype to reach this goal . -Considering both economical and technological aspects developing such a prototype is much too complicate and risky without the contribution of major RTDs and perhaps an "other proposer" such as contractors .
