Production of concrete ties for railway tracks

摘要

The method for manufacturing a concrete sleeper with partially embedded holders (8) for rails comprises inserting the holders into holes (30) in the wall (24) of a sleeper mould which is then filled with concrete. The holder is kept in position during moulding by exerting force on a section (20) which remains outside the mould An Independent claim is included for a system for carrying out the above process.
