The process is implemented using a cylindrical tube which is sufficiently curved for it to house the "lastra" or inner male mould. The tube and the "lastra" are placed over a female mould formed by two pieces which are capable of rotating on their own axes, both having a certain conicity. The tube acquires the desired shape by means of pressure and the "lastra" is easily removed by extraction. Applicable to the manufacture of tubes for cannulae, for clinical applications. <IMAGE>
