ABSTRACT:
The invention concerns a process for the manufacture of textile or wire-reinforced hoses, the components of which are placed while the inner tube is supported by a mandrel.
According to this invention, the mandrel is made of a congealable fluid which is introduced inside the tube and then cooled and solidified during manufacturing steps wherein the formed assembly will resist mechanical stresses which would not be endured by the sole constituents of the hose. The mandrel is thereafter brought back to a liquid form to be drained off.
The invention is applicable to the manufacture of medium and high pressure hoses.
