  • Method and assembly for the production of a homogenous composite pipe of unspecified length
    Patent number: 8967220
    Abstract: A method of forming a homogenous composite pipe of unspecified length from strips of fiber reinforced thermoplastic material is disclosed. A mandrel is arranged stationary in a process direction to extend freely from a first supported end to a second end. A slip-sheath is applied about the mandrel. The thermoplastic material strips are wound about the slip-sheath. A section of the thermoplastic material strip winding is consolidated. The slip-sheath is formed from tape material which is applied longitudinally onto the mandrel surface. The slip-sheath is connected to a puller arranged downstream of the mandrel in the process direction. Consolidated pipe sections are pulled off from the second end of the mandrel in synchronization with the winding and consolidation. An assembly for carrying out the method.
