Title:
CO-EXTRUDED TUBE WITH MOULDED CONNECTOR
Document Type and Number:
WIPO Patent Application WO/2004/046564
Kind Code:
A2
Abstract:
A method and apparatus for forming a tube and connector assembly (10,12:10,14). The tube (10) is formed in a co-extrusion process (16) to provide a multi-ply tube and the multi-ply tube is thereafter delivered to an injection die assembly (18,20) where a connector (12,14) is moulded onto the end of the tube (10). The moulded on connector provides a ready and efficient means of providing a connector for the tube and further encapsulates the tube end so as to preclude separation of the plies of the tube even in a heavy duty usage environment. The connector may comprise a coaxial connector (12) in which the central axis of the connector is coaxial with the central axis of the tube end portion over which it is moulded or may comprise a right angle connector (14) in which the central axis of the connector is at a right angle to the central axis of the tube end portion over which it is moulded.
