WELDED PART, METHOD AND DEVICE

摘要

The invention concerns a plastic assembly consisting of an axially symmetrical rigid or semirigid part (2, 3), for example a tube shoulder, and a flexible hollow body (1) provided with two ends, for example a laminated tube; said hollow body (1) enclosing and covering the periphery of the rigid or semirigid part (2, 3), thereby defining a contact zone (4, 5) between the two parts. The invention is characterized in that the rigid or semirigid part (2, 3) and the hollow body (1) are welded together over the entire contact zone (4, 6).
