Abstract
Oppfinnelsen vedrører en anordning for tilvirkning av et dobbeltvegget termoplastisk rør med en rørmuffe. Ved tilvirkningen av rør med derme anordningen oppstår det et tilnærmet ringformet rom (A) som defineres gjermom et ekstruderhode (1), en første slange (2) som ekstruderes i en formturmel (4), og en andre slange (5) som ekstruderes i den første slangen (2). Oppfinnelsen forutsetter at rommet (A) er forbundet med et trykkgassreservoar (24), slik at trykkendringer i rommet (A) dempes gjermom trykkgassbeholderen.
