Definitions
- the sealing function is solely due to the different thermal expansion of the parts joined together. That is, the sealing function only occurs at temperatures in the region of the polymer melting point. Due to the increase in volume of the hollow body, it then sits absolutely firmly and gap-free in the hole and also seals completely on the end faces. After cooling, the parts are back to normal ambient temperature easy to disassemble. Because the hollow body is only in the interchangeable Component is embedded, this component can also be hot Dismantle from the fixed component and another cold one Replace the component with the hollow body flush with the face up to the sealing surface. To achieve this, the two components are attached to each other by screws, whereby - as already mentioned above - the contact surfaces are completely flat and are smooth.
- melt spinning systems with melt channels, where mixers are used as close as possible to the spinneret need, but also where mixers elsewhere in the melt line accessible or quickly exchangeable.
- the hollow body can be very short, but the should Length not less than half its outer diameter. A diameter to length ratio of 1: 1 is optimal.
- the length of the cladding tube or hollow body is determined by the length of the mixer Mixer determined, the upper limit from the dimensions of the bearing interchangeable component.
- a tube 10 which can also be hot during assembly, has one completely flat flange 11, one with the also completely flat flange 12 other pipe 13 or any component that is installed cold, is connected by screws 14.

Claims (8)
- Système d'assemblage comprenant
un élément (11) à montage fixe, qui comporte un premier canal pour matière en fusion (17),
un élément (12), qui est fixé de manière amovible contre l'élément (11) à montage fixe et qui comporte un deuxième canal pour matière en fusion (18) et une forure de type logement (19), les deux éléments (11, 12) étant munis de surfaces de contact, et
un élément d'étanchéité, qui est posé dans la forure de type logement (19) à fleur de la surface de contact pour rendre étanche la transition entre le premier et le deuxième canal pour matière en fusion (17, 18), l'élément d'étanchéité étant formé par un corps creux (15) cylindrique, lisse sur la face extérieure et muni d'une forure axiale (16) pour le passage de la matière en fusion, lequel est réalisé dans un matériau dont le coefficient de dilatation thermique est supérieur à celui du matériau de l'élément (12) amovible qui l'entoure,
caractérisé en ce que les surfaces de contact sont entièrement planes et lisses et l'élément à montage fixe (11) et l'élément amovible (12) sont fixés l'un à l'autre par des vis (4, 14), de telle sorte que l'élément amovible (12) peut être démonté à l'état chaud ou froid. - Système d'assemblage selon la revendication 1, caractérisé en ce que les faces de contact du corps creux (15) et de la forure de type logement (19) sont choisies de telle sorte que ces éléments peuvent glisser facilement l'un dans l'autre à température ambiante et sont fermés en assemblage affleuré l'un par rapport à l'autre, et en ce que, en raison du coefficient de dilatation thermique plus élevé du corps creux (15), celui-ci, en présence de la température du polymère en fusion, est logé de manière absolument fixe et sans jeu dans la forure de type logement (19) et assure l'étanchéité complète également au niveau des faces frontales.
