Abstract
A hose assembly (1) is provided having a structure (2), in which the structure (2) has circumferential ribs (3), the axial extent of which varies, preferably periodically, along a circumference, and locally limited gap-filling elevations (4), as a result of which, a braiding impression is produced, without a separate braiding of the hose assembly (1) being carried out. The structure (2) is applied by at least two embossing dies (7), in particular embossing rollers (8), which are rollable on the hose assembly (1), in particular are rollable in synchronism on the hose assembly, and are part of an extrusion process.
Claims21
A hose assembly (1), comprising:
- an external structure (2) that is embossed.
A hose assembly (1), comprising:
- an external structure (2) with at least one circumferential rib (3), wherein the at least one circumferential rib (3) has an axial extent, which varies along a circumference, and at least one of a) at least two of the ribs (3) are identical, or b) gaps formed by a reduction in an axial extent are filled by locally limited elevations (4).
A device (12) for introducing a structure (2) on a hose assembly (1), the device (12) comprising:
- at least two embossing dies (7), located downstream of an extruder, and the at least two embossing dies (7) are rollable on a hose assembly (1).
A method for introducing a structure (2) on an extruded hose assembly (1), the method comprising:
- applying a second layer (11) to a first extruded layer (10) in an integrally bonded manner;
- and
- applying a circumferential structure (2) to the second layer (11) via at least two embossing dies (7) which are rollable on the hose assembly (1).
