[origin: WO8002832A1] A tube for yarn bobbins of a moulded plastic material which may be axially compressed, said tube being composed of a number of connected concentric rings (2), where the two end rings (1 and 3) are differently shaped with inner and outer cylindrical surfaces (4 and 6) or conical surfaces adapted to each other, said surfaces providing a seal, and where the cylindrical or conical surface is formed by arms (9) extending from the rings along generatrices, and the rings are connected with strings (11) shaped as springs which when stretched extend substantially parallel to the generatrices but which are located under the cylindrical or conical surface formed by the arms.
