ABSTRACT:
The invention relates to a device for decorating and fixing a non-woven material (15) in the form of a web of endless fabric, said device comprising a screening drum (6) and a decoration shell (7) which surrounds the screening drum (6) from outside. The fibres (15) of the non-woven material, located on the decoration shell (7), are needled and fixed according to the decoration formed by the holes of the decoration shell (7) by means of energy-rich water jets (14) or air flows. The invention is characterised in that the decoration shell (7) and the screening drum (6) are interconnected by mechanical means (8, 9, 10) that can be easily detached. In a preferred embodiment, the decoration shell (7) comprises a counter-toothed ring (9) and the screening drum (6) comprises a toothed ring (8), said rings positively engaging in each other in such a way that a rotation of the decoration shell (7) and the screening drum (6) in relation to each other is prevented.
