Definitions
- the third air baffle can be extended into the peripheral area of the milling drum, whereby the air flow tangential from the second air baffle to the milling drum is also deflected in a direction running essentially parallel to the bale surface.
- Fig. 2 shows a cross section through the milling device
- a third air baffle 26 is arranged below the incoming air flow and serves to deflect the air flow in a direction essentially parallel to the bale surface 20, namely towards the milling rollers 3 and 4.
- the third air baffle plate 26 can be kinked or curved to allow deflection with the least possible pressure loss and avoiding air turbulence, taking into account the angle of incidence of the incoming flow.
- the section of the third air baffle 26 running downstream of the air duct 2 is preferably aligned parallel to the bale surface 20 and rests on this bale surface.
- the third air baffle 26 and the box formed from the first and second air baffle 22, 24 are expediently fastened to the grate bars 17.

Abstract
Dans un dispositif pour démêler des balles de fibres compactées en matière textile au moyen d'au moins un cylindre fraiseur (3, 4) agissant sur la surface (20) des balles de fibres et respectivement d'un cylindre presseur (18) disposé en amont et en aval du cylindre fraiseur (3, 4), parallèlement à celui-ci et dans son sens de mouvement, une hotte d'aspiration (21) située au-dessus du cylindre fraiseur (3, 4) aspirant dans un courant d'air les bourres enlevées, il est prévu qu'entre le cylindre presseur (18) et le cylindre fraiseur (3, 4) soit disposé sur toute la longueur de ce dernier un canal de guidage d'air (2) parallèle aux cylindres fraiseur et presseur (3, 4, 18) et formé de plusieurs tôles de guidagae d'air (22, 26).In a device for disentangling balls of compacted fibers made of textile material by means of at least one milling cylinder (3, 4) acting on the surface (20) of the balls of fibers and respectively of a pressing cylinder (18) arranged in upstream and downstream of the milling cylinder (3, 4), parallel to the latter and in its direction of movement, a suction hood (21) located above the milling cylinder (3, 4) sucking in a current d 'air the wads removed, it is provided that between the pressing cylinder (18) and the milling cylinder (3, 4) is arranged over the entire length of the latter an air guide channel (2) parallel to the milling rolls and presser (3, 4, 18) and formed of several air guide plates (22, 26).
