(57) Abstract :
The invention relates to a covering device (42) for suction drums (9, 9a) of compaction devices of adjacent drafting system units
(1) of a spinning machine, where the suction drums (9, 9a) are disposed coaxially on a longitudinal shaft (10) and have a ringshaped
opening (OE), in each instance, on their opposite sides, axially at a distance from one another, through which opening a
suction insert (50, 50a), in each instance, connected with a suction source (P), projects into the interior (IR) of the suction drum, in
each instance. In order to protect the interior (IR) of the suction drums (9, 9a) from contaminations and uncontrolled air streams, it
is proposed that the covering device (42) is attached between the adjacent suction drums (9, 9a) and consists of covering elements
(84, 85, 86, 87, 92, 93) that lie opposite one another and are connected with crosspieces (R1, R2, R3, R4, R5, R6, R7), which
elements stand opposite the ring-shaped openings (OE) of the suction drums (9, 9a) that remain adjacent to the suction insert (59,
50a), in each instance, and cover these, at least in part.
