The suction system (9) for a bobbin winder, to produce cross wound bobbins, has an acoustic damper (14) at the outlet side of the fan housing (12), which is at least partially let into a base frame (2) of the end frame (1) of the textile machine. A housing of the acoustic damper (14) is removably fitted into an opening in the cover plate (3) of the base frame (2), positioned between two stiffening carriers (4) of the base frame (2). The acoustic damper (14) is connected to a further acoustic damper (18) by an angled channel unit (15), which is at the acoustic damper housing in a release mounting, and lowered at least partially into the base frame (2) of the end frame (1). The second acoustic damper (18) is connected to the spinner air conditioner (16') at the upper side through a channel link (20). The acoustic damper (14) can be connected directly to the air conditioner for the spinning shop, in the shop floor (17), through the angle channel unit (15). A damping material is within the housing, protected against the exhaust air flow by perforated plates, and is placed at least near the cover and at the end sides of the acoustic damper housing. Air guide plates are sited within the acoustic damper housing. The second acoustic damper (18) is composed of an inner shell with a base plate and U-shaped perforated plates which cover the damping material to the flow channel.
