Abstract: A melt spinning device for producing synthetic threads includes at least a spinneret apparatus, a cooling apparatus, a processing apparatus and a winding apparatus. An automatic operating device is provided for carrying out at least one operator action. The automatic operating device has at least one movable robotic arm, which can be coupled selectively to one of a plurality of exchangeable tools in order to selectively carry out a plurality of operator actions during a start-up and/or during a maintenance interval and/or during thread production. Thus, a high level of flexibility in the automated operation of the melt spinning device is ensured.

Abstract: Particular techniques involve a device for wetting multiple threads with a fluid, and a dosing pump which is connected to the wetting means by multiple conveying lines. The dosing pump has multiple conveying means for generating multiple dosing flows of the fluid and has multiple pump outlets, to which the delivery lines are connected. The conveying means are formed by at least one planetary gear set arranged between housing plates. To achieve, as far as possible, a uniform throughflow without a significant dead space volume, multiple planet gears of the planetary gear set are guided freely by a centering plate between adjacent housing plates. The planet gears of the planetary gear set have in each case one passage opening, which are connected by a channel system to a central pump inlet. It is thus possible to realize close fits and flushing of gaps.
