Abstract: The device comprises two groups of spinning nozzles (9, 10), which are arranged at the lower sides of two adjacent spinning beams (13.1, 13.2) and are connected with a melt source (1) or melt sources, two roller systems (26.1, 26.2) assigning the spinning nozzle groups for drawing and stretching the threads, and two winding devices (30.1, 30.2) assigning the roller systems, where one of the winding devices is selectively positionable in two operating points. The device includes two cooling devices assigning the spinning nozzle groups and a common climate air feed between the cooling devices. The device comprises two groups of spinning nozzles (9, 10), which are arranged at the lower sides of two adjacent spinning beams (13.1, 13.2) and are connected with a melt source (1) or melt sources, two roller systems (26.1, 26.2) assigning the spinning nozzle groups for drawing and stretching the threads, and two winding devices (30.1, 30.2) assigning the roller systems, where one of the winding devices is selectively positionable in two operating points. The device includes two cooling devices assigning the spinning nozzle groups and a common climate air feed between the cooling devices, where the cooling devices are controllable independent of each other. The winding device is arranged in a first operating point, so that the threads extruded from the both spinning nozzle groups are separately wound to coils into two thread bundles by the winding devices. The winding device is arranged in a second operating point, so that the threads extruded from the both spinning nozzle groups are wound to coils as a thread bundle by the winding devices. For drawing and stretching the threads, the both roller systems are couplable with one another, so that the threads of the both spinning nozzle groups are supplyable as two separate thread bundles or as thread bundle to the winding devices. A connecting unit, by which several individual threads are combined to several composite threads, is arranged to the roller system. The roller systems have two propelled rollers, one of which is selectively arranged to the roller system or roller systems. Two separate spinning pumps are arranged to the spinning nozzle groups and are connected with the melt source over melt pipelines and with spinning nozzles of the assigned spinning nozzles groups over distribution pipelines. An injection device is intended for providing an additive and is selectively connected with one of the spinning pumps or both spinning pumps. The spinning nozzles are kept in a linear arrangement by the spinning beams, where the spinning beams are parallely arranged with a distance to each other or in a row and are separately, heatably formed. The cooling devices are formed for cooling the filament bundles selectively with same or different units for guiding the climate air. The spinning nozzles are selectively formed by monofilament nozzle packages or multifilament nozzle packages. An independent claim is included for a method for operating a device for melt-spinning and winding multiple synthetic threads.
