Abstract

An apparatus for melt spinning and winding up synthetic yarns comprising a spinning appliance, a treating appliance and a windup machine. The treating appliance comprises a runoff godet for guiding the yarns before entry and distribution of the yarns into a plurality of winding stations in the windup machine, the runoff godet being arranged above the windup machine and guiding the yarns in a parallel side by side arrangement on its circumference. The runoff godet is arranged transversely to a winding spindle and above the windup machine, the windup machine comprising a plurality of head yarn guides which are disposed upstream of the winding stations and are arranged in a vertically oriented runup plane. To ensure a very low-friction guidance for the yarns, the invention provides that the head yarn guides of the winding stations are disposed downstream of the runoff godet immediately in the yarn path and such that on deflection of the yarns into the runup plane an angle of deflection of not more than 15° is not exceeded.
