Apparatus for making a spunbond nonwoven from monofilaments where a spinneret spins the filaments, a cooler cools the spun filaments, and a stretcher stretches the filaments. An intermediate passage is provided between the cooler and the stretcher, the intermediate passage having at least two converging passage sections provided one after the other in the travel direction of the filaments. The upper passage section in the travel direction of the filaments has a shorter length than the lower passage section. The ratio of the inlet width BE to the outlet width BA of the upstream passage section is 1.5 to 5.5, and the ratio of the inlet width bE to the outlet width bA of the downstream passage section is 1 to 4. To be published with FIG. 2B

Synthetic threads melt spinning, drawing and winding-up device, has twisting nozzle and/or thread guides movably held at perpendicular unit such that threads are guided into twisting nozzle for stopping twist with deflectors
Assembly to spin and lay bands of melt spun filaments, for the production of nonwovens, has a filament take-off and spaced guide rollers with continuous belt extensions, to gather the filaments on a sieve laying surface
Method for melt-spinning, drawing, and winding multifilament to form fully drawn yarn, involves drawing filament bundle at specific drawing speed, preparing filament bundle using preparation fluid and winding thread into package
