Abstract: The invention concerns a process for orienting the fiber-like macromolecules of monofilaments in a bundle via air of a certain temperature. It consists in the fact that the monofilaments are processed in any desired number of individual flow zones arranged in series with one another, which extend orthogonally to the direction of travel of the monofilaments. The advantage of the invention is that with highly accurate temperature control, the stress on the individual monofilament in the bundle is uniform and homogeneous.

Abstract: Spinning apparatus for the production of monofilament yarn includes a spinning tool having a flow channel in the form of a flattened U for providing polymer melt to a group of nozzles, the flow channel having a cross-sectional area which becomes larger, at least in an upper part thereof, in a direction of polymer melt flow therethrough.
