This invention relates to an apparatus for applying a thin layer of liquid systems to fibers, threads or sheets which are moved uniformly in a linear direction which comprises continuously foaming the liquid system and bringing the threads, fibers or sheets into contact with the foamed system by a one-way process.

Apparatus for coating fibers, threads and sheets

The invention relates to a nozzle device for texturizing filament yarns of synthetic, high molecular weight substances by means of a hot medium comprising heated gases or vapors, comprising three chambers arranged on after another, a first chamber through which the hot medium flows into a second chamber, the yarn being drawn into the second chamber at an angle to the direction of flow of the gaseous medium, the yarn being heated by the gaseous medium in the second chamber, and a third chamber in which the thread is compressed with the formation of plugs, the compression chamber being formed of a plurality of elastically flexible rods which are arranged on the surface of a right circular cylinder or a right circular truncated cone and fixed at one end on the end of the second chamber, the rods being of two different lengths.

Nozzle device for the production of texturized filament yarns

The invention is related to a process for the quantitative application of liquid systems in a thin layer to natural or synthetic fibres or filaments travelling uniformly along a linear path by the one-way technique using a forced-dosage unit, distinguished by the fact that fibres or filaments are guided past at least one slot which is either curved or provided with partial curves, and are brought into contact with an optionally foamed liquid issuing from the slot.
