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 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.

Coating apparatus

This invention relates to a process for the continuous manufacture of smooth or textured multifilament yarns from synthetic thermoplastic high molecular weight polymers by the spin stretching or spin stretch texturing processes, wherein the unstretched multifilament yarn is passed from the spinning machine to the stretching or stretch texturing machine through tubes made of metal, plastics or glass, although other materials may also be used, e.g. ceramics.
