Y., a corporation of-Delawsre Application January s, 1933, semina. In Austria 4March 5, 1932 v s claims.
The invention comprises a process and apparatus for the continuous manufacture of artificial filaments. I
It has already been proposed to subject the artificial filament to the precipitation and after treatment while being placed upon endless ribbons or in grooves, in order to be iinally dried and wound upon take-up rollers. This process has the disadvantage that it requires much speed; it is, therefore, not applicable if an economical spinning speed is employed. i
It has been suggested also that the artificial filament 'ce guided in a helical path over rollers or `discs, whereby grooved rollers or guide bars were used in order to maintain the helical path. 'These processes also require a great deal of skill and., more particularly, considerable time until the necessary number of windings are placed around the treating roller. This disadvantage is not only encountered during the start of th`e spinning process but also on the occasion of thread breaks. Consequently, the process required a comparatively large number of operators and could, therefore, not gain popularity in the trade.
It must also be considered that at an economical spinning speed, a very large number of windquire the guidance of the filament in numerous windings in order to obtain a sumclent treatment of the thread.
The present invention is based upon the new idea that it is possible to obtain a much better treatment through the employment of two ordinary rotatable rollers, under certain conmtions, whereby the filament is automatically advanced. The freshly spun filament is guided in a helical path over one or more pairs of rollers which rotate in the same direction as the filament advances. The shafts of the rollers are positioned at an angle to each other. The lament is treated during its movement on the rollers. The filament is first of all placed upon the rollers in the form of a closed loop. The loop is suitably formed through a manifold winding of the thread, whereby the different windings touch one another. The windings of the thread adhere to one another due to their moisture.
After several turns of the rollers, it is noticed that the loop of thread slowly travels along the stasi:
vintersection of the shaft independent oi' the direction of rotation of the rollers. If rollers are employed which are arranged at an angle to one another horizontally, the direction of advance of thread depends upon the direction of rotation of the rollers. Although the advance of thread by the employment ofthe rst mentioned rollers takes place while the thread is passing through the air, i. e., between the rollers, it mainly takes place aslong as the filament is in contact with the' rollers. if the second mentioned type of rollers are employed.
It is important during this movement of the thread that the lament temporarily revolves on the roller vclue toits advance. By this means .the
filament is not only brought in contact with the liquid at all points, but also an especially intensive exchange of liquid is effected through the intermittent compression and' loosening ofthe fila-" ment, which otherwise is only Possible through diffusion. l v
At an automatic advance of thread on the roll' ers and a comparative small number of thread windings, the present process makes itPOSible to obtain a suiiicient wet treatment and, particularly, a complete washing process, without any' chemical impurities remaining in the nlament. By this means it is possible to keep the dimensionsof the washing devices. within suitable limits in case a high spinning speed is applied.
Moreover, it is possible kto provide a series o! wet treatments, whereby the filament maylalso be bleached, dyed or sized, if desired.
Further advantages may be obtained ifseveral filaments from diierent adjacent spinnerettes'are The wet treatment of the filament takes place' through the rotation of one roller or of both rollers in the necessary baths. It is,'however, suiiicient if the rollers are sprayed with the liquids. The best results will be obtained it the entire sur-
