Definitions

  • each zone of the spinning cell orchamber is provided with orificesfor the admission and discharge of air, so that the circulation of the air and vapors of solvent in each of the zones is entirely independent of the circulation in the other zones and without appreciable infiuence on such circulation.
  • the air which has been admitted into and discharged from one zone may enter a second zone and, on
  • V to add to said air, ⁇ at any desired point'of'its passage, vapors or gases of suitable nature for exercising any desired phy- ⁇ sical, chemical or other action on the thread.
  • Fig. l is a vertical section through a chamber provided with a horizontal diaphragm *obstructing the whole cross section of said chamber;
  • Fig. 2 represents, also in vertical" section, a chamber provided with an oblique diaphragm;
  • Figs. 3 to 5 are diagrams showing means enabling the same air to be utilized for the circulation in each zone of the spinningchamber.

  • G the orifice through which the thread passes out
  • ,-MN represents a diaphragm in the spinning cell or chamber.
  • vthe diaphragm MN is horizontal andextends between the two walls AC and BD of the spinning cell or chamber, so as to divide the latter into two distinct superimposed zones or compartments, the thread H passing through an orifice Z in the diaphragm. ⁇
  • the upper compartment which contains the spinT ning nozzle F and is rovided with orifices E for the admission o cold air, is also provided with an Vaspiration orifice J, pierced in the wall.
  • BD of the cell "I-Iot air enters aspiration is effected through a convenientl number of orifices, such as L, also provided in the wall BD.
  • the diaphragm MN is oblique and the. aspira'- tion, at J, of the' air enterinor the upper zone through thev orifices E, is eected by means of a tube J1,"which rests on the diaphragm and the mouth J 2 of said tube is situated at a suitable distance from the thread H.

  • the upper compartment of the cell receives, at E, cold air which issues from said compartment at J, and passes through a heating apparatus V of any kind, to enter the lower compartment, at a suitable temperature, by way of the orifice K, from which compartment it issues, laden with vapors of .sol-
  • the air which has previously been raised to the desired-temperature by any convenient means, is ladmitted into the lower Acompartment of the cell through the orifice or passage K, and issues from said compartment by wayof the tube L.
