Definitions

  • the present invention relates to an apparatus for processing textiles.
  • the present invention relates to an apparatus for processing filaments, such as those formed from synthetic materials.
  • Newly spun filaments of the above type must be processed just after the spinning thereof by being passed through several baths of treating liquids of difiercnt types. These filaments are usually guided in groups through the baths, and the movement of the filaments through the bath liquid creates a turbulence in the latter which produces an undesirable bending of the" filaments and at the same time a spreading of the same so that short filament portions extend laterally from the filaments. It has been found that sometimes the bending of the filaments may be as much as 30mm., and the spreading of the fibers produces an undesirable clinging of the filaments to each other. Also, the bending of the filaments is particularly undesirable since it very often causes the filaments to slip from the guide rolls.
  • One of the objects of the present invention is to overcome the above disadvantages by providing an apparatus which prevents the creation of a turbulence in the bath liquid through which a group of filaments passes.
  • a further object of the present invention is toprovide an apparatus, for preventing turbulence, which is of an extremely simple and rugged construction.
  • the present invention consists of an apparatus for treating textile filaments, this apparatus including a bath and apair of spaced guide rolls associated with the bath for guiding a group of filaments therethrough.
  • a pair of opposite elongated plates are spaced from each other, located between the rolls, and are arranged along a path extending from one of the rolls to the other of the rolls so that when a group of filaments are guided between the plates the latterwill prevent a turbulence in the bath liquid between the plates and will thereby prevent bending and spreading of the filaments.
  • a floor portion extends between the plates and is connected to the lower edges thereof to prevent a turbulence in the liquid at the underside of the group of filaments passing through the bath.
  • Fig. 1 is a diagrammatic top plan view of a known treating bath and illustrates the turbulence of a liquid therein;
  • Fig. 2 is a diagrammatic side elevational view of an apparatus constructed in accordance with the present invention.
  • Fig. 3 is a partly diagrammatic top plan view of the structure of Fig. 2;
  • Fig. 7 is a diagrammatic side elevational of still another embodiment of the present invention.
  • Fig. 8 is a top plan view of a further variation of the structure of the present invention.
  • a conventional treating bath is shown in Fig. l where the guide rolls 1 and 2 are associated with the bath for guiding a group of filaments therethrough in the direction shown by the arrow at the lower part of Fig. 1.
  • the filaments produce a turbulence in the liquid of the bath which causes the bath liquid to circulate in the direction of the dotted lines 3 and arrows thereon shown in Fig. 1.
  • this turbulence is very undesirable because it produces undesirable bends in the filaments and furthermore causes the filament fibers to spread so that short fine filament portions extend from the filaments and cause the latter to undesirably cling to each other.
  • Figs. 2- and 3 show one possible construction for overcoming the disadvantages of the" conventional structure illustrated in Fig. 1.
  • a pair of plates 4 are arranged in the bath 1 4 in spaced relation to each other and extending between the guide rolls 1 and 2 which guide the filaments to the left, as viewed in Figs. 2 and 3, the roll 1 being an entrance roll for introducing the filaments to the bath and the roll 2 being a discharge roll for discharging the filaments from the bath.
  • the plates 4 are located fairly closeto the rolls' 1 and to the group of filaments and extend above the level 5 of the liquid in the bath, and these plates 4 'efijectively prevent a turbulence of the type shown in Fig. 1.
  • the plates 4 are interconnected by a floor membet 7 which extends between the plates 4 and is connected to the bot-tom edges thereof, this floor member 7' being located close to the underside of the group of filaments so as. to prevent any turbulence in the bath liquid at the underside of the group of filaments passing" through the bath;
  • Fig. 3 illustrates one possible supporting structure which includes. the straps 11 fixed to and extending from the plates 4 and engaging opposite edges of the bath so as to maintain the structure 4, 7 in the position shown;
  • Fig. 4 illustrates a variation of the structure of the invention according to which: the floor part 7' is inclined so that its'right end, as viewed in Fig. 4,. is more distant from the entrance roll 1 than its left end isdistant from the discharge roll 2, and thus the floor 7' graduallyapproaches the filaments as they proceed throughthebath. to very effectively prevent turbulence at the dis! charge roll 2.
  • the side walls24 of the-embodi ment of Fig. 4 are each formed at their opposite ends with cutouts 12 into which the rollsl and 2' respectively extend, so that turbulence of the bath liquid is efiectively eliminated even at 'the region of the rolls 1 and 2;
  • Figs. 5 and 5a illustrate a variation according to which the discharge roll 2 is formed with annular grooves 13,. respectively adjacent its opposite ends, and the troughshaped structure 4",.7 extends into these grooves to reduce turbulence in the region of the discharge roll 2 in. way;
  • Fig; 6 illust'ratesa furthervariation' accordi'ngto whieh 3 the side plates 9 extend to points opposite the end faces of the guide rolls so that the turbulence of the liquid can be "reatly reduced in this way.
  • Fig. 7 illustrates a structure corresponding in all respects to that of Figs. 2 and 3except that the floor portion 7" of the trough-shaped structure is downwardly curved its opposite ends, as shown in Fig. 7, so as to produce a more laminar flow of the bath liquid in the region of the entrance and exit rolls. 7
  • Fig. 8 is a top plan view of a structure which also corresponds to that of Figs. 2 and 3, the structure ll being difierent in that the door portion 7 of the troughshaped structure is approximately 3 of the length of the side plates 4 and is located adjacent to the discharge roll 2.
  • a great saving of the material of the trough-shaped structure is effected wit r g any increase in the turbulence of the bath h the portions of the filaments approaching the discharge roll 2, where turbulence is most undesirable.
  • trough-shaped structure may be mounted on the bath in the same way "as illustrated in Fig. 3, and of course other supporting structures are possible without departing from the scope of the invention.
  • the guide rolls shown in the various embodiments may be mounted on hangers as schematically shown in Figs. 5 and 6 or any other supporting structure may be used for supporting the rolls.
  • the arrows 6 in Fig. 3 illustrate how the treating liquid passing through the trough-shaped structure 4, 'i' circulates about the trough-shaped structure from the discharge end of the bath to the entrance thereof.
