Definitions

  • the present invention relates to the treatment of threads and more particularly to a liquid aftertreatment of a sheet or warp of closely spaced parallel threads passing in a horizontal or substantially horizontal plane through an open receptacle filled with a suitable liquid,
  • This invention represents a further development over that described and claimed in the copending Schrenk application Serial No. 292,920, filed June 11, 1952, now Patent No. 2,674,113, issued April 6, .1954, and assigned to the same assignee as the present application.
  • this invention relates to a device for the continuous treatment with liquids of a number of closely spaced threads running in an almost horizontal plane, in which the threads are led along the undersides of guide rollers located at the beginning and end of a trough at a vdistance of some millimeters, e. g., 3-7 mm., below the liquid level therein.
  • the apparatus com'prises a trough or receptacle having guide rollers at the beginning "and end of the receptacle, and an inlet and an outlet for the treating liquid arranged in such a way that the liquid level in the receptacle lies at a distance of-some millimeters, e. g., 37 -mm., above the undersideof the guide rollers.
  • a plate is provided having means for keeping the plate at a distance of some millimeters, e. g., 1-5 mm, from the common tangent plane through the undersides of the guide rollers.
  • the sides of at least part of the plate may also be provided with thread guiding edges. It is also desirable to position the plate within the receptacle at such a slope that the'threads 'near the feed roller are at a distance of 1-2 mm. greater from the plate than are the threads near the delivery roller.
  • the length of the plate is such that the plate terminates before the vertical tangent plane at the front side of the delivery roller.
  • the plate extends beyond the deliveryrolle'r and there is curved downwardly, this curvature beginning before or at the line intersecting the vertical tangent plane at the fron't side of the. delivery roller.
  • the curvature be circular andthat the radius of the circle be
  • the means for setting the plate in the trough is additionally adapted so as to allow a downward, temporary displacement of the plates, at the ends to insure adequate clearance for the guide rollers as they are swung into operative positio about their pivots.
  • the plate may be placed in the receptacle in various Ways. According to one favorable embodiment the plate is kept in position in the liquid-filled receptacle by means of floating bodies. Preferably, one or more air chambers are then employed as floating bodies.
  • the plate In order to facilitate the temporary movement of the plate at the ends when pivoted guide rollers are employed, it is desirable to support the plate at the centers of both sides by means of trunnions fitting in the side Walls of the trough, so that the plate may revolve about this sup- P I g
  • its four corners may be provided, at or near the ends of the plate, with projections extending longitudinally and kept in place-against the lower side of the ends of the "guide rollers or against plates connected at those points with the rollers.
  • Figure 1 shows a top view of one embodiment of the device according to this invention
  • Figure 2 shows a vertical sectional view of the device shown in Figure 1, andalso swingable or pivoted guide rollers which for simplicity are not shown in Figure 1';'
  • Figure 3 shows a second embodiment of the invention, representing only apart of the trough near the delivery roller
  • Figure 4 shows, in the same; manner as Figure 3, a third embodiment
  • Figure 5 shows, in the same manner as Figure 3, a fourth embodiment
  • Figure 6 shows a further improvement of the particular embodiment shown in Figure 5.
  • Figure 7 shows a detail of one end of a guide roller useful for keeping the plate in place in the receptacle.
  • FIG. 1 denotes an open treating receptacle through which flows the treating liquid 2.
  • the level of the treating liquid is, as indicated in Figure 2, determined by the position of the outlet 3 of the receptacle.
  • the liquid inlet may be accomplished in any conventional manner, not shown.
  • the guide rollers 4 and 5 along the lower sides of which a number of threads 6 (constituting a flat sheet or warp of threads) are led. At a distance of some millimeters apart, the threads, which may number 30, 60, 100, or more, are led through the treating liquid. If no special precautions are taken, there arise in the receptacle due to the draw of the rapidly moving threads in the treating liquid numerous backand cross-currents which exert an irregular, varying, and detrimental influence under, beside, and over the threads.
  • the sides of the receptacle itself may serve as well; in such case care should be taken that the threads are caused to occupy the entire width of the trough to a distance of 3-7 mm. from either side.
  • Figures 3 4, and 6, parts which correspond to parts shown in Figures 1 and 2 are designated by the same numeral with a distinguishing alphabetical suflix. It is understood that the general assembly of Figures 1 and 2 is applicable to Figures 3 to 6, inclusive, which illustrate different types of plates.
  • Figure 3 shows an embodiment in accordancewith which the plate 7a is straight over its whole length, and rounded off at the end.
  • Figure 4 shows an embodiment with a similar plate 712 of which the rounded end is thicker than the body of the plate, in order to promote the return flow of liquid under the plate.
  • each thread floats like a suspension-bridge over the liquid level in the wave-trough proper, whereas a dam-like veil of liquid is formed from each thread in this wave-trough.
  • the means for adjusting the position of the plate in the receptacle be so arranged as to allow of a downward, temporary displacement of the plate and its ends.
  • the auxiliary rollers 10 and 11 are outside the liquid during normal operation, whilst the rollers 4 and 5 guide the threads through the liquid.
  • the guide rollers 4 and 5 have bearings at the ends of two levers connected at the other ends with the pivots 12 and 13, respectively.
  • the auxiliary rollers 10 and 11 have bearings between two levers also connected with the pivots 12 and 13, respectively, and set at an angle with the levers of rollers 4 and 5.
  • This thread guiding arrangement has great practical advantages as the threads are easily threaded in and the guide rollers may be cleaned very easily without interruption of the overall process.
  • FIG. 2 shows the detail of such a floating body, consisting of an air chamber 14 disposed below the flat surface of the plate 7.
  • the plate in the treating liquid obtains the necessary upward pressure due to the buoyancy created by the air chamber.
  • trunnions 15 are provided which slide in slots 16 in the sides of the receptacle 1 (see Figure l), and may revolve or pivot in them. In this way, the plate 7 may move up and down in the liquid, and at the same time, may pivot by means of the trunnions 15 in the slots 16.
  • the ends of the plates thus may be caused to make a downward, temporary movement to provide clearance or additional clearance for the swinging or pivoted guide rollers.
  • the plate 7 may also be provided with other lifting devices, by which, with the aid of adjusting devices, the distance from the plate to the bed formed by the warp of threads undergoing treatment may be adjusted, and which may press the plate upwardly against the rollers.
  • lifting devices springs, e. g., tension springs, may be used which press the plate upwards.
  • floating bodies and in particular the air chambers described above have been most satisfactory.
  • Other floating bodies resistant to the treating liquid, e. g. those made of cork, are also serviceable.
  • these like the plate itself, may be made of metal, plastic or other suitable material depending upon the nature of the treating liquid.
  • extensions 17 In order to assist in keeping the plate 7 properly in place, it may be provided at the four corners with extensions 17 (see Figure 1). These extensions or protrusions 17 may rest against bent plates 18 (see Figure 7) mounted near the ends of the pivoted guide rollers.
  • the plates 18 are attached to or supported by the bearings of the guide rollers.
  • a similar construction may be employed at the trunnions by which the guide rollers then are mounted in the sides of the receptacle.
  • Apparatus for the liquid treatment of a warp of moving threads comprising an open receptacle for containing a liquid, thread guiding rollers including a feed roller and a delivery roller disposed in said receptacle and rotatable about horizontal axes, a plate disposed below the normal level of liquid in the receptacle and defining two regions communicating with each other in the upper one of which the warp of threads passes during the liquid treatment, and means for mounting said plate, for vertical adjustment and for tilting about a horizontal axis parallel to the axes of the thread guiding rollers, and buoyant means in supporting relation to said plate to support the same in the receptacle when the latter is provided with liquid the depth of liquid in said receptacle determining the vertical position of said plate.
  • At least one liquid flow guide blade is located adjacent the rounded ends of said plate, whereby to assist in circulating the treating liquid in said open receptacle.
  • the means mounting said plate comprises trunnions extending from the center of both sides thereof about which trunnions said plate may revolve, and means defining slots in opposite side walls of said receptacle, said trunnions engaging in said slots in the side walls of said open receptacle.
