APPARATUS FOR DRYING TEXTILE BANDS,
YARNS, TOPS, AND THE LIKE SLIVERS Filed June 2, 1925 (liflv we? r.
Patented July 7, 1931 UNITED sra'ras PAraNr oer-ice RICHARD SCHILDE, OF HERSFELD, GERMANY APPARATUS FOR DRYING TEXTILE BANDS, YARNS, SLIYEB-S, TOPS, AND THE LIKE Application filed June 2, 1925, Serial No. 34,442, and in Germany February 21, 1925.
This invention relates to an apparatus for drying card sliver, tops and other textile material in the form of handle or threads, the characteristic feature of which is that the bands or threads are brought onto a conveyor belt which is permeable to air, carried on the said conveyor belt through a drying chamber in which air, preferably heated, passes downwardly through the material, and on leaving the drying chamber, the treated material can be at once submitted to further treatment.
Such an apparatus is more particularly suitable for the purpose of band drying, for instance for drying of card slivers, tops and the like, and has'considerable advantages over other drying apparatus for such bands.
In the drying apparatus as heretofore constructed for treating bands such as card slivers, tops and the like, the bands were guided in a freely floating manner in zig-zag fashion over guide rollers. Consequently, it was very diflicult, and took a great deal of time, to tie on any torn yarn. The yarns or bands were easily liable to get tangled, and it was very diflicult to rearrange them.
In the drying apparatus according to the invention, the bands or yarns are supported on a conveyor belt. In passing through the drying chamber, they are supported by the said conveyor belt and pressed down upon it by the air current drawn through the material and are therefore carried through the drying chamber free from tension. For this reason, any tearing and tanglin of the bands or warp yarns are precluded. should the bands or yarns however tear or tangle in spite of this it will not be necessary to remedy this until after the material leaves the drying chamher, because the torn ends are supported by 4 the conveyor belt and held fast on it by the air current. Consequently, stoppages and unnecessary waste due to the tangling of the material to be dried, will be avoided. Furthermore, it is possible, with apparatus con- 4 structed. according to this invention to Work with a more energetic-ventilation than when freely floating conveyor belts are employed, as the yarns and the like adhere to the conveyor belt and are not exposed by the air currentto any inadmissible movement, that is to say they can withstand, without being damaged, any air current.
Several constructions of such a drying apparatus are shown by way of example in the accompanying drawings in which Figure 1 shows diagrammatically in longitudinal elevation a drying apparatus for thread-like material,
Figure 2 is a plan of the apparatus shown in Figure 1,
Fig.- 3 is a diagrammatic view in longitudinal sectional elevation showing amodified construction, and
Fig. 4 is a view, similar to Fig. 3, showing a modified construction of drying apparatus.
In the construction shown in Figures 1 and 2, the bands or yarns 2 drawn from the spools 1, are taken up by the conveyor belt 3 which passes through the drying chamber 4 on rollers 5. At the end of the drying chamber, the bands or yarns are reeled on spools or the like 6 which are rotated by means of any desired drive 7. Reeds or combs 8 arrange the bands of yarns in proper position next to each other, and similar reeds or combs 9 in front of the winding spools 6 ensure the proper guiding and arrangement of the threads which then pass downwardly over rollers 10 to the wlnding spools or reels 6. The air currents, utilized for the drying, pass through the material lying on the conveyor belt 3, as indicated by the arrows 11. These air currents exercise a pressure on the material, so that it cannot get tangled. The material therefore passes without any tension through the drying chamber.
'The drying may be followed, if required,
by cooling or by renewed moistening or conditioning.
In the construction shown in Figure 3, the drying belt 3 is carried in a single section through the drying apparatus. The sliver 2 is drawn out of the container or can 1 and passes over rollers 5 which support the conveyor-belt 3, under the roller 5' which directs the threads properly through the drying chamber 4, and is suitably wound again at-6. For the purpose of lengthening the passage of the sliver 2 through the drying chamber, the rollers 5 therein are soarranged that the sliver first passes upwardly in the drying chamber, then horizontally and then passes downwardly and outwardly.
Accordingly, the air currents 11 are directed through the card sliver at right an: gles thereto in any suitable manner. From the foregoing it will be seeri that the bands, yarns and the like are conveyed through the drying chamber on a horizontal conveyor belt which is permeable to air, and that the saidbands or yarns are subjected to circular air currents which act in a perpendicular direction on the surface of the-conveyor belt from above through the bandsor yarns to the belt, so that the material being dried, when passing through the said drying chamber, is prevented from having any self movement.
