APPARATUS FOR TREATING YARN, THREAD, RIBBONS AND THE LIKE ELONGATED MATERIAL CAPABLE OF BEING STRETCHED Filed Dec. 10, 1959 United States The present invention relates to apparatus for treating, as by washing, drying, drawing, shrinking, fixing, etc. fiber ribbons or continuous filament yarns, hereinafter referred to as cables or spinning cables (that is, uncut filament yarns or cables as they are discharged from the spinning nozzle) particularly fully synthetic material.
Washing units are used for washing, drying, drawing and fixing endless ribbons of fibrous material wherein the ribbons must be first threaded by hand and thereafter are conducted by hand to drawing rolls. These drawing rolls are arranged either in heated chambers kept at very high temperatures or the rolls are heated from the inside with steam and the ribbons are thus brought to the temperatures necessary for a drawing operation.
It is very difiicult to feed endless ribbons or filament yarns to these rolls into hot chambers.
Since the rolls tend to wind and bulge, it is very difiicult, due to the high temperatures, to keep the internally heated rolls clean. Subsequently all fibers are drawn or elongated by dual, triple or quintuple delivery units. After drawing, the fibrous threads are fixed at high temperature.
Each time that the apparatus is started, all these operations must be performed by hand and any additional ribbon, that is to be supplied later, must also be introduced by hand into all units or machines. These operations are very time consuming and, to a great extent, jeopardize the continuous operation of the fiber trains. Since these fiber trains must work for Weeks in continuous operation without interruption, any disturbance and any stoppage results in high expenses.
It is therefore an object of the present invention to provide means conducive to an automatic and controlled performance of all the aforesaid operations.
The cables are introduced or fed at the inlet to washbath means and travel completely automatically through the washing apparatus and the drier.
In order to be able to also make the drawing process automatic, special screen drums having special drives are provided. For this purpose a heating zone is attached to the drier. The material to be processed is conducted over screen drums and brought to the drawing drums, completely and uniformly heated by air current.
Pursuant to another object of the present invention, one-sided heating of the fiber ribbons, as was the case with prior art internally heated drawing rolls, is avoided whereby the quality of the materials to be drawn is substantially improved.
In this connection, it is a further object to provide means obviating the necessity to overheat the outer surfaces of the fiber ribbons before the desired temperature is attained in the interior of the fiber ribbons.
Due to'this measure it is possible to automatize the entire operation, because the ribbons are now automatically taken over by the drums.
Since great stresses develop during the drawing operation, it is necessary to increase the thickness of the screen drums and particularly to smooth the surfaces thereof. All drives for these drums must be variable and they must be sturdy.
Provision is made for a drawing compartment which Patented May 8, 1962 is followed by a cooling compartment. The thermoplastic fibrous material, which is rendered plastic in the drawing compartment, is returned to the solid state in the cooling compartment. After the drawing operation the fibers are again heated, while stress-free, and are fixed. These operations are also carried out on screen drums and the fibers can be applied thereto in a completely relaxed and stress-free condition, due to regulation of the speed of the drums.
The function of the fixing operation is to keep the fibers in their required form. The danger that they will contract again is thereby obviated. The difference between drawing and fixing is that in drawing the fibers are subjected to stress and their diameters are reduced by drawing to about one-fifth of normal. However, in the fixing operation the fiber is heated in a stress-free condition.
It is another object of the present invention to provide means resulting in the completely automatic guidance of the fiber ribbons or filament yarns, without any winding during the drawing process.
It is a further object of the present invention to provide means afiording drawing, shrinking, fixing of the fibers with temperatures which can be kept much lower than in prior art heated rolls. This results in a greater protection of the fibers.
The drums can also have a grooved surface provided with perforations. Individual drums can be equipped with a free-wheeling system to adjust them to a velocity increase caused by the drawing operation. It is possible to disconnect the free-wheeling system.
These and other objects of the invention will become further apparent from the following detailed description, reference being made to the accompanying drawings, showing preferred embodiments of the invention.
In the drawings which illustrate the best mode presently contemplated for carrying out the invention:
FIG. 1 is a schematic view in elevation, partly in section, of an apparatus pursuant to the present invention.
FIG. 2 is a top plan view of the apparatus, with a portion thereof broken away for purposes of clarity.
- Referring now to the drawings in detail, there is shown a somewhat schematic representation of an apparatus 30, pursuant to the present invention, for treating fibrous material such as, for example, continuos filament yarns, to effect washing, drying, drawing and shrinking thereof in a tandem arrangement.
The fibrous material 9, which is to be treated by the apparatus of the present invention is introduced thereinto at the inlet E, as shown by the arrow 31.
At the inlet E the material 9 is engaged initially by a pair of companion feed rolls 11 from which it is fed to an endless belt conveyor device 2 which delivers the material to a wash bath 4a. The wash bath 4a consists of screen drum 3 operable in a wash trough 4 provided with a siutable wash fluid.
A pair of cooperating squeeze rollers 6-6 are located behind the wash bath 4a, in the direction of travel of the material 9. An endless belt conveyor 5 carries the material from the wash bath 4a to the squeeze rollers which remove the wash liquid from the material.
From the squeeze rollers 6, the material is conducted over a duckboard or latticework 7to a drying apparatus 30 by means of deflecting feed rolls 88, the inlet to said apparatus being indicated at 33. The apparatus 30 is provided with a housing 18 which is divided by partitions 19 into four zones or compartments designated 14, 15, i6 and 17, respectively.
The partitions. are provided with central slots as so that the material 9 can pass therethrough. The compartment or chamber 14 constitutes a heating chamber, suitable aosaese means (not illustrated) being provided to effect a heated air current flow therein.
A pair of screen or perforated drums 1t} and a is provided in compartment 14. The material 9 is carried under drum 10 and over drum 10a to effect the drying ofthe material by hot air current flow.
The compartment comprises a drawing zone having the screen or perforated drums 11 and 11a. The material passes through the slot 34 of the partition 19 common to chambers 14 and 15 passing under drum 1i and over drum 110.
During the drawing operation, which is accomplished between drums 11 and 11a, the heated fibers are stretched and the diameter is reduced to substantially one-fifth of the prior diameter. This requires thick-wall drums having a particularly smooth surface. The drums 11-11a have a-variable drive so that their relative rotational speeds can be regulated. Due to the arrangement of the screen drums 10-10a and 1111a, the material 9 can be both dried and heated uniformly from the inside and the outside, warm air passing through the perforated or screen drums.
From. the drawing compartment 15, the material passes into the cooling compartment 16 through the corresponding slot 34 in the partition 19 common to the drawing and cooling compartments. In the cooling compartment 16, the air temperature is lower than in the preceding cornpartments so that the material, which had been rendered thermoplastic in zones 14 and 15, again reverts in compartment 16 to a solid or non-plastic state or condition. The material thereafter passes into the last chamber 17 which is a fixing or shrinking zone. Here the fibers are fixed in their required form. This is effected by heating the fibers, in a stress-free condition, as they pass under and over the screen drums 1313 of the shrinking chamber 17.
The drive for all the screen drums is elfected by a motor 21 which drives a transmission shaft 22 journalled in a support or bracket 24- associated with each drum. A variable speed transmission 25, provided for each drum, permits adjustment of the speed of rotation thereof.
Provision is also made for an exhaust fan for each drum.
As the material leaves the fixing chamber 17, it moves through the outlet A, in the direction of arrow 134 by discharge rolls 26 which move it onto an endless belt conveyor 27.
If desired, companion take-up and drawing rolls may be interposed between the rolls 3 and 6 to keep the material under any desired tension.
Various changes and modifications may be made without departing from the spirit and scope of the present invention and it is intended that such obvious changes and modifications be embraced by the annexed claims.
