'PAUL GREVE, oE LINDAU, HARZ, GERMANY.
TWINE POLISHING ANI) DRYING MACHINE.
Application filed April 22, 1924. Serial No. 708,194.
To all 'whom t may concern:
Be it known that I, PAUL GREVE, a citizen of Germany, and a resident of house Number 220 in the town of Lindau, Harz, Germany, have invented certain new and useful Improvements in Twine Polishing and Drying Machines, of which the following is a specification.
This invention has reference to a comb-ination of polishing and drying means for twines, coids and the like, and it is articularly intended to provide means for increasing and improving the output and the character of the product obtained, and to facilitate the general operation and to simplify the construction of devices of the kind referred to. Broadly speaking the invention is distinguished from the previous art among ot er important features by the fact that the drying is effected by means of an unheated c drying cylinder in accordance with my invention serving chiefly as a guiding means, while the drying proper is effected by hot air surrounding the twine, string, cord or the like before, during and after its passage over said cylinder; and in a preferred form of construction I may arrangel the drying means in a separate enclosure and not containing the polishing or smoothing means for thethreads whichare usually coated or Means are also provided in the practice of my invention to cause the current of drying air to circulate through said drying room and over and around the threads several times, while the polishing or smoothing operation may be conducted outside of said drying room in the usual manner by conducting the threads over and between a plurality of rotating polishing rollers or the like. Y
The carrying out of the polishing or smoothing and of the drying operation in two separate enclosures is also an important feature of my invention, inasmuch as according to previous methods these operations have been carried out in one and the same enclosure, so that the exudations and vapors from the size greatly interfered with the success of the drying process, while the drying air caused a partial premature solidification of the size entailing the liability of breaking of the threads. Of such previous devices I may mention cursorily the alterlpassing of the twine threads through a y of paste and over felt-coated fricnate supp ylinder and by hot air, the usualv tion and guiding rollers while according to other suggestions the twine was guided over a plurality of fluted and moistening rollers,
and subsequently through a heated container in which grouped around a heater. The drying operation was ordinarily effected heretofore by means of a plurality of adjacently arranged heated drying rollers between which vanes or the like were arranged, in order to impart a certain direction to the drying air, or according to another suggestion, a single interiorly heated drying cylinder coo erating with a polishing brush mounted in the proximity thereof has been employed. By employing an unheated drying cylinder according to my invention the fiber of the thread is preserved and saved from burning, and by this means and by the separation of the drying and polishingV or smoothing means the entire operation may be -more easily conducted and controlled, and the drying efficiency is increased by the repeated circulation of the drying air out of contact with the polishing means, the radiation of heat is overcome, and the operation is facilitated in view of the fact that the several steps may be controlled independently, and the polishing or smoothing rollers bea series of polishing rollers were mg arranged outside of the drying room are accessible from both sides.
The invention is illustrated on the accompanying drawing in two forms of embodiment of the principles thereof by way of example, and in a conventional manner m Figures 1 and 2 in part side view and with parts in section.
In the drawings z-a are the polishing or smoothing rollers, b and cV are the guiding and circulating reels, ci is a drum with closed shell and surrounded by the casing f, and not adapted to'be heated. e indicates p assages or channels for the air communicating with thebellows g and containing the heating means h. The form of construction according to Figure 2 is chiefly distinguished from Figure 1 by the fact thatthe heater or radiator is mounted above the polishing rollers. In both' forms of execution of the invention the drying room is closed by the Wall m which only leaves the narrow holes or slots for the passage of the threads which, for .the drying operation, are preferably arranged `in one and the same plane. s
The method of operation of the device is substantially as follows: A plurality of of the threads, are con ucted during the polishing or smoothing operation simultaneously into the dryin lchamber and over thedruni d." Upon their escape from the dryin passe chamber -the threads are again are then caused to pass again through the 4Figure 2 the hot drying chamber. This procedure may be repeated several times according to the number ,of threads introduced and depending upon the width of the machine, and may be carried on a dozen times or more. i While the threads are passed around the drum d they are acted upon by a current of hot air furnished by the bellows g or in any other manner, the said air current circulati continuously around the drum d, as in icated bythe arrows, thereby the threads. Fresh air may-be introduced into the channel eor to 'thebellows at any suitable point and may be controlled in the usual manner. The drying chamber is preferably protected from loss of heat by heat insulating material or by several outer coat- 1n s.
In the form of -construction according to air, after having passed around the drum d and after having acted upon the threads during their entire passage through the chamber, is forcibly aspirated at a point k near the wall m, so'that no hot air is likely to be lost at the points of entrance and discharge z' of the threads. yFrom Figure 2 it also appears that the passage or channel e is reduced in sectional areas at the parts where the threads are supported upon the larg portion of the casing the velocity'v ofthe eating airis increased. In that portion of the casing' e in which the threads are freely exposed they are bathed on all sides by the hot air, and before the threads are allowed to escape, the air issucked off, is conducted throughthe bellows, fan or the like g and throu h the heating vdevice and is then again intro uced intothe vdrying' chamber after only a short outside passa e. The heating means may beV of `any suita and it may also be arranged, if desired, in drying chamber itself. The arrows p in Figure 2 indicate the way of the heating medium for heating the heaterl h. In Figure 1 there is a substantially fork-shaped channel e for the passage of the hotl air so that the streamsof incoming and outiowing air may not interfere with each other. In Figure 2 the air is conducted by the narrow passage e into closev proximity Awith the` drumd.-. l I
The threads, for instance, may be intro duced at: the lower left hand side of the two li res, and in. a., parallel direction, as indicated by'the arrow.) InFigurel they are between the polishing rollers a, andl thoroughly bathing e drum d, so that in this le kind desired,
assed directly into the chamber f, while f 1n Figure 2 they are first conducted up,- waids between the polishing rollers.` In this ligure they are then conducted around the upper rollersnand reel Z) to the right andy around the drum d. Some of the threads arevthen again passed downwards between the rollers and around the lower roll or reel c land through the slot i. B this means the threads are passed twice t ro'ugh the polishing device. 4 In accordance therewith, and
'bellows' or. fan g over or between the heater pipes h, and into the room f' and around the drum d, whereupon the air is sucked 0H at 1:.
Among the several advantages of the new arrangement I may vmention the following Therthreads to be polished are not injured, inasmuch as they are prevented from coming in contact with steam heated surfaces or steam cylinders which would entail the danger of superdrying,` overheat-ing and burning, particularly in case of' an unavoidable interruption of operation; hence, the new method and means there is no liability of sticking of the sized threads, and in contradistinction to the machines with steam heated drying cylinders the tension -of the threads may be increased to the maximum, so as to produce thevery best degree ofipolish. There is the further advantage over steam heated drying cylinders that the drying surface is increased for a multiple thereof, and the drying operation is particularly efficient on account of the strong current of air. Then, the heat is utilized in y.the most efficient and economical manner,
inasmuch as byl the circulation ofthe air the eater part t ereof is always re-conducted into'the system, while, in view ofthe insulation of the drying chamber, the liability of loss of heat is reduced'to a minimum; nor is there any radiation of strong heat into the working room, which is unavoidable in the case of steam heated drying cylinders.
It thereforel appears that with the device according to my invention lower temperatures may be used in the drying process than usually employed heretofore, so that a great economy in fueland steam may be effected, while at the same time a highly -superior polishing effect is produced, such as is not produced by the instrumentalitie's heretofore sug ested, as far as I am aware., Generally a' rymg temperature of, say,
from"35 to 40 degrees centigrade will be found satisfactory and sufficient. By diswith l ing the drum d with projections or ri posing the smoothing and polishing rollers at the outside of the air chamber the scraping and rubbing off of the size from the cords or threads and the thereby resulting clogging up and soiling of the air chamber and of the drum d are prevented\ and the polish ismore uniform and permanent than in the case of the' rollers acting upon the size in its hottest condition. My invention is also particularly distinguished by the fact that in its most preferred embodiment the Warm drying .air is 'caused to pass in the same direction as the threads or ycords by which means roughening of the fibers and.
scorching thereof is prevented, which is liable to occur, when the nearly dried and hot threads meet the warm current of air at its highest temperature. In my invention the Warm air travels in the same direction as the threads or cords, so that the b warm air current is cooled oil' gradually as it flows alongthe threads, and the dried thread is surrounded by a .comparatively cooled current of air, and is prevented from becoming ruptured in leaving the air chamber by the sudden drop of temperature which it would have to undergo, in case of the air current flowing in the o posite direction, and there is the further avantage that ythe air current\in m invention by its codirectional course willI lay down and smooth the fibers, instead of blowing them up and roughening them. Bg' arranging the polishing rollers outside o the air chambers any occurring ruptures of threads may be easily remedied, while the staggered relation of the rollers prevents jamming and irregularity of pressure.
It is obvious that other modifications are possible within the scope of my invention, t0 better adapt the same to varying conditions of application, and without deviating from the spiritof the invention, as set forth in the claims hereunto appended.
The invention may be modified by rovids 1, 'so that the twine or cord to be dried and polished may be more easily surrounded on all sides by the hot air. Instead of air equivalent inert gases or fluids may be used.
