UNITED STATES PATERNE s'rntrnnn, or HANOVER-LINDEN, NEAR HANOVER, GERMANY.
TISSUE-UNTHREADING MEANS.
Application filed April 20, 1923. Serial No. 6333995.
To all whom it may concern:
Be it known that I, PATERNE Srniionr, a citizen of France, and a resident of Haasemannstrasse 9, in the town of I'IL11- over-Linden, near Hanover, Germany, have invented certain new and useful Improvements in Tissue-Unthreading Means, of which the following is a specification.
This invention has reference to a machine for the unthreading or disentangling of tissues and woven fabrics generally by means of revolving series of needles to which the article to be treated is fed by fluted. rollers, and it is intended to devise means for improving and facilitating the operation of machines of this kind, and to insure a more perfect operation and to prevent the tearing of the fabrics in the operation of such machine, and to further improve and perfect the unthreading or disentangling process.
In the machines of the kind referred to the material is fed to the revolving series of needles by means of two inter-engaging fluted rollers. There is the drawback, however, with these machines that there is a comparatively large distance between the nip of the two fluted rollers fort-he retaining of the material and the points of the needles, so that in accordance with the resistance presented by the material under treatment larger or smaller sized pieces are torn from the material, instead of producing the disentangling in a threadwise procedure.
In order to decrease this distance as much as possible so as to insure the seizing of the several individual threads with certain- ,ty, and to cause them to become detached with the least possible likelihood of being torn the fluted roller in accordance with my invention is so arranged as to cooperate with the cavities of the key-board like retaining means in such a manner that the material of the fabric is forced into the grooves of the delicate fluted roller rotating in such cavity, and is there retained during the entire movement, and is moved within the imnature of the tissue, so that instead of an chines in which the fabric is supported upon a grooved counter-plate and is then unthreaded by series of reciprocating needles which cause the threads employed to be slowly witlrdrawn. Such machines, however, present the inconvenience of uneconomical operation in view of the reciprocation of the needles, and in view of the difficult frequent positioning and securing of the several fabric portions; nor do they admit without alterations and withouttedious operations of the direct treating of any size and configuration of remants of fabrics, and my invention in view thereof is so designed and constructed as to obviate the various diiiiculties of the machines referred to. I
also desire to point out that themachine according to my invention is, furthermore, distinguished from the feeding means heretofore employed in connection with such machines, and consisting of a roller and conca-ved keyboardshaped retaining means, inasmuch as in such machines which are employed as boaters the feeding roller is of entirely diiferent construction, and there is no such depression with a reduced thickness of edge adjacent the operating portion, so that with heating machines of the kind referred to it is impossible to produce the results of my invention, the fabric failing to .be presented for unthreading to the coopcrating members, by which means accordmg to this invention the wlthdrawing of .the individual threads is effected systematically 1n a regular and reliable manner.
The invention will be further'explained with reference to the accompany drawing, showing by way of example one form of embodiment of the principles of the invention in Figure l in elevation, and in Figure 2 in plan view. I
The roller 1 is uniformly provided with a plurality of series of needles 2 only a part of which are shown on the drawing, and is rotated in the direction of the arrow. The fabric to be defibrated is fed by means of a feeding table 3 provided with roughenings,
substantially presenting minute teeth or needles and operating as a kind of speed regulating or braking means for the moving fabric to plurality of supporting members 3 side by side each other, and rockably mounted on a shaft The extremities of said supporting members are provided with cavities or depressions which are pressed by weights 5 or in any other suitable manner against the preferably longitudinally fluted roller 6 which serves tor the pushing forward of the fabric and is uniformly rotated for this purpose, The said trough shaped depression, as appears from the drawing, has a reduced vertically angular substantially beak-shaped freely supported term el portion adjacent the combs, so as l d to be dect' as ihrea JL, .l tached iioin t I possible to the no i '1 the thread is push (LO-0Y3 of the roller 6 i the member 1 and of may be cted, or inst '16 following inn-men on the sha the roller 6 a gear w ol '3 is mounted meshing with a gear wheel 8 which is itself mounted upon the shaft of a pulley 10 connected by a belt 11 or the like to the pulley 12. On the shaft of the said pulley 12 a conical drum 13 is mounted which is connected by a belt 14 to an inversely arranged conical drum 15 on the same shaft with the pulley 16 which re ceives movement by a belt 17 from the pulley 18 mounted on the shaft of the cylindrical roller 1. A shaft 20 with forked belt shifter 21 serves for the displacement of the belt 1 1 in accordance with a graduation 23 the arrangement of which is governed by the nature of the fabric to be unthreaded, so that one is enabled in this manner to obtain an absolutely uniform regulation of the velocity of the cylinder 1 and of the roller 6, and it is possible in this manner to either increase or reduce the feeding speed of the fabric, and the speed of rotation of the series of needles 2, so as to be sure that only the desired amount of threads may be engaged in each case by the needles 2. The graduated scale 23 may be arranged at the top portion of the machine near the feeding table 3, and the transmission of movement to the shaft 20 may be effected by bevel gear wheels, and a downwardly inclined depending shafting, not shown on the drawing and not constituting any part of my invention.
A roller 24 with brushes 25 or the like may be provided for the purpose of detaching the fibers from the needles 2. By the combination of the transversely disposed longitudinally fluted guide roller 6 with the beak-like reduced terminal portions of the pivotally yielding blocks 3 the individual threads are loosened and are securely and separately carried to the top of the beak of the members 3, and are presented to the needles of the picking roller, so that the threads are individually treated and he at entire, and tearing thereof is practically obviated. After being doifed from the needles 2, the detached threads, which for the sake of illustration may be regarded as the weft threads, though the invention nay evidently apply as well to the removal of the warps, are caused to pass between two rollers, not shown in the drawing, and thence to any suitable conveying means, carrying them to any suitable kind of containing or packing means. The remaining intersecting threads, which, for purposes of illustration, may be considered to be the warp threads, remain suspended more or less from the concaved member 8 in accordance with their le gth; tl ey are combed to some extent and loosened by the needles 2. In the case of short warp threads these drop down together with the weft-s, and are carried to the conveying means along with said wefts. In the case of fabrics being introduced into the machine at an angle to the direction of the warps or fillers, so that both the warps and the filling or weft threads are simultaneously caught by the needles, the entire material is submitted to a combing action, and the disassembling of the threads, while as thorough and e'fficient as in the case of threads in the plane of the needles, is not effected as uniformly as in the latter case which is the preferred position for the disassembling of the threads.
The invention is herein shown and described merely in its broad aspects without, however, being restricted to the particular shape and arrangement of parts shown by way of example and as a matter of explanation, but changes and modifications may occur to suit existing conditions and the convenience of the operator, and without deviating from the spirit of my invention as expressed in the claims, hereunto appended.
I claim 1.
