(Cl. 242-355) to the dong and threading-in more particularly to the threadmachines with large numbers of This invention relates of winding machines and ing-in of cone winding runnings ends.
In the more modern continuous spinning systems, large numbers of finished yarns are dried simultaneously in These continuously running ends Doiling a collecting device which is being supplied by a continuously running end is always diicult,
Figure 1 is a view in side elevation of a coning machine and an ambulantwaste and linished cone receiving device both modified according to the'vpresent invention;
Figure 2 isa front view of the coning machine of Figure l;

Figure 5 is a top plan View of a typical plant arrangement according to the present invention; and
Figure 6 is an enlarged View in side elevation of the suction device and thread guide shown in Figure 1.
Referring now to the drawings in greater detail, it will be noted that there is shown, in Figures 1 and 2, a basically conventional cone winding machine equipped with certain accessory mechanisms according to the present It is also to be understood that the coning machine shown is typical of a large number of such machines which are used simultaneously, one coning machine serving each yarn of the total warp delivered by the spin ning machine. For convenience of illustration, the threading-in operation will be described with respect to but a single unit, the arrangement of the units being shown in the block diagram which constitutes Figure 5 The machine of Figure 2 includes the usual elements of a cone Winder such as a pivoted traverse frame 10 and 2,75 1,16 l Patented June 19, 1956.
a spindle 11 adapted to receive thereover a cardboard cone on which the conical yarn body is wound. Yarn to be fed through a tube 17 having a Valve 18 therein. The
a manifold 19 which provides compressed air not only for the tube 17 but for similar tubesalong the entire row in Figure 5.
It is -now apparent that if air under pressure flows in the manifold 19 and valve 18 is opened, suction device of machines such as the row depicted yarn so disposed is cut,
will be immediately entrained in the jet of air and exhausted from the tube 15.
Referring now to Figure 6,
it is seen that the guide 20 is composed of a pair of inverted V-shaped members so The frame of the coning machine is provided with a notched tail making guide at 21 and a roller at 22, -the tailng device including a cutter device 23 which is arpassage of yarn therethrough when the of the cutter device 23 are given 1n co-pending application Serial No. 375,401, filed August 20, 1953, reference to which is hereby made.
With the foregoing background information, it is now possible to describe how the machines are dolfed according to the present invention.
During the winding-on operation, the yarn runs over the roller 12 and the dancer 13 to the button 14. When `in broken lines in Figure 2. The operator now presses down on the running thread between the button 14 and the cone, and in this manner passes the thread through the two inverted V-shaped members of guide 2t). At this stage, the yarn is still running onto the cone, but it is rst passing through the thread guide 20. The operator now cuts the yarn between the guide 29 and the cone whereupon the suction device obtains control of the yarn and jets the running end into tube 16 to waste. in order to eliminate friction losses, the running yarn is slipped out from under the one side of guide 20 through which it is still running so that it passes from button i4 directly into suction device 15. At this stage, the full cone can be removed from the spindle 11 which is stopped by conventional means with which winding machines are always equipped. The operator then presses upwardly on the .running yarn between the suction device and the button 14 so as to divert the yarn into guide 21 and over roller 22 whereby it automatically registers in the cutter device 23. The yarn now runs in the full line path of Figure 2. The operator next simultaneously places an empty conc on the spindle and starts the spindle. The empty cone catches the yarn at the base of the cone and causes it to be cut at 23. The running end then starts to form the tail on the base of the cone, passing over guides 24 and 21. The end between the cutter 23 and the suction device is quickly sucked in and discharged through the tube 16. When the tail is formed, the operator presses handle 21a, retracting guide 21 and releasing the yarn. He then starts the traverse and restores the traverse frame to the full line position of Figure 2. At this stage the doiling is complete and winding on may proceed until the new `cone is fully formed. At any stage after the last of the waste is taken in, valve 18 can be closed. The operator then moves to the next station and repeats the operation on that machine.
Up to this point, nothing has been said of the waste that issues from the tube 16. If reference is made to Figure 1, it will be noted that the waste discharging from tube 16 enters a funnel like member 2S leading to a Waste receptacle 26 on a wheeled dolly 27. As seen in Figure 4, receptacle 26 is provided with a hinged lid so Waste may be removed therefrom. Above the waste receptacle, the dolly 27 is provided with vertical standards 28 and 29 having cone supports 30, 31, etc., extending from either side. Standards 23 and 29 are supported by frame 32 which is cross connected at the top as can be seen in Figure 3.
Because of the fact that the dolly 27 is ambulant and because of the straight line arrangement of successive coning machines, an operator may accomplish successive doffing of a large number of winding machines in a most economical and efficient manner. To see how this is done, reference is made to Figure 5. In that figure, coning machines 33 to 38, inclusive, arediagrammatically shown, each machine corresponding in structure and in function to the machine shown in Figures l and 2. The manifold 19 runs for the full length of the group, and each machine has a tube 16 in exactly the same relative position. This being the case, the dolly is merely pushed from stage to stage with automatic registry of the funnel member 25 at each station. It will be noted that funnel member 2S is connected to dolly 27 at such an angle that when the member 25 is aligned under a tube 16 the dolly 27 is positioned a suicient distance away from the machine being doffed so as to not interfere with the operators movements. Thus, without interruption, the operator may serve twenty-four machines before its waste receptacle and cone supports are full. This makes for scheduled doing which reduces waste and at the same time keeps knot production at the desired low level.
What is claimed is:
1. The method of dofiing a winding machine including a rotatable spindle and a traverse for laying up a wound yarn body thereon from a continuous supply that comprises maintaining a suction zone, changing the path ot yarn travel between said body and said traverse so the yarn passes from said traverse to said suction zone and then to said body, cutting said yarn between said zone and said body whereby the succeeding portions of the yarn supplied are drawn into said suction zone and the spindle may be stopped for removal therefrom of the wound body thereon.
2. The method of threading-in a winding machine including a rotatable spindle and a traverse for laying up a wound yarn body thereon from a continuous supply that comprises maintaining a suction zone, changing the path of yarn travel between said body and said traverse so the yarn passes from said traverse to said suction zone and then to said body, cutting the yarn between said zone and said body while taking up at said suction zone the yarn continuously supplied, stopping said spindle, removing the wound body therefrom, changing the path of yarn travel between said traverse and said zone so the yarn passes from said traverse to said spindle and then to said zone, and thereafter cutting the yarn between said spindle and said suction zone.
3. In a winding machine including a spindle and a traverse the improvement that comprises a pneumatic yarn collecting device having a yarn receiving suction area and a guide tor guiding a loop of thread from said traverse through said suction area to said spindle.
4. A winding machine comprising a spindle; a traverse; a pneumatic yarn drawing device having a gas supply tube, a yarn eduction notch and a discharge tube; and a yarn guide on said device detining a yarn path from said traverse through said notch to said spindle.
