Shortly before the In the ex mp the Separator comprises a separator 5, I has reached the said intermediate spindle I (Fig. 13) which is provided with a position, an axial movement of the spindle l selector wing 2 and two lateral lugs or disis initiated in the direction of the arrow shown patchers 3 and 4 on its end face. The spindle I in Fig. 4, the thread a1 passing closely by the tips traverses a guide sleeve 5 which is mounted ro of the two retaining elements I and 8 (Fig.3). tatably on a carriage or slide (not shown). The Upon further axial movement of spindle l, the latter is guided in known manner on rails which said thread is moved away from the non-seprun transversely above the warp. The said slide arated threads by means of the wing 2, as shown in Fig. 4, in which the spindle I has covered part of its axial travel. When, subsequently, the separator 5, I has arrived in its second terminal position (Fig. 5), the separated thread 411 (Fig. 6) has been removed a considerable distance from the non-separated threads. When the separator 5, l rocks from the position of Fig. 3 into that of Fig. 5, the retaining element 1 has arrived in the path between the separated threads (11 and the non-separated threads. The separator 5, I then first remains in its angular position shown in Fig. 5,, but the spindle .I is drawn axially into the guide sleeve 51 so as to arrive in the position shown in Fig. 8, the wing 2 releasing the thread b1, whereupon thewin'g sleeve for the further operating element, said 2 exerts a pressure onto the non-divided threads G2, 122, as and so on. The separator 5, I then is rocked back into its initial position, the expelling movement of wing 2 having alreadly been initiated in the intermediate position shown in Figs. 9 and-10, and the thread in thereby 'having been removed from the non-separated threads. Shortly afterward the dispatching lug 4 engages the first separated thread :11, owing to the axial movement of spindle I and to the rotary movement of the latter along with the guide, sleeve '5, and moves the said thread through an additional distance in the'direction of separation, as may be seen in Figs. 11 and 12. In Fig. '11, the separator has returned into the initial or startingposition of its rocking movement. As-soon as the spindle I has returned from the axial position of Fig. 12 to that of Fig. 2, the separator 5, I has resumed its initial position as shown in Figs. 1 and 2, whereupon the cycle is repeated by separating the thread as and so on. What I claim as new and desire to secure by Letters Patent is:

1. In apparatus, threads of the type having two lease rods for grouping thewarp thread rockably about an axis parallel to the lease rods and outside the lease, the improvement comprising the provision of a rockable shaft located outside the crossing of the threads and extending parallel to the lease rods, said rockable shaft having a first operating-element and also a further operating element, said further operating element being confor separating leased warp nected with the first operating element to turn 50 further element having a spindle which passes through said sleeve axially, and means connecting said spindle withsaid sleeve for rotational driving, said sleeve having two retaining devices standing opposite each other for the thread group.

3. In an apparatus for separating leased warp threads, the improvement set out in claim 2, in

1 which the two retaining devices are formed as plane surfaces.

threads, the improvements set out in claim 3, in which the spindle has two forward lateral arms for displacing the separated warp thread.

5. In an apparatus for separating leased warp threads, the improvements set out in claim 1, in which the separator element is a spindle having means for separating the threads and moving the separated threads away from the warp, said spindle having two lateral lugs acting as dispatchers for the previously separated thread when displacing a freshly separated thread.

6. In an apparatus for separating leased warp threads, the improvement set out in claim 1, in which the separator element is a spindle having means for separating the threads and moving the separated threads away from the warp, a guide sleeve for transmitting rocking move ment to the spindle, said spindle traversing the guide sleeve.
