It is now the work. way of the invention Warp thread joining machine described?

If the housing 1 is moved somewhat by rotating the handle H at the end of the hand lever shaft 32 according to FIGS. 1 and 19, the cross bars 36 and 37 of FIGS old warp thread S. or K on the side that is not attached to the stops 38 and 38 as well as 39 and 39 for the corresponding thread lines of the new and old warp. threads S and K are pressed, which are located crosswise to each other between the displaceable clamp 35 and the thread holding rod 62 and 62, due to their elasticity and the actuation by the thread entrainment brushes 60 and 60 are drawn vertically into the ready position on the circular path of the thread-pulling hook 4θ, and then the sensors 10 and 10, which are from the bolts 11 and 11 of the

309 8 8 3/0894

Push rods 5 and 5 are supported in front of the housing and the holding rods 33 and 33 of the housing 1, are also moved somewhat. Further, to be pulled to the side of the housing 1 of the new and the old warp thread S ₁ and K ₁ on the circular path of the thread pulling hook kO, which is located at the lower end in the readiness position by means of the thread driving hook 3 ^ according to Fig. 1 and 2, so 8, the sensors 10 and 10 move the push rods 5 and 5, which are coupled to the holding rods 33 and 33 via the bolts 11 and 11 in the direction of arrow P, and the corresponding recess 7 and 7 at the lower end of one end of the associated The push rod is pulled towards the inside of the associated guide groove K and k of the guide plate 3, after which the movement is stopped by applying the associated feed control pin 9 and 9 to the guide plate 3.

Simultaneously with this, the control plates 12 and 12, which are provided opposite on one side of the push rods 5 and 5, press the claw levers 2k and Zk ₁ by engaging with this part of the lever, and hold the corresponding hook claw 26 of the associated ratchet lever and the The pawl 21a and 21a of the pawl disks 21 and 21 on the camshaft 18 out of engagement and, while the movement briefly stops in such a state, the part of the new and old warp thread S and K ₁ is pulled through the thread-pulling hook kO , and At the same time, the new and old warp thread S ₁ and K ₁ are pulled through the thread entrainment hook 3 ^ one after the other between the fixed blade 45 and the movable blade 59, after which the portion of the threads is cut off by actuating the cam 47 according to FIGS.

309883/0894

231662

Then, simultaneously with the cutting of the threads, the cam 23 moves on the camshaft 18 in the direction of the arrow 7 and 8 and comes into contact with the correspondingly curved control cams when the control cams 14 and 14 of the push rod operating levers 13 and 1-3 through whose actuating part 23a apply, which is why the corresponding Push rod operating levers 13 and 13 necessarily in a direction opposite to the direction of the arrow P can be moved around shaft 15 and 15, and the part of the underside of push rods 5 and 5 »which then goes over" the curved plates 16 and 16 is in contact with the top of the operating lever is pushed upwards » Then the engaging claws 17 and 17 are hooked and pushed back to one end of the recesses 6,

6 of the push rods 5 »and the corresponding recesses

7 and 7 are moved so that they do not get caught in the guide grooves h and k , and then by stopping the return control pins 8 and 8 on the push rods 5 and 5 against the inside of the guide plate 3, the condition for preparation of the next operating sequence is restored .

The described operation is repeated under normal conditions, so that the new and the old warp thread S ₁ or K ₁ are drawn one after the other onto the same line or axis.

If either the new or old warp thread S ₁ or K _{1 is} thin or the threads are twisted as a result of an extremely dense arrangement, or if instead of the new and old warp thread S ₁ or K ₁ in contact with the sensors 10 and 10 only a "thread touches one feeler, since that

3098 83/089

231662

ajidere thread is broken, the sensor 10 and the push rod 10 on the side which detects a thread, as described above, actuated, ie the relative position of the push rods 5 and 5 is changed, as shown in FIGS. 9 and 10 is shown , whereby the pawl lever 2k on the side of the other push rod 5b is not exposed to the control plate 12 of the push rod 5b, and at the same time with the stopping of the operation of the guard A by applying the hook pawl 26 of the pawl lever 2h to the pawl 21a of the pawl disc 21 on the Camshaft 18 the operation of the handle H of the housing 1 also gradually stopped. So if a defective thread occurs and the hand lever shaft 28 of Figs. 1 and 3 is operated by the handle 28a, the pawl cams 29 and 29 attached to the hand lever 28 are rotated in the same direction as the lever shaft, so that the other pawl lever 24, the the circular path protrudes therefrom, is pressed in the same direction, which is why the hook pawl 26 of the pawl lever 2h is disengaged from the pawl 21a of the other pawl cam 21 on the camshaft 18 by shifting the pawl lever 2h. In this way, when a malfunction occurs in the new or old warp thread S ₁ or K ₁ , the whole operation of the housing 1 is immediately stopped at such a point, and by eliminating the malfunction, the new and old warp threads become normal S or K ₁ restored, in which both warp threads lie side by side on the same line that touches the sensors 10 and 10, whereby after resumption of operation, the new and the old warp thread S ₁ and K ₁ on the side of the sliding The clamp must be cut off by the thread cutter B and the part of the thread is pulled to the thread pulling hook hO and then the connecting device

3 ü 'J ii ά 3 / Q 8 3 U

231662

device C is reached on one side on the circular path of this hook and continues through this device almost continuously to the position 40a, which is shown in dashed lines in FIG. The part of the new or old warp thread S or K is held on the projection 54 and carried along by the guide member 55, which rotates, and at the same time unnecessary thread ends of the new and old warp thread S and K by the. Shear device 58 cut off or sheared off. Simultaneously with this shearing, when the new and old warp threads S ₁ and K ₁ , respectively, which are guided by the guide member 55, undergo one revolution, as can be seen in FIG the part of the old warp threads S ₁ and K _{1 is} pulled into the hook 49 of the retraction hook 50 coming from the inside of the hook guide cylinder 51, and at the same time the two warp threads S ₁ and K ₁ are retracted due to a reverse rotation of the retraction hook 40 united. The end 63 united in this way is held one after the other on the thread holding rod 62 which extends from the hook guide cylinder 51 according to FIG. 1.

On the other hand, immediately before the thread end F of both warp threads S and K, which is cut by the shearing device 58, falls cut into the thread receiving container 59 according to FIG. 1 and FIGS. 15 to 18, it is held between the upper and lower gripping claws 72 and 72 that are staggered. Simultaneously with the severing of the corresponding thread ends from the thread-pulling hook 40, these ends are cut off by the shearing device 58 in FIG. 1.

3UÜ8b3 / 0 8

Synchronous Rait the previous operation results in the cam 69 on the main shaft 30 according to Fig. 1 and 16, a rotation, and by their control cam which is printed an end of the lever 66 by the left lever 78, said left lever actuated by the pin 79 as shown by dashed line 78a. The operating rod 81 connected to one end of the bell crank and the connecting rod 80 are operated around the pin 79 as shown by the broken line 81a, and one end of the lever 71 of the lower shear plate 70 is operated around the pin 69 pushed up. The lower shear plate 70 is moved in the direction of the arrow as shown in dotted line 70a, and at the same time, the upper shear plate 73, which is inclined to the lower shear plate 70, is inclined downward due to its own weight as shown by 73a, after which the control lever 77 of the shaft 75 strikes the part of the fixed plate 64 as shown in Figs. 15 and 16, and is then stopped.

Previous the corresponding end of the thread F has been sheared below the lower gripping jaws 72 of the lower shear plate 70 as shown in Fig. 17 is shown, which is why the inclination of the lower shear plate 70, the thread end at shearing in the horizontal direction from the .gehörigen to-top gripping claws 76 has been pushed down into the thread end receptacle 59. Simultaneously with the exit of the thread end F from the corresponding upper gripping claws 76, the relationship between the cam disk 65 and the lever 66 is returned to the initial state, and the angle lever 78 and the actuating rod 81 are also returned to their initial position,

309883/0894

231662

and at the same time the lower shear plate 70 is through the Total force of tension spring 83 at the end of lever 71 reset, and finally, with this movement, the upper shear plate 73 is pushed up for the next actuation.

Progress of the invention;

Since the present invention automatically creates a new Connects warp thread with an old warp thread when weaving through the warp thread joining machine according to the invention, is a fundamental difference to the conventional machines achieved where an extraordinarily time-consuming and tedious work has to be expended one after the other to join a new warp thread with an old warp thread, which is why the performance of the conventional looms is relatively low, because they because of the warp thread joining have to stand still for a few hours. By the invention Warp thread joining machine, on the other hand, is that Joining the warp thread achieved in an extremely short time.

The invention also provides a pair of an upper and a lower cross bar, which are provided with the stops 38 and 39 under the displaceable clamps 35 and 35, these being alternately pivoted by half a turn of 180 ° and then alternately the lines of thread or - Push back lines of the associated new and old warp threads S and K, so that the first and next threads of the corresponding thread lines can be safely pulled into the ready position on the circular path of the thread-pulling hook hO over the thread-taking brushes 60 and 60.

30988 3/0894

The invention also reliably determines whether the new and the old warp thread S ₁ or K. have been pulled onto the circular path of the thread-pulling hook 40 by the sensors 10 and 10, which are present in the feed direction of the housing 1, and if one of these If the warp thread has not been pulled, the operation is immediately stopped by the housing 1, after which the warp thread joining can be safely performed.

The present invention is also designed so that the new and the old warp thread S ₁ and »K, which are drawn on the circular path of the thread-pulling hook 40 in the ready position, are drawn separately to the thread grooves 41 and 42 of the thread-pulling hook 40 and regardless of the thread size the threads are safely taken along and fed to the connecting device C.

Furthermore, according to the invention, that part of the new and old warp thread S ₁ or K ₁ , which is taken along by the thread-pulling hook 40 in the ready position, is hooked by the thread-taking hook 34, and the part of the new and old warp thread S ₁ or S is caught by the thread cutter B K on the side pinched by the slidable clamp is inevitably cut off by the fixed blade 45 and the movable blade 48. This differs from the previous procedure in which, as a result of a "negative" cutting by pressing the threads against a stationary blade, disturbances occurred after the thread joining, namely due to a lack of synchronization of the cutting, caused by a thread stretching of elastic threads, while according to the invention the thread joining is undisturbed and reliable due to the inevitable cutting

of the old and the new warp thread S ₁ or K is made. ·

Furthermore, according to the invention, the retraction hook 50 with the hook 49 is slidably inserted into the hook guide cylinder 5, and the end of the two warp threads S 'and K. is hooked by moving the hook 49 by moving the hook 49 to and fro to the outer edge, which is why simultaneously with the ¥ ickeln the two warp threads S and K ₁ , which are pulled through the guide member 55 from the thread-pulling hook 40, around the circumference of the hook guide cylinder 51, both warp threads S ₁ and K ₁ can be securely connected, the part of the two warp threads S ₁ and K with the hook guide cylinder 51 is hooked.

Finally, it is achieved by the invention that the thread end F of the new and the old warp thread S ₁ or K, which is pulled to the connecting device C by the thread-pulling hook 40, is cut off after it is between the corresponding upper and lower gripping claws 72 and " J6 of the upper or lower shear plate 73 or 70 has been sheared off, which is why the thread, regardless of whether it can shrink or is thick, can be properly received by the thread end receptacle 59 and finally the thread end F is properly picked up side by side in line without jumping away becomes, which is also beneficial.
