As stated above, the carriage 64; the storage device operated by the reverse, rmotoe 418o. This reversible motor is. electric with a pole inverter 496 mounted on the fixed frame of the storage device tied together. The handle 497 of this reverser can be moved into positions around one; Run forward, run backward and switch off. of the reversing motor to effect.

For an automatic movement of the handle 49'7: this. Polwenders. 496 to cause in the off position when the movable gripping members 76 one of their extreme positions, as in Fig. i and. 3 is shown, reach-, and. around a movement of the handle, the reverser in the same switch-on position as To prevent it from switching off automatically, the following control and locking elements provided: a vertical., slidable in bearings i2o, and 122 of the fixed frame of the storage device carries control rod a horizontal control finger passing through a slot 126 in said frame 124. A cylindrical helical spring 128 interposed between bearing 122 and a on the control bar i i8 attached adjusting ring r3o is arranged, prevents d.aß the control rod falls. The adjusting ring i3, o carries a stop i3; a., And in; similarly carries one attached to the upper end of the control rod i i8 Adjusting ring 134 a stop 136. One on the slide. 64 ordered control organ works with these two stops 132 and 136, which are at a distance are attached from each other., which is essentially equal to the "stroke of the carriage is .. The horizontal control finger 124; reaches into the space between the. Arms: i4o and ias2 of a fork-like part of the handle 497 of the pole turner. 496 to work with one of these poor people.

The operation of the control and locking elements described above is as follows: During the normal warping process, ie as long as no thread breakage occurs, the carriage 64 .. with its movable gripping elements 76 is in its upper, inoperative position and the pole turner 496; 497 in the in Fig. I in; position shown in full lines. After the occurrence of: a thread breakage and the automatic stopping of the drive motor 46 of the warping machine 2o and the automatic entry into force of a braking device acting on the tree 44, the reversing motor 48o of the storage device for the purpose of moving the carriage 64 into its lower effective position by turning the handle 497 of the reverser 496 is started in a clockwise direction in the position 49711 shown in dash-dotted lines in FIG. The arm 140 of the fork-like part of the handle 497 is moved away from the control finger 124 in this way and the arm 142 is brought into the dot-dash position 142a on the control finger 124 Approaching the effective position, the control element i, 3; 8 strikes the stop ip, whereby the control rod m8 is moved downwards against the action of the spring 128. During this downward movement of the control rod 118, the control finger 124 comes with the arm i42 (the handle of the Pole inverter engages so that the latter is automatically rotated into the switch-off position shown in FIG , and the control finger 24 in contact with the arm 142, so that under these circumstances it is impossible to turn the handle of the pole changer clockwise again, with and In other words, the handle of the pole changer cannot be rotated to the same switch-on position as it was before its automatic movement into the switch-off position. After tying the ends of the broken thread together, however, the worker can use handle 497 of the reverser. Rotate counterclockwise to position 497 shown in broken lines in FIG. 3 in order to cause the carriage 64 to be lifted by the reversing motor. In this way, the arm 142 of the fork-like part, the handle 4.97, is moved away from the control finger i24 and the arm @ 4p is brought to the control finger s12 !: in the position i4pb shown in dotted lines. After the start of the lifting of the slide 64, the control member: 138 is out of engagement with the stop 132, so that the spring 128 can relax to a certain extent and cause the control rod I18 'to be lifted slightly until: the control finger 124, reached position 124b on the upper arm shown in dash-dotted lines in position i4ob. When the carriage 64 approaches its inoperative position shown in dash-dotted lines in FIG. 3 and in solid lines in FIG. the stop 136, whereby the control rod i r8 is raised so that the control finger 1,24 touching the arm i4o of the handle 4.97 causes an automatic movement of the handle 497 into the switch-off position shown in FIG. In this way, the reversing motor 48o and d become slides. 64. stopped automatically. Since the stop 136 is in contact with the control member 138 and the control finger 124 with the arm 140 when the slide is in its highest position, the handle of the pole changer cannot be rotated counterclockwise again, so that a Careless switching on of the reversing motor in the same direction of rotation as before its automatic stop: is made impossible.

The stationary frame of the storage device 2! 2 carries three switches for connection to the electrical circuits. the warping machine 20, and the slow speed switch 49o, the auxiliary starter switch 492 and the control switch 494. All of these -, - three switches are in the open position when the carriage 64 with its gripping organs. 76 in its normal ineffective Position and the reversers 4.96, 497 are in their switch-off position, as in. Fig. I is shown. The arrangement of said switches 490, 4.92,, 494 in the electrical circuits of the warping machine is shown in FIG. the Circuit is chosen so that the auxiliary starter switch 4.92 and the control switch 494 are connected in series that a closing. of the auxiliary starter switch a working d.; s electric motor. 46 causes the warping machine 2o, which drives the tree 44 when the control switch 494 is closed, and that the electric motor 46 of the Schärmaschirn ° 2o, as long as the slow speed switch 49o is closed, only at very low Speed, d. h, can be set in motion with a so-called slow run. The slow speed switch q: 90 is controlled by an element 491 which is attached to the movable carriage 64 is. Nominal. the carriage: is in its upper inoperative position, touches the control member 491 the spring-loaded push button 14; 4 ': of the switch 49o, see above that the latter is kept in the open position. Once, the controller 491 during the downward movement of the carriage 64 out of engagement with the spring-loaded Push button 14L (. Is reached, the slow speed switch 4; 9o is closed Slow speed switch remains in its closed position until the controller 491 during a subsequent. Upward movement of the slide the control member 49i touches the push button 144 of the slow speed switch again. The slow speed switch 490 is therefore only open to normal operation of the electric motor 46 of the warping machine 20 to allow high speed when the carriage 64, with its movable Gripping members 76 in, its inoperative position. It's closed to one: operation of the electric motor 46 of the warping machine 2o only with slow running when the carriage 64 is removed from its inoperative position.

The auxiliary starter switch 492 is controlled by an organ 493 which is firmly connected to the arm nq! o, the handle 497 of the pole changer 496 or with this arm is made in one piece. The control element 493 is designed in this way and arranged that it is out of contact with the spring-loaded push button 1q; 6 des Auxiliary starter switch 492 is when the handle 497 of the pole changer 4.96 is, for example in the in Figure 3; is in the switch-off position shown in solid lines, and that it is the spring-loaded push button 146 of the auxiliary switch 492 for the purpose Closure of the same touches, so a working of the electric motor 46 of the warping machine 20 to effect when the handle 497 of the pole changer 496 in a clockwise direction opposite direction in that shown in Fig. 3 in dash-dotted lines Position is rotated to an upward movement of this carriage 64 from its lower effective in its upper ineffective - to effect position. When the handle 497 of the pole changer 496 clockwise. in the in Fig. i in dash-dotted lines position shown is rotated to a downward movement of the carriage 64; the end to effect its upper inoperative position can: the control element 49.3; the Do not touch the push button 146 of the auxiliary starter switch 492, so that the latter remains in the open position. It may also be mentioned that the control element 493; of the auxiliary starting switch 4.92 is of such a length that it is the auxiliary starting switch shortly before closing the pole changer 496 by turning the handle 497 in an opposite clockwise direction for an upward movement of the slide 64 closes.

The control switch 494 is controlled by a control element 49.5, the clipboard resting loosely on the extensions 1o6, 1o8 of the carriage 64 i io attached is .. once: the clipboard mo while lowering the slide 64, is placed on the fixed terminal board 1o2, as shown in Fig. 2, the control unit -195 touches the spring-loaded one. Push button 148- of the control switch 4! 94 to close it. The control switch 494 remains in the closed position, until the clipboard i io during a subsequent life of the carriage 64 of. the fixed terminal board 1o2 is lifted, as shown in FIG. As above As mentioned, the control switch 494 is in series with the auxiliary start switch 492 switched. Therefore, closing of the auxiliary starter switch 492 by the controller 493 only cause the electric motor 46 of the warping machine 20 to work, albeit the control switch 494. is closed. The working of the through the auxiliary starter switch 4.g2 started electric motor 46 of warping machine 20 is interrupted as soon as-the Control switch 4941 while lifting the slide, 641 by moving the the control organ 4,951 bearing. Clipboard i io of. the solid. Clipboard i.oz is opened.

In view of the foregoing description, the following procedure, the Storage device can be understood: A turning of the handle 497 of the pole turner 496 clockwise. to lower the carriage 64 does not work. of Electric motor 46 of the warping machine. Turning the handle 497 is set in the opposite direction clockwise for the purpose of lifting the carriage 64 after placing the clipboard mo on the fixed terminal board 1o2 causes the electric motor 46 of the warping machine to work 20, at a very low speed; since the slow speed switch is 4.90 in this one Moment is closed; , the operation of the electric motor 46 is interrupted, as soon as that the. Steuerorgan4,95 of the control switch 4, .94; carrying clipboard iio from the fixed: terminal board 102 is lifted, although the auxiliary starter switch 4; 92 still closed. is. As soon as the carriage 64 is in its uppermost inoperative position is reached, the handle 4.97 of the pole changer .496 is automatically in the switch-off position turned, whereby the control member 4K) coupled with this 3 the Auxiliary starter switch opens. At the same time, the slow speed switch is switched through his control member 4; 9I mounted on the carriage 641 is opened so that the Electric motor 4.6 of the warping machine 2o at normal high speed by pressing normal start button 318i2 on the frame. attached to the warping machine and conductively connected to the electric motor 4; 6.

The main switch i'll be opened, and the supply of the electric motor 46 with direct current is interrupted at the pole 311 as soon as the above. described holding circuit of the release magnet 374 is interrupted either at the push button switch 4:14 or at the switch 4o6 of the chain brake relay 4o8 or at the switch i1, a2 of the counter relay 4o4. The opening of the push button switch 414 occurs when. the warping machine is stopped by hand, the opening: the switch 4o6 takes place when one or more thread monitors 416 fall in the gate and close a control circuit as a result of a thread break. The opening of the switch 40a takes place: when the normally closed switch 418 of the interrupt counter 98 located on the warping machine is opened after a certain number of revolutions of the tree.

Any of the above: Interruptions in the holding circuit of the Trip solenoid 3-7q, causes brake solenoid 318 to be energized for an immediate strong application of the brakes of the warping machine and: a decrease in excitation this brake solenoid 318 to a certain value after a short period of time, for example 2 seconds for a subsequent slight application of the brakes Warping machine until the electric motor _1i6 of the warping machine comes to a standstill. The circuits containing the solenoid 4,34 of the solenoid brake relay q; 312 and the solenoid 410 of the timing relay 4ita: for controlling the excitation and reducing the excitation of the brake solenoid 3, 18 through the variable throttle coil 43,3, as shown in Fig. 8, are described in more detail hereinafter.

The normal high operating speed of the electric motor 46 of the warping machine can be set by a hand rheostat 35o arranged on the warping machine. This manual rheostat or generator field rheostat 3.5p, which regulates the voltage of the direct current supplied to the electric motor 46, is arranged in: the following circuit: A line 444 leads from the end 445 of the coil 4q6 of the generator field rheostat 3; 5p to the pole M3 of the main switch M. , which in turn with the connection point 44, e! connected in line 3, 8'8 by a line 4.5o. is. A line 4,52 leads from this connection point 448 to the terminal 4i54 of the exciter 456 of the motor converter 26. The terminal q: 5.8 of the exciter 456 is connected to one end of the field 46o of the direct current generator 3,56 by a line 462. The other end of the field 46o is connected to the movable finger 464 of the hand rheostat 35'a by a line 4; 66 which contains the switch 468 8 of the relay 41o8. The end 44t7 of the coil 44.8 of the hand rheostat 3: 5, o is connected to the connection point q; 70 in the line 462 by a line 4.72 which leads to the connection 474 through the part of the line 398 connecting the connection point 474 to a connection point 476 and: by a line connecting the connection point 476 to the connection point 4.7o. .1,7.8 leads. As can be seen from the circuit connections described, the generator field 46o is excited by the exciter 4; 56, which generates a constant potential. This potential is applied to a circuit which consists of the left part (as can be seen in Fig. 8!) Of the generator field rheostat 215.9 in parallel with the generator field 46o and the right part of the generator field rheostaten.3.5o in series with these consists. Movement of the finger 464 over the hand held rheostat 315o causes a change in the value imposed on the generator field .16o. Potential and consequently a change in the current flowing through this generator field during normal operation of the warping machine. For example, if the finger 464 is moved to the right, the excitation of the generator field and the current flowing through that generator field are increased. Therefore, the current flowing through the generator field corresponds to the setting of the finger 464; of the hand rheostat 350- This current when it is high gives a high voltage produced by the generator 3; 56 when it is low, a low one. The normal high operating speed of the electric motor 46 at the beginning of the warping process is determined by the voltage of the direct current supplied to the electric motor, and: therefore the normal high operating speed of the electric motor can easily be set by the hand rheostat.

As stated above, in certain circumstances it is very low Speed or so-called slow running of the electric motor 46 is desired. First, for example after the occurrence of a thread break at a point between the gate and: the Tree and tying the torn ends together. : of the thread after unwinding part of the chain from the tree by means of the storage device, or secondly at the beginning of a warping process, until a few layers of the winding are wound onto the tree have been. In the first case, the one should be merged in the storage device Chain through the tree in the warping machine at very low speed during the Retraction of the gripping members 64, 76 of the storage device by the reversing motor 48o taken from its lower operative position to its upper inoperative position are released until the chain is released by the clamping members 1o2, iio of the storage device is, and in the second case the chain should be attached through the tree in the warping machine very low speed until the actual warping process takes place to the Winding up a few layers at the normal high, speed safely can begin.

In both cases mentioned above, the switch 4A & controlled by an electromagnet 4ß2 of the relay 4 (o8 'is opened in a manner to be described below, so that the hand rheostat 350 is disconnected from the generator field 46o arranged between the connection points 48.6 and 488, so that after the above-mentioned disconnection of the hand rheostat 3) 5.0 from the generator field 46o, the current now flows through the following: Circuit: exciter 45.6y line 462,, Gen-erato: i-field 46o, line 466, rheostat q; 84, line 4l44;, pole M31 lines 45o, 4512. Under these circumstances. Therefore, a current proportional to the combined resistance of the generator field 46o and the control resistor 04, which are connected in series with one another, flows through the generator field, dier one. Causes power flow, which causes the low voltage required for the very low speed and the äeringe torque of the electric motor 46. It may be mentioned that this power flow and therefore the voltage and the torque are independent of the setting of the hand rheostat 3-5o, since the latter is switched off at the front of the generator field 46o. On the other hand, the hand rheostat 3, 5, 0 is again connected to the generator field 4; 6o and further operation of the electric motor 46 at low speed is made impossible as soon as it is activated by the electromagnet. 4ß21 of relay 40; 8. controlled switch 468 is returned to the closed position.

The solenoid 482 of the relay 408 is controlled by the slow-down switch 419o located on the carriage 64 of the storage device 22 @. For this purpose, the slow-speed switch 49o is arranged in the following circuit, starting from the left terminal of the slow-speed switch: line 528, leading to connection point 530, line 513,2, connecting connection point 530 with a connection point 534, line 536, the connection point 534 connecting to a connection point 538, the part of a line 540 between connection points 538 and 542, line 544, connecting connection point 542 to one end of a secondary winding 546 of a low voltage transformer 548, line 55o, from the other end of the secondary winding 546 to a connection point 552 Leading, line 554, connecting point 552 to the electromagnet 556 of a relay 558, line 56o, connecting the electromagnet 556 to one end of a variable resistor 562, and line 564, the other end of the resistor 562 to the right terminal of the slow speed switch 490 connecting.

The electromagnet 55i6, -des, relay 5) 56 controls a switch 5t66. This switch 5.66 is in the following circuit, starting from. the left terminal of the switch, arranged: line 56! 8, leading to the Etektromagnieten 4; 8; 2f of the relay 408, the part of the line 540, which the electromagnets 4t8,2. connects to connection point 542, line 544, secondary winding 546 of transformer 514.8, the part of line 51,50 which leads from secondary winding 546 to a connection point 570 in this line, and. Line 57/2, this one. Connection point 5.70 with the right; Terminal of switch 566 consumed.

The primary winding 5; 74 of the low voltage transformer 548 is connected to VAC feed lines 428 and 5t16 by lines 576 and 5:78, respectively.

In passing it may be mentioned that the switch 5ieo of a relay 5; 82 open; and the switch 581 of the relay is closed when the. Stoking system is switched on for operation.

As can be seen from the above description, closing the slow speed switch 490 when the slide 64 of the storage device is removed from its uppermost inoperative position causes the electromagnet 556 to be energized, which in turn causes the switch 566 to close again, which energizes the Electromagnet 482 results, which closes the switch 468 for the purpose of disconnecting the hand rheostat 350 from the generator field 46o, whereby an operation of the electric motor 46 of the warping machine is made possible only at slow speed. When the carriage returns to its uppermost inoperative position, the slow-speed switch 490 is opened, so that the electromagnets 556 and 482 are de-energized and the switch 468 is opened for the purpose of reconnecting the hand rheostat 350 to the generator field 46o, whereby the electric motor 46 of the warping machine operates at a high rate Operating speed is enabled.

Incidentally, it may be mentioned that the electromagnets 556 and 48.2 can also be controlled by the thread monitor 416 in the gate.

The auxiliary starter switch mechanically coupled with the pole changer 496 492 is in the following circuit, starting from the left terminal of the auxiliary starter switch, arranged: line 583, leading to the right terminal of the control switch 494, Line 584, the left terminal of the control switch 494 to the connection point 586 in line 384 connecting that portion of the line leading from the connection point 586 leads to the left terminal of the overcurrent switch 378, line 396, trip magnet 374, line 388, rheostat 258, line 396, box 394 of motor 46, line 398 up to the connection point 588 and line 59o, which this connection point 588 connects to the right terminal of the auxiliary starter switch 492.

In the first case, i. H. after a thread break and knotting of the broken ends of the threads after unwinding part of the chain from the Tree, the carriage 64 of the storage device 22 is in the lower one effective position shown in Fig. 3, so that the slow speed switch 490 and the control switch 494 are closed and the switch 4.6o of the Slow speed switch controlled relay 408 is open. When the handle 497 of the reverser 496 in counterclockwise to make the reversing motor 480 work to cause the carriage to move upward is the auxiliary starter switch 492 also closed by the control member 493, so that as a result of the closing of the slow speed switch 490 and the control switch 494 of the electric motor 46 of FIG The warping machine starts up at slow speed. As stated above, the auxiliary starter switch 492 closed shortly before the closing of the pole changer 496, so that the warp threads are already under a certain voltage caused by the electric motor 46, when the reversing motor 48o starts lifting the carriage 64. As soon as the sled after slowly taking up the chain collapsed in the storage device reaches the position shown in Fig. 5, the control switch 494 is opened, whereby the auxiliary starting circuit containing the auxiliary starting switch 492 of the motor 46 is interrupted so that the motor 46 is stopped. The upward movement the slide continues, however, and in the top inoperative position of the The auxiliary start switch 492 and the low speed switch become the low speed switch 490 opens automatically. Now switch 468 of relay 4o6 is opened, and the electric motor 46 of the warping machine can run at normal high operating speed Press the normal start pushbutton switch 382 to crank.

In the second case, i. H. at the beginning of a warping process, is initially the slide of the storage device into the intermediate position indicated in FIG. 2 64b brought. In this position, the slow speed switch 490 is closed and the switch 468 of the relay 408 controlled by this switch is open. now a slow running of the electric motor 46 of the warping machine by any length Depressing and holding the spring-loaded normal cranking pushbutton 382 obtained, d. H. until some layers of the winding have been wound onto the tree. Then the normal start button 382 is released so that the electric motor 46 is stopped as the circuit for normal starting at the starter pushbutton switch 382 and the switch 4o6 of the relay 408, which is controlled by the solenoid 482 is interrupted, which is still energized as a result of the closing of the switch 49o is. When the slide 64 falls into its uppermost inoperative position, the can Electric motor 46 of the warping machine at normal operating speed by depressing it of the crank button 382 can be left on for a short period of time since now the slow speed switch 49o is open, so that the solenoid 482 of the relay 408 is de-energized and switches 4o6 and 468 are closed.

As from the above description of the construction of the storage device and the arrangement of the circuits of the electrical device can be seen the storage device for temporarily unwinding the chain from the tree a warping machine can be used in the following way: During normal operation The carriage 64 of the storage device 22 is located in the warp machine its uppermost inoperative position shown in Fig. r, and the warp threads 3d. run from the reels 36 stored in the gate through a on the frame of the Storage device 22 arranged reed 38 through the space between the fixed gripping organs 56 and the movable gripping organs 76 on the carriage 64 are arranged, and by a reed 42, which is attached to the warping machine is to the one built into the warping machine and driven by an electric motor 46 Tree 44.

As soon as one or more threads 34 'break, the electric motor 46 the warping machine is automatically switched off from the power source, and a strong one Apply the brakes of the warping machine to stop the tree 44 immediately takes place, whereupon after a short period of time the brakes are applied to a certain level Dimension, as set out above, is reduced. This relaxation enables unwinding but prevents part of the chain from the tree through the storage device unwanted further rotation of the tree as soon as the storage device is used Completion of the unwinding process has been stopped.

Now the handle 497 of the pole changer 496 is turned clockwise, to cause the carriage 64 to move downward. As soon as the slide passes the Reached the position shown in solid lines in Fig. 2, the chain clamped by the clamping organs red, rro. This jamming of the chain takes place instead, just before the movable gripping members arranged on the carriage 64 touch the chain. During the further downward movement of the slide into the effective, The position shown in solid lines in FIG. 3 touch the gripping members 76 the chain 34 and go through the spaces between the fixed gripping members 56, removing part of the chain from the boom 44 against the slight braking effect the brakes of the warping machine is unwound. As soon as the carriage 64 is the Approaching the lowest effective position shown in Fig. 3, the pole changer 496, 497 automatically brought into the switch-off position for the purpose of stopping the slide.

Now part of the chain 34 is in a zigzag line in the storage device folded, as shown in Fig.3, and the ends of the broken thread or the threads can be easily tied together.

Then the handle 497 of the pole changer 496 is counterclockwise rotated to raise the carriage 64. Exactly at the same time, the brakes apply the warping machine is released, and the electric motor 46 of the warping machine is running at low speed started by the auxiliary starter switch 492 to the memory device merged Take up the chain at the same time as lifting the carriage until the carriage reaches the Reached the position shown in Fig. 5 and the chain 3.4 of the _Greiforganen 76 and the clamping members pulled, iio is released. Now the electric motor becomes 46 the warping machine is stopped and the carriage settles. its upward movement continues, until it has its topmost ineffective, in Fig. 3 in dash-dotted lines and in Fig. i in position shown in solid lines reached; in that of the Polwender 496, 497 and the auxiliary starter switch 492, 493 is automatically brought into the switch-off position will. The electric motor 46 of the warping machine can now operate at a normal high Start operating speed by depressing normal starter button 382 will.

The setup and operation of those shown in Figs. 9 and 10 Storage device is quite similar to that of Figures i through 7 and corresponding parts are denoted by the same reference numerals, with the essential difference being therein lies that the carriage 64 of the storage device shown in FIGS. 9 and 10 on one side, parallel to the chain 34, is open so that it has free access allowed to the chain when the carriage is in its shown in Fig.9 ineffective position. The body of the slide 64 consists of a casting, the one, cross member i.5o, a first longitudinal member 152, a second longitudinal member 154, a first extension 156, a second extension 158, and a set of im Having spaced supports 16o with overhanging parts r62. Each support 16o carries a transverse shaft 163 on which a roller 164 is rotatably mounted is. The overhanging portions 162 are opposite the spaces between the fixed gripping members 56 mounted on the frame 50, 52 of the storage device arranged. The roller set 164 forms the movable gripping members. The extensions 156 and 158 are slidably mounted on the vertical bars 78 and 8o, respectively are attached in lugs 82 of the frame of the storage device. A wave 92, on the gears 88 and 9o sit, the with the toothed part of the rods Comb 78 and 8o, is mounted in the extensions 156 and 158 of the carriage. A reversing motor 48o mounted on a bracket attached to the extension 158 166 is mounted, has the purpose of the shaft 92 by a gear reduction 96, the meshes with the gear 9o splined on the shaft 92, in rotation offset. The carriage 64 with its gripping members 164 can in this way be moved down or up by means of the reversing motor 48o in the same Manner like the reversible motor in the embodiment of that shown in Figs Storage device is controlled. The gear reduction includes a self-locking Slug.

The memory device shown in Fig.9 and io can in the same Used and operated in a manner similar to that shown in Figs.

In the embodiment of the memory device shown in FIG. 9 and ao are the supports 16o with the body of the carriage 64 only on one of its sides, parallel to chain 34, connected, i. H. the supports are with the longitudinal beam 154 connected. The overhanging parts 169 which carry the gripping members 164 allow the free access to the chain 34 on the side of the side member 152, i. H. at the Side of the carriage opposite the connection of the supports to the longitudinal beam 154, when the slide is in its inoperative position. If therefore from for whatever reason the number of threads in the warping machine for the next warping process be decreased, d. H. the width of the chain from width a to width b is to be reduced, the portion 34a of the chain from the storage device can be removed in the lateral direction on the side of the side member 152, in order to let the threads of this part rest in a suitable holding element 168.

While Fig. 9, the supports 16o of one piece with the body of the Representing carriage 64 consisting of, the supports can also consist of separate pieces be made attached to the side rail 154 in any suitable manner attach are.

The storage devices shown in the drawings are with equipped with a fixed and a movable gripping member. If so, however is, they can also be equipped with two movable gripping members that are relative can be moved towards each other.

The warping machine shown in FIGS described.

With reference to FIG. Ii, 2o denotes a warping machine, 22 a storage device, 24 a gate and 26 a motor converter for alternating current into direct current. The storage device 22 is connected to the warping machine 2o by screws 28. The gate 24 is located a suitable distance from the memory device. The motor converter 26 is supplied with alternating current from a power source (not shown) through the line 30 and sends the direct current to the various electrical equipment of the warping machine through a multi-conductor cable 32.

The warp threads run during normal operation of the warping machine 34 from the coils 36 stored in the gate through the space between one fixed gripping element 38 and a movable gripping element 4o of the storage device 22 and from there through a reed 42 to one built into the warping machine 2o and Tree44 driven by an electric motor46.

As described above, the storage device has the purpose of providing a Part of the chain 34 from the tree 44 in the event of a thread breakage by moving the movable gripping organ 4o from its ineffective, shown in solid lines Position in its effective position 40 'shown in dash-dotted lines to handle.

Although Fig. Ii illustrates a preferred arrangement of a warping machine, where the warping machine in conjunction with a storage device a certain construction is used, the warping machine according to the present Invention, if desired, can also be used without a storage device. The warping machine may incidentally be any suitable in connection with a memory device Type of work.

As shown in FIGS. 12 and 14, the drive motor 46 is on the frame 48 of the warping machine 2o arranged. The electric motor is direct with one keyed on the shaft 52 of the electric motor and by a nut 54 in its Position held drive member or drive head 5o coupled so that the drive head rotates at the same speed as the shaft of the electric motor.

A bracket 56 (see FIGS. Ii, 12, 14 and 15) is swingably attached to a fixed rod 58 which is carried by support bodies 6o and held in place by fitting screws 62. The support bodies 6o are slidably arranged on rods 64 which are supported by fixed parts of the frame of the warping machine. The support bodies 6o can be held in any selected position by fitting screws 66 (see FIG. 14). In order to balance the weight of the bracket 56 and the parts connected to it in the intermediate positions of the bracket between its effective upright position shown in FIG. 14 and its inoperative horizontal position shown in FIG. 15, two torsion springs 68 are wound around the rod 58, wherein one end of each torsion spring is attached to the rod and the other end of each torsion spring is attached to the bracket. The bracket can be held in its upright position by a locking screw 70 which is pivotally mounted on the fixed lug 72 which can cooperate with a supplementary locking member 74 on the bracket.

A bearing 76 attached to bracket 56 supports shaft 78 of a loose head 8o. The rotatable shaft 78 rests on rollers 82 of the bearing and is with Game arranged in the bearing, d. H. the shaft can also go in the direction of its longitudinal axis be moved. One side of a ball thrust bearing 84, which is on a sliding Rod 86 is arranged through a hole in a cover lath 88 of the bearing 76 passes through is in contact with the end of the loose head shaft 78. One between the plate 88 and the other side of the ball bearing 84 arranged spring go tends to press the latter against the end of the shaft 78. The loose one Head 8o and its shaft 78 can, to some extent, be in the direction of the Arrow A can be moved against the action of the spring go. The movement of the bar 86, the ball bearing 84, the shaft 78 and the loose head 8o in the opposite Direction under the action of the spring go is through one on the emptying End of the rod 86 attached collar 92 limited.

A gear 94 keyed on the loose head shaft 78 meshes with a gear 96 keyed on the shaft of an interrupt counter located above the bearing 76. The interrupt counter, which can be of any generally known type, serves to bring about an automatic stop of the warping machine as soon as the tree 44 has made a certain number of revolutions to which the interrupt counter has been set.

As shown in Figs. 13 and 14, a pair of adjustable support beams are positioned below the space occupied by a tree 44. Each support beam consists of two parts, red and io4, which can be adjusted to one another by means of a connection io6 made up of a slot and screw. The support beams ioo are connected with rods io8 and i io at their ends. The rod io8 is slidably and displaceably arranged in a bore of an arm 112 attached to the frame of the warping machine. A fitting screw 1 14 is used to hold the rod lob in the set position. The rod iio is slidably and displaceably arranged in a bore of a projection 116 of the adjustable support body 6o and is held in its position by a fitting screw 118. The support beams ioo can thus be adjusted in a certain position in relation to a tree 44 by the rods i o8, iio and fitting screws 114, 118, while the length of the support beams can be adjusted to the width of the tree used by the connection io6. Therefore, the machine can be used for trees of various sizes and shapes.

Fig. 14 shows a tree 44 of ordinary shape in dash-dotted lines Lines. The tree has flanges i2o and 122 at the ends of its hollow core 12q., And the central bore 126 is provided with a longitudinal groove 128.

The insertion of an empty tree 44 into the warping machine will now be described: For this purpose, the supporting bodies 6o, which carry the bracket 56 and the rods iiö of the support beams ioo, are brought into a certain position corresponding to the width of the tree to be inserted. If the supporting bodies 6o are of course already in the correct position, a special setting of the same becomes superfluous. The bracket 56 is swung into the horizontal position shown in Fig. 15, whereupon the empty tree can easily be inserted into the warping machine by sliding the flange i2o along the support beam until one end of the central bore 126 engages the drive head 5o . The conical shape of the drive head 5o facilitates the engagement and causes a slight lifting of the flange i2o from the support beam ioo. During the engagement of the drive head 50 with the central bore 126 of the tree, a wedge 130 arranged on the drive head is pushed into the longitudinal groove 128 in order to bring about a secure drive of the tree. The bracket 56 is then swung into its upright position shown in FIG. 14 so that the loose head 8o engages the other end of the central bore 126. The loose head is also conical in shape, so that the flange r22 of the tree is slightly lifted off the support beams to ensure that the tree can rotate freely. During the engagement of the loose head 8o with the central bore of the tree, the loose head can be displaced to a certain extent in the direction of arrow A (Fig. 14) against the action of the spring 9o if the position of the support body 6o is not exactly the Width of the tree used. In other words, the play of the loose head 8o and its shaft 78 described above allows slight differences in the width of trees of a certain normal size. After locking the bracket 56 in its upright position by the screw 70 , the operation of the warping machine can begin.

To get a full tree out of the warping machine after the completion of the Take out the warping process, the bracket 56 is in the horizontal; shown in Fig.15 Swung position, whereby the loose head 8o out of engagement with the central bore of the tree arrives, and the flange 12.2 falls on the support beams ioo. Has now the worker has free access to the flange 122 and can easily remove the tree from the Remove the warping machine by sliding its flange 12o along the support beam ioo.

11, 12 and 13, a pressure roller 132 of slightly smaller width than the distance between the flanges 12o and 122 of the tree 44 lies against the winding 134 on the tree. As shown in Fig. 16, the pressure roller z32, which is selected according to the normal size of the tree to be used in the warping machine, is interchangeably mounted in roller bearings 136 and 138, which are carried by arms 140 and 142, which are rotatable and slidable on a rod 144 are stored in bearings 146 and 148 of the frame of the warping machine. The longitudinal axis of the rod 144 is exactly parallel to the longitudinal axis of the tree 44. The arm 140 is attached to the rod 144 in any suitable manner, while the arm 142 is slidable and adjustable on the rod 144 so that the spacing between the arms 140 and the arm 142 can be adjusted according to the width of the selected pressure roller 132.

The arm 142 is held in place by a fitting screw 150. One end of the rod 144 protrudes from the frame of the warper and has a Groove 152 for engagement with an adjustment plate 154 attached to the frame by means of a cap screw 156 and a thumb screw 158 is attached. The adjustment plate 154, which rests against springs 16o and 162 around the shafts of said screws are wound, is used to hold the rod 144 in a certain position. the Position of the adjustment plate and the sliding rod 144, which the arms 14o, 142 and the pressure roller 132 carries can to some extent by the thumb screw 158 can be changed; so that the pressure roller in an exactly coincident with the tree Position can be brought. In other words, the setting described the rod 144 carrying the pressure roller 132 allows the adjustment members 15q4, 158 small differences in the width of trees of a certain normal size to.

The pressure roller 132 is pressed against the winding 134 on the tree a weight 164 supported by an arm 166 attached to the rod 144 is attached.

A combined speedometer and odometer 168 (Fig. 11 and 16), which is attached to the arm 142, is used to display the peripheral speed the pressure roller 132, and the winding 134 and the length of the wound on the tree q44 Chain.

As shown in FIGS. 11, 12, 13, 16 and 17, a crank 170 wedged onto the rod 144 is rotatably connected to one end of a drive element 172. The other end of the drive member carries a roller 174 which engages a cam 176 which is attached to a slidable carriage 178 by screws 18o (see also Figures 18 and 22). A fitting screw 182 (FIGS. 16 and 17), which is arranged on the drive element 172, cooperates with a stop 184 on the crank 17o and determines the angle between the element 172 and the crank 17o as long as the pressure roller 132- the winding 134 touched on the tree. A tension spring 186, which is stretched between the hooks of the crank 170 and the drive element 172, tends to bring the fitting screw 182 into engagement with the stop 184 and the roller 174 of the drive element 172 into operative engagement with the cam sliding surface 176.

As shown in Figures 13, 18 and 22, the carriage 178 has a groove 188 on each side for engagement with four guide rollers 19o mounted on a body 192 which is attached to the frame of the warper so that the carriage can be moved through the distance c = ca -I- b (see Fig. 13) by means of the control device 170, 172, 174, 176 when the swingable support frame 14o, 142, 144; which carries the pressure roller 132 is moved through the angle y = a +, B during the growth of the winding 134 on the tree 44.

According to FIGS. 18, 21 and 22, the carriage 178 has a recess 194 for receiving the main part of a T-shaped holder 196, which the reed 42 of diverging Shape as described hereinafter. The holder 196 is slidable in the recess 194 for an adjustment of the reed 42 in the vertical direction by means of an adjusting screw 198 is arranged. This set screw passed through the hole of a Approach zoo of the holder 196 goes through it and an adjusting ring 2o2, 204 on each Side of the lug is in the threaded bore of a body 2o6 screwed in, which is attached to the carriage 178 by means of screws 2o8. A plate 21o fastened to the carriage by screws 212 is used for clamping of the holder 196 against the bottom of the recess 194.

As shown in Figs. 18 and 20, the frame of the diverging reed 42, the width of which from its lower to its upper Part increases, inserted into a recess of a frame 2r4 and is in held in place by screws 216. The frame 214 is with the head of the Holder 196 by means of two connections 218, 22o with slot and screw for one Adjustment of the reed 42 in the horizontal direction by means of an adjusting screw 222 tied together. This adjusting screw, which goes through the hole of a lug 224 of the frame 214 and has a collar 226, 228 on each side of the neck into the threaded bore of an extension 23o of the head of the holder 196 screwed in. Springs 232 wound around the shafts of screws 22o and are arranged between the holder 196 and the nut, cause a certain friction, to secure the position of the frame 2I4 and the reed with respect to the holder.

Furthermore, is on the slidable carriage 178 by means of screws 236 a support body 234 is attached as shown in Figs. The supporting body 234 has a recess 238 for receiving a by means of a screw 242 on the Support body attached holder 24o. A link 244 that supports a rod or table 246 carries is slidably disposed on the holder 24o and is inoperative in its normal Position held by a stop screw 248 which is screwed into the holder 240 and a stop for an extension 25o of the link 244 forms. After the termination of the warping process, the link 244 and the table 246 in an upper effective Position 24,1 !, 246 are shifted, as in dash-dotted lines in FIG. 13 is shown to bring the threads of the chain 34 in a straight plane and that To make it easier to stick a strip on the chain before severing the threads will. A spring trigger 252, which is arranged on the link 244, engages automatically into an incision 254 on holder 24o, around member 244 and table 246 in FIG to hold the upper effective position. A stop screw 256 attached to the holder 24o is arranged, limits the upward movement of the member 244 to an undesirable To prevent the member 244 from sliding out of the holder 240.

As shown in Figures 11, 13 and 18, there are two rods 235 and 235 237 made of glass or any other suitable material for guiding the chain 34 is also attached to the carriage 178. For this purpose, two are perpendicular Support bars 239 carrying a link 241 that has one attached to it on each side has horizontal support rod 2q.3, attached to the "on the slidable carriage 178" Frame 234 attached. Arms 245 holding the guide rod 235 and arms 247 holding the Carrying guide rods 237 are rotatably and adjustably attached to the support rods 243. The arms 245 and 247 are held in their positions by fitting screws or the like.

Further, a rheostat mounted on a fixed part of the warping machine and electrically connected to the field of the electric motor 46 through lines 26o is controlled by the slidable carriage 178, as shown in FIGS. 12, 13, 17, 18 and 22. For this purpose, a rack 262, which meshes with a gear 264 keyed onto the shaft 266 of the rheostat 258, is attached to the carriage 178 by screws 268. An upward movement of the carriage 178 by the control device 179, 172, 174, 176 causes a rotation of the shaft of the rheostat 258 as a result of a movement of the swingable carrier 140, I42 and the pressure roller 132 through the angle y during the growth of the winding on the tree, see above that the operating speed of the shaft of the electric motor 46 and the tree directly coupled thereto is automatically reduced from a certain normal value to a lower value in order to achieve a substantially constant running speed of the warp threads, which means a substantially constant tension in the warp threads to the extent as the diameter of the coil 134 grows.

Assume that the adjustable divergent reed 42 is at the beginning of the warping process used so that the chain 34, through a dash-dotted line Line indicated in Fig. 18, between points d and e of the reed passes. While the winding 134 is being formed on the tree, the diameter of the winding increases, so that the chain from a lower level to a higher level, for example from layer 34 'to layer 34 ", as shown in Fig. 17. Simultaneously the swingable carrier 140, 142 carrying the pressure roller 13.2 becomes through the angle y moved so that the slide 178 carrying the reed 42 by the control device 179, 172, 174, 176 is raised by the distance c (see Fig. 13). Preferably are the organs of the control device are arranged and designed so that the lifting of the Rietes corresponds to the chain and the latter always between the two points d and e des Rietes goes through.

As can be seen, the guide rods 235, 237 and with the The table 246 connected to the slide 178 is raised simultaneously with the reed 42. Such a thing Lifting of the guide rods 235, 237 in response to the growth of the winding on the tree switches a change in the angle between the warp threads 34 and these guide rods, so that the tension in the warp threads during operation the warping machine remains essentially constant, resulting in a uniform winding on the tree.

If, after the start of the warping process, the worker should notice that the threads of the chain are not evenly distributed over the width of the tree used in the warping machine, the even distribution of the threads can easily be achieved by a slight readjustment of the reed 42 in the vertical and / or horizontal direction can be achieved by the adjusting members 198, 2o2 and / or 222, 228. When the warping process has ended and the warping machine is stopped, as will be described hereinafter, the pressure roller is in the position shown in FIGS. 11 and 17 in dashed lines. According to FIG. 17, the pressure roller is still located between the flanges of the tree 44. In order to enable the removal of the full tree in the direction of its longitudinal axis, as described above, the pressure roller should also be manually inserted into the solid lines in FIG position shown are swung. For this purpose, a handle 27o is arranged on the arm .1q2 (see FIGS. 11 and 16). During this clockwise swinging of the platen from the position 132 "(Fig. 17), further lifting of the reed 42 and table 246 is undesirable as the chain remains in the same plane. Therefore, adjustable members are provided around the control device 170, 172, 17q., 176 when the pressure roller 132 is moved away from the winding on the tree after the warping process is complete.As shown in Figures 12, 13 and 18, an adjustable fitting screw 272 is on the body 192 to cooperate with a stop 274 attached to the slidable carriage 178. The adjustable fitting screw 272 can be adjusted so that the stop 27q contacts the fitting screw substantially simultaneously when the warper is stopped, for example when the platen and organs the control device are in the position shown in broken lines in FIG. 17, ie when the pressure roller is in the position g 132 "is. If the pressure roller is now moved away from the winding on the tree and the pressure roller and the crank 170 are swung into the position shown in FIG. 17 in solid lines, the carriage 178 and the cam 176 attached to it are stopped by the fitting screw 272 so that the drive member 172 is swung around the pin between this member and the crank 170 against the action of a spring 186, while the roller of the member 172 slides along the surface of the cam 176. The control device 170, 172, 174, 176 is thus made ineffective, and the swinging away of the pressure roller from the tree does not cause any further lifting of the reed and the table. If a winding with a smaller diameter than that shown in FIG. 17 is desired, the position of the fitting screw 272 is changed so that the stop 274 touches the screw 272 after a short stroke. The shutdown members 272, 274 can therefore be set for windings of different diameters. In order to hold the pressure roller 132 in the extreme position shown in FIG. 17 against the action of the weight 164 and the spring 186 during the exchange of a tree, the following automatic locking device is arranged. According to FIGS. 13 and 16, a locking rod 276, which carries two adjusting rings 278 and 28o, is arranged displaceably in fixed bearings 282 and 284. A spring 286 mounted between the bearing 284 and the collar 28o tends to urge the collar against the bearing 282 so that the end 288 of the rod 276 comes into the path of a cam 29o on the crank 17o is attached, which is keyed on the shaft 144. The other end of the spring-loaded locking bar 276, which protrudes from the frame of the warping machine, has a button 292 attached to it. During the warping process of the device, the locking bar 276 is in a plane above the cam 29o. When, at the end of the warping process, the crank 17o and the cam 29o reach the position shown in dash-dotted lines in FIG. 17, the locking bar 276 is still above the cam 29o. If the pressure roller 132 is now moved away from the tree and the crank is swung into the position shown in solid lines in FIG. 17, the inclined surface of the cam 29o contacts the locking rod 276 and moves it against the action of the spring 286, whereupon the spring 286 after the inclined surface of the cam has been released from the locking bar, the locking bar returns to its normal position, now under the cam 29o, so that the locking bar 276 engages with the straight locking surface 294 of the cam 29o and the pressure roller 132 engages holds in its extreme position. In order to release the pressure roller after changing a tree, the locking bar 276 is pulled out against the action of the spring 286 by grasping the button 292. The pressure roller can then be brought back into its starting position, whereupon the locking rod 276 can be released so that the latter is automatically returned to the position above the cam 29o by the spring 286, as shown in FIG.

The warping machine shown in the drawings has a first brake, which is connected to the drive, and a second brake which is connected to the print roller is connected, and there are organs provided to a substantially simultaneous Apply both brakes when the warper is stopped.

According to FIGS. 12, 13 and 14, part of the drive head 5o, which is keyed onto the shaft 52 of the electric motor 46, is designed in the form of a brake drum 294. One end of a brake band which loops around this drum is fastened to a solid body 298, the other end of this brake band to an arm 3oo of a double-armed lever 3o2 which is rotatable on the body 298 at 304. A tension spring 3o6, which is stretched between the other arm 3o8 of the double-armed lever 302 and an extension 31o @ of the fixed body 298, tends to rotate the double-armed lever 3o2 counterclockwise, as can be seen in FIG to keep the brake released. The counterclockwise rotation of the lever 3o2 is limited by a nose 312 of the lever 302 , which can abut against a protruding part of the fixed body 298. The arm 3oo of the lever is hinged to one end of a connecting rod 314, the other end of which is rotatably connected to the core 316 of a solenoid 318 in a conductive manner with the electrical brake controls to be described hereinafter. Excitation of the solenoid 318 causes the lever 3o2 to move clockwise to apply the brakes 294, 296.

13 and 14, a ring 32o of leather or some other suitable material is attached to the surface of the brake drum 294 toward the flange i2o side of the tree. When a tree is inserted into a warping machine, the flange i2o is pressed against this ring 320 , so that the ring cooperates in driving the tree by means of friction.

As shown in FIGS. 13 and 16, a brake drum 322 is mounted on a hub 324 of the replaceable platen 132 . When the pressure roller is inserted into the bearings on the support arms 140, 142, a braking band 326 can be wrapped around the drum 322 . One end of this brake band 326 is connected to an extension 328 on the arm i4o, the other end of this brake band is connected to one end of a compensating element or a tension spring 33o, the other of which is connected to a crank 32 2 which is mounted on a bearing 336 of the Arm 140 mounted shaft 334 is keyed. A tension spring 338, which is tensioned between a pin 340, which is arranged on the arm 14o, and an arm 342 which is keyed on the shaft 334, tends to move the crank 332 clockwise, as shown in FIG. 13 can be seen to keep the brake in the released position.

The first brake 294, 296, which is connected to the drive of the warping machine, and the second brake 322, 326, which is connected to the pressure roller, are coupled to one another by a Bowden cable 344. One end 346 of this Bowden cable is attached to the arm 3o8 of the double-armed lever 302 , while the other end 348 is connected to the arm 342. An excitation of the solenoid 318 thus causes the first brake 294, 296 to be applied and, at exactly the same time, the second brake 322, 326 to be applied by the Bowden cable and the tension spring 33o, which compensate for the differences in the brakes. On the other hand, if the solenoid 318 is de-energized, the lever 302 can be moved counterclockwise by the spring 3o6 for an automatic release of the two brakes. Of course, any other coupling could be arranged between the two brakes and any other balancing device between the two brakes, if desired.

As explained above, the rheostat 258 serves to provide an automatic Reduction of the operating speed of the drive motor 46 from a certain normal Value to a lower effect, so that a substantially constant running speed of the warp threads, which result in a substantially constant tension of the threads is reached during operation of the warping machine. The normal running speed of the chain thread is determined by the normal operating speed of the electric motor determined at the beginning of the warping process. Different threads of different strengths and / or different material require different running speeds in order to to get the right tension in the threads. Therefore there is a additional electrical setting element or a hand rheostat35o (see Fig. ii and i2) for setting this specific normal operating speed of the drive motor 46 arranged.

It has been found that a further speed range can be obtained directly with the drive 5o of the tree by using a direct current motor and by connecting the hand rheostat 350 to the power source for direct current, such that the rheostat 35o the voltage of the direct current supplied to the electric motor of the warping machine controls.

Referring to Fig. 23 which is the circuit diagram of the electrical The warping machine equipment is the motor converter for alternating current in direct current 26 with alternating current from a power source (not shown) the lines 3o fed when the manual switch 354 is closed. The generator of the Motor converter 26 generates the direct current. Terminal 358 of generator 356 is with the terminal 36o of the electric motor 46 of the warping machine through the line 362 connected, which contains the electromagnet 364 of the iMotorfeldrelais 36; 6. the clamp 368 of the generator 356 is connected to the terminal 37o of the electric motor 46 through the line 3712 connected, which contains the pole MI of the three-pole main switch M through the tripping magnet 374, the solenoid 376 of an overcurrent switch 378 and the Field 38o of the electric motor 46 is controlled.

As can be seen from the above, the electric motor 46 of the warping machine is started as soon as the pole 111 of the main switch 117 is closed when the release magnet 374 is excited. This trip solenoid can be energized by depressing the start button 3812 , which can normally be held in its open position by the action of a spring (not shown) and is located in the following engine starting circuit: A lead 384 leads from the right terminal of the start button switch to the left terminal of overcurrent switch 378, the right terminal of which is connected to tripping magnet 374 by line 386. A line 388 leads from the tripping magnet 374 to the movable finger 390 of the automatic motor field rheostat 258, which is controlled by the control device 170, 1,72, 174, '176, as described above. The coil 39'2 of the automatic rheostat 258 is connected to one end of the field 394 of the electric motor 46 by a line 396. The other end of field 39.1. is connected to the left terminal of the crank button 382 by a line 398. This motor starting circuit is provided by the exciter 456 of the motor converter 26 through a line 452, which connects the terminal 454 to a connection point 448 in the line 38a, and through lines 462 and 478, which connect the terminal 458 to a connection point 476 in the line 398, Electricity supplied.

When the trip magnet 374 is energized by completing the above-described circuit through the spring-loaded start button 382, the pole M? of the main switch M is closed, whereby a 1-Ialtestromkreis for the tripping magnet of the main switch is closed, as will be described below, so that the main switch remains in the closed position when the spring-loaded starter button is subsequently released. The holding circuit runs, starting from the left terminal of the starter push button switch 382, as follows: line 398, field 394, line 396, rheostat 258, line 388. Tripping magnet 374., line 386, bridge of the overcurrent switch 378 and line 40o, which is the left terminal of the Overcurrent switch 378 connects to the left terminal of the starter push button switch 382, the line 4oo containing the pole 1f, the main switch 11, the switch 4o2 of a counter stop relay 404, the switch 4o6 of a chain brake relay 408, the electromagnet 410 of a time relay 412 and a stop pressure button switch 414, the normally held in the closed position by a spring (not shown).

The main switch! 1f is opened, and the supply of the electric motor 46 with: Direct current is interrupted at the pole 1111 as soon as the one described above Holding circuit of the release magnet 374 either at the push button switch q! 14 or at switch 4o6 of the brake relay 408 or at switch 4o12 of the counter relay 404 is interrupted. The opening of the pushbutton switch q: 14 takes place when the warping machine is stopped by hand; finds the opening of switch 4o6 instead of when one or more thread monitors 41-6 fall in the gate and a control circuit close as a result of a thread break, and the opening of switch 40.2 takes place, when the normally closed switch 418 of interrupt counter 98 after the execution of a certain number of revolutions of the tree is opened, as described hereinafter.

Each of the above-mentioned interruptions in the holding circuit of the release magnet 374 causes the brake solenoid 3118 to be energized for an immediate application of the brakes of the warping machine. The solenoid 318 is arranged in the following circuit: A line 42o, branched at point 422 from a first line of the AC supply line, leads to the switch 424 of the timing relay 412 and thence to one end of the solenoid 318. The other end of the solenoid 318 is connected to junction 4126 on a second line of the AC power line by line 428 containing switch 430 of a solenoid brake relay 432. A controllable choke coil 433 is arranged in parallel with the switch 424 by a line q: zl, from which the line q:? O branches off. The electromagnet 434, which controls the switch 43o of the solenoid brake relay 432, is arranged in the following circuit: line 436, which leads from the electromagnet 434 to the connection point 438, line 38e8 from this connection point 438 to the trip magnet 374, which is part of the Line 388, which leads from the release magnet 3174 to the connection point 440, and line 4422, which connects this connection point 44o to the electromagnet. As soon as the holding circuit of the release magnet 3774 on the push button switch 414 or the switch 4o6 or the switch 4o2 is interrupted, the described circuit containing the electromagnet 434 is also interrupted, so that: the electromagnet 434 is de-energized and the switch 430 is closed. At the same time, the electromagnet 410 of the timing relay arranged in the holding circuit of the tripping magnet 374 is also de-energized. As a result of the delay effect of the timing relay 4r2, the switch 424 remains in the closed position 424 shown in dashed lines for a short period of time, for example 2 seconds, so that the circuit of the brake solenoid 318 is closed and the latter a strong application of the brakes of the warper caused as soon as the electromagnet 434 of the solenoid brake relay is de-energized and the switch 430 is closed. After this short period of, for example, 2 seconds, the switch 424 of the de-energized time relay 412 moves into the position shown in solid lines, so that now the controllable throttle coil 433 is switched on in the circuit of the brake solenoid 318, whereby the de-energizing of the brake solenoid is automatically activated is reduced to a certain extent in order to cause a weak application of the brakes of the warping machine. After a brief period of strong application of the brakes to effect an immediate stop of the tree, the brakes are weakly applied until the motor 46 is stopped. As soon as the motor is started again, the electromagnet 434 connected in parallel to the release magnet 37.4 is energized, so that the switch 430 is opened and the brake solenoid 318 is de-energized for an immediate release of the brakes of the warping machine. The above-described weak application of the brakes of the warping machine while the motor 46 is at a standstill can be controlled by the choke coil to such an extent that, although it allows part of the winding to be unwound from the tree by the storage device 22, it prevents the tree from rotating further as soon as the storage device has been stopped for the completion of the unwinding process. However, if so desired, line 42z and choke coil q.33 can be omitted. Under these circumstances, the solenoid 318 would de-energize as soon as the switch 424 of the timing relay is in the open position, ie the brakes of the warping machine would be released after a short period of application, corresponding to the delay effect of the timing relay.

The hand rheostat 35o for setting a certain normal operating speed of the electric motor 46 by regulating the voltage of the direct current supplied to the electric motor is arranged in the following circuit: A line q: 44 leads from the end 445 of the coil 446 of the generator field rheostat 3.5o to the pole 1b13 of the Main switch 117, which in turn is connected to the connection point 448 in the line 388 by a line 450. A line 452 leads from this connection point 448 to the terminal 454 of the exciter 45.6 of the motor converter 26. The terminal 458 of the exciter 456 is connected to one end of the field 46o of the direct current generator 356 by a line 462. The other end of the field 46o is with the movable finger 46.1. of the hand held relay 35o through a line 46'6 containing the switch 46S of the relay 408. The end 447 of the coil 448 of the hand rheostat 35o is connected to the connection point 470 in the line 46.2 by a line 472 which leads to the connection point 474, through the part of the line 398 which connects the connection point 474 to a connection point 476, and by a line 478 connecting connection point 476 to connection point 470. As can be seen from the circuits described, the generator field 46o is excited by the exciter 4.56, which generates a constant potential. This potential is applied to a circuit which consists of the left part (as can be seen from FIG. 23) of the generator field rheostat 350 in parallel with the generator field 4: 6o and the right part of the generator field rheostat 350 in series with these. A movement of the finger 464 over the hand rheostat 35o causes a change in the potential imposed on the generator field 46o and consequently a change in the current flowing through this generator field during normal operation of the warping machine. For example, if the finger is 4.64. is moved to the right, the excitation of the generator field and the current flowing through this field are increased. Therefore the current flowing through the generator field corresponds to the setting of the finger .1164. of the hand rheostat 350. This current, when it is high, results in a high voltage produced by the generator 3.3 (FIG. 13), when it is low, a low one.

The normal high operating speed of the electric motor 46 at the start the warping process is controlled by the voltage of the direct current supplied to the electric motor determined, and therefore the normal high operating speed of the electric motor can easily can be set by the hand rheostat. The automatic one, in series with the Field 394 of the electric motor 46 switched rheostat 258 is used to reduce the Speed of the electric motor from this normal value to a lower value, so as to have a substantially constant tension in the threads and / or accordingly to maintain a constant speed during the warping process, as above was set out.

Under certain circumstances it is a very low speed or a so-called. Slow running of the electric motor 46 is desirable. First, for example after the Occurrence of a thread break in the creel and the knotting of the ends of the broken thread without the use of a storage device or secondly, after the occurrence of a thread break at a point between the gate and the tree and tying the broken ends of the thread together after unwinding one Part of the chain from the tree through the storage device. In the first case, it should the chain can be pulled out of the gate at a very low speed until it is slack of the thread is resolved, and in the second case should be the one in the storage device merged chain by the building with very low speed during the decline of the gripping member 4o by the reversing motor 48o from its lower effective position will be included in its upper ineffective until the chain is through the storage device is released.

As described above, the electromagnet q.82 of the relay 408 is energized in both of the above-mentioned cases, so that the switch 468 is opened and the hand held switch 350 is switched off from the generator field. 23, a low speed resistance is 4.8q. arranged between the connection points 486 and 4.88, so that after the described disconnection of the manual rheostat 35o from your generator field 4.6o, the current now flows through the following circuit: exciter 456, line 4612, generator field 46o, line 466, rheostat 4.54., - line: 144 ., Pol 1173, lines 450, 452. Under these circumstances, therefore, the combined resistance of the generator field 46o and the Reg ehviderstandes 4.84., Which are connected in series, flows through the generator field, which causes a power flow that the for the very low speed and torque of the electric motor 46 causes the required low voltage. It may be mentioned that this flood of force, and therefore the voltage and the torque, are independent of the setting of the hand rheostat 350 , since the latter is disconnected from the generator field 4.6o. On the other hand, the hand rheostat 350 is again connected to the generator field 46o and further operation of the electric motor 4: 6 at slow speed is made impossible as soon as the electromagnet 4.82 de, relay 4.o8 is de-energized, so that switch 4.68 is closed. In the first case, the electromagnet _l82 is de-energized as soon as the control circuit containing the thread monitors -1..6 in the gate is interrupted after the slack in your previously knotted thread has been eliminated. In the second case, the electromagnet 1482 is de-energized as soon as the switch 49o, which is opened by an element 49i which is arranged on the movable gripper 4o of the storage device, when the gripper of the storage device is returned to its upper inoperative position. Furthermore, in order to fully understand the operation of the electric motor 46 at low speed in the second case, the following arrangements should be mentioned: an auxiliary starter switch 482 controlled by an element 493 and a control switch 494; controlled by a member 495 mounted on the mobile gripper 4o of the storage device in series in a circuit containing the main switch M for starting the electric motor are arranged; The control element 493 of the auxiliary starter switch, 4gz of the electric motor 4! 6 is mechanically coupled to the reversing switch 49.6 for the reversing motor 48o of the storage device so that it causes the auxiliary starter switch 492 to close when the reversing switch for an upward movement of the gripper 4o is switched on by the reversing motor .

In view of the foregoing, in the first case, ie in the case of a thread break in the gate, slow running of the electric motor 46 is obtained by depressing and holding the spring-loaded starter pushbutton 382; As soon as the slack in the previously knotted thread has been eliminated and the control current containing the thread monitor 416 is interrupted, the electromagnet 482 of the relay 4o8 is de-energized and the switch 46o is closed; whereby the hand rheostat 350- is again connected to the generator field 46o, so that the speed of the electric motor 46 increases to its set value and the electric motor continues its operation at high operating speed. In the second case, that is, in the case of using the storage device, the electric motor q: 6 works at low speed as soon as the reversing switch 496 for upward movement of the gripper 4o, which is mechanically coupled to the control element 493 of the auxiliary starter switch 492, is switched on until the circuit containing the main switch M is switched on the control switch 494 is interrupted during the upward movement of the gripper; the electric motor 46 can be started again at its operating speed by depressing the starter pushbutton 38.2 as soon as the slow-speed switch 49o has been opened after the return of the gripper to its upper inoperative position, whereby the electromagnet 482 of the relay 4o8 is de-energized and the switch 46.8 has been closed in order to reconnect the hand rheostat 350 to the generator field 46o.

As can be seen from the description of the warping machine, the The warping machine has the following features: The bracket 5,6 carrying the loose head 8o is adjustable placed on the poles 64 so as to accommodate trees of different widths to allow the platen -z32 to be interchangeable so as to allow the selection of a platen to allow that can work with a tree of certain width; the diverging reed 42 is adjustable in the horizontal and vertical directions. Therefore, the warping machine can be used to wind threads of different strengths, d. H. the number of threads per centimeter used on trees of different widths as will be explained hereinafter in connection with Figs. 24-26.

If, for example, the warping machine has previously been used for warping threads with a thickness of about twelve threads per centimeter on a tree with a width of about 250 mm, and when the warping machine is used during the next warping process for warping threads with the same thickness of about twelve If threads per centimeter are to be used on a smaller tree with a width of about zoo mm, proceed as follows: It is assumed that the tree 44, the bracket 56 with the loose head 8o and the reed 42 are during the previous warping of the Thread on the 25o. Mm tree in the position shown in solid lines in Fig. 24, and a chain of three hundred threads passes between points f and g of the reed. Now the bracket with the loose head is brought into the dot-dash position 56 ', 8o' in order to allow the insertion of a 20, 0-mm tree 44; the motor 46 and the drive head 5o coupled to it remain in their position. A pressure roller that can work with a 2ioo-mm tree is used for the pressure roller previously used. The reed 42 remains in its position. Sixty threads are removed from the chain so that only a chain of two hundred and forty threads will pass between points f and m of reed 42, these points being zoo mm apart. Hence the. Tree zoo mm wide on two hundred and forty threads per zoo mm, or, in other words, the threads are wound on the 200 mm tree at the same strength of twelve threads per centimeter as they were before on the 25o mm tree have been wound up.

The pressure roller is not changed. The reed 42, however, is brought into position 42 ', as shown in FIG 25 is shown in dash-dotted lines, so that point h takes the place of point f and point i takes the place of point g. Furthermore, fifty threads are removed from the chain in the space between points i and k , so that a chain of two hundred and fifty threads will pass between points la and i of the reed in position 4.2 ', the points being 25.0 mm apart, hence the tree will take two hundred and twenty-five millimeters wide fifty threads on it, or, in other words, the threads are now wound around the tree at a thickness of ten threads per centimeter. In order to move the reed from the extended position 42 to the dot-dash position 42 ', the reed is first displaced in a vertical direction Y (see FIG. 26) so that it comes to the intermediate position 4: 2', as shown in dashed lines Lines is shown, whereupon the reed is moved from this intermediate position 4i2 "into the new position 42 'in a horizontal direction Z. Of course, the horizontal and vertical adjustment of the reed could also be reversed, if desired, or take place simultaneously.
