In addition, the device shown summarizes the threads in the embodiment into two strands and winds the strands underneath the rotatable pull-out arrangement with the selected String voltage on. This strand tension is normally less than the sum of the tensions of the individual threads or filaments above the rotating pull-out assembly. The pull-out arrangement for the threads is located between one Take-up assembly and the source of the molten glass streams from which the glass filaments are drawn. To this Way isolates or separates the pull-out assembly resulting from the thread formation tension in the threads above the Extraction arrangement of the threads which are wound up as strands below the extraction arrangement. A dedicated apparatus leads in this context a predetermined and selected voltage, which is normally in the range between 30 to 200 g moved, into the glass strands between the thread extraction arrangement and the winding arrangement.

The winding arrangement in turn adapts the winding speed of the strands to the speed at which the extraction arrangement feeds the strands of the winding arrangement.

The illustrated embodiment shows the winding of two packs; of course, devices can be used that only wind one pack or that are able to wind more than two packs.

In Figures 1 and 2, a feeder 10 is shown, containing a body of molten glass. The feeder 10 can continuously supply several molten glass known species are fed. For example, catfish may be supplied with molten glass from a forehearth to feeder 10 which comes from an oven, the batch materials

heated to molten glass. A melting device can also be assigned to the feeder 10 and feed molten glass to it, by bringing glass spheres into a heat softening state. Connections 12 are provided at the ends of the feeder, which connect the feeder 10 to a source of electrical energy in order to carry out a conventional resistance heating. Such a heater keeps the molten glass in the feeder 10 to suitable viscosities and thread-forming temperatures. The feeder 10 has a bottom portion 14 with openings or passages for flowing streams 16 of molten glass from the feeder 10 release. As shown in FIG. 1, the openings on the bottom part 14 of the feeder are formed in front of them downwards extending, bored projections or tubular elements 18 -, =.

Usually the feeder 10 consists of platinum or a platinum alloy. .

The molten glass streams 16 become individual downwards Continuous single glass filaments 20 drawn out. Below the The collecting shoes 22 and 2.4 arranged in the feeder 10 collect the continuous glass threads 20 into two bundles or strands 26 or 28 together. .

Other arrangements typically coat the filaments 20 with both water and a liquid size or other protective coating material. As shown, nozzles 30 and 32, adjacent to the bottom part 14 of the feeder ΙΟ, direct a water spray onto the continuous glass filaments 20 ₁₇ before the collecting shoes 22 and 24 combine the filaments into glass strands 26 and 28. ·. .

One in a housing 38 directly above the collecting shoes 22 and 24 arranged sizing applicator 36 brings a liquid

Plain or another covering material on the rapidly passing continuous glass threads. The applicator can be any shape known in this context; in the exemplary embodiment, however, there is the applicator from an endless belt which is guided through the liquid contained in the housing 38. When the continuous glass threads 20 at high speed in touch contact across the surface of the moving, from an endless belt or If you run over the existing applicator 36, some liquid will be added transferred from its surface to the threads.

A pull-out wheel 40 pulls the continuous glass threads 20 with it constant velocity from the molten glass streams 16 originating from the feeder 10 and also dilutes them this way. The pull-out wheel 40 is rotatably arranged in a housing 42 directly below the collecting shoes 22 and 24. Within A motor 44 is arranged in the housing 42 and rotates the pull-out wheel at a constant high angular speed. In the exemplary embodiment, the motor 44 consists of an induction motor.

The pull-out wheel 40 usually measures about 30 cm in diameter; the motor 44 can pull the pull-out wheel 40 sufficiently fast rotate to cause the continuous filaments 20 of the streams 16 to rotate at linear speeds up to 3.6 km per minute and can be withdrawn faster. As in Figures 1 and As shown in Fig. 2, the strands 26 and 28 pass from the collecting reels 16 and 24 over an alignment shoe 56 for the strands which are over has the circumference running grooves 48 and 49 and then come into contact with a smooth circumferential surface 45 of the pull-out wheel 40. The alignment shoe 46 aligns the paths of the running strands so that they are spaced from one another but mutually parallel over the smooth circumferential surface 45 of the pull-out wheel 40 run, the strands are essentially

309826/0298

parallel to the center line of the circumferential surface of the pull-out wheel 40 arranged. In the illustration of Figure 1, the strands 26 and 28 come somewhat to the right of a vertical center line of the Pull-out wheel 40 with this in contact and leave the pull-out wheel on the left hand of the center line.

The alignment shoe 46 is located above and slightly behind on the right with reference to the pull-out wheel 40. Starting from the pull-out wheel 40, the strands 26 and 28 initially run upwards and then again from the upper point of a coil or a roller 54 to below, which is rotatably mounted at the end of a lever 56. The lever 56 is pivotably arranged on the housing 42. In the figure roller 54 and lever 56 are arranged slightly above and slightly offset to the left to the pull-out wheel 40. A spring 58 within of the housing 42 biases the lever 56 in a counterclockwise direction, as FIG. 1 shows. The biasing force of the Spring 58 introduces a selected tension in the strands 26 and 28 passing therethrough. This introduced voltage is chosen so that the Zuifbau a desired stable, coiled Pack is possible.

The locations of the alignment shoe 46 and the roller 54 are chosen so that a non-sliding operative connection between the wet strands 26 and 28 running through and the circumferential surface 45 of the pull-out wheel 40 moving at high speed takes place and is favored. Usually is coverage of the strands over about 60 to 80% of the length of the circumferential surface 45 is sufficient to be non-conductive Contact between the surface 45 and wet strands 26 and ensure. The angle A shown in Figure 1 represents the angular detection of the strands 26 and 28 along the circumferential Surface 45 of the pull-out wheel 40. The angle A is normally about 240 to 300 °; an angle of

between about 250 and 280 ° is normally preferred for pull-out wheels that have a diameter between about 28 to 32 cm exhibit. In order to continue to promote a non-sliding gripping between the wet strands 26 and 28 and the pull-out wheel 40 and to guarantee, an annular coating 60 made of polyurethane is used for the illustrated pull-out wheel 40. This layer 60 forms the soft, circumferential surface 45 of the pull-out wheel 40. Occasionally, can In this context it can be useful to check the surface finish, i.e. the circumferential surface to roughen the contact between the surface and the wet. Improve strands.

The diameter of the pull-out wheel 40 and the improved, non-sliding detection of the Threads overall favors those still within a non-slip of the threads lying extraction capacity of the extraction wheel 40, which can be used in thread-forming processes with thread-forming tensions up to 700 g and even more. The thread-forming tension is the totality or the total sum the tensions of each filament 20 above the applicator 30th

The pull-out wheel 40 guides the strands 26 and 28 at a constant linear velocity of the strands below Take-up assembly 70 to. The strands then run from the pulley wheel 40 over the roller 54 and other strand straightening shoes 62 and 64 for take-up assembly 70.

The winding assembly 70 winds the strands 26 and 28 as substantially identical wound packages 72 and 28 on collecting spools. These collecting coils are shown as tubes 76 and 76, which telescope over a spindle and a Winding head are pushed. A drive within the winder

Order 70 rotates the spindle 80.

Traversing arrangements or transverse guide arrangements 82 for the strands on the winding arrangement 70 guide the strands reciprocally forwards and backwards in the longitudinal direction to the packages 72 and 74 back and forth to distribute the passing strands onto their respective packages during package build. The strand movement caused by the transverse guide arrangement 82 is a coordination of a fast primary strand reciprocation and a slower secondary strand reciprocation. and float.

For a better understanding of the structure and mode of operation of the strand transverse guide arrangement 82 reference is made to FIGS. 1 to 4. The transverse guide arrangement 82 comprises strand guides 88, the. are held in a spaced position by storage adjacent packages 72 and 74. The guides 88 slide longitudinally in a slot of a horizontally extending tubular, with a cam guide provided bearing housing 90 which extends from the frame 92 of the winding assembly 70. In the bearing housing 90 are identical, coaxially interconnected, cylindrical or «, drum-shaped cam guides 96 are rotatably mounted and have guide grooves 98 on their surface. The beach tours are connected to the guide grooves 98 of the drum-shaped cam guides 96 via cam followers 100. When the cam guides 96 rotate, then the strand guides 88 travel along the slot in the bearing housing 90 in the longitudinal direction of the spindle 80 (and packs 72 and 74) back and forth. As shown, the bearing housing and strand guides extend 88 with the cam guides 96 coaxial with one another, the bearing housing 90 also extends in a direction parallel EU to the spindle 80, its axis being in the same horizontal direction Level as the axis of the spindle 80 is located (see Figures 1 and 2).

As shown in FIG. 4, the strand guides 88 are hook-shaped at their ends in order to close the strands 26 and 28 grasp and hold onto.

As the cam guides 96 reciprocate the strand guides 88, the strand guides guide the strands 26 and 14 28 in the longitudinal direction to the winding packs 72 and 74 also back and forth. The winding assembly 70 further includes a drive assembly, consisting of motor and coupling 102 within the frame or winding housing 92. The drive arrangement causes the rotation of the cam guide 96 and the rotation of the spindles 80 with controlled speed ratio. This relationship is determined by the desired pack shape and cem Packing structure.

The drive 1 and 2, consisting of motor and clutch, comprises an electric motor 104 rotating at constant speed, which rotates the rotor of an associated eddy current clutch 106. The output shaft of the eddy current clutch 106 is labeled with the suffix 108 provided. Magnetic forces within the eddy current clutch 106 transmit the torque from that of the motor 104 driven rotor on the output shaft 108. In the present embodiment, the electric motor 104 an induction motor.

The motor and clutch drive 102 is a variable speed drive. The speed remains in operation of the motor 104 constant; Changes in the flux density (magnetic forces) within the eddy current clutch 106, however, change the proportion of the constant speed motor on the output shaft 108 transmitted rotary energy. The greater the flux density, the greater that transmitted to the output shaft 108 Percentage of engine power. The drive 102 rotates the spin

del 80 via a non-sliding belt 110 connecting the output shaft 108 to a spindle drive shaft 112 above the drive 102 connects. The rotating drive shaft 112 for the spindle then rotates the spindle 80. The shaft 112 is coaxial arranged to the spindle 80 and is rotatably mounted in a bearing arrangement 140. . ..

Rotational energy from the spindle drive shaft 112 also moves the cross guide assembly 82 via non-slip belts 116. and 118. The belt 116 connects the spindle drive shaft 112 to a rotatably mounted idle shaft 119 of a Intermediate assembly 120. The belt 118 connects the idle shaft 119 to a cam drive shaft 124 which is connected to the cam guides 86 is connected and this is set in rotation. The cam drive shaft 124 is coaxial with the cam guides 96 arranged and is rotatably mounted in a bearing assembly 126, as well as still still in the vertical end plate 128 of a movable Carriage 130.

As well as the packs 72 and 74 on the rotating spindle 80, the diameter of each of these packs increases. Increased for any given angular velocity the spindle, an increase in the package diameter, the speed of the peripheral surface of each of these packages 72 and 74. Therefore, the strand winding speed would increase with increasing package diameter, in the event that there was no compensating Reducing the angular speed of the spindle 80 would occur. .

Accordingly, means for monitoring and controlling the angular speed of the spindle 80 are therefore provided to during During the winding process, an increasing strand winding speed can be traced back to the increasing package diameter to compensate. As shown, the spindle speed is modified accordingly via the drive 102 Regulation. Such a regulation has the effect that a strand winding speed is maintained, which is equal to the constant strand feed speed of the rotating pull-out wheel 40 during the build-up of the packages 72 and 74.

FIG. 5 shows a general block diagram according to an exemplary embodiment of the invention to illustrate the regulation of the angular speed of the spindle 80. In the exemplary embodiment A regulator 140 changes voltage signals to the eddy current clutch 106 are fed to the rotational speed of the spindle 80 during the winding of the packages 72 and 74 control. A part of the controller 140 supplies a control signal which has a pattern-like change value and is effective in such a way that / the speed the spindle modified via the coupling 106. The controller receives voltage signals from a scanning Converter 142 is supplied as well as a constant DC voltage signal from a suitable DC voltage source, for example a battery 144.

The signals from transducer 142 represent those that are sampled Differences between the linear strand feed speed and the linear strand winding speed Such signals from the converter change the pattern-like change value of the control signal in order to

309826/0298

A 39 842 m

speed of the actual feed speed of the strands adapt. The changing output voltage of regulator 140 then controls the magnetic strength of the eddy current clutch 106 to adjust the strand winding speed of the strand feed speed actually and effectively adapt as the packings 72 and 74 increase in diameter. To achieve To improve the stability of the controller 140, feedback voltage signals are still fed to it from a tachometer 146; these tachometer signals provide a measurement of the actual angular velocity of the clutch output shaft 108 (and therefore the spindle 80). ^

The winder assembly 70 senses the angular speed of the spindle 80 as a measure of the package structure or the size of the packages during the winding process and includes means that respond to the sensed angular velocity to then effectively remove the strand transverse guide assembly from the To move the spindle 80 away so as to keep the transverse guides in a predetermined ratio during package build-up to adhere to their respective assigned packs. The cross guides 88 provided with hooks move them into operative connection standing strands 26 and 28 and carry them with you when the hooks move during package assembly with storage move. A control or control of the relationship between the packs 72 and 74 and the transverse guide arrangement is beneficial better string control during the pack construction and thus also an improved pack construction itself.

As can be seen more precisely from FIGS. 2 and 3, is the carriage 130 movable on the winding arrangement 30? the bearing housing 90 for the cam guides 96 is from the carriage 130, therefore the bearing housing 90 moves with the carriage 130. Bearing housing 90 and carriage 130 move horizontal.

As shown, the carriage 130 additionally includes a base portion 190 to the vertical side plate 128. The carriage 130 slides longitudinally on two parallel bearing rods, viz the rods 192 and 194, which are made stationary with respect to the winding assembly 70. These rods extend through Passages in the base 190; the passages extend in a direction perpendicular to the axis of the spindle 80 or the Packs 72 and 74. Therefore, the carriage 130 and bearing housing 90 are in a horizontal plane towards the spindle and movable away from the spindle 80 in a direction perpendicular to the spindle axis. The winding housing 92 of the winding assembly comprises thereby an elongated opening 191 which enables movement of the transverse guide arrangement 92 and thus of the bearing housing 90.

FIGS. 6 to 9 show the controls and mechanisms which are provided for positioning the carriage 130 during the pack assembly in order to maintain a predetermined spacing ratio between the packs 72 and 74 and the transverse strand guides 88, ie a certain distance between the two. A switch 198 completes the control circuit. The switch 198 can be closed manually or automatically to complete the control circuit in order to then start the control when the spindle 80 has reached its operating speed at the beginning of the pack construction. As can be seen from FIG. 6, a battery 200 supplies a constant positive direct voltage to a potentiometer 202. The output voltage of the potentiometer 202 is passed on to a summing node J ^ via a line 104. A rectifier is used to rectify the alternating voltage signals originating from the tachometer 146 208 is provided, which supplies a negative DC output voltage via the line 210 to the junction point J _3. If the voltages applied to junction J ₃ are in imbalance, then

309826/0298

A 39 842 id

The junction point J- forwards an electrical voltage signal via an output line 212 and via the switch 198 to a solenoid or its winding connected to ground on the other side, or to an electromagnet 216, which then closes a normally open switch 218; ^ switch 218 is therefore a 'working contact. This switch 218 is arranged in a circuit which supplies a motor 220 with electrical energy; the electrical energy is supplied via the connection points L ₃ and L. from a suitable energy source. The motor 220 is energized when the switch 218 is closed. When the motor 220 is switched on, it simultaneously drives the grinder of the potentiometer 202 and actuates a drive system which moves the slide 130.

If the voltages from potentiometer 202 and tachometer 146 are the same, however, there is no electrical output signal at junction J ₃ ; therefore, the engine switch 218 remains in its open position. If the voltage drops from the tachometer 1.46, due to the decreasing output angular speed of the clutch 106. then the solenoid coil 216 is energized by the higher voltage at junction J, which comes from the potentiometer 202. The coil 216 of the solenoid closes the motor switch 218, this causes the wiper of the potentiometer 202 to move so that the potentiometer output voltage is reduced until this output voltage is equal to the output voltage of the tachometer 146. Then the solenoid drops out again, ie it is de-energized and the motor switch 218 opens to stop the motor.

Figures 7 and 8 show the position control for the strand transverse guide in greater detail; this position control is located in a control housing 224 which is mounted on the base part 190 of the slot 130. Close to the obexan

The electric motor 220 is mounted at the end of the control housing 224 and has a V-belt pulley 226 on its output shaft 228. Below the motor 220 is in the control housing 224 the potentiometer 202 built in with a V-belt pulley 230 on the shaft 232 for the actuation of the potentiometer wiper. In the lower area of the control housing, the slide drive is provided, which has a rotatable drive worm comprised in a threaded passage

is arranged in the base 190 of the carriage 130. A non-threaded portion 242 of the drive spindle or worm 236 carries pulleys 244 and 246.

The switched-on motor 220 rotates the drive spindle 236 and moves the wiper of the potentiometer 202. For this purpose, the Motor output shaft 228 and drive screw 236 are connected by a belt running in pulleys 226 and 244. Another belt 252 runs in pulleys 2 30 and 246 and connects the drive spindle to the grinder of the Shaft 232 of the potentiometer.

With one revolution of the motor 220, the shaft 232 and the drive spindle 236 are rotated. The rotating drive spindle 236 moves the carriage 130 from the spindle 80 and away from the slowly building up packs until the potentiometer output voltage is equal to the voltage of the Tachometer 146. The solenoid coil 216 is then de-energized and the motor switch 218 opens to turn off the Engine 220.

A supervisor can set a desired position in relation to the relationship between the strand guides 88 and the lap packages Select 72 and 74. Since the spindle speed is regulated at the beginning of the pack build-up and is therefore known the supervisor can adjust a trim potentiometer 260 to balance the voltage of potentiometer 202 with the voltage of the speedometer 146 now beginning to bring. The supervisor then moves the bearing housing 90 (and thus the carriage 130) for positioning the transverse guides 88 in a selected position. Such Movement also moves the wiper of potentiometer 202. Therefore, the operator only turns on the trim potentiometer 260 in order to provide a voltage at potentiometer 202 at the beginning of the package construction which is equal to the Speedometer voltage.

The idler assembly 120 allows the carriage to move 130 without breaking or damaging drive belts 116 and 118. As shown, idler assembly 120 includes a rotatable one Idle shaft 119, a bearing housing 270, a steep arm 272, bearing element 274 and a bearing bracket 276..

The bearing element 274 and the bearing bracket 276 hold the bearing housing 270 and the idle shaft 119 above the carriage 190. With the help of rocker arms 277 and 278, the bearing housing 270 movable about the axis of the bearing element 274.

The actuating arm 272 connects the idle shaft .119 and the drive shaft 124 for the cam drive with each other to these two shafts at a predetermined constant distance for the Belt 118 to hold. The actuating arm 272 pushes (swings) the idle shaft 119 around its bearing housing 270 upwards around the Axis of the bearing element 274, which is formed like a wave when the carriage 130 is in the direction of the spindle

emotional. The opposite occurs when the slide 130 moves away from the spindle 80.

The oscillating movement of the idler assembly 120 keeps both belts 116 and 118 in a driving operative connection their associated pulleys.

The winding arrangement 70 also ensures the slower transverse strand guiding movement by means of a device for guiding back and forth of the bearing housing 90 is provided. This device comprises a motor 280 (see Figure 2), spur gears 282 and 284, a cam track 266 and a cam follower 288. In the illustrated embodiment, the cam track exists 286 of a cam wheel mounted on a rotatable shaft 290. The motor 280 rotates the cam wheel 286 via one another meshing spur gears 282 and 284. The cam follower 288 includes a pin 292 which is provided with a circumferential Recess 294 of the cam wheel 296 is in operative connection. The cam follower 280 is mounted on the drive shaft 224 for the cam drive. When the rotatable shaft 290 rotates the cam wheel 296, it imparts to the cam follower a back and forth motion. In this way, cam wheel 296 also guides bearing housing 90 over cam follower 288 back and forth.
