the strand is now gripped by the gripping element of the second spindle and in the temporary winding area of the second spindle is wound up. The strand between the two spindles is severed or torn; finally the strand to be wound is then along the second Spindle returned from the temporary winding area to the main winding area at the beginning of a new pack build-up.

The invention can also be used in a winding device with only one rotationally driven spindle with main winding area and temporary winding area for the strand material to be wound up. The spindle also has a fixed one in its temporary winding area Gripping element, which is effective in such a way that the through this area guided strand is finally grasped by the gripping element. In addition, an intermediate peeling system is provided, which then pulls the strand out further when it is not wound onto the spindle; the intermediate peeling system is in spaced relation to the spindle on one arranged in such a position that the strand is guided along a path that connects it with the spindle in its temporary Brings winding area into contact, so that the gripping element also arranged on this spindle, the strand during the spindles ! can detect rotational movement and cause the strand to be wound onto this spindle. At the same time it comes to one Separation of the strand material between the spindle, which now continues the winding process, and the intermediate draw-off system. In addition, it is then still necessary to use the strand material to build the pack from the temporary winding area in which

The winding device includes a rotatable and corresponding an indexing changeable head or turret 40 in front of the housing 39; the head has two hollow projecting portions 41 which include bearings, in which the rotatably mounted spindles or winding heads 42 and 43 are mounted for the winding process. The head 40 is in turn supported by arrangements within the housing 39. Each spindle 42 and 43 is driven by a motor 44, one of which is shown in FIG. The motors 44 are also supported by the head or turret 40, which can be moved in two indexable positions. The spindle 43 is in its winding and assembly position in FIG. 2 shown for a winding package, while the spindle 42 is arranged diametrically opposite in a standby position »

The head 40 is designed to switch in two positions can be so that the spindle with a fully built package out of the winding position and a empty spindle can be moved to the winding position for building a new pack. The head 40 is powered by a motor 46 rotated via a reduction gear which is arranged within a housing 48; as further suitable drive elements a belt 50 and two sprockets or pulleys 51 and 52 are provided. The excitation of the drive motor 46 the head rotation is controlled by suitable indexing systems of conventional construction and timed so that that the head 40 is rotated at the winding position when building a complete strand package.

Each spindle 42 and 43 is designed so that it Strangwik-

Ke! arrangements, for example a tubular sleeve 54 on which the package is wound. The for
The motors 44 responsible for the rotation of the spindles and the winding tubes are designed so that their speed can be progressively reduced in order to increase the rotational speed of the
Reduce the spindle at the winding position when the strand packs are continuously built up during the winding process.

The initial area of each spindle 42 and 43 is provided with the usual provided in the longitudinal direction extending recesses in which rods or friction shoes, not shown, are arranged are, which are biased in an elastic manner radially outward, so that the tubular sleeves pushed on or collectors are detected with frictional engagement and ensured is that they perform a rotary motion together with the spindles.

A separating arrangement 60 is fixedly arranged on the head 40 between the spindles 42 and 43. The partition wall 60 separates the respective Winding areas of the spindles.

Furthermore, the winding device has a traversing or transverse guide arrangement 61, which distributes the strands in the longitudinal direction over the pack and gives the strands an oscillating movement while sliding back and forth over the pack, thus creating a crossing effect of individual turns of the
Strands as they build up to reach the packs. at
the illustrated embodiment is one of the strands
an oscillating motion imparting assembly 62 carried by a reciprocating shaft 63 extending therefrom

extends from the housing 39.

The strand guide part 62 causing the oscillating strand movement is fixedly arranged on the shaft 63 and driven at a variable speed, for which purpose an electric motor is used. In
Usually an empty tube is pushed onto the spindle to wind up the strands; as the strand is operating at relatively high linear velocities up to about 4580 meters per
Is wound back and forth, the oscillating strand distributor 62 is also set in rotation at comparatively high speeds in order to bring about the high-frequency oscillating movement of the strand to cause individual turns of the strand to cross over on the spindle.

The winding head or spindle illustrated in Figures 1-3 can be described as having a package build area for the reel spool and a temporary winding area. The pack build-up area is the part of the
Spindle on which the strand is wound up to form a package 55. The spindle's temporary winding area is in
1, 2 and 3 shown as an end cap assembly 56. The end cap assembly 56 has a guide surface, a
Groove or recess 58 which extends circumferentially around the spindle end in the temporary winding area, as well
via a pin or a gripping element 57 which protrudes into the groove. The end cap assembly 56 will be discussed further below
explained in more detail.

In Figs. 1 and 2 there is an ejector, ejector, or lead-away arrangement shown in their retracted position. This repulsion of order, as it is merely referred to in the following

comprises a rod 66 which is held in the housing 39 in a bearing. The repulsion process can be activated by activating an actuating arrangement 68 are effected, which in the illustrated embodiment is designed as an air cylinder is. The repelling can of course also be carried out by other conventional means.

In Fig. 3, the push-off assembly is in its extended position shown. As shown, in this position it has an L-shaped Projection 67, which starts from the rod 66 and is directed forward, touches the strand 30 and moves it into the end region the spindle 42 is transferred. This means that the strand 30 from its normal direction of travel 31, in which the strand automatically based on the generated during strand winding Voltage is moved, has been led out, namely by means of the push-off arrangement to be explained in more detail below. The strand 30 then usually runs vertically downward from the projection 67 of the push-off arrangement to the end cap arrangement 56 or to the end of the spindle. The strand enters the grooved area 58 of the spindle end portion and becomes detected there by the pin or the gripping element 57. This spindle end region 56 is also explained in more detail below. The push-off arrangement serves a dual purpose. Thus, the push-off arrangement can be used to pull the strand 30 off to keep out of its natural running position 31 in the package build-up area, the strand then in the temporary winding area 56 is further wound up. The repulsion arrangement can also be used to pull the strand out of its natural Then push out running position 31 in the pack build-up area, when a wrap has been completed.

So far, a simple push rod 66 and an L-shaped projection 67 extending therefrom have been used as a push-off arrangement has been described. This mechanism can also have a different structure. For example, FIG. 13 shows a push-off arrangement detailed and complicated structure shown, which is explained in more detail below. Fig. 1, Figures 2 and 3 show a winder which builds a single package on a spindle; however, this is only as by way of example, because the invention also extends to the construction of two or more winding packs on one Spindle. For example, FIG. 13 shows the winding of two winding packages on a spindle.

Figures 4, 5 and 6 show the automatic handover process of the strand from one spindle to another in a winding device, which in the embodiment of the winding device 1, 2 and 3 corresponds. First, the strand 30 moves along its normal strand travel line 31 and is driven by the oscillating traverse guide assembly 61 in the package build area the spindle 43 wound up. Then, once the package has been finished wrapping, the pusher assembly becomes activated and the push rod 66 is moved forward bringing the cord 30 into contact with the projection 67. It moves then the repelling assembly moves the strand from the package build area of the spindle to the temporary winding area or End cap area of the spindle 43.

In Fig. 4 it is shown that two spindles 42 and 43 are mounted on the head 40. There is one between the spindles central plate or a partition wall 60. The partition wall 60 extends from the head 40 starting so that it the two packs

kung construction areas of the spindles separates from each other, it ends but before the respective temporary winding areas. Each spindle has or in its temporary winding area End cap section, as already mentioned, via a circumferential guide surface or groove 58 and via a solid, stationary one Gripping element or pin 57 which extends into the groove. The groove 58 and the gripping element 57 are shown in FIG. 7 8 and 8 and will be explained in detail with reference to these figures. Fig. 4 shows the spindle 43 in the Winding position, with the package wound on it has been completed or fully wound.

Fig. 5 shows the push-off arrangement in the extended position, the strand 30 laterally along the spindle to the iBitweiligen Winding area of the spindle 43 has been moved. As a result a corresponding head rotation, the strand 30 running to the first spindle is replaced by the second, rotating one Contacted spindle 42 in its temporary winding area so that strand 30 is gripped by gripping element 57 and carried along is, so that now the strand is wound up in the temporary winding area of the second spindle 42 and that Material between the two spindles 42 and 43 experiences a separation. As shown in the figures, the turret moves 40 moves the fully assembled package 55 on the spindle 43 from the winding position and moves the second rotating one Spindle 42 into the winding position. The strand 30 runs, as shown, in the circumferential groove 58 of the second Spindle 42 and is gripped by its gripping element 57.

In the illustration of FIG. 6, the index-wise rotary movement of the rotary head 40 is completed. It is now the

- 16 -

Λ 41 787 in
a - 168

Spindle 42 in the winding position; as shown is the strand 30 from the pin or gripping element 57 of the second spindle 42 been captured or captured. The strand is guided under the pin and, when the spindle 42 is rotated further, has the strand is bent over the gripping element 57. In this way, the gripping element 57 succeeds in grasping the strand or to capture and to lead with the rotary movement of the spindle, so that the winding of the strand in the temporary The winding area of the spindle 42 begins. At the same time, the Strand between the spindles 42 and 43 separated. As can be seen from the drawings, the spindle 42 pulls itself part of the strand located between the two spindles in a clockwise direction when winding the strand in the temporary Winding area of the second spindle 42. At the same time, the first spindle 43 keeps the strand either stationary or moving the part between the spindles also clockwise, so that it can be determined that the strand between the spindles is pulled in opposite directions and thus torn which causes a separation of the strand between the spindles. The completed pack 55 is then built up by the stationary spindle 43 withdrawn and replaced.

Now the strand or the linear material to be wound up becomes wound on the temporary winding area of the spindle 42 with the normal running line of the strand 30 in Direction of the pack build-up area or the normal winding, treatment area of the spindle 42 runs. Therefore, if the push-off assembly is not deployed, the cord will move automatically laterally along the second spindle from the temporary winding area towards the normal main winding area and begins to build the pack. However, at

- 17 -

a preferred embodiment proceeded so that the The push-off arrangement or the push rod remains in its extended position until the spindle is at its desired position Rotation speed has been brought. Then the push-off assembly is retracted and the strand moves along the Spindle to the package build-up area.

7 and 8 show an enlarged representation of the temporary Winding area, as it has already been mentioned with reference to FIGS. 1-6. This temporary winding area or end cap part consists of the already mentioned groove or guide surface 58 and a pin or gripping element 57. The guide surface 58 can, for example, be a long, narrow groove or a channel that extends around the circumference the spindle extends. The pin can extend in or above the groove or guide surface 58. For example, can the pin or the gripping element 57 can be mounted on a shoulder or an edge of the spindle, the guide surface the circumferential end region of the spindle can be without a groove.

As shown in the figures, the spindle at its temporary Winding area over a circumferential surface part and a gripping element, which is at least partially in the axial direction to the spindle and at an outward distance from the circumferential surface part of the Spindle extends. The end of the gripping element forms a opening in a space between itself and the peripheral surface part, so that during the rotational movement of the spindle in front of the actual pack structure of the along one of the Axis of rotation of the spindle crossing path extending strand

- 18 -

609882/1069

Λ 41 787 m

laterally this path can be moved in an axial direction to the spindle along the surface part. The strand moves through the just mentioned opening in the space between the surface part and the outwardly extending one Grasping limb and is caught by it, so that it is now moved with this and the temporary winding process of the strand begins in this temporary winding area.

As the illustration of FIG. 7 can be seen, the element 57 consists of a stationary, fixed pin, which extends into the groove 58. The strand 30 moves along the guide surface or groove 58 in a position below of the fixed straight gripping element 57. The representation 8 shows the strand in its position below the gripping element 57, in which the strand is removed from the element 57 has been detected. The strand is held in place under the pin or gripping element in the manner of a wedge effect. During the further rotational movement of the spindle, the strand is rotated or bent over the gripping element 57, so that it is detected and the strand is entrained and thus wound up in the temporary winding area. In the illustration of FIGS. 7 and 8, the gripping element 57 is as elongated, straight cone shown. It goes without saying, however, that this is also a curved rod or a Hook can act. The gripping element can also extend over the guide surface at an acute angle or at another Extend angle so that the strand wedged between the guide surface and the gripping element as it moves further and is held, namely below the fixed gripping element.

In the figures, the temporary winding area is shown as that it is at the free end of the spindle. However, it is also within the scope of the invention to arrange the temporary winding area at a different location on the spindle, for example near the other end of the spindle. The temporary winding area could also be attached a central part of the spindle, which means that more than one package is wound on the spindle. It is also possible for more than one temporary package to be installed on a spindle on which more than one package is built Winding area can be present. For example, if there are two normal main winding areas on a spindle, then there can be a first temporary winding area in the central part of the spindle and a second temporary winding area located on one of the end parts of the spindle.

The illustration in FIG. 10 shows a further exemplary embodiment of a temporary winding area. This End cap or temporary winding area 80 fulfills the functions already mentioned above, with the element 84 the strand which has been guided by the guide surface 82 below it, detected when the strand at the beginning of the winding process is wound onto the temporary winding area. In the embodiment of FIG. 10, this forms Gripping element 84 and the guide surface or groove 82 of the end cap area or temporary winding area is a one-piece whole and can also be produced in this form, Such a one-piece construction can be attached to the spindle in the temporary winding area after it has been formed or on the peripheral surface of the spindle in this area be postponed.

11 and 12 show side views of further exemplary embodiments of spindles with their temporary winding areas. In the illustration of Fig. 11 is a grooved guide surface, as already stated above, shown, which has two gripping elements 87. As mentioned, it can These gripping elements 87 are fixed stationary ones Act pegs that extend into slot 88 in temporary winding area 86. The stationary cone-like Gripping elements 57 are offset from one another by 180 °. In the illustration of FIG. 12 there are three, those already mentioned above Gripping elements similar gripping elements 91 shown, which extend into a groove 92 of the temporary winding area 90. The stationary pins 91 are evenly around the Spindle distributed, so that a total of more than only one gripping element can be used, which then on different Positions around the spindle can be distributed.

9 shows, in the form of a diagram, the time sequence of the approximate spindle speed in the case of the spindles movements to be carried out according to Figs. 1-6. The speed of the first spindle is shown in solid lines indicated, while the speed of the second spindle is shown in dashed lines.

From point A to point C, the first spindle accelerates yours Rotation speed in order to achieve the desired spindle rotation speed X at the beginning of the package build-up. After reaching the desired speed X at time C, the strand is oscillated back and forth, and the package is built up in the main winding area of the first spindle. When the pack builds up, during the winding

- 21 -

809882/1069

A 41 787 πι

June 1976 - 21 -

time the spindle speed is reduced in the usual way from the speed X to the speed Y, where this speed change, as shown in FIG. 9, can take place linearly or non-linearly. The package structure is then completed when the speed of rotation of the spindle has reached the value Y. The winding time for the first spindle is the same hence the distance between positions C and E of the diagram of FIG. 9. As soon as the first pack approaches its completion, the second spindle is set in rotation; this rotary motion starts at time D, with the second spindle then at time F to the desired initial winding speed X has been brought.

The handover or rotation of the turret or turret takes place at time E, at which the two curves of the spindle speeds intersect. At this time the assembly of the first package is complete and the push-off assembly has the strand to the temporary winding area the first spindle moved. The turret is indexed and the strand becomes with the temporary winding area The second. Spindle brought into contact. When the temporary winding area of the second spindle comes into contact the strand is grasped or caught by the gripping element in this winding area, and winding begins of the strand on the second spindle. The rotary head is therefore rotated around the second spindle in place of the package on the structure and remove the first spindle from the winding position. The strand between these two spindles is As already explained above, torn or separated, and the strand is now wound onto the temporary winding area of the second spindle.

- 22 -

609 882/1089

A 41 787 m

This is how the strand is passed from one spindle to the other in the time frame of point E of the curve of FIG. 9; the first spindle is then by means of a brake stopped in the period between points E and G. After the first spindle has stopped, the pack is pulled off and exchanged. The first spindle is then made ready for winding the next pack. During the period between the points E and F of FIG. 9, the second spindle is raised to the winding speed, wherein the push-off assembly, which keeps the strand away from the main winding area, is still extended, so that the strand during this Period of time is wound on the temporary winding area of the second spindle. At time F, the second spindle has reaches its desired initial winding speed X which is suitable for the package construction. The bumper pulls back and the strand moves sideways over the spindle to the package build area. This is where the strand then guided back and forth in an oscillating manner and wound up in this main winding area to form a package, the one just described cycle starts from the beginning.

Another exemplary embodiment is shown in the illustration in FIG. 13 of the present invention.

on the spindle takes place in the form of two packs 94.

As stated, this double-packing spindle forms a further embodiment of a spindle which can be used in conjunction with the winding device described in FIG. 1 can be used. The double packing spindle can be on a Rotary head are located, together with a second double packing spindle, as already described above.

At the end of the twin pack spindle is a temporary winding area 98 similar to those previously described Winding areas with a circumferential guide surface or a recess 104 and a solid, stationary pin 106. When the push-off assembly is in its extended position, as shown in Fig. 13, then the strands 102 are engaged by this element and are in the temporary winding area wound up. When withdrawing After the bumper, the strands move up sideways across the spindle into their separate main package build-up areas the spindle. When the pack is fully assembled, the bumper extends again and moves both strands into the area 98 temporary winding. The push-off arrangement is shown in FIG. 1 and is explained in more detail below.

When the push-off assembly extends, it contacts the first strand with its guide surface 114. The strand moves along the guide surface and is removed from its oscillating transverse guide arrangement when it is in the recess or moved paragraph 115. If the push-off arrangement is extended further, it also touches the second strand their guide surface 114. This strand also moves longitudinally

the guide surface and is supported by its transverse guide arrangement lifted off and moved into recess 115. The first strand is guided in such a way that he does not depend on the second oscillating transverse guide arrangement or oscillating arrangement, as they do hereinafter referred to, can be detected when it moves to the temporary winding area. With a further one When the push-off arrangement is extended, both strands move to the recess 115 and, as they continue to move, become the Temporary winding area combined into a single bundle 102a to finally in this temporary winding area To be caught and wound up. The string transfer (to the other spindle) then continues as before already described above.

The repelling arrangement 108 is shown in Fig. 13 and in Fig. 14 so that the actual push-off system 112 is fastened to a bearing arm 110 with the aid of fastening means 111. The fastening means 111 can be screws, which is guided through a slot 113 in the push-off system 112 are.

Package builds up and picks up the strands from the rocker assemblies and moves them into recess area 115. Guide surface 114 is shown sloping towards the path of travel extends the repulsion assembly. In Fig. 13, guide surface 114 is shown to contact both strands and introduces them together into recess 115 as push-off system 112 moves toward the temporary winding area the spindle moves. The longitudinal slot 113, which is used to attach the push-off system 112 to the support arm 110, enables the adjustable arrangement and the orientation of the push-off system such that during the movement of the push-off assembly the guide surface 114 can grip the strands.

Adjacent to the recess 115 is a slot with open end portion or notch 116. The recess and the open ended slot 116 are in open communication with each other, so that the strand, which moves along the guide surface 114 to the recess 115, during the transfer of the Strand is moved from one spindle to the other, as already described above, into the slot 116. During the transfer of the rotary head of the strand from one spindle to the other, the new overall strand 102a moves out of the recess 115 into the open slot 116. Open slot 116 is like that effective in that the strand is held in the push-off position during the temporary winding area of the one Spindle is transferred to the temporary winding area of the other spindle. After the handover, the strand moves in the recess 115, which has the tendency and offers the possibility of the strand from the temporary winding area in retract the package build area when the push-off assembly is withdrawn in total.

As shown in FIG. 14, the guide surface 114 extends in an obtuse or oblique angle to the path of movement of the push-off system 112 and has a positive inclination. On The recess 115 is located at one end of the guide surface 114. This recess is arranged at an acute angle with respect to the movement path of the push-off system and has a negative slope or slope. The recess can be cut as a small guide surface (relative to the guide surface 114) being. It is also possible that the guide surface 114 with ends at a radius (for example 0.16 cm) and that this curved surface forms the recess 115.

The push-off system 112 remains in its extended position, so that the strand moves vertically downwards from the push-off system to the temporary winding area in this Can move spindle position. The push-off system remains in its extended position as long as it is being wound up of the strand on the temporary winding area is desired. The winding of the strand in this temporary winding area may be desired until the spindle reaches the speed required for package build-up has. If the strand is then to be moved from the temporary winding area to the main packing area, then it pulls the push-off system back. When the push-off system returns, the strands collect in the recess, depression or Bulge 115. The recess 115 tends to hold the strands in place during the push-off system runs back, so that there is a tendency to move the strands from the temporary winding area in the direction of the package build-up area to pull the spindle. When the push-off assembly retreats past the normal strand course line 100,

the strand tension removes the strand or strands from the recess 115 and the strands are removed from the respective Detected vibratory arrangements for the pack structure. This is how the Return of the repelling arrangement initially repelled one of the strands and gripped by its swing assembly for winding into a package; then the second strand leaves the push-off arrangement at its associated winding area. If the push-off system 112 is fully retracted, then there is this is no longer in contact with the strand or strands, and the strands become the structure in the usual oscillating form a pack guided back and forth.

Another embodiment is shown in FIGS. 15 and 16 Invention shown. Again, this is a process for forming continuous glass filaments from in Heat softening glass material, whereby the glass thread becomes one Strand combined and then, as shown, wound up to form a winding package.

The illustration of Figure 15 includes a container or feeder 120 containing a supply of molten glass. The container 120 can be connected to a forehearth (not shown) feeding molten glass from a melting furnace to the container; it is also possible that the container 120 in Form, not shown, glass, for example glass spheres, and fed in a melting device assigned to the feeder 120 be brought into a molten state. The feeder 120 is similar to the feeder or nozzle of FIG. 1. The glass threads 121 drawn from this are coated with a sizing material in the area of an application arrangement 122 and from a strand guide 124 to a strand

in summary. The applicator system for the size is similar that in Fig. 1; further parts of the winding device, as shown in FIGS. 15 and 16, correspond to the system of US Pat. No. 3,539,317 and are therefore not discussed in any further detail below.

If the strand is not wound up, then the strand can be drawn off from a pulling roller system 144. This pulling roller system is described in the just mentioned US patent. The pulling roller system is a temporary, strand-pulling system or "an intermediate assembly that sends strand 126 to waste via a waste chute 148 Waste collection area supplies. The strand is here between the operatively connected, moving ones Surfaces introduced by rollers that rotate together and pull the strand downward.

In order to build a new pack, the strand 126 is fed into the peel system 146. This peeling system 146 is arranged below the spindle 154 at such a point, that when the strand is withdrawn by the withdrawal system, the spindle 154 and the temporary winding area touched on the spindle. The position can be such that the strand is wrapped around the spindle in the temporary winding area or is bent around it. The peel system, as shown, is similar to peel system 144. It may be this involves a pneumatic pull-off system, pulling rollers or other common strand-pulling systems. The strand will from the stripping system 146 through the waste chute 148 to the waste collection area fed. As the strand is fed into the withdrawal system 146, as shown in FIG.

shows the push-off system is in its extended position. Thus, the strand 126 from the peeling system 146 becomes vertical from the kicking system and over the temporary winding area the coil 140 is withdrawn. It is within the scope of the present invention Framework that the withdrawal system also comprises a winding arrangement to wind up the withdrawn strand as waste.

The temporary winding area of the spindle 154 is designed similarly to that already described above. He disposes via a surface or recess or groove 150 and a stationary gripping member 152. The strand passing through or over the temporary winding area is withdrawn, touches the spindle in this area and is thus in engagement with the stationary gripping element 152 brought. In other words means that is, the withdrawal system 146 withdraws the strand 126 at start-up during the times that the strand is not wound on the spindle 154. The intermediate withdrawal system 146 is in spaced relationship with the spindle located in a position effective to withdraw strand 126 along a path which brings it into contact with the bobbin in its temporary winding area, so that the stationary gripping element 152 can grasp the strand during the rotational movement of the spindle so as to begin winding the strand on the spindle and to separate the strand between the spindle and the extraction system. As already explained above, the strand is then once it has been gripped by the gripping element, by the temporary winding area in one direction and moved by the peeling system 146 in the other direction, causing it to rupture of the strand and severing of the strand connection between the spindle and the withdrawal system.

Has the winding of the strand once in the temporary winding area started, then the push-off arrangement can hold the strand for winding in the temporary winding area as long as until the spindle has reached its desired speed of rotation. The push-off system is then required after reaching the required Initial winding speed of the spindle retracted. When the push-off system is drawn in, the strand moves laterally to the main pack winding area for the pack build-up.

In the illustration of FIGS. 15 and 16, only one winding area for a pack is shown, but it is located within the scope of the invention that the spindle has more than one packing assembly area. For example For example, the spindle can be designed similarly to the spindle of FIG temporary strand winding area are provided. The temporary strand winding area is at the free end of the spindle shown, but it is within the scope of the invention Frame to arrange this on the side of the spindle facing the housing. If the spindle has two packing structure areas, then two temporary winding areas can also be provided, one at the end of the spindle and the other are in a central part or at the other end of the spindle.
