Description

WINDING DEVICE

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding apparatus for obtaining a winding body by winding a belt-like sheet.

The winding body to which the belt-like sheet is wound may be formed in a flat shape.

In the flat-shaped winding body, the radius of curvature of the curved portion located at both ends in the major axis direction thereof becomes very small. Therefore, depending on the thickness or hardness of the sheet to be wound, there is a fear that the sheet is damaged by a bending stress applied to the curved portion.

On the other hand, in regard to a sheet having a predetermined lamination portion formed on the surface of the sheet, a lamination portion is formed intermittently in advance along the sheet long direction in advance, and a non-lamination portion portion in which the lamination portion is not formed (For example, refer to Patent Document 1).

Here, in the curved portion of the winding body in which the sheet is wound several times, the sheet length becomes longer as the outer side is. Therefore, in the case where the laminated portion is intermittently formed on the sheet as described above, the interval (the length of the non-laminated portion in the sheet longitudinal direction) between the two laminated portions adjacent to each other in the sheet longitudinal direction is set to the starting end (The position in the sheet longitudinal direction end portion) of the plurality of laminated portions is set to be gradually longer from the side of the winding end to the end of the winding end ).

[Patent Document 1] Japanese Unexamined Patent Application Publication No. 10-270068

However, even if the interval between the lamination portions is set to a predetermined length as described above, due to a variation in the thickness of each lamination portion, a molding error in the interval between the lamination portions, and a change in tension applied to the sheet during winding, As the sheet is wound, there is a possibility that the positional relationship between the plurality of laminated portions may be deviated. As a result, the quality of the wound body may deteriorate.

The winding device according to any one of the means 1 to 6, characterized in that each time the sheet is wound a predetermined length, the sheet wound on the core is recessed toward the recess.

(1) According to the above-mentioned means (1), the length of each non-stacked portion on the sheet is set to a dimension having a margin beforehand, and each time the sheet is wound a predetermined length, The sheet is wound while aligning the end position of the sheet in the sheet longitudinal direction with the reference position by the position adjusting means. As a result, the positions of the plurality of laminated portions can be precisely aligned without being affected by manufacturing errors of the laminated portions on the sheet. As a result, it is possible to improve the quality of the winding arranged so that a plurality of stacked portions are stacked.

(2) According to the means 2, the same effect as that of the means 1 can be obtained.

(3) In a configuration in which the first reference position and the second reference position of the means 3 are not provided at intervals of 180 [deg.], For example, when the first reference position and the second reference position are spaced apart by 90 [deg. The positioning of the second sheet must be performed at different timings. As a result, there is a fear that the number of times of stopping the stopping is increased and the productivity is lowered.

On the other hand, according to the means 3 described above, the positioning of the first sheet and the positioning of the second sheet can be performed simultaneously (during one stop). As a result, it is possible to reduce the number of times of stopping the winding for positioning of the sheet, thereby improving the speed of the winding device and the productivity.

(4) According to the above-mentioned means 4, after the sheet in the aligned state is pressed by the second pressing means, the winding by the winding can be immediately resumed. As a result, for example, the sheet wound on the sheet pressed by the first pressing means is pressed by the second pressing means, and then the sheet is pressed again by the first pressing means, It is possible to shorten the time for stopping the winding of the sheet for aligning the sheet or the like as compared with a configuration in which the second pressing means is moved apart and then the winding is driven. As a result, it is possible to increase the speed of the winding device and further improve the productivity.

Here, for example, a pair of claw members (pressing members) are provided at two different positions in the rotation direction of the crown, and the function of the first pressing means and the second pressing means in the pair of toe members Or alternatively may be alternatively configured. According to this configuration, first, for example, the sheet wound on the sheet pressed by the first toe member is pressed by the second toe member. Subsequently, in this state, the winding is rotated and the pressing by the first toe member is released. After the sheet is wound a predetermined length, the sheet is wound on the sheet pressed by the second toe member and pressed by the first toe member. Thereafter, this operation is repeatedly performed. Thereby, the sheet can be wound while pressing the sheet alternately with a pair of toenails.

(5) If the sheet is pressed in a curved portion of the crimping, there is a fear that the sheet (end position in the sheet longitudinal direction of the lamination portion) is displaced. On the other hand, according to the means 5, the sheet can be stably pressed.

Here, for example, in the configuration related to the above-mentioned means 2, it is preferable that the winding core has a pair of arc-shaped surfaces sandwiching the rotation axis therebetween and mutually facing each other with the rotation axis therebetween May have a substantially elliptical cross-section. According to such a configuration, in manufacturing the same winding body, the turning radius of the winding core can be made smaller, as compared with the case of winding the sheet by using, for example, a flat- The flapping of the winding device can be suppressed, and the winding device can be made compact.

(6) In the configuration in which the position of the end portion in the sheet longitudinal direction of the laminated portion on the sheet is aligned in the curved portion of the winding core, for example, in the pressing step such as pressing the winding body in a flat shape after completion of winding, There is a possibility of causing positional deviation. On the other hand, according to the means 6 described above, it is possible to suppress the occurrence of such a problem and to align the end positions of the laminated portions in the sheet longitudinal direction with higher accuracy.

(7) In the configuration in which the recess is not provided on the core and the sheet is wound so as to be convex toward the outer side of the core, when the lamination portion is aligned, the outer sheet to be aligned is interfered with the already- There is a possibility that alignment can not be performed appropriately and smoothly. For example, there is a fear that a large load is applied to the position adjusting means due to friction between the inner sheet and the outer sheet. In addition, in the case where the sheet length of the inner sheet is longer than that of the outer sheet due to manufacturing errors or the like, and the outer sheet is wound tightly (bulky), if the outer sheet is not taken up more tightly, The position does not reach the reference position, and there is a possibility that the alignment can not be performed.

On the other hand, according to the above-mentioned means 7, since the inner sheet is wound around the core in the recessed portion at the portion provided with the recess, the contact area with the sheet wound on the outer side is reduced, Can be suppressed. As a result, the positioning operation of the sheet can be facilitated, and the positioning accuracy can be improved. Further, the quality of the winding can be improved.

The middle plate 95 is provided so as to be movable from an insertion position where it is inserted between the press plates 91 and 92 to a retreat position where it is retracted from between the press plates 91 and 92.

Next, the winding procedure of the winding body 1 using the winding apparatus 10 will be described in detail. Fig. 3 shows a state in which the winding process for one time is completed. In this state, both edge portions in the sheet width direction of the vicinity of the leading ends of the first sheet aggregates 2, 4 fed from the nip rollers 71A, 71B are connected to the pair of first conveying chucks 14A, As shown in Fig. Likewise, both edge portions in the sheet width direction of the vicinity of the leading ends of the second sheet aggregates 3, 5 fed from the nip rollers 81A, 81B are separated by the pair of second conveying chucks 15A, 15B in the initial position And is in a gripped state. The core 13 is stopped in an initial state in which a pair of flat portions 13c are arranged along the vertical direction.

In this state, when the winding process of the new winding 1 is started, the first conveying chute 14A, 14B and the second conveying chute 15A, 15B are driven by the first sheet aggregate 2, And moves toward the core 13 in a state in which the two sheet assemblies 3, 5 are grasped.

In this state, the nip rollers 71A and 71B and the nip rollers 81A and 81B are closed. The first sheet 4 and the separating sheet 2 supplied from the sheet feeding mechanisms 31 and 51 are superimposed by the nip rollers 71A and 71B to form the first sheet aggregate 2, 4) and is drawn out to the core 13 side. Similarly, the second sheet 5 and the separating sheet 3 supplied from the sheet feeding mechanisms 41 and 61 are overlapped by the nip rollers 81A and 81B, and the second sheet aggregates 3 and 5 are stacked, And is drawn out to the core 13 side.

When the leading end portions of the first sheet aggregates 2 and 4 reach the flat surface portion 13c of the core 13, the first sensor 18 winds the laminated portion 4a on the first sheet 4 The detection of the starting end 4c is performed. On the basis of the detection result of the first sensor 18, at the position where the winding start end side end portion 4c of the laminated portion 4a on the first sheet 4 reaches the first reference position K1, (14A, 14B). At the same time, the pair of first pressing claws 20A press the both edge portions of the first sheet aggregate 2, 4 in the sheet width direction to fix the first sheet aggregate 2, 4 to the winding core 13 (See FIG. 5).

Likewise, when the leading end portions of the second sheet aggregates 3 and 5 reach the flat surface portion 13c of the core 13, the second sensor 19 detects the stacked portion 5a on the second sheet 5, The end 5c of the winding starting end side of the winding is detected. Then, on the basis of the detection result of the second sensor 19, at the position where the winding start end side end portion 5c of the lamination portion 5a on the second sheet 5 reaches the second reference position K2, (15A, 15B). At the same time, the pair of first pressing claws 20A press the both end edge portions of the second sheet aggregates 3, 5 in the sheet width direction and fix the second sheet aggregates 3, 5 to the core 13 (See FIG. 5).

When the first sheet aggregates 2 and 4 and the second sheet aggregates 3 and 5 are fixed as described above, the nip rollers 71A and 71B and the nip rollers 81A and 81B are opened, 13) is rotated in the counterclockwise direction (counterclockwise counterclockwise direction) of FIG. 5 to start winding. In synchronism with this, the first conveying chucks 14A and 14B and the second conveying chucks 15A and 15B respectively hold the first sheet aggregates 2 and 4 and the second sheet aggregates 3 and 5 And moves toward the core (13).

When the core 13 is rotated 180 degrees from the initial state and the first and second sheet aggregates 2 and 4 and the second sheet aggregates 3 and 5 are wound by a predetermined length, The first conveying chucks 14A and 14B and the second conveying chucks 15A and 15B, which move, stop once. Here, in the core 13, a pair of flat portions 13c are arranged along the vertical direction, similarly to the initial state before the start of winding.

In this state, as described above, since the lengths of the non-stacking portions 4b, 5b between the respective stacking portions 4a, 4a and the stacking portions 5a, 5a are set beforehand with margin, The end 7c of the lamination portion 4a on the first sheet 4 does not reach the first reference position K1 and the end 7c of the lamination portion 5a on the second sheet 5 does not reach the first reference position K1, ) Does not reach the second reference position K2 (see Fig. 6).

The first conveying chuck 14A and 14B holding the first sheet aggregate 2 and 4 are moved to the core 13 and the first sheet 18 is conveyed by the first sensor 18 The end portion 4c of the lamination portion 4a on the winding starting end side is detected. On the basis of the detection result of the first sensor 18, at the position where the winding start end side end portion 4c of the laminated portion 4a on the first sheet 4 reaches the first reference position K1, (14A, 14B). Simultaneously, both edge portions of the first sheet aggregate 2, 4 in the sheet width direction are pressed by the pair of second pressing claws 20B (see Fig. 7). At this stage, the first sheet aggregates 2, 4 are pressed by the pair of first pressing claws 20A and the pair of second pressing claws 20B.

Similarly, when the end 5c of the lamination portion 5a on the second sheet 5 does not reach the second reference position K2 and the end portion 5c of the second sheet aggregate 3, 2 transfer chucks 15A and 15B toward the winding core 13 and the second sensor 19 detects the winding start end 5c of the laminated portion 5a on the second sheet 5 . Then, on the basis of the detection result of the second sensor 19, at the position where the winding start end side end portion 5c of the lamination portion 5a on the second sheet 5 reaches the second reference position K2, (15A, 15B). At the same time, both side edge portions of the second sheet aggregates 3, 5 in the sheet width direction are pressed by the pair of second pressing claws 20B (see Fig. 7). At this stage, the second sheet aggregates 3, 5 are pressed by both of the pair of first pressing claws 20A and the pair of second pressing claws 20B.

When the first sheet aggregates 2 and 4 and the second sheet aggregates 3 and 5 are positioned and fixed, the first conveying chucks 14A and 14B and the second conveying chucks 15A and 15B, The aggregates 2, 4 and the second sheet aggregates 3, 5 are opened and returned to their initial positions. The first conveying chucks 14A and 14B hold the opposite edge portions in the sheet width direction of the first sheet aggregates 2 and 4 and the second conveying chucks 15A and 15B hold the second sheet aggregates 3 and 5 in the sheet width direction.

Thereafter, the core 13 is rotated and the winding is restarted. The first conveying chucks 14A and 14B and the second conveying chucks 15A and 15B convey the first sheet aggregates 2 and 4 and the second sheet aggregates 3 and 5 To the core (13). Here, the first pressing claw 20A, which has pressed the first sheet aggregate 2, 4 or the second sheet aggregate 3, 5, is separated from each flat surface portion 13c of the core 13, The sheet assemblies 2 and 4 and the second sheet assemblies 3 and 5 are pressed only by the second pressing claw 20B.

Thereafter, as the first sheet aggregate 2, 4 and the second sheet aggregate 3, 5 are alternately pressed by the first pressing claw 20A and the second pressing claw 20B, The first sheet aggregate 2, 4 and the second sheet aggregates 3, 5 are wound around the core 13 by being repeatedly performed.

Here, only the pressing operation of the first sheet aggregate 2, 4 and the second sheet aggregate 3, 5 by the first pressing claw 20A and the second pressing claw 20B will be described with reference to the operation thereof . The first sheet stack 2 or 4 or the second sheet stack 3 or 5 pressed by the first pressing claw 20A and wound on the second sheet stack 3 , 5) or the first sheet aggregate (2, 4) is pressed by the second press claw 20B. Subsequently, with this state, the core 13 is rotated and the pushing by the first pressing claw 20A is released. Then, the core 13 is rotated by 180 占 and the first sheet aggregate 2, 4 or the second sheet aggregates 3, 5 are wound a predetermined length, and then the second sheet claw 2, The first sheet aggregate 2, 4 or the second sheet aggregate 3, 5 wound on the sheet aggregates 3, 5 or the first sheet aggregates 2, And is pushed by the claw 20A. By repeatedly performing the above operation, the first sheet set 2, 4 and the second sheet set 3, 5 are alternately pressed by the first pressing claw 20A and the second pressing claw 20B The first sheet aggregate 2, 4 and the second sheet aggregate 3, 5 can be wound around the first sheet aggregate 2,

Then, the core 13 is once stopped by the core 13 when the winding of one winding 1 is almost completed. Subsequently, the pair of feeding rollers 33A and 33B are closed, and after the first sheet 4 is gripped, the first sheet cutting cutter 34 cuts the sheet. Similarly, the pair of feeding rollers 43A and 43B are closed, and after the second sheet 5 is gripped, the second sheet cutting cutter 44 cuts the sheet.

When the cutting of the first sheet 4 and the second sheet 5 is completed, the core 13 is rotated by a predetermined amount and the ends of the first sheet aggregates 2, 4 and the second sheet aggregates 3, (The remaining portion of the wind).

When the winding of the end portions of the first sheet 4 and the second sheet 5 is completed, the first conveying chute 14A, 14B and the second conveying chute 15A, 15B are opened and the separating sheet 33B and the feeding rollers 43A, 43B are driven at a predetermined timing to cut out the first sheet 4 and the second sheet 5 without cutting the sheets 2,

When the leading end of the first sheet 4 reaches between the nip rollers 71A and 71B, the nip rollers 71A and 71B are closed and the feeding rollers 33A and 33B are opened And the first sheet 4 is opened. Similarly, when the leading end of the second sheet 5 reaches between the nip rollers 81A and 81B, the nip rollers 81A and 81B are closed and the feeding rollers 43A and 43B are opened And the second sheet 5 is opened.

If the winding of the separating sheets 2 and 3 by the winding core 13 is continued in this state, the first sheet 4 and the second sheet 5 are separated from each other by the frictional force between the separating sheets 2 and 3 And is pulled toward the core 13 so as to be pulled by the separating sheets 2 and 3. [

The winding of the end portions of the separation sheets 2 and 3 by the core 13 is completed and the ends of the first sheet 4 and the second sheet 5 are conveyed to the first conveying chute 14A 14B and the second conveying chuck 15A, 15B.

When the leading ends of the first sheet 4 and the second sheet 5 reach the initial positions of the first conveying chucks 14A and 14B and the second conveying chucks 15A and 15B respectively, Stop. The first conveying chuck 14A and 14B grasp the first sheet aggregate 2 and 4 related to the winding of the succeeding winding 1 and the second conveying chute 15A and 15B hold the next The second sheet aggregates 3, 5 associated with the winding of the winding body 1 are gripped.

On the other hand, in the core 13, when the winding of the end portions of the separation sheets 2 and 3 is completed, the pressing roller approaches the core 13, and the end portions of the separation sheets 2 and 3 are pressed .

In this state, the separation sheet cutters 16 and 17 are operated. The separating sheet 2 is cut between the core 13 and the first conveying chuck 14A and 14B and the separation sheet 3 is separated between the core 13 and the second conveying chuck 15A and 15B Is cut.

After the cutting, the core 13 is rotated while the end portions of the separation sheets 2 and 3 are pressed together with the fixing tape held by suction by the pressing rollers. Thus, the pressing roller is driven to completely wind the end portions of the separating sheets 2 and 3 without being disturbed (unraveled), and the fixing tape is adhered to the end portions of the separating sheets 2 and 3 And stops winding. As a result, the winding work of the various sheets 2 to 5 is completed, and the winding body 1 is completed.

Next, a procedure for pressing the rolled body 1 in a flat shape using the press apparatus 90 will be described.

When the winding of the winding body 1 by the winding device 10 is completed, the first peeling chuck 23 and the second peeling chuck 24 are wound around the core (as shown in Fig. 8 13) into the groove portions (25, 26) of the winding body (1). In this state, the first pressing claw 20A and the second pressing claw 20B are separated from the core 13. Thereafter, the first peeling chuck 23 and the second peeling chuck 24 are moved to remove the winding body 1 from the winding core 13.

Subsequently, the first peeling chuck 23 and the second peeling chuck 24 are moved to the press apparatus 90, and the rolled body 1 is placed between the press plates 91, 92. The relative positional relationship between the peeling chucks 23 and 24 is changed and the both peeling chucks 23 and 24 are sandwiched between the first positioning member 73 and the second positioning member 74 , The position fixation of the winding body 1 is performed. Thereafter, the middle plate 95 is inserted into the center of the winding body 1.

In this state, as shown in Fig. 8 (b), the press plates 91 and 92 are brought close to each other, and a temporary press is performed. As a result, the non-stacking portion 4b (between the two stacking portions 4a and 4a adjacent to each other in the sheet longitudinal direction of the first sheet 4 and the second sheet 5 and between the stacking portions 5a and 5a) , 5b are folded into a fold center line, and the winding body 1 is crushed (crushed). In other words, the positions of the non-stack portions 4b and 5b are defined as the curved portions 1b of the winding body 1.

Thereafter, in the state where the press plates 91 and 92 are separated from each other, the grasping by the peeling chucks 23 and 24 is released, and the middle plate 95 is separated from the press plates 91 and 92 It is evacuated. Subsequently, as shown in Fig. 8 (c), the press plates 91 and 92 are brought close to each other to perform the main press. As a result, the winding body 1 is pressed in a completely flat shape, and the pressing process of the winding body 1 is completed.

The lengths of the non-stacking portions 4b and 5b on the first sheet 4 and the second sheet 5 can be set to a dimension having a margin in advance, (4) and the second sheet (5) on the first sheet (4) and the second sheet (5) by the first sensor (18) and the second sensor (19) 5a of the lamination portions 4a, 5a are detected by the first conveying chucks 14A, 14B and the second conveying chucks 15A, 15B on the winding starting end side of the lamination portions 4a, The first sheet 4 and the second sheet 5 are wound while aligning the end portions 4c and 5c to the first reference position K1 and the second reference position K2, respectively. This makes it possible to accurately position the plurality of laminated portions 4a and 5a without being affected by manufacturing errors of the laminated portions 4a and 5a on the first sheet 4 and the second sheet 5, I can go straight. As a result, it is possible to improve the quality of the winding body 1 in which the plurality of stacked portions 4a and 5a are stacked.

In the present embodiment, the first pressing claw 20A, the second pressing claw 20B, the sensors 18 and 19, the reference positions K1 and K2, and the transfer chucks 14A and 14B, 15A and 15B, Are arranged at intervals of 180 degrees in the rotating direction of the core (13). In other words, they are arranged so as to be point symmetrical with respect to each other with the center axis 13a of the core 13 as the center. Thus, the positioning of the first sheet 4 and the positioning of the second sheet 5 can be performed simultaneously (during one stop). As a result, it is possible to reduce the number of times of stopping the core 13 for positioning the first sheet 4 and the second sheet 5, thereby improving the speed of the winding device 10 and further improving the productivity There is a number.

In this embodiment, the core 13 has a pair of arc-shaped surfaces 13b opposed to each other with the central axis 13a interposed therebetween, and a pair of planar surfaces 13b opposed to each other with the central axis 13a therebetween. (13c). As a result, as compared with the case where the first sheet 4 and the second sheet 5 are wound by using, for example, a flat-plate-shaped winding core in manufacturing the same winding body 1, It is possible to suppress the rattling of the first sheet 4 and the second sheet 5 during winding and to reduce the size of the winding device 10 because the turning radius can be made smaller.

Further, the present invention is not limited to the description of the above embodiment, and the following description is also applicable. Needless to say, other applications and modifications that are not illustrated in the following are also possible.

(a) In the above embodiment, the first sheet 4 and the second sheet 5 are employed as the strip-shaped sheets wound by the winding device 10. [ The first sheet 4 is made of a metal sheet such as an aluminum foil or the like and a positive electrode active material coated with a positive electrode active material as a laminated portion 4a, (Negative electrode) active material is applied as a laminate portion 5a on a metal sheet such as a copper foil or the like, and the separator sheets 2 and 3 may be a separator made of an insulating material. As a result, it is possible to manufacture a capacitor for a secondary battery, a capacitor and the like.

(b) In the above-described embodiment, the rolled wound body 1 is manufactured so that the first sheet 4 and the second sheet 5 are superimposed on each other. However, the present invention is not limited to this, A configuration may be employed in which the winding body is manufactured by winding one sheet.

(c) The configurations of the first sheet 4 and the second sheet 5 are not limited to the above-described embodiments, and other configurations may be employed.

For example, in the above-described embodiment, the laminated portions 4a and 5a are formed on both the front and back surfaces of the first sheet 4 and the second sheet 5, but the present invention is not limited to this, 5a may be formed on only one side of the first sheet 4 and the second sheet 5. In this case,

Although the laminated portions 4a and 5a of the first sheet 4 and the second sheet 5 are formed in a square shape in plan view in the above embodiment, For example, it may be configured as a rectangular shape in a plan view or a triangular shape in a plan view as well as a rectangular shape in a plan view.

It is not necessary that the laminated portions of the first sheet and the second sheet have the same shape in the same sheet.

(d) The shape of the core 13 (the winding shape of the winding 1) is not limited to the above-described embodiment, but may be, for example, a noncircular shape such as an ellipse in cross section or a rhombic cross section, ), As well as a circular rolled body 1 may be pressed to obtain a rolled body 1 having a flat shape.

However, in order to press the first sheet 4 and the second sheet 5 stably or to suppress displacement of the lamination portions 4a and 5a, as in the above-described embodiment, And the first sheet 4 and the second sheet 5 are pressed by the flat portion or the lamination portions 4a and 5a are aligned with each other.

In the circumferential surface portion of the winding core, at least a concave portion concave to be recessed toward the radial direction rotation axis side of the winding core is provided, and a first sheet aggregate (hereinafter referred to as " 2 and 4 and the second sheet aggregates 3 and 5 toward the recesses so that the first sheet aggregates 2 and 4 and the second sheet aggregates 3 and 5 are wound by a predetermined length The first sheet aggregate (2, 4) and the second sheet aggregate (3, 5) wound around the core may be recessed toward the recess every time.

More specifically, for example, as shown in Fig. 9, a pair of arc-shaped concave portions 97b opposed to each other with the central axis 97a therebetween, A winding core 97 composed of a pair of opposed planar portions 97c may be employed.

9 (a), the core 97 is rotated 180 degrees from the initial state, and the first sheet aggregates 2, 4 and the second sheet aggregates 3, 5 are rotated by 180 degrees, The first sheet aggregates 2 and 4 and the second sheet aggregates 3 and 5 are aligned in the same manner as in the above embodiment after the predetermined length is wound so as to be convex toward the radially outer side of the core 97.

Subsequently, as shown in Fig. 9 (b), the pressing member 98 serving as the pressing means is driven so that the wound first sheet aggregates 2, 4 and the second sheet aggregates 3, 5 are concave So as to pit the portion 97b.

9 (c), the pressure member 98 is separated and the core 97 is again rotated by 180 degrees so that the first sheet aggregate 2, 4 and the second sheet aggregate 2, (3, 5) is wound by a predetermined length so as to be convex toward the outside in the radial direction of the core (97). Thereafter, by repeating the above-described operation, the first sheet aggregate 2, 4 and the second sheet aggregate 3, 5 are wound around the core 97.
