Description

Device for processing a strip substrate with a liquid

The present invention relates to a device for processing a tape-shaped substrate in a liquid, the device comprising a transport system for transporting a strip-shaped substrate, the transport system comprising a winding system for winding at least one winding, around the transport system, The strip substrate is introduced into a spiral path, and the winding system includes: a first pulley mechanism rotatable about a first rotating shaft, and a portion of the circumference of the first pulley mechanism is guided by a first deflection angle The at least one winding of the substrate is wound around a portion of the circumference of the first pulley mechanism; and the second pulley mechanism is configured to guide the strip substrate around a portion of the circumference of the second pulley mechanism to a second deflection angle At least one winding around a portion of a circumference of the second pulley mechanism; the second pulley mechanism includes a second pulley that is rotatable about a first rotation axis for each winding; the device further A liquid bath is included wherein the ribbon substrate extends through the liquid in the liquid reservoir for at least a portion of the length of the at least one winding.

German Patent Publication No. DE 20 34 751 discloses an apparatus for electroplating metal wires. In the device, the metal wire is guided around a driving roller and a roller disposed below the driving roller, and is introduced into a spiral path. The drive roller is provided with a circumferential groove for each winding, and the lower roller includes an independently rotatable guide wheel for each winding, and the guide wheels are also each provided with a circumferential groove for a wire winding. . The central axes of the drive roller and the lower roller (and therefore the guide wheels) are oriented horizontally and parallel to each other. The lower roller is configured for first-class power In the tank. More or less, it is mentioned in DE 20 34 751 that the device is also suitable for processing strip materials. However, an important disadvantage is that during the processing of the strip material, the higher stress may be generated laterally in the strip material during the processing of the strip substrate to the next groove in the spiral shape between the drive roller and the lower roller. . This stress may cause wrinkling or, even worse, cause cracks to form in the strip material, which may have a very negative effect on the plating process. Another disadvantage of using conventional devices is that the device is not suitable for plating on one side of the strip substrate. Since the strip substrate extends in the liquid in the liquid tank without contacting the lower roller, the strip substrate is processed on both sides, but the strip substrate is in contact with the lower roller in the liquid tank, that is, substantially on one side, That is, the outer treatment, therefore, in fact, this device is not suitable for electroplating on both sides of the strip substrate. The inner side of the process is damaged by the contact between the strip substrate and the lower roller, and the strip substrate is more likely to be displaced over the surface of the lower roller due to the above reasons, and thus the situation is even worse. For many reasons, the results result in layers deposited on the outside and inside of the strip substrate being different from each other.

Western Electric Technology Digest, No. 20, October 1970, XP002453277 XP001333208, "Multi-channel wire processing equipment" by Berkowski et al. also discloses a continuous spirally wound groove in a contact roller and a first group of sheaves. A wire processing device for a wheel of a second set of sheaves. The sheaves of each set of sheaves can be coaxially rotated about a common axis with respect to the axis of rotation of the contact roller. The sheaves of each set of sheaves have different diameters.

U.S. Patent No. 2,682,335 discloses a tape processing apparatus which uses two cylinders of equal diameter and length around which a strip is helically wound. The axis of one cylinder is angularly displaced relative to the axis of the other cylinder.

It is an object of the present invention to provide a device as referred to in the preamble whereby a strip substrate can be processed in a very small manner using a liquid, for which purpose the strip substrate moves in a helical transport path, and The stress occurring in the strip substrate is limited, and the risk of wrinkling or cracking of the strip substrate is minimized. To achieve this, the second rotation axis of each of the second pulleys is at an angle α with the first rotation axis. This leads to the following great advantage, that is, the strip substrate only has to be twisted around a neutral wire to a limited extent, and depending on the nature of the material and the size of the strip substrate, the tensile force and pressure of the strip substrate in the transverse direction of the longitudinal direction will be low. The risk of wrinkling or cracking is minimal, or even all can be ruled out. In addition, the tendency of the strip substrate to laterally displace on the first pulley mechanism or the second pulley mechanism can be prevented, which tends to cause an extra load on the longitudinal edge of the strip substrate, which may be due to the liquid processing of the strip substrate. Causes damage to the material deposited thereon.

In order to increase the capacity, preferably, the second pulley mechanism has a plurality of second pulleys.

Moreover, the second pulleys are preferably of equal diameter. This provides the advantage that the winding system includes only the first pulley mechanism and the second pulley mechanism, and does not include any additional pulley mechanism such as the third pulley mechanism in a preferred embodiment to be described later. In this case, an extremely precise deflection angle of, for example, 180 degrees of the second pulley can achieve a bearing with excellent control of the strip substrate against the associated pulley mechanism. As a result, this results in a minimum mechanical load acting on the strip substrate.

For the reason of the structural simplicity, it is preferable that the second rotation axes associated with the individual second pulleys extend in parallel with each other. Therefore, the preferred embodiment eliminates the possibility that the second rotating shafts associated with the individual second pulleys are in line with each other, which may result in a strip substrate material in terms of preventing internal (lateral) stress of the strip substrate. The guidance is lower than the best.

Further, in order to improve the above advantages, it is preferable that the first pulley mechanism has the first diameter D1 at the position where the at least one winding is guided by the first pulley mechanism, and each of the second pulleys is wound by the first pulley. The guided position has a second diameter D2, wherein the second diameter D2 is larger than the first diameter D1, and it is further preferable that the size of the second diameter D2 is equal to the first diameter D1 divided by cos(α) size.

According to a preferred embodiment of the invention, in particular the winding system comprises only the first pulley mechanism and the second pulley mechanism, and does not comprise a third pulley mechanism, such as in a preferred embodiment, which will be described later. For any additional pulley mechanism, the first deflection angle and the second deflection angle are both 180 degrees, because this can be achieved in a simple manner. The direction of the strip substrate from the first pulley mechanism to the second pulley mechanism is parallel to the strip substrate. The direction of the pulley mechanism is away from the direction of the second pulley mechanism, although it is located at the height of the next winding.

In order to achieve a compact construction of the apparatus of the present invention, it is advantageous for the winding system to include a third pulley mechanism for guiding a portion of the circumference of the third pulley mechanism to a third deflection angle for guiding the strip substrate At least one winding, the third pulley mechanism includes a third pulley for each winding that is rotatable about a third rotation axis, and each of the third pulleys extends parallel to an associated second pulley, wherein further Preferably, the sum of the first deflection angle and the second deflection angle The angle is 180 degrees, and/or the second pulley mechanism and the third pulley mechanism are both at the same distance from the first pulley mechanism.

Depending on the application of the present invention, it may be highly advantageous that the liquid bath is disposed between the first pulley mechanism and the second pulley mechanism, wherein the substrate material extends linearly in the liquid tank, and the substrate material can be borrowed from the liquid tank. Multi-side treatment of liquids.

Alternatively, and particularly where the strip substrate is only treated on one side, it is advantageous if the liquid bath extends over a portion of the first deflection angle on the outer side of the first pulley mechanism.

To be precise, in order to process the strip substrate on one side, it is preferable that the first pulley mechanism forms a mask in the liquid tank facing the strip substrate side of the first pulley mechanism in the liquid tank. The substrate is made of a liquid, and the strip substrate is processed only on the side away from the first pulley mechanism.

A good connection of the strip substrate to the first pulley mechanism can be achieved in an advantageous manner, ie the first pulley mechanism comprises a contact surface for each winding, the contact surface being inclined upwards on the longitudinal edge of the strip substrate. It is ensured that the longitudinal edge appropriately abuts the upwardly inclined portion of the contact surface, and the pressure applied to the strip substrate by the hydraulic pressure of the liquid of the liquid tank and the tensile stress in the strip substrate contribute to such abutment, and the guarantee is ensured. Liquid tight seal.

In particular, in order to electrochemically process the strip substrate with a liquid, it is preferred that the first pulley mechanism includes a groove having a bottom portion and two bottom portions for the winding upright edges, wherein the strip substrate The bottom is abutted and the longitudinal edges of the strip substrate preferably do not contact the upstanding edges. The erect edges in turn contribute to the homogenization of the electric field within which electrochemical treatment occurs.

To facilitate the uniformization of the electric field, preferably in the longitudinal direction of the strip substrate There is a gap of up to 1 mm between the edge and the upright edge of the groove.

In particular, if the supply of the strip substrate occurs in a laterally perpendicular orientation of the strip substrate, for example, the strip substrate is unwound from a roller having a vertical axis of rotation, preferably the first axis has a vertical Orientation or an orientation that deviates by a maximum of 10 degrees. Another important advantage is that, because at least substantially due to the first axis of rotation, and preferably also the vertical orientation of the second axis of rotation, the windings will extend above each other and for maintenance work, such as replacing the electrolyte The anode material in the tank is easy to enter and exit the space on the inside or outside of the winding.

However, alternatively, if the first rotating shaft has a horizontal orientation, it may be very advantageous. In this case, the strip-shaped substrate can be introduced into the lead-out liquid tank from above, and the strip-shaped substrate does not need to enter or leave the liquid tank. Any facility to seal the tank, the tank can be of simple construction.

Particularly in the case where the first rotating shaft has at least a substantially vertical orientation, preferably at least one channel is disposed on at least one wall of the liquid tank, the strip substrate can pass through the passage, and, preferably, the passage is configured The strip substrate is allowed to pass without being in contact therewith. The latter aspect has the advantage that the strip substrate passes through the passage on one of the walls of the liquid tank without adversely affecting the treatment of the strip substrate by the liquid.

Preferably, the device is provided with a drop of disc on the side of the passage away from the interior of the tank.

Still preferably, a circulation mechanism is provided which, in combination with the drop tray, returns the liquid entering the drip tray back to the tank via a passage, and the liquid can be treated as efficiently as possible.

According to a very important preferred embodiment of the invention, the winding system is arranged, and the strip substrate is introduced into a spiral path by a plurality of windings, around the winding system, wherein the first pulley mechanism and the second belt are arranged The wheel mechanism is configured to guide a plurality of windings spaced apart by a plurality of adjacent locations. Therefore, the treatment of the strip substrate with liquid can occur in a very small manner, but the stress occurring on the strip substrate is minimal.

The angle α is preferably between 2 and 30 degrees, wherein the optimum angle is also dependent on the nature of the material and the size of the strip substrate.

Further, in order to minimize the tensile stress and the occurrence of sliding in the strip substrate, it is generally preferred that the first pulley mechanism includes a one pulley mechanism that can be wound around each of the first rotating shafts. Rotation, wherein the individual first rotating shafts are coaxial. The advantage of the use of many individual first pulley mechanisms is that they do not have to be exactly angular velocity, and there is no need to compensate for the extension of the ribbon substrate that occurs when the strip substrate slides through the first pulley mechanism in the longitudinal direction of the strip substrate.

Further, in order to achieve the above advantages, preferably, the transport mechanism includes a drive mechanism for rotatably driving a single first pulley, and preferably, the single first pulley is an outermost first pulley. When the first rotating shaft has at least substantially vertical orientation, the outermost first pulley is formed by the lowermost pulley or the uppermost pulley of the first pulley mechanism.

In particular, if the strip substrate is treated with liquid only on one side, preferably the strip substrate is in contact with the pulley mechanism forming part of the winding system only on one side of the winding system. In this case, one side of the liquid treatment is located on the outer side, and the strip-shaped substrate abuts the pulley mechanism of the winding system on the inner side. The outer side of the strip substrate that has been treated with liquid will not be affected by the strip substrate and the pulley The contact of the organization is loaded.

The advantages of the present invention are particularly applicable to galvanic treatment of strip substrates. In this architecture, another preferred embodiment is characterized in that the liquid bath is a first-class electro-hydraulic tank.

The invention also relates to a combination of two of the above-described continuous devices of the invention wherein the strip substrate moves in the opposite direction as viewed parallel to the direction of the first axis of rotation of the individual device. In this manner, the strip substrate can be fed to the first device in the combination in a feed direction, wherein the first direction and the second direction are in line with each other, which makes the combination extremely suitable for incorporation into the production line.

According to another aspect of the present invention, there is provided a method of processing a strip substrate in a liquid comprising the steps of transporting a strip substrate through a liquid bath by a transport system comprising a winding system for Introducing the strip substrate into a spiral path by winding at least one winding system, the winding system comprising: a first pulley mechanism rotatable about a first rotation axis for winding the first a portion of the circumference of the pulley mechanism guides at least one winding of the strip substrate at a first deflection angle, and a second pulley mechanism for forming a second deflection angle around a portion of the circumference of the second pulley mechanism At least one winding of the guiding strip substrate, the second pulley mechanism comprising a second pulley that is rotatable about a second rotating shaft for each winding, the device further comprising a liquid tank, wherein the strip shape The substrate passes through the liquid in the liquid bath and extends over at least a portion of the length of the at least one winding, and wherein the second rotating shaft of each of the second pulleys forms an angle a with the first rotating shaft. The advantages obtained with this device have been explained in the above description of the invention.

In order to utilize the available space as efficiently as possible, the preferred tape-shaped substrate is introduced into a spiral path around a winding system having a plurality of windings.

The method of the invention is particularly suitable for use in the manufacture of solar panels. Conventional techniques typically use a tantalum panel as the substrate material. Alternatively, a strip-shaped substrate made of a metal such as copper or stainless steel, on which at least one layer of indium, selenium or gallium is deposited, may alternatively be used. In particular, in this architecture, the preferred strip-shaped substrate is subjected to a galvanic treatment, the strip-shaped substrate is made of stainless steel or copper, and/or a layer of indium, selenium or gallium is deposited on the strip substrate in the liquid bath.

In general, a preferred tape-shaped substrate passes through the liquid bath at a rate of 2 meters per minute.

The invention will now be explained in more detail by way of the following description of a preferred embodiment of the apparatus of the invention.

Figures 1a and 1b show schematically a production line 1 for electrolytically/currently electroplating a flexible strip substrate 2. The strip-shaped substrate 2 is supplied to the production line 1 from the supply side 3 after being treated with the electrolytic solution by the production line 1, and is discharged from the production line 1 on the discharge side 4. On the supply side 3, the strip substrate 2 can be unwound, for example, from a supply spool (not shown), and the strip substrate 2 is wound on the discharge side 4 to a storage reel (not shown). The strip-shaped substrate 2 is aligned with each other on the supply side, the discharge side, and the center of the line 1, indicated by 9. The strip substrate 2 is oriented such that the lateral direction of the strip substrate 2 extends in the vertical direction at the supply side 3 and the discharge side 4.

Production line 1 consists of four continuous galvanic production units, which are considered to be A preferred embodiment of the inventive device. The first two production units 5, 6 are preferred embodiments of the first type of the apparatus, and the last two production units 7, 8 are preferred embodiments of the second type of the apparatus. The first type production unit 5, 6 and the second type production unit 7, 8 will be described in more detail later with reference to Figs. 2, 3 and Figs. 4-11, respectively.

The production unit 5 comprises a winding system 11 comprising a first pulley mechanism 12 and a second pulley mechanism 13. The first pulley mechanism 12 includes five first pulleys 14 having the same diameter D1, and the central axes thereof are oriented coaxially and vertically. The second pulley mechanism 13 includes five second pulleys 15 which also have the same diameter D2. As shown in Fig. 3, the second pulleys 15 are disposed directly above each other, but each has a central axis 16 at an angle a to the vertical. The central shafts 16 associated with the second pulley 15 extend parallel to each other. The second pulleys 15 are free to rotate about their central axis 16. For this purpose, the second pulley 15 is rotatably mounted to a fixedly disposed hub member 19 having a vertical central axis.

The strip-shaped substrate 2 sequentially passes over the pulleys 14, 15 of the first pulley mechanism 12 and the second pulley mechanism 13, respectively, and the deflection angle 15 around the first pulleys 14 and the second pulleys 15 is 180 degrees. The relative positions of the pulleys 14 and 15 are selected such that the position at which the yaw deflection angle starts at the point of the entrance 21 (Fig. 1c) on the second pulley 15 is at the same vertical height as the position at which the strip substrate 2 leaves the pulley 14. Further, the angle α and the diameter D2 are further selected, and if 俾(D2=D1/cos(α)) is the above-described deflection angle, the exit point 22 located at the end of the deflection angle of the second pulley 15 is the pulley 14 located above and above. (14' in Figure 1c) the same vertical height. As a result, the strip-shaped substrate 2 only extends between the continuous pulleys 14, 15, that is, only at an angle to the vertical line of the strip-shaped substrate. α is reversed, but the neutral line continues to extend exactly horizontally. In the preferred embodiment, the angle α is 3 degrees. The optimum angle depends in part on the nature of the material and the size of the strip substrate 2. Specifically, since the deflection angle of the second pulley 15 is 180 degrees, the strip substrate 2 is not only approaching the second pulley 15 in the horizontal direction but also deflecting 180 degrees, although the second pulley 15 is obliquely oriented. Thereafter, the second pulley 15 is just separated in the horizontal direction.

An important advantage of selecting the size and orientation as described above is that, except for slightly pulling the tensile force along the longitudinal direction of the strip-shaped substrate 2, only the pulleys 14, 15 are subjected to the torsion. More specifically, no force acts laterally on the plane of the strip substrate 2, which force may cause the strip substrate 2 to move across the pulleys 14, 15 in a plane perpendicular to the longitudinal direction of the strip substrate 2, which results in a belt The height of the shaped substrate 2 is stably guided and significantly reduces or even eliminates any tendency to wrinkle.

The drive mechanism 25 is provided below the first pulley mechanism 12 to drive the strip substrate 2, and the drive mechanism rotates only the uppermost pulley 14 of the first pulley mechanism 12. On the one hand, the pulleys 14, 15 are like being pulled by the strip-shaped substrate 2, the strip-shaped substrate 2 being over the individual pulleys 14, 15 by some pulling force, and on the other hand, the limited friction between the pulleys 14, 15 drive. Since the strip-shaped substrate 2 is inevitably elongated, the various pulleys 14, 15 are not moved at the same angular velocity, and substantially no sliding between the strip-shaped substrate 2 and the pulleys 14, 15 is required. Therefore, such sliding occurs to a very limited extent, but occurs between adjacent pulleys 14,15.

2 shows the manner in which the winding system 5 is housed in a box type container 27, and the end faces of the container 27 are provided on the supply side 3 and the discharge side 4, respectively. The openings 28, 29 allow the strip substrate 2 to pass through the openings 28, 29, wherein the strip substrate 2 extends in the openings 28, 29 in the same vertical plane, except that the strip substrate 2 is open in the opening 29. 28 higher. As will be appreciated by those skilled in the art, as seen in Figure 1b, this height is again completely eliminated from the production unit 6.

An electrolytic cell 30 is disposed halfway between the lengths of the box-shaped containers 27, between the pulley mechanisms 12, 13 in which an electrolyte reaches the liquid above the uppermost winding upper side of the strip-shaped substrate 2 in use. Face 31. Channels 34, 35 and 36, 37 are provided at the end walls 32, 33 of the electrolytic cell 30, which have a greater width than would be expected in Figure 2. In practice, the width of the channels 34-37 is selected and the ribbon substrate 2 can pass through the channels 34-37 without being in contact therewith.

The drip trays 38, 39 are provided between the walls 32, 33 and the first pulley mechanism 12 and the second pulley mechanism 13, respectively, to receive the liquid leaking from the grooves from the grooves 30 through the passages 34-37. The liquid is returned to the tank 30 by a circulation mechanism (not shown).

The air blowing mechanisms 40, 41 are disposed at the positions of the channels 34 and 37 in the drip trays 38, 3, that is, the strip substrate 2 leaves the slot 30 to air dry the strip substrate 2, and the strip substrate 2 is dry or at least slightly In the dry state, it comes into contact with one of the first pulley 14 or the second pulley 15.

It is known to those skilled in the art that a first type of production unit 5 can be electrochemically deposited on either side of the strip substrate 2 at a high production rate using a first type of production unit 5 in a very small device. Those skilled in the art are well acquainted with the electrolytic treatment and therefore need no further explanation. Even if it is not necessary, please only Note that a positive material may be present in the tank 30, which dissolves in the liquid in the tank and settles on the sides of the strip substrate 2. Alternatively, the positive material may also dissolve outside of the tank 30. To stimulate precipitation of the positive material, a negative voltage is applied to the strip substrate 2 via a contact mechanism (not shown) that may, for example, form part of the pulleys 14, 15.

The production unit 6 is mostly similar to the production unit 5, with the difference that the vertical variation in the path of travel of the strip substrate 2 occurs in the opposite direction of the individual production units 5, 6, which is why in the production unit 6, only the The lowermost pulley 14 of the pulley mechanism 12 is driven instead of the reason why the lowermost pulley 14 is driven as in the example of the production unit 5.

Figures 4-11 show in more detail one of the production units 7 of the second preferred embodiment. In view of the great similarities of the production units 7, 8, it is almost unnecessary to explain the production unit 8 to those skilled in the art who have studied the description of the production unit 7.

The production unit 7 includes a winding system 51 including a first pulley mechanism 52, a second pulley mechanism 53, and a third pulley mechanism 54. The first pulley mechanism 52 corresponds to the first pulley mechanism 12 of the production unit 5 in the sense that a plurality of first pulleys 55 are included, and the central axis thereof is coaxial and vertically oriented. Only the uppermost pulley 55 is rotatably driven by the drive motor 56.

The second pulley mechanism 53 and the third pulley mechanism 54 sequentially include a plurality of the second pulleys 57 and the third pulleys 58 in this order, and the respective pulley mechanisms 53 and 54 are directly disposed above each other. The upper portion corresponds to the second pulley mechanism 13 of the production unit 5. The central axes associated with the second pulley 57 and the third pulley 58 each have an angle α of about 3 degrees with respect to the vertical line and extend in parallel with each other. The second pulley 57 and the third pulley 58 are positioned relative to each other, 俾 In the view of Fig. 11, the individual pulleys 57, 58 are in line with each other. The pulleys 57, 58 are further provided with a contact mechanism (not shown) for applying a negative voltage to the strip substrate 2 for plating treatment.

The strip-shaped substrate 2 alternately passes over the pulleys of the individual pulley mechanisms 52, 53, 54 in a deflection angle of 180 degrees around the first pulley 55 and a deflection angle of 90 degrees around the second pulley 57 and the third pulley 58. 55, 57, 58. Therefore, the deflection angles of the second pulley 57 and the third pulley 58 are added to be 180 degrees.

The relative positions of the pulleys 55 and 57 are selected, and the ribbon-shaped substrate 2 (the neutral line) extends between the continuous pulleys 55, 57, i.e., just horizontally, and is only about an angle α, and is twisted within this range. Since the continuous pulleys 57 and 58 are in line with each other (Fig. 11), and the individual deflection angles are 90 degrees, the strip substrate 2 is inclined upward (without any torque) between the pulleys 57, 58 and then again to the pulley 58. The 90 degree deflection angle end exits the pulley 58 in the right direction. Thus, in fact, the pulleys 57, 58 together have the same function as the pulley 15 of the associated production unit 5, i.e., moving the strip substrate 2 to a higher level (or, for the production units 6, 8 At a low height, the crucible forms a second winding without any lateral force being brewed in the strip substrate 2. In contrast to the use of a pulley mechanism 13, the use of the two pulley mechanisms 53, 54 is particularly advantageous in that the use of the two pulley mechanisms 53, 54 requires a limited amount of space.

The winding system 51 is housed in a square box type container 71. Openings 61 (Fig. 6), 62 (Fig. 4) are disposed in line with each other in the opposing wall of the box-shaped container 71 to allow the strip-shaped substrate 2 to pass. An at least substantially C-shaped liquid channel 72 is provided at the center of the container 71, and the first pulley 55 has an outer side of one of the 180° deflection angles. C-shaped liquid is formed on the outer side of the first pulley mechanism 52 A portion of the upstanding wall on the inside of the trough 72, and a portion of the outer side wall of the C-shaped trough 72 is indicated by reference numeral 73. The circumference of the C-shaped reservoir 72 is further defined by end walls 74 that extend from the first pulley mechanism 52 and join the outer wall 73.

An anode basket 75, for example, spherical, is disposed in the C-shaped liquid tank 72 to hold the anode material. The anode material is anodically connected via an anode connector 76. In use, the C-shaped liquid tank 72 is filled with the electrolyte to a height higher than the uppermost winding of the strip substrate 2. In the C-shaped liquid tank 72, the curved and horizontally extending shielding belts 77 extending along a larger portion of the length of the C-shaped liquid tank 72 are disposed at a shorter distance from the outer sides of the pulleys 55, and the shielding belts 77 can pass through. The transition between them.

As particularly shown in Figures 7, 9, and 10, the first pulley 55 is circumferentially provided with grooves 79, the bottom of which is formed of an elastic, band-shaped shield 80 which is along the groove. The groove 79 extends all the way. The mask body 80 is made of, for example, rubber. The width of the groove 79 is slightly larger than the width of the strip substrate 2, and as a result, a gap having a width of about 0.3 mm appears between the upright wall of the groove 79 and the longitudinal edge of the strip substrate 2. One of the mask bodies 80 abutting the strip substrate 2 has an upward inclined portion 82 (refer to FIG. 10) on the longitudinal edge, which starts within the width of the strip substrate 2, thereby ensuring the strip substrate 2 and As a result, the mask body 80 is properly abutted. As a result, the electrolytic treatment of the strip substrate 2 occurs only on the outer side of the strip substrate 2, and the strip substrate 2 is much thicker than the actual user in Figs. 7, 9, and 10.

On the side remote from one side of the C-shaped liquid tank 72, the production unit 7 is provided with a drip pan 91 which in fact forms a common drip tray below the first pulley 52. The drip tray is adapted to receive from the C-shaped liquid channel 72 through the inwardly directed end of the end wall 74 and the first pulley The gap between the outer sides of 52 leaks out of the liquid of the C-shaped liquid tank 72. The liquid is withdrawn into the C-shaped liquid tank 72 by a circulation mechanism (not shown).

Sealing plates 83 are provided on the outer sides of the first pulley 52, which are located at the segments shown in Figs. 8, 9, and 10 and are adjacent to the end face walls 74, and the strip-shaped substrate 2 can pass therethrough without being in contact therewith. The sealing plates 83 are provided with projections 84 that extend into the grooves 79. The size and position of the sealing plates 83 are defined as a small gap between the strip-shaped substrate 2 and the first pulley 52 including the sealing plates 83. The sealing plates 83 adjacent the end face walls 74 are intended to reduce leakage from the C-shaped liquid channel 72, while the sealing plates 83 shown in Figures 8, 9, 10 are intended to prevent splashing liquid from passing through the drip tray 91 through such seals.

The skilled person understands the operation and construction of the production unit 8 after the above description of the production unit 7. In the production unit 8, the strip substrate 2 returns to the same vertical height as the strip substrate 2 is close to the height of the production unit 7. In the production unit 8, the lowermost first pulley 55 is rotatably driven in place of the uppermost first pulley 55.

The invention is not limited to the preferred embodiments of the invention described above, but the scope of the invention is first determined by the scope of the appended claims. Alternatively, it is also possible to use, for example, the first, second and possibly third pulley mechanisms within the framework of the invention, such that the associated axis of rotation is horizontal rather than (substantially) vertically oriented. The second rotating shaft (the shafts) and, if possible, the third rotating shaft (the shafts) comprise an angle formed by the first rotating shaft from the top view, the second pulley mechanism and possibly the third pulley mechanism It is preferably above the first pulley mechanism. Although a winding system has been consistently mentioned in the above description of the preferred embodiment, the tape substrate is wound in a number of windings around the roll. Around the system, into a spiral path, but alternatively, for example (but not exclusively) to pass the strip substrate through a rinse bath, it is highly likely that a winding system, strip substrate, is used within the architecture of the present invention. It is wound around the winding system and introduced into a spiral path.
