Description

The present invention provides, for example, a compress sheet to be attached to the body for treatment of bruises, bruises, stiff shoulders, etc., and an adhesive tape agent cut to a certain size, such as a plaster sheet, a heating sheet, and other cards. The present invention relates to an adhesive tape preparation apparatus for manufacturing.

The adhesive tape agent is a tape agent piece that is detachably attached to a liner. In manufacturing such an adhesive tape agent piece, the adhesive agent is applied to a tape base material made of a strip-shaped continuum. A cut is made in the laminated tape material to form a series of individually arranged tape pieces, and each of these continuous tape pieces is sequentially transferred onto the liner at regular intervals. Will be done.

To specifically explain the transfer operation of the liner in the conventional adhesive tape agent manufacturing apparatus, a continuous body of tape agent pieces having an adhesive adhesive agent having adhesiveness is continuously adsorbed on the outer peripheral surface of the raw material supply roll. In the region facing the liner support roll around which the liner is wound, each tape agent piece is transferred to the liner side and is put into a sticking state. The transfer operation of each tape agent piece at that time is performed, for example, by rotating the liner support roll at a peripheral speed faster than that of the raw material supply roll, and each tape agent piece moves to the liner side in the opposite region of both rolls. By being pulled, the tape agent pieces that were continuously adjacent to each other on the raw material supply roll are attached onto the liner at intervals of the difference in the transport speed.

At this time, in the following Patent Document 2 (Patent No. 5661212), the rotation of the raw material supply roll is controlled to an intermittent operation including a stop operation corresponding to the distance between the tape agent pieces, and the raw material is supplied. A configuration is adopted in which the gap S at the portion where the roll and the liner support roll are arranged facing each other is set to be the same as or smaller than the value (t1 + t2) obtained by adding the thickness t1 of the tape agent piece and the thickness t2 of the liner. (S ≦ t1 + t2). By doing so, it becomes possible to convey the liner and the tape agent piece at the same speed while keeping them in close contact with each other, and the behavior when the tape agent piece is transferred is stable, and the liner and the tape agent piece are separated from each other. The conventional air pools and bubbles are not formed between them.

As described above, according to the patented invention described above, it is possible to prevent the formation of air pools and air bubbles between the liner and the tape piece, but apart from the problem of such air pools and air bubbles. , When the adhesive agent attached to the tape base material has a high viscosity, the adhesive agent moves outward from the rear end of the tape agent piece due to the pressing force between the raw material supply roll and the liner support roll. There is a risk of it sticking out. If the adhesive agent "protrudes" to the outside, it may adhere to the surface of the raw material supply roll or the like and cause product stains. In addition, as such an adhesive agent "protrudes" to the outside, "wrinkles" may occur at the rear end portion of the tape base material due to the pressing force between the two rolls.

It is conceivable to dispose the raw material supply roll and the liner support roll separately from each other in order to solve the problem of "protrusion" of the adhesive agent and "wrinkle" of the tape base material. In that case, air pools and air bubbles are formed between the liner and the tape agent piece as in the conventional technique described above. That is, in addition to the problems of "air accumulation" and "bubbles" in the conventional device described above, the problem of "protrusion" and "wrinkles" when the adhesive agent has a high viscosity is taken into consideration, and the raw material is supplied. How much the gap S between the roll and the liner support roll facing each other is specifically set becomes an extremely important issue.

JP-A-2003-95502 Japanese Patent No. 5661212

The present invention satisfactorily prevents air from entering between the tape piece and the liner when the tape piece is transferred to the liner side at intervals, and "protrudes" the adhesive agent. It is an object of the present invention to provide an adhesive tape agent manufacturing apparatus capable of eliminating the occurrence of "wrinkles" and "wrinkles".

In order to solve the above problems, in the adhesive tape agent manufacturing apparatus according to the present invention, a tape agent raw material in which an adhesive agent is laminated on one surface of a tape base material made of a continuous strip-shaped body is used to remove the adhesive agent from the outside. The raw material supply roll that is rotationally driven in one direction while being wound around the tape, and the adhesive agent of the tape agent raw material and the tape base material that are wound around the raw material supply roll are individually cut. A die roll for forming a continuum of parallel tape agent pieces and a liner support roll around which a film-like liner made of a continuous strip is wound are provided, and the raw material supply roll and the liner support roll are the tape. The tape agent pieces are placed facing each other with a predetermined gap S between the agent pieces and the liner, and the tape agent pieces are placed on the liner supported by the liner support roll at regular intervals. The raw material supply roll and the liner support in an adhesive tape manufacturing apparatus in which the raw material supply roll is controlled to perform an intermittent rotation operation including a stop operation corresponding to the interval so as to be transferred. The gap S in the portion facing the roll is the value (t1 + t2) obtained by adding the thickness t1 of the tape agent piece and the thickness t2 of the liner, and the maximum value of the fluctuation amount of the thickness of the adhesive agent. By being set to a value (t1 + t2 + Δtmax) to which Δtmax is added (S = t1 + t2 + Δtmax) , when the tape agent piece is transferred to the liner, the adhesive agent is used in the raw material supply roll. It also has a configuration in which it is maintained in a state of not being pressed by the liner support roll .

According to the adhesive tape agent manufacturing apparatus having such a configuration, when the tape agent piece is supplied from the raw material supply roll side to the liner side by the rotational operation of the raw material supply roll, the raw material supply roll is subsequently supplied. When the rotation operation of the tape agent piece is stopped, the operation of supplying the tape agent piece from the raw material supply roll to the liner side is temporarily stopped, and the movement distance of the liner while the supply operation of the tape agent piece is stopped is next. There is a certain distance between the tape and the tape piece supplied to the tape. When the tape agent piece is transferred to the liner side, the raw material supply roll and the liner support roll are rotated at substantially the same peripheral speed, so that the liner and the tape agent piece are conveyed at substantially the same speed and the tape is concerned. The behavior when the agent piece is transferred is stabilized, and the conventional air pool and air bubbles are not formed between the liner and the tape agent piece.

In addition, according to the adhesive tape agent manufacturing apparatus having the above-described configuration, when the tape agent piece is transferred, the tape agent piece and the liner come together at the opposite portion between the raw material supply roll and the liner support roll. Since the contact state is maintained lightly, the generation of air pools and air bubbles between the tape piece and the liner is reduced, and at the same time, the adhesive agent is suppressed by the facing arrangement portion of the raw material supply roll and the liner support roll. It is possible to prevent the adhesive agent from sticking out to the outside of the tape piece, and to prevent wrinkles from being generated on the tape base material.

At this time, the raw material supply roll in the present invention may be provided with an air suction means for adsorbing the tape agent piece on the raw material supply roll.

As described above, in the adhesive tape agent manufacturing apparatus according to the present invention, a tape agent raw material in which an adhesive agent is laminated on the entire surface of one side of a tape base material made of a continuous strip is wrapped with the adhesive agent on the outside. After the tape agent piece is supplied to the liner side by the rotation operation of the raw material supply roll that rotates in one direction in the state, the rotation operation of the raw material supply roll is stopped, so that the tape agent piece to be supplied next The transport is performed with a certain interval between the two, and in particular, the gap S between the raw material supply roll and the liner support roll is the value obtained by adding the thickness t1 of the tape agent piece and the thickness t2 of the liner. It is set to a value (t1 + t2 + Δtmax) obtained by adding the maximum value Δtmax of the thickness fluctuation amount of the adhesive agent to (t1 + t2), and the tape agent piece and the liner are kept in a light contact state where they do not separate from each other. By rotating and driving at the same peripheral speed, the behavior of the transfer operation of the tape agent piece is stabilized, the generation of air pools and air bubbles between the liner and the tape agent piece is reduced, and at the same time, the tape agent piece is transferred. sticky drug held down state without an adhesive agent by to it without protruding outwardly of the tape preparation piece, and in which wrinkles in the tape base material is constituted so as not to generate the time of Therefore, the reliability of the adhesive tape agent manufacturing apparatus can be significantly improved.

It is a plane explanatory view which showed the manufacturing process of the adhesive tape agent manufactured by the adhesive tape agent manufacturing apparatus shown in FIG. It is a side explanatory view which showed the process of the transfer operation of the adhesive tape agent manufactured by the adhesive tape agent manufacturing apparatus shown in FIG. It is a block diagram which showed an example of the transfer operation control part (control) which controls various operations in the adhesive tape agent manufacturing apparatus shown in FIG.

Hereinafter, the adhesive tape agent manufacturing apparatus according to the embodiment of the present invention will be described in detail with reference to the drawings.

The adhesive tape agent manufacturing apparatus according to the embodiment shown in FIG. 1 includes a cutting / bonding unit 1 which is a main component thereof, with respect to the cutting / bonding unit 1 from the upper side in the drawing. The tape agent raw material 2 forming a continuous strip is continuously supplied, and the film-shaped liner 3 forming a continuous strip as shown in FIG. 2B is continuously supplied from the lower side of the drawing. Is supplied to. The tape agent raw material 2 and the liner 3 supplied to the cutting / bonding unit 1 are subjected to a cutting / bonding process as described later inside the cutting / bonding unit 1, whereby FIG. 2 (d) ) Is formed and sent out as a continuum of the adhesive tape agent 4.

The continuous body of the adhesive tape agent 4 sent out from the cutting / bonding unit 1 is sent to the cover tape bonding unit 5, and in the cover tape bonding unit 5, the continuous body of the adhesive tape agent 4 described above is used. On the other hand, the cover tape 5a is attached as shown in FIGS. 2 (e) and 2 (f). It is then fed into the entire cut unit 6 where it is molded into the final individual adhesive tape agent 4.

Here, the tape agent raw material 2 supplied to the cutting / bonding unit 1 is formed by laminating the adhesive agent 2b on the entire surface of one side of the tape base material 2a made of a continuous strip. Therefore, a release paper 2c, which is also made of a continuous strip, is detachably attached to the outer surface of the adhesive agent 2b.

On the other hand, the cutting / bonding unit 1 includes a raw material supply roll (vacuum anvil roll in FIG. 1) 1a that rotates counterclockwise in FIG. 1, and the outer peripheral surface of the raw material supply roll 1a. The above-mentioned tape agent raw material 2 is supplied via the supply tension roll 1b so as to be in line with the above. Further, in the rotation direction of the raw material supply roll 1a, the peeling claw 1c, the die roll 1d, and the liner support roll 1e face the outer peripheral surface of the raw material supply roll 1a on the downstream side of the supply tension roll 1b described above. They are arranged in order.

Then, as described above, in the tape agent raw material 2 supplied on the outer peripheral surface of the raw material supply roll 1a via the supply tension roll 1b, the tape base material 2a comes into contact with the outer peripheral surface of the raw material supply roll 1a. It is wrapped in the state that it is. The tape agent raw material 2 wound on the outer peripheral surface of the raw material supply roll 1a is supplied with the release paper 2c attached to the adhesive agent 2b facing outward. It is integrally conveyed as the roll 1a rotates.

At this time, a large number of suction holes (not shown) are formed on the outer peripheral surface of the raw material supply roll 1a, and appropriate suction means (not shown) are formed on both axial end surfaces of the raw material supply roll 1a. The suction hopper 1f connected to is fixed. The suction hopper 1f is arranged so as to form a concentric shape between the position where the supply tension roll 1b is arranged and the position where the liner support roll 1e is arranged, and the cross section orthogonal to the axial direction is substantially C. It has a hollow suction passage that forms a mold.

The continuum of the tape agent raw material 2 adsorbed on the outer peripheral surface of the raw material supply roll 1a by the suction force applied from the intake means is the raw material supply roll from the above-mentioned arrangement position of the supply tension roll 1b. It will be conveyed counterclockwise in FIG. 1 in accordance with the rotational operation of 1a, but when it is conveyed to the above-mentioned arrangement position of the peeling claw 1c, the tape is separated by the separating action of the peeling claw 1c. The release paper 2c forming the outermost layer of the agent raw material 2 is peeled off to the outer side. The peeled release paper 2c is wound up and discarded outside the machine.

When the release paper 2c forming the outermost layer is peeled off in this way, the adhesive agent 2b on the tape base material 2a is exposed to the outside, and the tape in such a state is exposed. The continuous body of the agent raw material 2 is further conveyed counterclockwise in FIG. 1 as the raw material supply roll 1a rotates, and reaches a position facing the die roll 1d described above. The die roll 1d has a cutting edge on the outer peripheral surface of the die roll 1d, and has a structure in which the tape base material 2a and the adhesive agent 2b forming a continuum of the tape agent raw material 2 are cut out into a predetermined shape. It has been done.

More specifically, the cutting action of the die roll 1d on the tape agent raw material 2 described above cuts out a continuous body of the tape agent pieces 2A having a substantially rectangular plane as shown in FIG. 2 (a). Both side portions in the width direction with respect to the tape agent piece 2A are wound up as a continuous strip-shaped scrap piece and discharged to the outside of the machine.

As described above, the continuum of the tape agent pieces 2A cut out by the die roll 1d (see FIG. 2A) is adsorbed on the outer peripheral surface of the raw material supply roll 1a, and the raw material supply roll 1a is attached. The tape agent pieces 2A are conveyed according to the rotation operation, and the tape agent pieces 2A at the time of this transfer are in a state of being continuously arranged in the rotation direction of the raw material supply roll 1a, and the tape agent pieces 2A adjacent to each other in these transfer directions. As described above, the 2A and 2A are separated from each other by forming a cut due to the cutting action of the die roll 1d.

The continuous body of the tape agent pieces 2A (see FIG. 2A) that is conveyed while being adsorbed on the outer peripheral surface of the raw material supply roll 1a is arranged to face the lower end portion of the raw material supply roll 1a in the drawing. When the position facing the liner support roll 1e is reached, the tape agent pieces 2A are individually placed on the liner 3 (see FIG. 2B) by the cooperative action of the raw material supply roll 1a and the liner support roll 1e. The transfer operation is performed (see FIG. 2 (c)).

At this time, the above-mentioned liner 3 is formed of a pair of flexible strip-shaped film-like members, and the edges of the pair of the first liner 3a and the second liner 3b are partially polymerized. It has a configuration (see FIG. 2B). The first liner 3a and the second liner 3b are fed out from the first liner roll 7a and the second liner roll 7b provided in the liner supply device 7, and are supplied to the cutting / bonding unit 1.

That is, the first liner 3a and the second liner 3b unwound from each of the first and second liner rolls 7a and 7b2 described above are transported via the plurality of transport rolls 7c, but are cut and bonded. Immediately before being supplied to the unit 1, the alignment of the edge portion in the width direction is performed by the position regulating action of the edge controllers (EPC) 7d and 7d.

More specifically, as shown in FIG. 2B, the pair of the first liner 3a and the second liner 3b have a region in which the edge portions adjacent to each other overlap each other in the width direction. It is aligned by the edge controllers (EPC) 7d and 7d, and is fed from the liner tension roll 7e toward the liner support roll 1e in the cutting / bonding unit 1 in such a partially polymerized state.

As shown in FIG. 3A, the liner support roll 1e at this time is arranged so as to face the outer peripheral surface of the raw material supply roll 1a from the lower side via a constant gap S. There is. The liner support roll 1e is configured to be rotationally driven in the direction opposite to the raw material supply roll 1a (clockwise in FIG. 3) at a peripheral speed substantially equal to the peripheral speed of the raw material supply roll 1a. By such a rotational drive, the liner 3 described above is supplied toward the facing gap S with the raw material supply roll 1a.

The facing gap S formed between the liner support roll 1e and the raw material supply roll 1a is a tape agent piece on the raw material supply roll 1a side, particularly as shown in FIG. 3C. The thickness (t1) of the adhesive agent 2b forming a part of the tape agent piece 2A is added to the value (t1 + t2) obtained by adding the thickness t1 of 2A and the thickness t2 of the liner 3 on the liner support roll 1e side. It is set to a value (S = t1 + t2 + Δtmax) to which the maximum value (Δtmax) of the fluctuation amount (± Δt) of ′) is added.

That is, as described above, the thickness (t1') of the adhesive agent 2b laminated on one side of the tape base material 2a fluctuates more than other members due to changes in various production conditions and environmental conditions. The tape agent piece 2A having an amount (± Δt) along the transport direction and partially containing the adhesive agent 2b has a variation (t1 ′) in the thickness (t1 ′) of the adhesive agent 2b described above. While the thickness changes along the transport direction over ± Δt), the liner support roll 1e and the raw material supply roll 1a are fed into the facing gap S. Then, the maximum value of the fluctuation value in the direction in which the thickness (t1) of the tape agent piece 2A in the facing gap S becomes thick is set to Δtmax as described above.

The facing gap S between the liner support roll 1e and the raw material supply roll 1a has a dimensional relationship as described above with respect to the tape agent piece 2A having a thickness variation of the maximum value (Δtmax) in the thickening direction. S = t1 + t2 + Δtmax). By setting such a dimensional relationship, the liner 3 fed into the facing gap S as described above and the adhesive agent 2b of the tape agent piece 2A are maintained in a light contact state. , It is regulated to be transported without being separated from each other.

Note that FIG. 3 shows a state in which the liner 3 is horizontally transported on both the upstream side and the downstream side in the transport direction of the facing gap S in order to make the explanation easy to understand. The liner 3 located on the upstream side (left side in FIG. 3) in the transport direction of the gap S is wound around the raw material supply roll 1a from the diagonally lower side.

On the other hand, the liner support roll 1e at this time is rotationally driven at a constant speed as described above, but the raw material supply roll 1a arranged to face the upper side of the liner support roll 1e is intermittent. It is controlled so that it is driven to rotate, and the rotation operation and the stop operation are alternately repeated. That is, when the raw material supply roll 1a rotates, the continuous body of the tape agent piece 2A is conveyed as described above, but the rotation operation of the raw material supply roll 1a is stopped. Therefore, the tape agent piece 2A is maintained in a stopped state together with the raw material supply roll 1a without being conveyed.

In the intermittent supply operation of the tape agent piece 2A by the intermittent rotation operation of the raw material supply roll 1a, the tape agent pieces 2A arranged in a continuous state are supplied onto the liner 3 while being individually separated in the transport direction. It is done to do. More specifically, first, as shown in FIG. 3B, the tip edge of each tape agent piece 2A arranged in a continuous state in the transport direction is the lower top portion X of the raw material supply roll 1a. When the front position is reached, control is performed so that the raw material supply roll 1a is temporarily stopped. Each tape agent piece 2A in the stopped state is maintained in a state of being adsorbed on the outer peripheral surface of the raw material supply roll 1a by the suction force applied from the intake means described above, but the liner support roll. It is not yet in contact with the liner 3 on 1e.

Then, the stopped state of the raw material supply roll 1a is maintained until the liner 3 is conveyed by a predetermined distance (for example, 20 mm), after which the raw material supply roll 1a starts rotating again. Then, when the rotation operation of the raw material supply roll 1a is started, the transport of the continuous body of the tape agent piece 2A is restarted, whereby the tip portion of the tape agent piece 2A in the transport direction comes into contact with the liner 3 on the liner support roll 1e. Then, from that point on, the tape agent piece 2A starts to stick to the surface of the liner 3.

Further, at the position where the tape agent piece 2A starts to stick to the surface of the liner 3, more specifically, at the facing gap S formed in the lower apex portion X of the raw material supply roll 1a, the above-mentioned tape is used. The suction force of the intake means with respect to the agent piece 2A is set to be small so that the tape agent piece 2A can be easily removed from the raw material supply roll 1a as shown in FIG. 3C. It is in a state of being separated from each other. As a result, the tape agent piece 2A on the raw material supply roll 1a side that has reached the facing gap S described above is pressed against the liner 3 side in the portion between the facing gaps S and is in close contact with each other to be in a sticking state. Transfer from the material supply roll 1a to the liner 3 side is performed.

In this way, when the tape agent piece 2A conveyed by the rotational operation of the raw material supply roll 1a is brought into close contact with the liner 3 on the liner support roll 1e and transferred, the tape agent piece 2A and the tape agent piece 2A are transferred. Since the liner 3 and the liner 3 are conveyed at the same speed, the transfer operation of the tape agent piece 2A is stably performed.

On the other hand, the tape agent piece 2A transferred onto the liner 3 by the rotational operation of the raw material supply roll 1a is integrally transferred to the downstream side in the transport direction, and is transferred to the downstream side in the transport direction. As shown in the above, when the tip edge of the tape agent piece 2A'that has been conveyed next reaches the position in front of the lower apex X of the raw material supply roll 1a, the raw material supply roll 1a Is controlled so that it is stopped again.

At the time when this stop control is performed, the rear end portion (width dimension region of 3 mm to 4 mm in the transport direction) of the tape agent piece 2A that has already been transferred onto the liner 3 remains on the raw material supply roll 1a side. However, the suction force of the tape agent piece 2A to the rear end portion of the tape agent piece 2A is controlled to be small as described above, and the liner support roll 1e and the raw material supply roll 1a are combined. Since the tape agent piece 2A and the liner 3 carried into the inside of the facing gap S formed between them are maintained in a light contact state in which they do not separate from each other, the rear end portion of the tape agent piece 2A Is in a state of being easily separated from the raw material supply roll 1a.

On the other hand, in the tape agent piece 2A at that time, most of the region except the rear end portion has already moved to the liner 3 side and is in a sticking state, and the tape agent piece 2A is attached to the liner 3. It sticks with a sufficiently large adsorption force. Therefore, as the liner 3 is steadily conveyed, the tape agent piece 2A is also steadily conveyed, and the total length including the rear end portion of the tape agent piece 2A is on the raw material supply roll 1a side. Stable transfer from to the liner 3 side.

Then, as shown in FIG. 3 (e), the rear end portion of the tape agent piece 2A described above is a predetermined distance from the lower apex portion X of the raw material supply roll 1a due to the steady transfer of the liner 3. For example, the rotation of the raw material supply roll 1a is restarted at the timing when only 20 mm is conveyed and separated to the downstream side. As a result, the next tape agent piece 2A'is supplied onto the liner 3 from the tip side thereof and is transferred to the liner 3, and as shown in FIG. 2C, the tip of the next tape agent piece 2A'is transferred. The portions are conveyed at a predetermined interval, for example, 20 mm from the rear end portion of the tape agent piece 2A. Hereinafter, by repeating the same operation, as shown in FIG. 2 (d), the tape agent pieces 2A, 2A, ... With a predetermined interval, for example, 20 mm, being individually spaced on the liner 3.・ ・ Is in a parallel state.

[About the transport operation control unit]
Next, each part of the adhesive tape agent manufacturing apparatus including the cutting / bonding unit 1 as described above is based on a command signal output from a transport operation control unit (control) as shown in FIG. 4, for example. Operation is controlled. The transport operation control unit in the present embodiment is generally adhesive to a ROM 101 that stores various control programs required for the transport control operation, a volatile memory 102 and a non-volatile memory 103 that store various data related to the transport control operation. It includes various sensors and encoders that monitor the state of each part of the tape agent manufacturing device, and a CPU (central processing unit) 104 that controls the operation of the entire transfer operation control unit by executing various control programs.

The CPU 104 described above is bus-connected to various actuators 106 including a drive motor involved in a transfer control operation via a predetermined interface (I / O) 105. Then, while the conditions related to the transfer control operation of each part are set from the control panel, the transfer operation signal transferred from the network connecting various external devices is transferred, and the predetermined transfer operation is executed. There is.

According to the adhesive tape agent manufacturing apparatus having such a configuration, when the tape agent piece 2A is supplied from the raw material supply roll 1a side to the liner 3 side by the rotational operation of the raw material supply roll 1a, the tape agent piece 2A is subsequently supplied. When the rotation of the raw material supply roll 1a is stopped, the supply operation of the tape agent piece 2A from the raw material supply roll 1a to the liner 3 side is temporarily stopped, and the supply operation of the tape agent piece 2A is stopped. Over the movement distance of the liner 3, the transfer operation is performed with a certain distance between the tape agent piece 2A'and the tape agent piece 2A'to be supplied next. When the tape agent piece 2A is transferred to the liner 3 side, the raw material supply roll 1a and the liner support roll 1e are rotated at substantially the same peripheral speed, so that the liner 3 and the tape agent piece 2A have substantially the same speed. The behavior when the tape agent piece 2A is transferred is stabilized, and the conventional air pools and air bubbles are not formed between the liner 3 and the tape agent piece 2A.

Further, according to the adhesive tape agent manufacturing apparatus having such a configuration, when the tape agent piece 2A is transferred, the tape agent piece is formed at a portion facing the raw material supply roll 1a and the liner support roll 1e. Since the 2A and the liner 3 are maintained in a light contact state in which they do not separate from each other, air accumulation and air bubbles between the tape agent piece 2A are reduced, and at the same time, the raw material supply roll 1a and the liner support are supported. By keeping the adhesive agent 2b in a state where it is not pressed by the roll 1e, the adhesive agent 2b does not "protrude" toward the outside of the tape agent piece 2A, and the tape base material 2a No "wrinkles" are generated at the rear end portion in the transport direction.

The invention made by the present inventor has been specifically described above based on the embodiment, but the present embodiment is not limited to the above-described embodiment, and various modifications can be made without departing from the gist thereof. Needless to say.

For example, in the above-described embodiment, a partially polymerized liner is used, but the present invention also applies to the case where a single liner is used or a so-called back-split liner is used. Can be applied.

As described above, the present invention can be widely applied to a wide variety of manufacturing apparatus for adhesive tapes.
