Description

Leading film winding device {LEADING FILM WINDING DEVICE}

The present invention relates to a leading film winding device that can automatically perform a series of operations of attaching, winding, and finishing a leading film to an empty roll.

Roll-to-roll processes are currently being implemented in various industrial fields. In the roll-to-roll process, the fabric is unwound from the unwinding roll and wound around the winding roll. In this process, the fabric moves from the unwinding roll to the winding roll, and the necessary processes are applied to the fabric as it moves.

The old fabric being used wound on the unwinding roll is usually connected to the new fabric wound on the new unwinding roll when its exhaustion is imminent. In this case, after the old fabric is cut, the cut end of the old fabric and the new fabric are bonded. Connected with tape, etc. In addition, the remaining section of the old fabric that is still wound on the unwinding roll after the cutting is discarded. In order to minimize the remaining section discarded, a leading film is first wound on an empty unwinding roll, and then the fabric is connected to this leading film and wound. The method is known.

The winding roll on which the fabric is wound in the roll-to-roll process may also be used by winding a leading film on an empty winding roll, because if a subsequent roll-to-roll process is required for the fabric wound on the winding roll, the winding roll is used in this subsequent roll-to-roll process. This is because it is used as an unwinding roll.

Meanwhile, the leading film is also called a connecting film, a lead film, etc.

Publication of Patent No. 10-2017-0102350 (Method of manufacturing reel body, film connector, film winding mount, and film connector) Publication of Patent No. 10-2019-0035956 (Method of manufacturing reel body, film connector, film winding mount, and film connector) Registered Patent Publication No. 10-2381970 (Connecting film auxiliary device for core) Publication of Patent No. 10-2023-0122541 (Film winding device for electrode connection, winding method, and electrode roll)

In order to use the leading film, there are three steps: connecting one end of the leading film to an empty roll, winding the leading film on an empty roll, and attaching a double-sided tape for connecting the fabric to the opposite end of the leading film wound on the empty roll. It is necessary to finish the opposite end of the lidding film with double-sided tape attached.

Accordingly, the present invention seeks to provide a leading film winding device that can automatically perform the above operations.

The present invention is a forward operation of unwinding the leading film fabric from a leading film fabric winding roll coupled to a frame forming the overall frame and advancing it to an empty roll coupled to the frame, and the front end of the advancing leading film fabric and the outer surface of the empty roll. A single-sided tape adhesion operation of adhering a single-sided tape, continues moving forward after the single-sided tape adhesion operation, stops the leading film fabric wound on the empty roll, and then cuts it to separate the leading film fabric from the front portion extending from the empty roll and the leading film fabric winding roll. A cutting operation to separate the extending rear portion, a double-sided tape adhesion operation to attach a double-sided tape to the cut end of the front portion after the cutting operation, and a double-sided tape adhesion operation to attach a portion of the dog bone tape to the double-sided tape. It is a leading film winding device that automatically performs dog bone tape adhesion. Here, the one-sided tape is adsorbed to a suction roll coupled to the frame adjacent to the empty roll with its adhesive side facing outward. In the single-sided tape adhesion operation, the suction roll and the empty roll begin to rotate opposite to each other before the front end of the advancing leading film fabric reaches the empty roll, and then the suction roll and the empty roll with their suction force released. The roll passes the single-sided tape while pressing it, and then passes the front end of the overlapping single-sided tape and the leading film fabric while pressing it.

In the single-sided tape adhesion operation, rotation of the suction roll and the empty roll begins when a sensor fixed to the frame detects an identifier formed on the surface of the lidding film fabric. The surface of the suction roll is made of a release material.

In the forward operation, the leading film fabric moves forward while maintaining a downward inclined posture so that the front end of the leading film fabric automatically reaches the outer surface of the empty roll.

The forward operation is performed by a forward roll coupled to the frame so as to be located in front of the leading film fabric winding roll. And the downwardly inclined posture of the leading film fabric is coupled to the frame such that the empty roll is positioned lower than the forward roll in front of the forward roll, and the frame is in the downwardly inclined posture between the forward roll and the empty roll. The support block coupled to is maintained by supporting the leading film fabric.

During the forward operation, the support block discharges air toward the leading film fabric with a pressure sufficient to reduce friction between the leading film fabric and the support block.

In the cutting operation, the leading film fabric is stopped by stopping the forward roll, empty roll, and suction roll, and then the leading film fabric is adsorbed to the support block and then cut by a cutting means coupled to the frame. It is divided into the anterior region and the posterior region.

The support block includes a front support block and a rear support block located adjacent to each other with a gap in between, and the cutting means is located below the support block to cut the portion of the lidding film fabric located in the gap. It is prepared.

In the cutting operation, the cut end of the rear portion is retracted, but this retraction is made to the extent that the dog bone tape is not adhered to the cut end of the rear portion in the dog bone tape adhesion operation.

In the cutting operation, the forward roll, empty roll, and suction roll are stopped when the amount of advancement of the leading film fabric from the time the forward operation begins reaches a predetermined standard amount.

A double-sided tape adhesive means for performing the double-sided tape adhesive operation and a dog bone tape adhesive means for performing the dog bone tape adhesive operation are movably coupled to the frame.

The dog bone tape adhesive means includes a pair of dog bone fabric rolls spaced apart from each other and coupled to the moving frame; A dog bone fabric that moves in the width direction of the leading film fabric when unwound from one of the pair of dog bone fabric rolls and wound around the other. and a pick-up member coupled to the moving frame and provided to sequentially pick up the dog-bone tapes of the dog-bone fabric and adhere a portion of the picked-up dog-bone tape to the double-sided tape.

According to the present invention, the task of attaching a single-sided tape is simply performed by a suction roll adsorbing the single-sided tape.

According to the present invention, the start point of the single-sided tape adhesion operation and the start point of the cutting operation can be automatically detected.

According to the present invention, since the leading film fabric advances in a downwardly inclined position so that the front end of the leading film fabric automatically reaches the outer surface of the empty roll, a separate pull is required to grip the front end of the leading film fabric and pull it to the empty roll. No means are required.

According to the present invention, because air is discharged to the leading film fabric moving forward in a downward inclined posture, the forward movement of the leading film fabric is smooth.

According to the present invention, the leading film fabric can be cut while being firmly fixed to the support block.

According to the present invention, there is no room for the cutting means to interfere with the movement of the double-sided tape adhesive means and the dog bone tape adhesive means.

According to the present invention, the phenomenon of dogbone tape adhering to both parts of the leading film fabric located on both sides of the cutting line is definitely prevented.

Hereinafter, preferred embodiments of the lidding film winding device according to the present invention will be described in detail with reference to the drawings. The terms or words used below should not be construed limited to their usual or dictionary meanings, and based on the principle that an inventor can appropriately define the concept of a term in order to explain his or her invention in the best way, It should be interpreted with meaning and concept consistent with the technical idea of the present invention.

As shown in FIG. 1, the leading film winding device 1000 according to the present invention includes a leading film fabric winding roll 200 coupled to a frame (not shown) forming the overall frame, an empty roll 210, and a forward roll. It includes (300) and a support block (400).

The leading film fabric 20 is wound on the leading film fabric winding roll 200, the forward roll 300 is located in front of the leading film fabric winding roll 200, and the empty roll 210 is located on the forward roll 300. ) is located lower than the forward roll 300 in front. The support block 400 is located between the forward roll 300 and the empty roll 210, and assumes a downward sloping posture as it moves forward.

As shown in FIG. 1, the forward roll 300 includes a driving roll 310 around which the leading film fabric 20 is wound and a pinch roll 320 that presses the leading film fabric 20 to the driving roll 310. It can be configured. The drive roll 310 rotates by a motor, and the pinch roll 320 is an idle roll. When the driving roll 310 rotates forward by the motor, the leading film fabric 20 is unwound from the leading film fabric winding roll 200 and moves forward. Conversely, when the driving roll 310 rotates backward by the motor, the leading film fabric 20 moves forward. (20) moves backwards. The forward roll 300 may be composed of only the drive roll 310 without the pinch roll 320. In this case, the drive roll 310 is composed of a suction roll.

Initially, as shown in FIG. 1, the front end of the leading film fabric 20 is unwound from the leading film fabric winding roll 200, passes through the forward roll 300, and is supported by the rear end of the support block 400. When the forward roll 300 operates in this state, a forward operation in which the leading film fabric 20 advances to the empty roll 210 is performed. During this forward operation, the leading film fabric 20 is supported by the support block 400 and advances in the downward inclined posture, and the front end of the leading film fabric 20 automatically reaches the outer surface of the empty roll 210. do.

If the leading film fabric 20 advances horizontally in the forward operation, the front end of the leading film fabric 20 must be pulled by a separate traction means to reach the empty roll 210, because the leading film fabric (210) This is because 20) is very thin and is bent downward by gravity between the support block 400 and the empty roll 210. However, in the present invention, as seen above, during the forward operation, the leading film fabric 20 advances in a downwardly inclined position so that the front end of the leading film fabric 20 automatically reaches the outer surface of the empty roll 210, so that the separate No towing means is required.

Meanwhile, because the leading film fabric 20 is very thin, there is a risk that it may not advance smoothly on the support block 400 even when the forward roll 300 operates. Therefore, the support block 400 may discharge air at a weak pressure toward the leading film fabric 20 during the forward operation. In this case, friction between the leading film fabric 20 and the support block 400 is reduced, so that the leading film fabric 20 can move forward smoothly.

As shown in FIG. 1, the leading film winding device 1000 also includes a suction roll 600 coupled to the frame so as to be positioned adjacent to the empty roll 210. This suction roll 600 has a partial area as an adsorption area, and the one-sided tape 30 is adsorbed to this adsorption area with its adhesive surface facing outward.

While the forward operation is being performed in the initial state of FIG. 1, when the sensor 800 installed on the frame detects the identifier (not shown) previously formed on the surface of the leading film fabric 20, as shown in FIG. 2, the single-sided tape adhesion operation is performed. This begins. The point at which the sensor 800 detects the identifier is before the front end of the leading film fabric 20 reaches the empty roll 210, as shown in FIG. 2.

In the single-sided tape adhesion operation, the moment the sensor 800 detects the identifier, the empty roll 210 begins to rotate by the motor, and the suction roll 600 also begins to rotate in the opposite direction to the empty roll 210 by the motor. Afterwards, as shown in FIG. 3, a portion of the one-sided tape 30 is sandwiched between the suction roll 600 and the empty roll 210 and is adhered to the empty roll 210. From this point on, the suction roll 600 The adsorption force is released. Immediately after that, the remaining portion of the single-sided tape 30 and the front end of the leading film fabric 20 overlap each other and are sandwiched between the suction roll 600 and the empty roll 210, and at this time, the remaining portion of the single-sided tape 30 The portion is adhered to the front end of the lidding film fabric 20. If the support block 400 is discharging low-pressure air as seen above, this discharging stops at the point when adhesion of the one-sided tape 30 is completed.

The leading film winding device 1000 also includes a cutting means 500 as shown in FIG. 1 . The cutting means 500 may include a blade 510 and a cylinder 520. The blade 510 reciprocates toward or away from the leading film fabric 20 when the cylinder 520 operates. And the cylinder 520 is coupled to the frame so that it can reciprocate in the width direction of the leading film fabric 20.

As will be described later, on the upper part of the leading film fabric 20, the double-sided tape adhesive means 100 and the dog bone tape adhesive means 700 move, and the cutting means 500 moves on the double-sided tape adhesive means 100 and the dog bone tape adhesive means 700. It is better to place it at the lower part of the leading film fabric 20 so as not to interfere with the movement of the tape adhesive means 700. In this case, the support block 400 is composed of a front support block 410 and a rear support block 420 positioned apart from each other with a gap through which the blade 510 comes out.

Even after the single-sided tape adhesion operation seen above, the operation of the suction roll 600, the empty roll 210, and the forward roll 300 are maintained, and as a result, the leading film fabric 20 continues to advance at a constant tension and the empty roll 210 ) is wound on. Then, when the amount of advancement of the leading film fabric 20 reaches a predetermined standard amount, the cutting operation begins. At this time, the amount of advancement of the leading film fabric 20 can be calculated using an encoder (not shown) that detects the rotation amount of the pinch roll 320.

In the cutting operation, the operation of the suction roll 600, empty roll 210, and forward roll 300 first stops, and as a result, the leading film fabric 20 that was moving forward also stops. Afterwards, first, the front support block 410 and the rear support block 420 adsorb the lidding film fabric 20. Next, the blade 510 is raised by the cylinder 520 and the cylinder 520 moves in the width direction of the leading film fabric 20. Then, the leading film fabric 20 moves along the gap (a blade ( 510) and is separated into a front portion 20 extending from the empty roll 210 and a rear portion 20 extending from the leading film fabric winding roll 200. Next, due to the reverse operation of the forward roll 300, the cut end (front end) of the rear portion 20 moves backward slightly to the state shown in FIG. 4, and thus the cutting operation is completed. Here, the reason for slightly retracting the cut end of the rear portion 20 is to prevent the dog bone tape 40 from adhering to the cut end of the rear portion 20.

Meanwhile, instead of reverse operation of the forward roll 300, the cut end (front end) of the rear portion 20 may be slightly advanced by reversing the rear support block 420. In this case, the rear support block 420 will be movably coupled to the frame.

As shown in FIG. 1, the leading film winding device 1000 also includes a double-sided tape adhesive means 100 and a dog bone tape adhesive device 700. The double-sided tape adhesive means 100 and the dog bone tape adhesive means 700 are coupled to a moving frame (not shown) movably coupled to the frame and move simultaneously.

When the cutting operation described above is completed, the moving frame moves so that the double-sided tape adhesive means 100 approaches the cut end (rear end) of the front portion 20, as shown in FIG. 5. And in this state, the double-sided tape adhering means 100 performs a double-sided tape adhesion operation of adhering the double-sided tape 12 to the cut end of the front portion 20. When the double-sided tape adhesion work is completed, the moving frame is moved so that the dog bone tape adhesion means 700 approaches the cut end of the front portion 20, as shown in FIG. 6. And in this state, the dogbone tape adhesion means 700 performs a dogbone tape adhesion operation of adhering a portion of the dogbone tape 40 to the double-sided tape 12. After all of these double-sided tape adhesion operations and dog bone tape adhesion operations are completed, the cut end of the front portion 20 appears as shown in FIG. 7.

After the dog bone tape adhesion work is completed (state of FIG. 6), the suction roll 600 and the empty roll 210 rotate again. And while this rotation is taking place, the front portion 20 moves forward and is completely wound around the empty roll 210, and the dog bone tape 40 is caught between the suction roll 600 and the empty roll 210 when passing. It is attached to the already wound front portion 20 to prevent the cut end of the front portion 20 from unraveling.

Here, the double-sided tape 12 attached to the contact end of the front portion 20 is also sandwiched between the suction roll 600 and the empty roll 210 and passes through, and the surface of the suction roll 600 is covered with a double-sided tape ( 12) It is preferable that it is made of a release material that does not stick well (e.g., silicone, Teflon, etc.). And the adsorption force of the front support block 410 is released when the front portion 20 leaves the front support block 410. The adsorption force of the rear support block 410 may be released when the adsorption force of the front support block 410 is released, or may be released when the forward operation is performed again on the rear portion 20.

Meanwhile, in order to rewind the lidding film fabric 20 on the new empty roll 210, replace the empty roll 210 on which the front part 20 is wound with a new empty roll 210 and attach it to the suction roll 600. After adsorbing the new single-sided tape (30), repeat the above operations. At this time, the operation of adsorbing the new single-sided tape 30 to the suction roll 600 can be performed automatically by a single-sided tape supply means (not shown) installed on the frame. Additionally, the automatic adhesive tape supply device disclosed in Patent Registration No. 10-2599538 may be used as the single-sided tape supply means.

The empty roll 210 on which the front portion 20 of the leading film fabric 20 is wound can be used as a winding roll in the roll-to-roll process. In addition, the roll that is further wound around the empty roll 210 after attaching the process fabric required for the roll-to-roll process to the double-sided tape 12 can be used as an unwinding roll in the roll-to-roll process.

Meanwhile, the dog bone tape adhesive means 700 will be described with reference to FIG. 7 as follows.

The dog bone tape adhesive means 700 includes a pair of dog bone fabric rolls 710 and 720 coupled to the moving frame so as to be spaced apart in the width direction of the leading film fabric 20. The first fabric roll 710, one of the two dog bone fabric rolls 710 and 720, is wound around the dog bone fabrics 730 and 40. The dog bone fabrics 730 and 40 are prepared in a form in which dog bone tapes 40 are attached to a release paper 730 in a row. The second fabric roll 720, which is the remaining one of the two dog bone fabric rolls 710 and 720, winds the release paper 730 when rotated by a motor.

The dog bone tape adhesive means 700 also includes a pickup member 740. The pickup member 740 is coupled to the moving frame to enable up and down lifting and reciprocation in the width direction, and is provided to adsorb the dog bone tape 40 of the dog bone fabrics 730 and 40. This pickup member 740 adsorbs the dog bone tapes 40 attached to the release paper 730 one by one, and then attaches about half of the adsorbed dog bone tapes 40 to the double-sided tape 12 of the leading film fabric 20. ) is attached.

The double-sided tape adhesive means 100 will be described with reference to FIGS. 8 to 11 as follows. However, although the leading film fabric 20 is shown in FIGS. 8 to 11 as being much thicker than the double-sided tape 12, it should be noted in advance that in reality, the thicknesses of the two members 12 and 20 are similar.

The double-sided tape adhesive means 100 includes a fabric roll 110 coupled to the moving frame, a guide roll 120, an attachment roll 130, a recovery roll 140, and a cutter 150.

Double-sided tape fabric 10 is wound on the fabric roll 110. The double-sided tape fabric 10 is composed of a double-sided tape 12 and a release paper 14, and the release paper 14 covers one of the two adhesive layers of the double-sided tape 12. When the double-sided tape fabric 10 is wound on the fabric roll 110, the release paper 14 is located on the outside of the double-sided tape 12. The double-sided tape fabric 10 wound on the fabric roll 110 is moved when the moving frame moves first and second in the width direction of the leading film fabric 20 (movement from right to left in FIG. 8). As it is released from (110), the fabric roll (110) rotates.

The double-sided tape fabric 10, which is unwound from the fabric roll 110 during the first and second movements of the moving frame, passes through the guide roll 120 and rotates the guide roll 120. When the double-sided tape fabric 10 passes through the guide roll 120, the double-sided tape 12 is located outside the release paper 14.

During the first and second movements of the moving frame, the double-sided tape fabric 10 passes through the guide roll 120 and reaches the attachment roll 130, and then is attached to the leading film fabric 20 by the attachment roll 130. is pressed toward the cut end of the. Then, the release paper 14 of the pressurized double-sided tape fabric 10 moves toward the recovery roll 140 and rotates the attachment roll 130, and the double-sided tape 12 of the pressurized double-sided tape fabric 10 moves toward the leading film fabric. It is attached to the cut end of (20), and as a result, the double-sided tape fabric 10 is separated into the double-sided tape 12 and the release paper 14 on the attachment roll 130.

The recovery roll 140 consists of a drive roll that rotates by a motor installed on the moving frame. During the first and second movement of the frame, the recovery roll 140 is rotated by a motor, and as a result, the release paper 14 that has passed through the attachment roll 130 is wound around the recovery roll 140 and recovered.

The cutter 150 cuts only the double-sided tape 12 of the double-sided tape fabric 10 that is in contact with the guide roll 120 in a state in which the moving frame is temporarily stopped after the first movement (state of FIG. 9). It is for. This cutter 150 will be described in detail with reference to FIG. 11 as follows.

The cutter 150 is coupled to the reciprocating block 152 installed on the moving frame so that it can reciprocate along the longitudinal direction of the leading film fabric 20. Accordingly, the cutter 150 moves in the longitudinal direction of the leading film fabric 20 together with the reciprocating block 152. In addition, the cutter 150 is coupled to the reciprocating block 152 so that it can rotate around the rotation axis 151, and is also coupled to the cylinder rod of the cylinder 153 fixed to the reciprocating block 152. Accordingly, the cutter 150 rotates from the cutting position to the non-cutting position when the cylinder 153 extends the cylinder rod, and rotates from the non-cutting position to the cutting position when the cylinder 153 retracts the cylinder rod.

At the cutting position, the blade tip of the cutter 150 only reaches the boundary between the double-sided tape 12 and the release paper 14 of the double-sided tape fabric 10 in contact with the guide roll 120, as shown in FIG. 11, In this state, when the reciprocating block 152 moves, only the double-sided tape 12 of the double-sided tape fabric 10 in contact with the guide roll 120 is cut, but the release paper 14 is not cut. In addition, at the cutting position, the blade tip of the cutter 150 is inclined at an angle with respect to the double-sided tape 12 of the double-sided tape fabric 10 in contact with the guide roll 120, as shown in FIG. 11. Then, the cutter 150 Compared to the case where the blade end of (150) is perpendicular to the double-sided tape (12), only the double-sided tape (12) can be cut more reliably. Meanwhile, in the non-cutting position, the blade tip of the cutter 150 is separated from the double-sided tape 12, as shown in FIGS. 8 and 10.

A stopper 155 for a cutting position may be further fixed to the reciprocating block 152. At this time, the stopper 155 for the cutting position is provided to prevent the rotation of the cutter 150 when it reaches the cutting position. That is, the cutter 150 rotating from the non-cutting position to the cutting position is caught by the cutting position stopper 155 at the cutting position and cannot rotate any more. Therefore, if the stopper 155 for the cutting position is provided, it is possible to completely prevent an unintended accident in which the cutter 150 cuts not only the double-sided tape 12 but also the release paper 14. Meanwhile, a stopper 156 for a non-cutting position may be further installed in the reciprocating block 152 to prevent rotation of the cutter 150 that has reached the non-cutting position.

A weight 154 may be installed on the cutter 150. In this case, the weight 154 is installed on the cutter 150 so as to be located on the opposite side of the blade end of the cutter 150 based on the rotation axis 151, and is provided to rotate the cutter 150 from the non-cutting position to the cutting position. do. When such a weight 154 is provided, firstly, the self-weight of the weight 154 offsets the self-weight of the cutter 150, so there is an advantage that an ultra-small cylinder can be used as the cylinder 153, and secondly, the double-sided tape (12) ) has the advantage of being uniform across the entire width of the double-sided tape (12).

A pressure roll 160 may be further installed on the moving frame. In this case, the pressure roll 160 presses the double-sided tape 12 attached to the cut end of the leading film fabric 20 by the attachment roll 130, making attachment more secure. Meanwhile, since this pressure roll 160 comes into contact with the adhesive layer of the double-sided tape 12, the surface material is made of silicone, Teflon, etc., which do not stick to the adhesive layer. In some cases, pressurization of the double-sided tape 12 by the pressure roll 160 may not be required, and the pressure roll 160 may be configured to rotate around the rotation axis 162 when the cylinder 164 operates. there is. At this time, the rotation shaft 162 and the cylinder 164 are installed on the moving frame.

Hereinafter, the operation process of the double-sided tape adhesive means 100 will be described.

First, with the moving frame raised, the worker unwinds the double-sided tape fabric 10 from the fabric roll 110, passes it through the guide roll 120 and the attachment roll 130, and then unwraps the release paper 14 of the double-sided tape fabric 10. is fixed and wound on the recovery roll 140. At this time, the end of the double-sided tape 12 of the double-sided tape fabric 10 is located at the 6 o'clock direction of the attachment roll 130, as shown in FIG. 8.

When the double-sided tape adhesion work begins in this initial state, the moving frame descends from the most advanced position, and then the attachment roll 130 presses the double-sided tape fabric 10 toward the cut end of the leading film fabric 20, as shown in Figure 8. do.

Afterwards, the frame first moves left to a predetermined position as shown in FIG. 9, and at the same time, the recovery roll 140 is rotated by a motor. During this process, the double-sided tape 12 is continuously attached to the cut end along the width direction of the leading film fabric 20, and the release paper 14 is attached to the cut end from the double-sided tape 12. As it is separated and wound on the recovery roll 140, the fabric roll 110, guide roll 120, and attachment roll 130 rotate, and the pressure roll 160 rolls after the attachment roll 130 to attach the double-sided tape (12). ) is further pressed toward the cut end.

After the first movement, the moving frame and recovery roll 140 are temporarily stopped. And when the temporary stop is made, the cutter 150 rotates to the cutting position by the cylinder 153 and then the reciprocating block 152 moves, and then the double-sided tape fabric 10 in contact with the guide roll 120 Only the double-sided tape 12 is cut.

When the cutting of the double-sided tape 12 is completed, the moving frame moves to a predetermined position as shown in Figure 10, and at the same time, the recovery roll 140 is rotated again by the motor. And while this process is taking place, the double-sided tape 12 is attached to the left end of the cut end of the leading film fabric 20, and the release paper 14 is wound on the recovery roll 140 and the fabric roll 110 and the guide roll ( 120) and the attachment roll 130 are rotated, and the pressure roll 160 rolls after the attachment roll 130 to further press the double-sided tape 12 toward the cut end. When this secondary movement is completed, the cutting line C formed by the cutter 150 is located at the 6 o'clock direction of the attachment roll 130, as shown in the enlarged view of FIG. 10.

After the second movement, the moving frame continuously moves further to a predetermined position without stopping. At this time, the motor stops and the recovery roll 140 does not rotate, and the brake is applied to the fabric roll 110, so the fabric roll 110 does not rotate, and as a result, the guide roll 120 and the attachment roll 130 also do not rotate. If the attachment roll 130 continues to rotate even during the additional movement, an unintended problem occurs in which the double-sided tape 12 on the left side of the cutting line C is also attached to the cut end. This problem is solved in the present invention. Do not rotate the attachment roll (130) when moving additionally to prevent damage.

After the additional leftward movement is completed, the moving frame rises and then moves rightward to the rightmost position and waits, thereby completing the double-sided tape adhesion work.

As described above, although the present invention has been described with limited examples and drawings, the present invention is not limited thereto, and the technical idea of the present invention and the following will be understood by those skilled in the art to which the present invention pertains. Of course, various modifications and variations can be made within the scope of equivalency of the claims to be described, and the above-described embodiments can be combined in various ways.
