DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig for sticking an adhesive tape, and more particularly, to folding and sticking an adhesive tape having an adhesive layer on one side thereof according to the shape of an adherend. It relates to a sticking jig for performing. The sticking jig according to the present invention does not select the shape of the adherend to which the adhesive tape is to be attached, and therefore can adhere the adhesive tape to adherends having various different shapes.
For example, the sticking jig of the present invention can be used for folding and sticking an adhesive tape to a deformed adherend having a substantially uniform cross section. Here, the "irregular shape" means that the cross-sectional shape of the tape affixed portion of the adherend is not flat, that is,
It has a shape such as T-shaped, chevron, triangular, trapezoidal, rectangular, and horseshoe-shaped. The folding sticking jig of the present invention includes, for example, vehicles such as automobiles, ships, vehicles such as aircraft, buildings, and the sticking of an adhesive tape used for interior or exterior of other structures, such as stripes, It can be advantageously used for sticking work of marks, stickers, emblems and the like.

[0002]

2. Description of the Related Art Conventionally, when an adhesive tape such as a sticker or an emblem is adhered to an adherend, it is generally performed manually and, if necessary, an auxiliary tool such as a squeegee is used. It is. In other words, in the conventional method, an adhesive tape is manually crimped to a predetermined portion of an adherend while paying attention so that wrinkles do not occur and air biting does not occur. When squeegees occur, a squeegee or the like is pressed against the squeegee to move the inflated portion to remove air from between the adherend and the adhesive tape. Next, the adhesive tape is gradually bent so that the folded surface of the adherend is involved. This bending work,
Using a squeegee or the like, carefully take care over time, taking care not to cause wrinkles or air bites. Thus, in the conventional method, it takes time, time, and
Importantly, skill is required, and attention must be paid to the occurrence of wrinkles and air bites.

[0003] The disadvantages of the conventional methods as described above are, in particular,
This is remarkable when the adherend is a long object. That is,
In such a case, it is necessary to repeat the complicated and problematic steps as described above, and the problem that wrinkles are likely to occur and air easily enters occurs more frequently. This is because it largely depends on the skill level, and the working time also increases in proportion to the length of the long object.

[0004] In order to solve the problems of the conventional method, and to make it possible to apply an adhesive tape of one shape accurately and promptly to application parts of various shapes,
The present inventor has invented an adhesive tape sticking device as disclosed in, for example, JP-A-5-338627. As shown in a perspective view in FIG. 1, the adhesive tape sticking device 30 includes a handle 31, a tape slide 32, a tension pole 33, a guide member 34, a sticking head 35, and a handle 31 and a tape slide 32. Support wall 3 to support
6 is provided. The tension pole 33 can apply a predetermined tension to the adhesive tape during the attaching operation. In addition, the guide member 34 holds the adherend (not shown) from both sides during the attaching operation, thereby enabling the attaching device 30 to follow the elongated shape of the adherend. The application head 35 has an application surface 37 having a finished surface 37a substantially equal to the surface shape of the tape application site. Although this adhesive tape applying apparatus can produce the remarkable effects as described above, after performing the operation of applying the adhesive tape,
Squeegee and Japanese Patent Laid-Open No. 9-132, which will be specifically described below.
It is necessary to perform a final finish using a sticking jig having a folding function described in Japanese Patent Publication No. 218. However, such work involves a number of steps such as positioning, sticking, folding, and winding the tape by the adhesive tape sticking apparatus itself, and these steps must be performed manually, which is very complicated. ,
In addition, it largely depends on the skill of the worker, and the working time is prolonged in proportion to the length of the long object to be adhered.

An attaching jig having a folding function described in JP-A-9-132218 has a structure shown in a perspective view in FIG. The folding attachment jig 40 has a jig body 42 made of an L-shaped plastic thin plate.
As shown, guide forming means 46 capable of forming a guide space 43 by deformation is provided on the inner wall of the jig body 42.

It is glued only to the two vertical inner walls.
The illustrated guide forming means 46 comprises a buffer layer 44 made of polyurethane foam and a surface sliding layer 45 made of leather.
It is composed of The guide space 43 in the folding and attaching jig 40 can be formed by a pressing means (here, a metal pin) 47. At the time of release of the metal pin 47, the metal pin 47 is housed in the hole of the main body 42 and does not contact the guide forming means 46. Then, metal pin 4
When the guide 7 is moved downward and the guide forming means 46 which has been in contact with the main body 42 is pushed downward, a stopper (not shown) works and the metal pin 47 is fixed. When the folding and attaching jig 40 is used, when the adhesive tape is folded and affixed to the adherend, the adhesive tape can be affixed to various adherends using the same jig. A remarkable effect that air biting is less likely to occur, and even non-technical workers can easily and easily perform the sticking work, and have good workability and easy handling, and can reduce work time. Can be obtained. But,
Even with such an improved attaching jig, it is essential to prepare a plurality of jigs, squeegees, and the like in order to completely cope with a wide variety of adherends.

[0006]

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION As described above, a jig for applying an adhesive tape according to the present invention comprises a tape crimping portion having a specific structure, a tape folding portion having a specific structure, and a tape winding portion having a specific structure in this order. It is characterized in that it is mounted on a common support frame so that the respective means function in cooperation when applying the adhesive tape.

In the jig for attaching an adhesive tape according to the present invention,
The common support frame and, if necessary, the auxiliary member formed integrally with the support frame or attached thereto by a suitable fixing member, etc., can be made of any material, of any shape and size convenient for handling. Can be formed. The size and shape of the support frame preferably correspond to the tape application site of the adherend to which the adhesive tape is to be applied. That is, the support frame is
Considering the workability and handleability of the jig, it is desirable that the jig is suitable for it. Suitable materials for the support frame, a metal material such as iron, aluminum or its alloys, plastic materials, such as polypropylene resin, polyethylene resin, polyacetal resin, ABS resin, nylon resin, fluorine-containing resins, particularly Teflon ^TM resin (Teflon Other trademark, etc.), acrylic resin, and the like. Among these materials,
Particularly suitable materials are those that are light in weight so that they do not bear the weight of long-term work. In addition, the support frame may be configured to be usable as a gripper in order to facilitate handling. Otherwise, a gripper such as a handle or a handle may be separately attached. Further, when it is expected that the sticking jig of the present invention is used in a cold region or in a low temperature condition, a heating means such as a built-in heater may be attached to the jig body or other appropriate places.

[0010] In the sticking jig of the present invention, the first component is a tape crimping portion provided with a tape sticking head for positioning an adhesive tape at a tape sticking portion of an adherend and crimping it. Can be composed of a support frame, a tape attaching head attached to the support frame for pressing the adhesive tape on the surface of the adherend, and a tape path constituting an approach path and a guide path of the adhesive tape. The tape path can be appropriately configured for introducing and guiding the adhesive tape and, if necessary, discharging the release paper of the adhesive tape, by an arbitrary combination of a member constituting the tape application head and the support frame. In particular, the tape application head, as used in the application jig invented by the present inventors, sequentially presses the adhesive tape against the tape application site of the adherend, preferably while gradually increasing the pressing force. In order to finally enable the adhesive tape to be adhered to the tape application portion, it is preferable that the surface portion is made of an elastic material. Suitable elastic materials include, for example, natural and synthetic rubbers, foamed plastic materials, such as foamed polyurethane,
Examples include various felt materials. The shape of the tape application head is not particularly limited, but is preferably a plate shape or a roller shape as specifically shown below. In the pressure-sensitive adhesive tape, the portion of the pressure-sensitive adhesive tape that is pressure-bonded to the adherend is usually a large portion of the pressure-sensitive adhesive tape. ".

[0011] In the sticking jig of the present invention, the second component is to fold the end face of the adhesive tape according to the tape sticking part when moving along the upper surface of the adhesive tape pressed by the tape pressing part. And a tape fold provided with a fold head that can be brought into contact with an adherend in the presence of an appropriate pressing force by an attached elastic member. As described above, the tape folded portion is an end surface of the adhesive tape that is not pressed to the tape attachment portion of the adherend in the previous tape attachment stage, in particular, both end surfaces (in the specification of the present application,
Various configurations can be adopted as long as the function of folding such a portion is particularly referred to as a “subordinate portion of the adhesive tape”.

Preferably, the tape folding portion includes an arm pivotally supported by a tip of a support leg attached to the support frame, and an elastic member attached to one end of the arm for rotating the arm. And the end of the arm to which the elastic member is not attached corresponds to a folding head, which comes into contact with the adherend in the presence of an appropriate pressing force, and the end surface of the adhesive tape is attached to the tape attaching portion. It can be folded to fit. Further, such a configuration may be a pair of structures in which the adherend is sandwiched with respect to the tape affixed portion, as described in detail in the following examples, or it is desired to further enhance the tape folding effect. In this case, two or more pairs of the folding heads may be able to more effectively contact the adherend. Although the shape of the tape folding head is not particularly limited, it is preferable that the tape folding head is formed in a rod shape or a roller shape in order to sufficiently exert its effect.

Further, the folding head of the tape folding section has a buffer layer made of an elastic material, and a surface sliding layer which is provided on the buffer layer and which is to be brought into contact with the pressure-sensitive adhesive tape. Is preferred.
Since the buffer layer of the folding head is mainly used for improving the cushioning property of the folding head which is brought into contact with the adherend, elastic materials such as natural and synthetic rubbers,
It is preferable to be made of a foamed plastic material, for example, foamed polyurethane, various felt materials, and the like. The thickness of the buffer layer can be arbitrarily changed in a wide range, but is preferably 0.5 to 10 mm. If this buffer layer is thinner than 0.5 mm, the desired elasticity cannot be obtained, and if it is thicker than 10 mm, the contact effect of the folding head on the adherend cannot be obtained.

The surface sliding layer provided on the buffer layer is intended to assist the head to smoothly move over the tape-attached portion of the adherend, and is therefore a fluorine-containing resin, especially Teflon ^™ resin. , Nylon, natural and synthetic leather, other tapes, sheets, fabrics and the like. In particular, considering slipperiness and wear resistance,
The use of leather is more preferred. Although the thickness of the surface sliding layer can be arbitrarily changed in a wide range, preferably,
0.1 to 5 mm. If the surface layer is thinner than 0.1 mm, abrasion resistance is deteriorated. On the contrary, if the surface layer is thicker than 5 mm, a gap is formed between the surface layer and the buffer layer, which makes it difficult to fold the adhesive tape. Become. In addition, this surface sliding layer may be formed integrally with the underlying buffer layer, if necessary. For example, the entire surface may be formed of foamed polyurethane, and a thin polyurethane film may be formed on the surface. it can. Further, in order to improve the lubricity of the tape folded portion, for example, a silicone oil-based lubricant may be applied to the surface of this means.

In the sticking jig of the present invention, the third component is a tape winding portion. The tape winding portion can further wrap the adhesive tape folded into the tape attaching portion by the tape folding portion described above, and finally apply the adhesive tape in close contact with the tape attaching portion. In addition, a tape pressing member which can be brought into contact with an adherend in the presence of an appropriate pressing force by an attached pressing distance adjusting member is provided. In the tape winding section, by using the pressing distance adjusting member, the tape pressing member can be arranged at an arbitrary position according to the shape and size of the adherend, and therefore, can be placed on various adherends. When guiding the tape pressing member of the jig, an appropriate guide space without any extra gap between the adherend and the tape pressing member is guaranteed, and The adhesive tape can be appropriately wound and brought into close contact.

In order to form the guide space, at least a part of the tape pressing member of the tape winding section must be deformably supported on a support frame or an auxiliary member attached thereto. Therefore, a portion of the tape pressing member that is not involved in the formation of the guide space may be fixedly connected to the support frame or the auxiliary member by using an adhesive or the like.

In the sticking jig of the present invention, the tape pressing member of the tape winding portion is preferably formed of a flexible material. This flexible material
Any material may be used as long as it can provide a desired guide space at the time of deformation and guarantee the intended wrapping and sticking operation when using the jig. Suitable materials include, for example, natural and synthetic rubbers, foamed plastic materials, such as foamed polyurethane, various felt materials, and the like.

In a preferred aspect of the present invention, the tape pressing member of the tape winding portion is preferably a buffer layer made of an elastic material, and is provided on the buffer layer, and is used for attaching a tape to an adherend. And a surface sliding layer to be brought into contact with the adhesive tape on the site. Since the buffer layer is mainly used for improving the cushioning property of the jig, it is preferable that the buffer layer be made of an elastic material such as natural and synthetic rubber, a foamed plastic material such as foamed polyurethane, various felt materials, and the like. . The thickness of the buffer layer can be arbitrarily changed in a wide range, but is preferably 0.5 to 10 mm. If the buffer layer is thinner than 0.5 mm, the desired elasticity cannot be obtained. Conversely, if the buffer layer is thicker than 10 mm, it is difficult to deform the guide space, and it is difficult to form the guide space. There is a gap between the jig body and
Workability deteriorates. When the adherend is large and the attaching jig of the present invention is correspondingly large, the thickness of the buffer layer may be further increased to, for example, about 15 mm.

The surface sliding layer provided on the buffer layer is for smoothly moving the jig over the tape-attached portion of the adherend, and is therefore a fluorine-containing resin, especially Teflon ^™ resin, nylon, natural resin or the like. And it is preferable to be composed of synthetic leather, other tapes, sheets, fabrics and the like. Particularly, in consideration of slipperiness and abrasion resistance, use of leather is more preferable. The thickness of the surface sliding layer can be arbitrarily changed in a wide range, but is preferably 0.1 to 5 mm. If this surface layer is thinner than 0.1 mm, abrasion resistance deteriorates,
On the other hand, if the thickness is more than 5 mm, deformation for forming the guide space is not evident, and a gap is formed between the buffer layer and the adhesive layer, making it impossible to fold the adhesive tape. In addition, this surface sliding layer may be integrally formed with the underlying buffer layer, if necessary. For example, the entire surface is formed of foamed polyurethane, and a thin polyurethane coating is applied to the surface thereof. Can be mentioned. In order to improve the lubricity of the jig surface, for example, a silicone oil-based lubricant may be applied to the surface of the surface sliding layer.

In the sticking jig according to the present invention, the tape winding portion has a pressing distance adjusting member for deforming the tape pressing member in order to form a guide space by deformation of the tape pressing member. ing.
The pressing distance adjusting member is preferably movably mounted in the main body of the tape winding section. More specifically, the pressing distance adjusting member is formed from a material having excellent mechanical strength, such as metal or engineering plastic, in a pin or similar shape, and is opened at a predetermined portion of the main body of the tape winding portion. It can be used in the hole. Here, the hole of the main body of the tape winding part is
In consideration of factors such as the shape of the guide space to be formed by the deformation of the tape pressing member, it can be formed at an appropriate position on the rear side surface of the main body. The "rear side surface" means that when the attaching jig of the present invention is used, the jig is slid on the surface of the adherend and the adhesive tape is pressed, and the progress of the jig at that time It points to the rear side with respect to the direction. As described in the following embodiments, the tape winding portion is usually used in one or one pair, but may be used in two or more or two pairs or more as necessary. .

When the pressing distance adjusting member inserted into the main body of the tape winding portion is moved in the direction in which the tape pressing member of the tape winding portion is pushed out, the tape pressing member that has been brought into close contact with the inner wall of the main body is moved. Is pushed up by the tip of the pressing distance adjusting member, and is pushed out by the moving distance of the pressing distance adjusting member. As a result, the tape pressing member is deformed, and a desired guide space corresponding to the size and shape of the adherend is formed. According to the invention, the guiding space thus formed may be kept as it is, or else the pressing force may be held so as to be freely adjustable. That is, after the guide space is formed, when the pressing distance adjusting member is immobilized at a predetermined position by a stopper, specifically, a fixed member such as a ball plunger, the formed guide space is not changed and is not changed. Can be maintained. Further, after the guide space is formed, if the pressing distance adjusting member is movably suppressed by, for example, a biasing means such as a spring, or is suppressed by an operator's hand, the pressing force of the adhesive tape on the tape affixed portion is reduced. Can be adjusted freely.

In the sticking jig according to the present invention, the entire tape pressing member may be used to form the guide space as described above, otherwise, a part of the tape pressing member may be selectively used. May be used. For example, the guide space can be formed by a combination of the tape pressing member deformed by the pressing distance adjusting member and the tape pressing member fixedly connected to the main body of the tape winding portion. When the guide space is formed in this way, if the adherend is a long deformed adherend having a substantially uniform cross section and the tape-attached portion is a deformed portion of the adherend, pressing is performed. The tape pressing member deformed by the distance adjusting member and the tape pressing member fixedly connected to the main body of the tape winding portion are arranged to face each other with respect to the deformed portion of the adherend. There will be. The guide space may be formed by one or more pairs of the tape pressing members deformed by the pressing distance adjusting member. When the guide space is formed in this way, if the adherend is a long deformed adherend having a substantially uniform cross section and the tape-attached portion is a deformed portion of the adherend, pressing is performed. The pair of tape pressing members deformed by the distance adjusting member will be arranged to face each other with respect to the deformed portion of the adherend.

In the practice of the present invention, the adherend and the pressure-sensitive adhesive tape to be adhered thereto are the same as those generally used in this technical field as they are, or after being subjected to any appropriate improvement or modification. Can be used with For example, the adherend is a vehicle such as an automobile, a building,
It covers a wide range of articles, such as other structures, machinery and home appliances. In addition, the pressure-sensitive adhesive tape may be a pressure-sensitive adhesive layer such as an acrylic adhesive, an epoxy-based adhesive, a urethane-based adhesive, a silicone-based adhesive, a phenol-based adhesive, and a vinyl chloride on an arbitrary substrate such as paper and plastic materials. It may be one provided with a layer such as a system adhesive. These pressure-sensitive adhesive tapes may or may not have a liner such as release paper for protecting the pressure-sensitive adhesive layer. The size of the adhesive tape is arbitrary, from narrow to wide. If necessary, it may be in the form of a sheet or a film. Further, the sticking jig of the present invention can be applied to the application of a tape-shaped product to articles having various different shapes, as required, instead of sticking an adhesive tape.

The sticking of the adhesive tape to the adherend using the sticking jig according to the present invention can be performed from the beginning to the end of the tape sticking without using a squeegee or a similar means as in the conventional tape sticking. . The application of the adhesive tape can be usually performed according to the following procedure. 1. The tip of the adhesive tape that has passed through the tape path of the tape crimping part is also used for positioning at any part of the tape affixed part of the adherend (it is sufficient if there is enough area for the adhesive tape to adhere). Glue.

2. The jig is slid from the tape-attached portion (start end) of the adherend to which the tape is adhered to the end of the tape-attached portion, and is advanced. 3. As the jig advances, the pressure-sensitive adhesive tape is folded so as to wrap around the tape-attached portion, and is adhered to the adherend by the pressing force of the jig. 4. At the stage where the jig has left the end of the tape application portion of the adherend, the operation of attaching the adhesive tape to the adherend is completed. No wrinkles or air bites occur, and no additional work such as further pressing the applied adhesive tape with a squeegee is required.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In the following description, the present invention will be described with an example of a sticking jig particularly suitable for sticking an adhesive tape to an adherend having a T-shaped cross section, but the present invention is not limited to this embodiment. Please understand that it is not.

FIG. 3 is a side view showing a preferred example of a jig for sticking an adhesive tape according to the present invention. Sticking jig 10
Can be roughly divided into, in order from the traveling direction (arrow A) of the jig, a tape crimping portion 11 having a tape attaching head 4;
A tape folding section 12 having a folding head 7 which can be brought into contact with an adherend 20 by an elastic member 6, and a tape having a tape pressing member 9 which can contact the adherend 20 by a pressing distance adjusting member 8. It has a winding 13, each means having a common plastic support frame 3. The surface layer of the folding head 7 and the tape pressing member 9 are each made of a polyurethane foam so that the pressure-sensitive adhesive tape 1 can be properly and smoothly performed when abutting against the adherend 20, as will be specifically described below. It is composed of a surface sliding layer consisting of a layer and leather. As shown in the drawing, the adhesive tape 1 is separated from the release paper 2 after passing through a space as a tape path of the tape crimping unit 11, and is pressure-bonded to the tape-attached portion of the adherend 20.

As shown in FIG. 4, the tape crimping portion 11 is attached to the support frame 3 with plastic overhanging members extending in the horizontal direction from above and below, respectively. The tape path 5 which forms the approach path and the guide path of the adhesive tape is formed. Further, the lower overhang member is provided with a rubber tape application head 4 for positioning an adhesive tape at the tape application site of the adherend and pressing the adhesive tape. The surface of the tape applying head 4 is coated with Teflon ^{™ in} consideration of sliding friction with the adhesive tape. In the present invention, the tape application head 4 may be formed of an elastic material other than rubber, and a lubricating material other than Teflon ^™ coating may be applied to the surface.

As shown in FIG. 5, the tape fold 12 is attached to the support frame 3, the elastic member 6 used as a biasing means (here, a tension spring is used), and the support frame 3. The folding head 7 is rotatably supported at the tip of the support leg (this portion is also referred to as an “arm” in the specification of the present application). The support frame 3 and the end of the folding head 7 are connected by an elastic member 6, and the center of the folding head 7 is rotatably supported as described above.
The tip of the folding head 7 can be turned in the direction of the arrow. The elastic member 6 may be made of an elastic material piece such as a rubber strip instead of the tension spring. In consideration of sliding friction with the adhesive tape, a buffer layer made of an elastic material (here, polyurethane foam is used) is provided on the surface layer at the distal end of the folding head 7,
A surface sliding layer made of leather is laminated. Although a pair of tape folds is used in the illustrated example, a plurality of pairs of tape folds may be used as necessary.

As shown in FIG. 6, the tape winding portion 13 is provided on the support frame 3 and on the inner wall of the support frame 3 (more precisely, on the inner wall of the arch member which extends downward from the support frame 3 and is attached). It comprises a tape pressing member 9 attached thereto and a pressing distance adjusting member 8 for extruding the tape pressing member 9 by a required distance to provide an appropriate space for guiding the adherend. The tape pressing member 9 can be brought into contact with the adherend in the presence of an appropriate pressing force, and as shown in a cross section in FIG. 10, a buffer layer made of an elastic material (here, polyurethane foam is used). 14 and a surface sliding layer 15 (in this case, using leather) to be brought into contact with the pressure-sensitive adhesive tape.

The operation of the tape winding portion 13 shown in FIG. 6 can be easily understood from the sectional view shown in FIG. The pressing distance adjusting member 8 (here, a metal pin is used) is shown in FIG.
At the stage of release of 0 (A), it is housed in the hole of the support frame 3 and is not in contact with the tape pressing member 9. Next, prior to the start of the sticking operation of the adhesive tape,
A guide space for the adherend corresponding to the shape and size of the adherend to be attached is formed. First, the pressing distance adjusting member 8 is pushed toward the support frame 3, and the tape pressing member 9 that has been in contact with the supporting frame 3 is pushed inward. When the tape pressing member 9 is pushed out to a predetermined position as shown in FIG. 10B, the stopper 16 (here, a ball plunger is used) works, and the pressing distance adjusting member 8 is fixed. Therefore, the guide space (not shown) formed by the movement of the tape pressing member 9 can maintain its shape during the subsequent sticking operation. In the illustrated example, the pressing distance adjusting member 8 may be formed of a threaded shaft, a bolt or a screw instead of the metal pin.

The use of the jig for applying the pressure-sensitive adhesive tape according to the present invention can be easily understood from the steps shown in FIGS. First, as shown in FIG. 7, a release paper is applied to the upper surface of the adherend 20 (here, a door sash made of a plastic member having a rounded end surface) using a tape crimping portion 11. Adhesive tape 1 after removal (here, blackout film is used)
Position and attach the main part. Adhesive tape 1
Is pressed by the tape applying head 4 by the movement of the tape pressing section 11 and is attached to the adherend 20.

The adhesive tape 1 whose main part is adhered to the adherend 20 is then sent to a tape folding part 12 located behind a tape crimping part 11. In the tape folding section 12, as shown in FIG. 8, the folding head 7 is rotated and moved to a position suitable for folding the end of the adhesive tape 1 into the adherend 20 by the action of the elastic member 6. ing. Therefore, the end of the adhesive tape 1 is folded along the edge of the adherend 20 as shown. Since the folding head 7 is urged by the elastic member 6, the folding operation of the adhesive tape 1 is performed.
And it can be performed in a state where a uniform pressure is always applied to the adherend 20.

The adhesive tape 1 is sent to the tape winding section 13 following the adhesive tape folding operation shown in FIG. That is, a guide space is formed as shown in FIG. 10B, the pressing distance adjusting member 8 is fixed by the stopper 16, and then the adherend 20 is placed in the guide space for the adherend formed thereby. Then, the attaching jig (tape winding portion 13) is slid and advanced toward the end of the tape attaching portion. As the sticking jig advances, the tape 1 is folded so as to wrap around the tape sticking portion of the adherend 20, and is adhered to the adherend 20 by the pressing force of the tape pressing member 9. Since the tape winding section 13 is located behind the tape folding section 12, the winding of the adhesive tape 1 can be performed gradually following the folding, and the adherend 20 is covered with the tape pressing member 9 and fixed. By doing so, the adherend 20 and the attaching jig can always be kept at a fixed position. Then, when the attaching jig leaves the end of the tape attaching portion of the adherend 20, the operation of attaching the adhesive tape 1 to the adherend 20 is completed.
