Description

Button mounting device

Technical Field

The present invention relates to a button attaching device, and more particularly, to a button attaching device that holds one side of a fixing member when attaching a button body to a blank such as clothing by the fixing member.

Background

In the case of attaching the button body to the blank, generally, after the button body is held by an upper die and a fixing member is placed on a lower die, the upper die is lowered toward the lower die. The post of the fixing member is thus inserted upward through the blank, and then, after the post passes through the opening for attaching the button body, the post is swaged by the punch of the upper die. Thereby, the button body is fixed to the blank. The blank is compressed between the button body and the fixing member, and the rotation of the fixing member and the button body is prevented by friction generated by the reaction force of the compression. However, for example, when the blank is thin, the reaction force and friction are insufficient, and the button body to be attached may be rotated and easily detached. In such a case, conventionally, a gap in the thickness of the blank has been compensated by sandwiching a medium called a spacer between the fixing member and the blank. In addition, for the purpose of improving the design of clothes and the like, a spacer having an outer diameter larger than that of the button body may be interposed.

Japanese patent No. 6239952 (patent document 1) discloses the following technique: when the button body is attached to the blank by using the upper die and the lower die and the fixing member, the punch of the lower die punches a gasket band having a slit formed in advance on the outer periphery of the gasket from the slit, thereby sandwiching the gasket between the fixing member and the blank. However, in the technique of patent document 1, when the pad tape is made of a soft material such as felt, the fibers are not broken when the pad tape is punched by a punch, and thus defects are likely to occur. In addition, it is not easy to accurately align the center of the slit of the cushion belt with the center of the fixing member held by the lower die, and the center of the cushion and the center of the fixing member are liable to deviate.

Disclosure of Invention

Problems to be solved by the invention

Accordingly, an object of the present invention is to provide a button attaching device in which, even if a backing tape is made of a soft material such as felt, a defective punching is hardly generated and the center of the backing and the center of the fixing member do not deviate.

Solution for solving the problem

In order to solve the above-described problems, according to the present invention, there is provided a button attaching device for holding one side of a fixing member when attaching a button body together with the fixing member and a pad to a blank, the button attaching device comprising: a moving member for moving the fixing member from an initial position to an installation position; a tape passage intersecting a movement path between the initial position and the installation position of the fixing member, for a gasket tape to pass; and a cutting portion for cutting the gasket tape at an intersection of the moving path and the belt path to form the gasket, the cutting portion including a 1 st cutting portion penetrating the gasket tape from a 1 st surface to a 2 nd surface of the gasket tape.

When attaching the button body to a blank such as clothing, the moving member moves the fixing member from the initial position to the attachment position, and a part (e.g., a post) of the fixing member penetrates the blank, and the post of the fixing member is swaged to the button body held to the upper die at the attachment position, whereby the button body is fixed to the blank. In the present invention, a tape passage through which the gasket tape passes is provided so as to intersect a movement path between the initial position and the attachment position of the fixing member, and the gasket tape is cut out as a gasket by a cutting portion at an intersection of the movement path and the tape passage. The cut out liner is transported together with the fixed member by the moving member to the mounting position where it is sandwiched between the blank and the fixed member. In the present invention, since the cutting portion includes the 1 st cutting portion penetrating the backing tape from the 1 st surface to the 2 nd surface of the backing tape, the backing tape can be cut at once without forming a slit or the like in the backing tape in advance, and a backing having a beautiful outer periphery can be obtained even if the backing tape is a soft material such as felt. Further, since the cutting position at which the liner is cut out from the liner tape is set to the intersection of the moving path of the fixing member and the tape path, the liner cut out from the liner tape and the fixing member are automatically arranged concentrically, and the center of the liner and the center of the fixing member do not deviate.

In the present invention, the backing tape is a long strip-shaped body for cutting out a plurality of backing, and as a raw material of the backing tape, nonwoven fabrics such as felt, synthetic fibers such as nylon and polyester, leather, and the like can be cited, but the backing tape is not limited to these. The fixing member may be made of a metal such as an aluminum alloy or a copper alloy, or may be made of a thermoplastic resin or a thermosetting resin.

In one embodiment of the present invention, the cutout portion includes a 2 nd cutout portion that supports the 2 nd face of the cushion tape and has an opening capable of receiving the 1 st cutout portion that has penetrated the cushion tape. In this embodiment, when the 1 st cut portion penetrates the cushion tape from the 1 st surface to the 2 nd surface, the 2 nd cut portion supports the cushion tape from the 2 nd surface, and receives the 1 st cut portion, through which the cushion tape has been penetrated, at the opening. At this time, the cutting edge (the 2 nd cutting edge) between the surface facing the 2 nd surface of the gasket tape and the peripheral surface of the predetermined opening in the 2 nd cutting portion acts on the gasket tape at the same time as the cutting of the gasket tape by the 1 st cutting portion, and the cutting is promoted.

In one embodiment of the present invention, the 2 nd cutting portion has a 2 nd cutting edge between a surface facing the liner tape and a peripheral surface defining the opening, and a cutting edge position of the 2 nd cutting edge in a direction along an axis of the opening is varied. In this embodiment, the position of the cutting edge in the axial direction, which is the direction along the axis of the opening, of the 2 nd cutting edge is not necessarily changed. In this case, the time for which the 2 nd edge of the 2 nd cutting portion acts on the tape is shifted, and the tape can be gradually cut. Therefore, the load required for cutting the cushion belt can be reduced as compared with the case where the entire edge 2 acts on the cushion belt at the same time. For example, out of the circular 2 nd cutting edges, two cutting edge positions of the 1 st group, which are spaced 180 degrees apart from each other, are located at positions closest to the liner belt side of the belt path in the axial direction, and two cutting edge positions of the 2 nd group, which are separated from the cutting edge positions of the 1 st group by 90 degrees, are located at positions farthest from the liner belt, and can be set so that the cutting edge positions gradually change from the cutting edge positions of the 1 st group to the cutting edge positions of the 2 nd group. Alternatively, the cutting edge position may be changed so that the 2 nd cutting edge of the circular shape is formed in a wave shape so as to follow the circular shape along the outer periphery of the circular shape, and so as to follow one direction in the axial direction and then follow the other direction.

In one embodiment of the present invention, the 1 st cutout portion moves together with the moving member until penetrating the cushion belt.

ADVANTAGEOUS EFFECTS OF INVENTION

In the present invention, since the cutting portion includes the 1 st cutting portion penetrating the backing tape from the 1 st surface to the 2 nd surface of the backing tape, the backing tape can be cut at once without forming a slit or the like in the backing tape, and even if the backing tape is a soft material such as felt, a pad having a beautiful cut outer periphery can be obtained. Further, since the cutting position at which the liner is cut out from the liner tape is set to the intersection of the moving path of the fixing member and the tape path, the liner cut out from the liner tape and the fixing member are automatically arranged concentrically, and the center of the liner and the center of the fixing member do not deviate.

Detailed Description

Fig. 1 is a cross-sectional view showing an arrangement structure immediately before a button post (male snap member) 10 as an example of a button body is attached to a blank f such as a garment together with a fixing member 20 and a spacer 30. Fig. 2 is a sectional view showing a state in which the buttonhole 10, the fixing member 20, and the cushion 30 are mounted to the blank f. Hereinafter, unless otherwise specified, the upper and lower sides are the upper and lower sides of the paper surface based on fig. 1 to 12. The buttonhole 10 includes a substantially disk-shaped base 11 and an annular engaging portion 12 protruding upward from the base 11. The engaging portion 12 is detachable from an engaged portion 12a of a button base 10a (see fig. 3, etc.) which is a female snap fastener member. An opening 13 is provided in the center of the base 11. The fixing member 20 includes a disk-shaped base 21 and a cylindrical column 22 extending upward from the center of the base 21. When the buttonhole 10 is attached to the blank f, although details will be described later, a circular cushion 30 is cut out from a cushion tape PT (see fig. 6 and the like), and the post 22 of the fixing member 20 is then inserted upward through the cushion 30, then inserted upward through the blank f, and further passed through the opening 13 of the buttonhole 10, and then is caulked by the upper die 200 (see fig. 5). Thus, the buttonhole 10 is fixed to the blank f together with the fixing member 20 and the spacer 30, and the spacer 30 is sandwiched between the blank f and the fixing member 20.

Fig. 3 is a cross-sectional view showing an arrangement structure immediately before a button (female snap member) 10a as another example of a button body is attached to a blank f (for the pad 30 and the blank f, the same reference numerals as those of fig. 1 and the like are used for convenience) together with a fixing member 20 and a pad 30. Fig. 4 is a cross-sectional view showing a state in which the boss 10a, the fixing member 20, and the pad 30 are attached to the blank f. In this example, the buttonposts 10 and buttonholders 10a are mounted to the blank f with the same securing member 20, but different types of securing members can be used. The button 10a includes a disk-shaped base 11a and a substantially annular engaged portion 12a protruding upward from the base 11 a. The spring 14 is accommodated in the engaged portion 12a. An opening 13a is provided in the center of the base 11 a. The button seat 10a is also fixed to the blank f together with the fixing member 20 and the spacer 30, similarly to the button post 10 described above. As is clear from fig. 2 and 4, in this example, the spacer 30 is larger than the base 21 of the fixing member 20, but may be substantially the same size as the base 21 or smaller than the base 21.

Fig. 5 is a perspective view of button attaching device (lower die) 100 according to embodiment 1 of the present invention, and shows upper die 200 and conveying mechanism 300 of fixing member 20 in broken lines. Hereinafter, button bodies (10, 10 a) to be attached to a blank f (see fig. 1, etc.) by the button attaching device 100, etc. are described as button bodies 10, but the button bodies 10a and other button bodies are substantially the same. Fig. 5 shows the button attaching device 100 in a state of being accommodated in a rectangular parallelepiped housing 101. The housing 101 has a rear wall 102, a left side wall 103, a right side wall 104, and an upper wall 105, and a majority of the front portion opposite to the rear wall 102 is open. The upper wall 105 of the housing 101 has an opening 105a, and an upper portion of the button attaching device 100 is exposed to the outside of the housing 101 from the opening 105 a. The upper die 200 is disposed above the button attaching device 100. The conveying mechanism 300 is disposed on the rear wall 102 side of the housing 101. When the button body 10 is attached to the blank f, the fixing members 20 are automatically transported and supplied to the button attaching device 100 one by the transport mechanism 300. Thus, the fixing member 20 is held by a holding portion S (see fig. 7) of the button attaching device 100, which will be discussed later. The button body 10 is automatically supplied and held to the upper die 200 by a button body conveying mechanism, not shown. The fixing member 20 and the button body 10 can be manually held to the button attaching device 100 and the upper die 200, respectively.

Fig. 6 is a cross-sectional view of the button mounting apparatus 100 taken along line A-A of fig. 5. The button attaching device 100 includes: a cylindrical moving member 110 for moving the fixing member 20 from the initial position to the mounting position; an annular member 120 disposed so as to surround the moving member 110; a receiver 130 that substantially houses a majority of the moving member 110 and the annular member 120; a tape passage 140 through which the cushion tape PT passes; and a cutting section 150 for cutting the cushion belt PT to obtain the cushion 30. In fig. 6, the fixed member 20, the moving member 110, the annular member 120, and the plunger 160 are located at initial positions as the lowest points. Hereinafter, a state in which the fixing member 20 and the like are positioned at the initial position is also referred to as an "initial state".

The moving member 110 includes a solid cylindrical upper portion 111 and a hollow cylindrical lower portion 112. The lower end portion of the lower portion 112 of the moving member 110 is coupled to a plunger 160 (only the upper end portion of the plunger 160 is shown), and the moving member 110 can reciprocate in a movement path along the up-down direction between an initial position (see fig. 6) and an uppermost mounting position (see fig. 10) by the plunger 160.

The annular member 120 includes: a thick portion 121 having a maximum outer diameter; a cylindrical 1 st cutting portion 151 protruding upward from the thick portion 121; and a lower inner cylinder 122 and a lower outer cylinder 123 extending downward from the thick portion 121. The thick portion 121, the 1 st cutout portion 151, and the lower inner tube portion 122 have the same inner diameter, which is substantially the same as the outer diameter of the moving member 110. The thick portion 121 has the same outer diameter as the lower outer tube portion 123, and the outer diameter is substantially the same as the inner diameter of the receiver 130. The 1 st cutting portion 151 of the annular member 120 is also a component of the cutting portion 150, and constitutes the cutting portion 150 together with a 2 nd cutting portion 152, which will be discussed later. The 1 st cutting portion 151 has substantially a constant inner diameter and outer diameter, but is a thin portion having a small thickness in the radial direction. The 1 st cutting portion 151 has a 1 st cutting edge 151a at an upper end.

Long holes 113 are provided in the opposite walls of the upper and lower intermediate portions of the lower portion 112 of the moving member 110, respectively. The coupling shaft 114 passes through the two elongated holes 113, and both end portions of the coupling shaft 114 are coupled to the lower inner cylinder portion 122 of the annular member 120. Thus, the moving member 110 is coupled with the ring member 120, and the ring member 120 can be linked with the moving member 110 to a position where movement to the upper side is restricted by the upper wall 132 of the receiver 130, which will be discussed later. Further, 1 or more compression springs 115 as elastic members are arranged between the lower surface of the thick portion 121 of the annular member 120 and the upper end surface of the plunger 160. An upper portion of the compression spring 115 is received between the lower inner cylinder 122 and the lower outer cylinder 123 of the annular member 120. The compression spring 115 pushes the ring-shaped member 120 upward with respect to the moving member 110 until the coupling shaft 114 comes into contact with the upper end of the long hole 113.

In the initial state, the 1 st cutout 151 of the annular member 120 protrudes upward from the upper surface 110a so as to surround the upper surface 110a of the moving member 110. In this way, in the initial state, a space S surrounded by the 1 st cutout 151 and opened upward is generated on the upper surface 110a of the moving member 110. The space S is a holding portion S for receiving and holding the fixing member 20 supplied from the conveying mechanism 300. In the example of the fixing member 20, the upper end of the post 22 of the fixing member 20 held to the holding portion S in the initial state is located slightly above the 1 st cutting edge 151a of the 1 st cutting portion 151.

The receiver 130 is a member that keeps a stationary state with respect to the moving member 110 and the annular member 120 that move up and down. The receiver 130 includes a peripheral wall 131 and an upper wall 132, and is opened downward. The outer shape of the peripheral side wall 131 is, as shown in fig. 5, a shape in which four corners of a rectangular parallelepiped having a square horizontal cross section are chamfered. Accordingly, the peripheral side wall 131 has a front wall 131a, a rear wall 131b, a left side wall 131c, a right side wall 131d, and 4 corners 131e. The rear wall 131b of the receiver 130 is disposed on the conveying mechanism 300 side. A circular 1 st opening 133 is provided in the center of the upper wall 132. The diameter of the 1 st opening 133 is slightly larger than the outer diameter of the 1 st cut-off portion 151. The inner space of the peripheral sidewall 131 has a cylindrical shape, and the peripheral sidewall 131 has a certain inner diameter. The inner diameter is substantially the same as the outer diameter of the annular member 120. The upper wall 132 of the receiver 130 functions as a stopper that receives the thick-wall portion 121 of the ring member 120 that moves upward and restricts the movement of the ring member 120 further upward.

The cutting portion 150 includes the 1 st cutting portion 151 and the 2 nd cutting portion 152 provided upward with a slight gap from the upper wall 132 of the receiver 130. A tape passage 140 is provided between the upper wall 132 of the receiver 130 and the 2 nd cutout 152. In other words, the upper surface of the upper wall 132 defines the lower surface of the tape passage 140, and the lower surface of the 2 nd cutout 152 defines the upper surface of the tape passage 140. An introduction portion 142 for introducing the cushion tape PT into the tape passage 140 is provided at an upper end portion of the right side wall 131d of the receiver 130. Further, a discharge portion 141 for discharging the liner tape PT after the cut liner 30 is discharged from the tape passage 140 is provided at the upper end portion of the left side wall 131c of the receiver 130. The introduction portion 142 has an introduction surface 142a inclined upward toward the downstream side of the belt path 140, and the discharge portion 141 has a discharge surface 141a inclined upward toward the upstream side of the belt path 140. The 2 nd cutout 152 is connected to the front wall 131a and the rear wall 131b of the receiver 130. The cushion tape PT is wound out from a winding-out section, not shown, and is introduced into the tape passage 140 from the right introduction section 142, and is discharged from the left discharge section 141 through the tape passage 140. The cushion tape PT discharged from the tape passage 140 is wound by a winding portion, not shown. Accordingly, the band pass 140 can be said to be along the left-right direction. Reference numeral 148 in fig. 6 denotes a conveying roller for discharging the liner belt PT from the belt path 140, and reference numeral 149 denotes a passive roller for passing the liner belt PT between it and the conveying roller 148. Further, the conveying roller 148 and the driven roller 149 may be simultaneously rotated by interlocking the conveying roller 148 and the driven roller 149 by gears or the like. The conveying roller 148 is intermittently rotationally driven by a driving source (e.g., a motor) not shown. Thereby, the cushion belt PT is intermittently conveyed to the belt path 140.

The position of the tape path 140 between the 1 st opening 133 and the 2 nd opening 153 is a cutting position where the cushion tape PT is cut by the 1 st cutting portion 151 and the 2 nd cutting portion 152 to form a circular cushion 30 as will be discussed later. The channel 140 in the left-right direction as described above can be said to intersect or be orthogonal to the movement path in the up-down direction between the initial position and the attachment position of the fixing member 20. The cutting position is set at the intersection of the movement path and the tape path 140. An upper portion of the rear wall 131b of the receiver 130 is provided with a receiving portion 134 for receiving the fixing member 20 supplied from the conveying mechanism 300 in the button mounting apparatus 100. The fixing member 20 received from the receiving portion 134 is seated on the holding portion S in the initial state.

As shown in fig. 5, the 2 nd cutout 152 is a plate having substantially the same shape as the outer shape of the peripheral side wall 131 of the receiver 130. The 2 nd cutout 152 has a circular 2 nd opening 153 in the center. The diameter of the 2 nd opening 153 is substantially the same as the outer diameter of the 1 st cut-off portion 151, and is sized to snugly receive the 1 st cut-off portion 151. The boundary between the peripheral surface of the 2 nd opening 153 and the lower surface of the 2 nd cutting portion 152 is defined as a 2 nd cutting edge 154. The 2 nd cutting portion 152 supports the cushion tape PT from above when the 1 st cutting portion 151 penetrates the cushion tape PT from below to above as will be discussed later. In the present embodiment, the 2 nd cutting portion 152 serves to support the blank f to which the button body 10 is attached by the upper surface.

Next, a process of attaching the button body 10 to the blank f by the button attaching device 100 will be described. Fig. 7 is an enlarged view showing a state immediately before the cutting section 150 cuts the cushion tape PT. Fig. 8 is a cross-sectional view showing the button attaching device 100 immediately after the cushion tape PT is cut. Fig. 9 is a cross-sectional view of the button attaching device 100 showing a timing when the elevation of the annular member 120 is restricted by the receiver 130. Fig. 10 is a cross-sectional view of the button attaching device 100 showing the timing when the fixing member 20 reaches the attaching position. In the initial state shown in fig. 6, the fixing member 20 is supplied from the conveying mechanism 300 to the button attaching device 100 and held by the holding portion S. On the other hand, the button body 10 is held by the upper die 200. The blank f is disposed on the 2 nd cutting portion 152 of the button attaching device 100. Also, the cushion belt PT passes through the belt passage 140. The carrier tape PT stops being conveyed during the step of attaching 1 button body 10 to the blank f. When the plunger 160 located at the lowermost point starts to rise from the initial state, the moving member 110 and the annular member 120 rise, and the fixed member 20 also rises from the initial position by the moving member 110. Next, as shown in fig. 7, the upper ends of the posts 22 of the fixing member 20 and the 1 st cutout 151 are brought into contact with the cushion belt PT. In this example, the upper end of the post 22 is located slightly above the 1 st cutting edge 151a of the 1 st cutting portion 151, and therefore, the post 22 of the fixing member 20 slightly lifts the cushion belt PT at the time when the 1 st cutting edge 151a is in contact with the cushion belt PT.

When the moving member 110 and the annular member 120 further rise from the timing of fig. 7, as shown in fig. 8, the 1 st cutting portion 151 penetrates from the lower surface of the 1 st surface to the upper surface of the 2 nd surface of the liner tape PT, and the liner tape PT at the cutting position is cut into a circular shape by the 1 st cutting edge 151a of the 1 st cutting portion 151 and the 2 nd cutting edge 154 of the 2 nd opening 153. Thereby, the circular gasket 30 is formed. By sandwiching and cutting the cushion tape PT with the lower 1 st cutting edge 151a and the upper 2 nd cutting edge 154, the cushion tape PT can be cut at once without forming a notch or the like in the cushion tape PT in advance. Further, since the cushion belt PT is cut at the cutting position that is the intersection of the belt path 140 and the movement path of the fixing member 20, the cushion 30 and the fixing member 20 can be automatically aligned, and the center of the cushion 30 and the center of the fixing member 20 can be prevented from being deviated.

Next, the moving member 110 and the annular member 120 continue to rise, and at this time, the packing 30 rises while being supported by the 1 st cutting edge 151a of the 1 st cutting portion 151 (and the column 22 of the fixing member 20 in this example). At the timing shown in fig. 9, thick portion 121 of annular member 120 contacts upper wall 132 of receiver 130, and movement thereof further upward is restricted. Thereafter, the plunger 160 continues to rise, and therefore the compression spring 115 between the thick-wall portion 121 of the annular member 120 and the plunger 160 starts to contract in the up-down direction. The moving member 110 also continues to rise together with the plunger 160, whereby the upper end of the long hole 113 is separated from the coupling shaft 114. The column 22 of the fixed member 20 lifted by the moving member 110 passes through the spacer 30 upward, and then passes through the blank f to reach the attachment position shown in fig. 10. At this time, the post 22 of the fixing member 20 passes upward from the opening 13 of the button body 10. At the timing of fig. 10, the plunger 160 and the moving member 110 are at the uppermost point, and the ascent is stopped. Then, the post 22 of the fixing member 20 is swaged to the button body 10 held by the upper die 200, whereby the spacer 30 is sandwiched between the base 21 of the fixing member 20 and the blank f, and the button body 10 is attached to the blank f. Thereafter, upon return of the plunger 160 and the moving member 110 to the lowermost point, the pad belt PT conveys one amount of the pad 30 downstream in the band passage 140.

Fig. 11 is a cross-sectional view of a button attaching device 100a according to embodiment 2 of the present invention. The main points of the structure of the button attaching device 100a that differ from the button attaching device 100 of embodiment 1 are that: the 2 nd cutout 152a is disposed in the receiver 130a at an upper end portion thereof contacting the upper wall 132a of the receiver 130 a; a tape guide 143 for supporting the pad tape PT passing through the tape path 140 from below; the position of the 2 nd cutting edge 154a of the 2 nd cutting portion 152a changes in the axial direction (up-down direction). The other structures are substantially common to the button attaching device 100 described above, and therefore the same reference numerals as those of the button attaching device 100 are used, and the description thereof is omitted. In the button mounting apparatus 100a, the upper wall 132a of the receiver 130a supports the blank f with an upper surface. The tape guide 143 is disposed below the 2 nd cutting portion 152a with a slight gap therebetween, and the tape path 140 is set between the 2 nd cutting portion 152a and the tape guide 143. The tape guides 143 are supported on the front and rear walls of the receiver 130 a.

The tape guide 143 has an opening 143a in the center. The 2 nd cutout 152a also has a 2 nd opening 153a in the center. Furthermore, the upper wall 132a of the receiver 130a also has a 1 st opening 133a in the center. The diameter of the 2 nd opening 153a is substantially the same as the outer diameter of the 1 st cut-off portion 151, and is sized to receive the 1 st cut-off portion 151. The 1 st opening 133a is slightly larger than the 2 nd opening 153a, and the opening 143a is slightly larger than the 2 nd opening 153a. In the button attaching device 100a, when the moving member 110 moves up together with the annular member 120 to move the fixing member 20 from the initial position to the attaching position, the 1 st cutting edge 151a of the 1 st cutting portion 151 cuts the pad tape PT located at the cutting position of the tape path 140 between the 1 st cutting edge 151a and the 2 nd cutting edge 154a of the 2 nd cutting portion 152a after passing through the opening 143a of the tape guide 143, thereby forming the circular pad 30. Next, the thick portion 121 of the annular member 120 contacts the tape guide 143 to restrict the upward movement. Thereafter, the moving member 110 also continues to rise, and the fixing member 20 is moved to the mounting position. The pad 30 is sandwiched between the base 21 of the fixing member 20 and the blank f, and the button body 10 is attached to the blank f.

Fig. 12 is an enlarged view showing a state immediately before the 1 st cutting portion 151 and the 2 nd cutting portion 152a cut the cushion tape PT in the button attaching device 100 a. The cutting edge position of the 2 nd cutting edge 154a of the 2 nd cutting portion 152a varies in the axial direction. In more detail, two cutting edge positions 154aa of the 1 st group, which are 180 degrees apart from each other, of the 2 nd cutting edge 154a are located at positions closest to the liner belt PT side (2 nd surface) of the band pass 140 in the axial direction, and two cutting edge positions 154ab of the 2 nd group (only 1 cutting edge position 154ab is shown) which are 90 degrees apart from the cutting edge positions 154aa of the 1 st group are located at positions farthest from the liner belt PT. Further, the 2 nd cutting edge 154a gradually changes the cutting edge position from the 1 st cutting edge position 154aa to the 2 nd cutting edge position 154 ab. By changing the edge position of the 2 nd edge 154a in the axial direction in this way, the cushion belt PT can be gradually cut, and the load required for cutting the cushion belt PT can be reduced.
