  Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings. In this description, specific shapes, materials, numerical values, directions, and the like are examples for facilitating the understanding of the present invention, and can be appropriately changed according to the application, purpose, specification, and the like. In addition, when a plurality of embodiments and modifications are included in the following, it is assumed from the beginning that these characteristic portions are used in appropriate combinations.

  FIG. 1 is a diagram showing a schematic configuration of a label fitting system 1 of the present embodiment. As shown in FIG. 1, a label fitting system 1 includes a label base material supply unit 2 that supplies a label base material LM, an accumulator 4 that conveys the supplied label base material LM while making a U-turn a plurality of times, and an accumulator. 4, a projection forming device 5 for forming a plurality of dot-like projections on the surface of the label base LM supplied from 4, and the label base LM on which the projections are formed are cut into a predetermined length to obtain individual labels L After the label is generated, each label L is opened in a cylindrical shape to be fitted in the container B, and the container B is sequentially passed through the label fitting position α immediately below the label fitting apparatus 6. And a container transport unit 7 for transporting.

  The label base material supply unit 2 includes a base material roll 3 around which a label base material LM which is a long cylindrical shape and is folded into a sheet shape is wound. As the base material roll 3 rotates in the direction of arrow A, the label base material LM is fed out from the base material roll 3. Here, the label substrate LM is formed, for example, by printing or the like on a single-layer or multi-layer heat-shrinkable film substrate having a thickness of 15 to 60 μm made of polyester resin, polystyrene resin, polyolefin resin, or the like. It is a cylindrical film body that is folded into a sheet shape with individual labels continuously connected. In particular, the surface on which the protrusion is formed is preferably made of at least a polyester resin or a polystyrene resin.

  The accumulator 4 holds the fed label base material LM more than a predetermined length by transporting the label base material LM continuously fed from the base material roll 3 of the label base material supply unit 2 while making U-turns a plurality of times. It has a function to keep. In this way, by supplying the label base material LM to the downstream side via the accumulator 4, it is possible to stably feed out while suppressing the fluctuation of the tension acting on the label base material LM.

  The label base material LM that has passed through the accumulator 4 is conveyed in the direction of the arrow while being guided by a plurality of guide rollers R1, R2, and R3. In the present embodiment, the label base material LM is conveyed vertically upward between the guide rollers R1 and R2, is conveyed along the horizontal direction between the guide rollers R2 and R3, and after passing through the guide roller R3, it is directed vertically downward. Are transported.

  A protrusion forming device 5 is installed in the conveyance path of the label base material LM fed out from the label base material supply unit 2. Specifically, the protrusion forming device 5 is arranged close to the upper side of the label base material LM that is conveyed along the horizontal direction between the guide rollers R2 and R3.

  The projection forming device 5 is a device that forms a plurality of dot-like projections in a pattern on the surface of the label substrate LM. Here, the “pattern shape” includes a Braille shape, a row shape, a staggered shape, a matrix shape, a lattice shape, and the like. The plurality of protrusions formed by the protrusion forming device 5 function as braille that means the contents, precautionary notes, etc. when the individual protrusions are cut into individual labels and fitted into the container as will be described later. It functions as an anti-slip when gripping. A specific configuration of the protrusion forming device 5 will be described later.

  In addition, in this embodiment, it is installed facing the film part of one side (this embodiment upper side) among the two film parts which comprise the label base material LM folded in the sheet shape by the long cylinder shape. However, as shown by the alternate long and short dash line in FIG. 1, it may be placed opposite to the film portion on the other side (the lower side in this embodiment). In this way, since the protrusions can be formed on both surfaces of the label base material LM folded into a sheet shape, the protrusions can be formed in a wider area on the label surface. The function to be performed can be made more effective.

  Further, in the present embodiment, an example in which the protrusion forming device is installed so as to form the protrusion on the label base material LM that is conveyed in the horizontal direction is shown, but the present invention is not limited to this, and is along the vertical direction. One or a plurality of protrusion forming apparatuses may be installed to face one or both sides of the label substrate to be conveyed.

  For example, the label base material LM on which the protrusions constituting Braille are formed by the protrusion forming device 5 is introduced into the label covering device 6 after the conveying direction is changed from the horizontal direction to the vertical direction by the guide roller R3.

  The label fitting device 6 cuts a label base material LM folded into a sheet shape in a long cylindrical shape into a predetermined length to generate individual labels L, and opens the label L downward while opening the label L in a cylindrical shape. It is a device that is transported and fitted onto the outer periphery of the body of the container B. A specific configuration of the label fitting device 6 will be described later.

  The container transport unit 7 has a function of transporting the container B so that the container B sequentially passes through the label fitting position α directly below the label fitting apparatus 6. The container conveyance part 7 can be comprised by a conveyor, a rotary table, etc., for example. A sensor (not shown) detects that the container B transported by the container transport unit 7 has approached the label fitting position α, and opens in a cylindrical shape from the label fitting device 6 when the container reaches the label fitting position α. The released label L is discharged downward and fitted onto the outer periphery of the container B.

  Next, the protrusion forming apparatus 5 will be described in detail with reference to FIGS. FIG. 2 is a diagram illustrating a schematic configuration of the protrusion forming device 5 provided in the label fitting system 1. FIG. 3 is a plan view of the main part of the projection forming device 5 of FIG. 2 and the label base material LM as seen from above. In FIG. 3, the example in which the projection part formed on the label base material LM comprises Braille is shown. 4 is a cross-sectional view taken along the line DD in FIG.

  As shown in FIG. 2, the protrusion forming device 5 includes a mark sensor 12, a head 14, a curing device (curing unit) 16, and an inspection device (inspection unit) 18 in order from the upstream side in the conveyance direction of the label base material LM. Are arranged side by side. Further, the protrusion forming device 5 includes a tank 20 for storing fluid resin, a controller 22 for controlling the operation of the head 14, and a pattern and a forming position of the protrusion 26 formed on the label base material LM. An input device (input unit) 24 capable of inputting instructions is provided.

  The mark sensor 12 detects a cut mark CM formed on the label base material LM by printing or the like. The mark sensor 12 can be constituted by an optical sensor including a light emitting element and a light receiving element, for example. By operating the head 14 at a timing when a predetermined time has elapsed after the cut mark CM is detected by the mark sensor 12, each label L included in the label base material LM continuously connected via the planned cutting line CL. Protrusions 26 can be formed in the desired surface area above.

  In addition, you may abbreviate | omit the mark sensor 12 of the protrusion formation apparatus 5 by using the mark detection signal by the mark sensor contained in the label covering apparatus 6 mentioned later.

  The head 14 is a device for forming a protrusion 26 protruding in a dot shape on the surface of the label base LM in a pattern by discharging a fluid resin in the form of droplets toward the label base LM. It is. The head 14 is connected to the tank 20 by a pipe line and can receive the resin to be discharged.

  For the head 14, for example, a Braille print head manufactured by Gyger can be used. One head 14 may be provided, and a plurality of heads may be arranged side by side in the width direction or the conveyance direction of the label base material LM as necessary. FIG. 3 shows an example in which four heads are juxtaposed in the width direction of the label base material LM.

  An ionizing radiation curable resin such as an ultraviolet (UV) curable resin can be suitably used as the resin that forms the protrusions 26. However, the protrusion 26 is not limited to the ionizing radiation gland curable resin, and may be formed of a resin having other fluidity, for example, a hot melt adhesive.

  An ionizing radiation curable resin is a mixture of prepolymers (including oligomers) and / or monomers having a polymerizable unsaturated bond or cationic polymerizable functional group in the molecule, and can be cured by ionizing radiation. A composition. Examples of the ionizing radiation curable resin include epoxy (meth) acrylate, urethane (meth) acrylate, polyester (meth) acrylate, polyfunctional (meth) acrylate, polyether (meth) acrylate, silicone (meth) acrylate, and polybutadiene. Examples include (meth) acrylates such as (meth) acrylate and polystyryl (meth) acrylate, unsaturated polyester / styrene, polyene / thiol, copolymers thereof, and mixtures of two or more thereof. In particular, those containing epoxy (meth) acrylate are preferred. In addition, "(meth) acrylate" here means acrylate or methacrylate.

  The hot melt adhesive is an adhesive that is solid at room temperature and can be attached to the label substrate LM by heat melting. Hot melt adhesives include, for example, olefin polymers; urethane polymers; ester polymers; silicone polymers; ethylene-vinyl acetate copolymers, ethylene- (meth) acrylic ester copolymers, ethylene-acrylic acid. Copolymer, ethylene copolymer such as ethylene-methacrylic acid copolymer; styrene-butadiene-styrene block copolymer (SBS), styrene-isoprene-styrene block copolymer (SIS), styrene-ethylene -Styrene polymers such as butylene-styrene-block copolymer (SEBS) and styrene-ethylene-propylene-styrene block copolymer (SEPS); Olefin-based elastomers such as ethylene-α-olefin, ester-based elastomers, amide-based elastomers Such Thermoplastic elastomers; as a main component of the base polymer such as a hot melt adhesive containing these singly or two or more thereof. The hot melt adhesive can be attached to the surface of the label base material LM in a spot shape by using, for example, a known hot melt gun.

  In particular, the protrusion 26 is formed on the label base LM whose surface on which the protrusion 26 is formed is made of at least a polyester resin or a polystyrene resin, using an ionizing radiation-curable resin containing epoxy (meth) acrylate. According to this, it is possible to satisfactorily provide the protruding portion 26 without subjecting the label base material LM to a pretreatment such as corona treatment, roughening, or hydrophilization water immersion.

  Referring again to FIGS. 2 and 3, the curing device 16 of the projection forming apparatus 5 is a device that cures the projections 26 formed on the label base material LM by the head 14. Specifically, when the protrusion 26 is formed of an ultraviolet curable resin, the curing device 16 cures the protrusion 26 by irradiating the protrusion 26 with ultraviolet light.

  However, the curing device 16 may be any device that is suitable for curing the resin that constitutes the projections 26. For example, when a hot melt adhesive is used to form the projections 26, for example, cooled air or the like. Curing may be promoted by spraying the refrigerant.

  The inspection apparatus 18 is an apparatus that inspects whether or not the protrusions 26 are properly formed in a predetermined pattern on the label base material LM. The inspection device 18 includes, for example, a camera that images the label base material LM from above, and image information captured by the camera is transmitted to the controller 22. Note that the inspection device 18 is not an essential component in the present invention, and may be omitted. Specifically, the inspection device 18 may be omitted when the projecting portion 26 formed in a pattern does not fulfill the Braille function.

  The controller 22 is electrically connected to the components of the protrusion forming device 5 to control the operation of each part, and the protrusion 26 is properly formed by analyzing the image input from the inspection device 18. It has a function to detect whether or not. The controller 22 can be configured by a computer including a CPU, a ROM, a RAM, and the like, for example. Further, the controller 22 has a function of inspecting whether or not the projections 26 are normally formed by analyzing the image transmitted from the inspection device 18, and the projections 26 are missing. If this is the case, alert the operator with sound, light, etc., or attach a detection member such as a tack seal so that it can be detected by a defective product discharge means (not shown) provided downstream. The defective product can be discharged and removed.

  An input device 24 is connected to the controller 22. As described above, the input device 24 is a device that can input an instruction regarding the pattern, formation position, and the like of the protrusions 26 formed on the label base material LM. The input device 24 can be configured by a keyboard, a mouse, a touch panel, or the like, for example. When the operator inputs the formation pattern of the protrusions 26 via the input device 24, the controller 22 can control the operation of the head 14 accordingly and change the pattern and formation position of the protrusions 26. Therefore, the pattern and the like of the protrusion 26 can be easily and quickly instructed and changed on demand.

  In the present embodiment, when the label base material LM is cut into a predetermined length in the label fitting device 6 and each label L is generated, each label L is opened in a cylindrical shape, and the original of the label base material LM A first region extending in the label length direction including the fold position, and a second region extending in the label length direction at a position shifted by a predetermined angle in the label circumferential direction with respect to the first region. A plurality of protrusions 26 are formed in a pattern on the surface of the label to be removed.

  This will be described in detail with reference to the label base material LM shown in FIG. 3. Of the label base material LM folded into a sheet shape with a long cylindrical shape, both side edge portions E1 and E2 in the label width direction are labeled bases. The hatched areas corresponding to the original fold positions of the material LM and extending in a strip shape in the label length direction including these original fold positions correspond to the first areas 28a and 28b.

  In the present embodiment, the hatched areas extending in a strip shape along the label length direction including the center line O in the label width direction in the label base material LM correspond to the second areas 29a and 29b. The second region 29a shown in FIG. 3 is an outer surface region of the upper film portion of the two film portions constituting the label base material LM, and the second region 29b is the second region 29a in the lower film portion. It is the outer surface area in the position where it overlaps.

  The first regions 28a, 28b and the second regions 29a, 29b are used for transferring belts, rollers, and the like when the label L is transferred along the guide member while being opened in a substantially cylindrical shape in the label fitting device 6 described later. This is the area that will come into contact with the means. The width W of each of the first regions 28a and 28b and the second regions 29a and 29b is set to be slightly larger than the contact width of the transfer means of the label fitting device 6. Accordingly, by forming the protrusion 26 on the label surface excluding the first regions 28a and 28b and the second regions 29a and 29b, a transfer means such as a belt for transferring the label L in the label fitting device 6 is provided. The protrusion 26 on the label L is not contacted, and as a result, the protrusion 26 can be prevented or suppressed from peeling off from the label L and falling off.

  Fig.4 (a) is DD sectional drawing of FIG. Since the label base material LM is formed of a resin film which is a long cylindrical shape and is folded into a sheet shape, two film portions that overlap each other, that is, one side (or upper side) film portion F1 and the other side ( Or the lower part) and the film portion F2. And in this embodiment, the protrusion part 26 is formed in the surface of the one side film part F1 facing the protrusion formation apparatus 5. FIG.

  The planar view shape of one protrusion 26 is not particularly limited, and for example, a substantially circular shape (including an oval shape) in plan view, a substantially rectangular shape in plan view, an elongated linear shape (including straight lines or arbitrary meander lines), and the like. Is mentioned. When used as Braille, the protrusion 26 is generally circular in plan view. In addition, a planar view shape means the shape seen from the normal line direction with respect to the surface of the one side film part F1.

  The size of one protrusion 26 is set as appropriate, but taking the case of the protrusion 26 having a substantially circular shape in plan view as an example, the diameter is about 0.5 mm to 3 mm.

  The protrusion height of one protrusion 26 is not particularly limited. However, when the protrusion height of the protrusion 26 is too low, the braille function or the anti-slip function cannot be sufficiently exhibited. In the case where the protruding height is too high, the presence of the protruding portion 26 may interfere with the use of the label. From such a point, the protrusion height of the protrusion 26 is preferably about 0.2 mm to 3 mm. In addition, the protrusion height of the protrusion part 26 is a height from the surface of the one side film part F1 to the highest point of the protrusion part 26.

  FIG. 4B is a cross-sectional view similar to FIG. 4A when the heat shield member 13 is interposed between the one-side film portion F1 and the other-side film portion F2 constituting the label base material LM. is there.

  When the label base material LM is composed of a heat-shrinkable film, the ionizing radiation curable resin and hot melt adhesive used as the fluid resin constituting the protrusions 26 are usually heated to increase the fluidity. Since the head 14 is discharged in the state, when the projection 26 is attached on the one side film portion F1, the two film portions F1 and F2 are in contact with or close to each other as shown in FIG. There is a possibility that the thermal influence reaches the other side film portion F2 to cause local heat shrinkage. Such local heat shrinkage may be eliminated to an inconspicuous degree by the heat shrinking process of the entire label after being fitted to the container, but otherwise there is a risk that the appearance of the label attached state will be poor. is there.

  Therefore, as shown in FIG. 4B, a heat shield member 13 made of, for example, a resin plate having low heat conductivity is interposed between the one-side film portion F1 and the other-side film portion F2, or FIG. As shown in c), by installing the cooling member 15 in contact with the other side film portion F2 side, it is made not to be affected by thermal effects such as ionizing radiation curable resin adhered on the one side film portion F1. Also good. The heat shield member 13 is disposed inside the cylindrical label base material LM, and both end portions thereof curved on a substantially ¼ arc are supported on the guide rollers R2 and R3 via the other film portion F2. Can be provided.

  Note that the heat shield member 13 may not be a plate-like member, and may be formed of, for example, a wire member that forms a heat shield gap between the one-side film portion F1 and the other-side film portion F2. Also good. Further, it is preferable that the heat shield member 13 and the cooling member 15 are provided not only at the position facing the head 14 but also at the position facing the inspection device 18. If it does in this way, it will suppress that the other side film part F2 of the label base material LM or both film parts F1 and F2 will be thermally contracted with the heat | fever of the ultraviolet lamp contained in the hardening apparatus 18, for example. it can. As shown in FIG. 4C, the cooling member 15 may be a metal roller that rotates while contacting the back surface of the label base material LM at a position opposite to the curing device 18, or may be disposed inside. You may use the type through which water, cooling air, etc. distribute | circulate.

  In the label L, the first regions 28a and 29b extending in a strip shape in the label length direction including the fold positions E1 and E2 of the label base material LM are at positions facing the label radial direction. In the present embodiment, in the label L, the two second regions 29a and 29b are positioned opposite to each other in the label radial direction at a position shifted by about 90 ° from the first regions 28a and 28b in the label circumferential direction. . As described above, the protrusions 26 constituting the Braille are formed on the label surface excluding the first regions 28a and 28b and the second regions 29a and 29b.

  Further, as shown in FIG. 5B, the protrusions 26 on the label surface may be formed of a plurality of rows of patterns or a matrix pattern aligned in the label length direction to fulfill the anti-slip function. In this case, the protrusion 26 may be formed on the entire label surface excluding the first regions 28a and 28b and the second regions 29a and 29b.

  5A and 5B, the protrusions 26 are preferably formed on the label surface excluding the vicinity of both ends in the length direction of the label L. This is to prevent the presence of the protrusions 26 from hindering cutting when the label base material LM is cut to generate individual labels L in the label fitting device 6 described later.

The movable blade 62 is rotationally driven by a motor (not shown) such as a servo motor or a stepping motor, for example, and the feeding operation of the label base material LM by the pitch feed roller unit 50 is temporarily stopped based on the mark detection signal from the mark sensor 30. During operation, the label L is controlled to be separated from the label base material LM.

  The cutting unit 60 is not limited to a guillotine type consisting of the above-described fixed blade and movable blade. For example, a type in which two movable blades relatively approach and separate may be used, or a fixed blade and a rotary movable blade may be used.

  The mandrel 70 opens in a predetermined state by fitting the label base material LM sent out by the pitch feed roller unit 50, and lowers the label L cut from the label base material LM by the transporting action of the transfer unit 80. It functions as a guide member when transported to

  The mandrel 70 has a label opening 71 having a tapered wedge shape on the upper end side, and a label shaping portion 75 having a circular cross section continuously provided at a lower portion of the label opening 71. The label base material LM fitted to the upper end portion of the label opening 71 is gradually opened by being transferred to the lower side of the label opening 71 and separated into individual labels L, followed by label shaping. By being fitted on the part 75, it is shaped into a cylindrical shape.

  In the lower half of the label opening 71 of the mandrel 70, a pair of upper rollers, which are paired in order from the top, with the peripheral surfaces slightly protruding from the upstream and downstream side surfaces in the transport direction of the container B, A middle roller and a lower roller (both not shown) are rotatably mounted. In addition, a pair of rollers (not shown) sandwiching the label L between the pair of shot rollers 91 at a position perpendicular to the conveyance direction of the container B are provided at the lower end of the label shaping unit 75 of the mandrel 70. It is attached so that it can rotate with the peripheral surface slightly protruding.

  The transfer unit 80 is sandwiched between the label opening 71 and the label shaping unit 75 with the label L separated from the label base material LM by the cutting unit 60 in a state of being fitted to the label opening 71 of the mandrel 70. It consists of feed belt units 80a and 80b disposed on the upstream side and the downstream side in the conveying direction of the container B in the mandrel 70 to be transferred. Each of the feed belt units 80a and 80b includes a drive pulley 81, four driven pulleys 82, 83, 84, and 85 and a narrow endless feed belt 86 (for example, about several millimeters) spanned between them. Has been.

  The drive pulley 81 and the driven pulleys 84 and 85 of the feed belt units 80a and 80b are disposed at positions corresponding to the lower roller, the upper roller, and the middle roller of the label opening 71 in the mandrel 70, respectively. A label L is sandwiched between the upper roller and the middle roller via a feed belt 86.

  Further, the drive pulley 81 and the driven pulleys 84 and 85 of the feed belt units 80 a and 80 b are rotatably supported by the same support member, respectively, and the driven pulley 85 is formed in the label opening 71 in the mandrel 70. By entering the recess, the mandrel 70 is supported via the middle roller.

  The shot roller unit 90 includes a pair of shot rollers 91. Each shot roller 91 is provided at a position facing the radial direction in the lower part of the label shaping portion 75 of the mandrel 70. Each shot roller 91 is directly connected to a rotation shaft of a shot roller motor composed of a servo motor. In the present embodiment, the shot roller 91 is disposed at a position shifted by 90 ° in the circumferential direction of the mandrel 70 with respect to the feed belt 86, and is provided to rotate along the axial direction of the mandrel 70. . Accordingly, when the shot roller 91 is rotated in a state where the label L fitted on the mandrel 70 is sandwiched between the shot roller 91 and the mandrel 70, the label L becomes the outer peripheral surface of the label shaping portion 75 of the mandrel 70. Will be sent downward along the line.

  In the label fitting device 6 configured as described above, the label base material LM and the individual labels L which are conveyed downward while opening along the outer periphery of the mandrel 70 are, as shown in FIG. 7, the second region 29a. , 29b contacts the respective feed belts 86 of the feed belt units 80a, 80b, and contacts the shot roller 91 in the first regions 28a, 28b as shown in FIG. Therefore, the protrusions 26 formed on the label surface other than the first regions 28a, 28b and the second regions 29a, 29b on the label base material LM and the label L do not contact the feed belt 86 and the shot roller 91, As a result, it is possible to prevent the protrusions 26 from being peeled off or dropped out due to contact with the feed belt 86 or the like.

  Moreover, according to this embodiment, since the projection part 26 is formed on the label base material LM after being fed out from the label base material supply unit 2, the label base material on which the projection part is formed is wound in a roll shape. Compared to the above, it is possible to wrap a long and long label base material on one roll without being bulky.

  In addition, this invention is not limited to the structure of embodiment mentioned above, A various change and improvement are possible within the matter described in the claim of this application, and its equivalent range.

  For example, as shown in FIG. 8, a folding guide 100 is provided on the inner side of the label base material LM and is folded at a position that is 90 ° out of phase in the label circumferential direction from the original fold positions E1 and E2. After that, it may be introduced into the label fitting device 6. This is because the label L cut and formed from the label base material LM can be easily opened in a cylindrical shape, or can be easily opened in a shape along the outer peripheral surface when the label L is fitted in a container B having a square cross section. . In this case, in the label base material LM, the second regions 29a and 29b are regions including the folding positions.

  When the label base material LM is folded in this way, the film portion corresponding to the folding position is subjected to a bending load, which may cause the protrusions to fall off. Therefore, it is preferable not to form the protruding portion 26 in such a region that becomes the folding position. However, when the label substrate LM folded as shown in FIG. 8 is introduced into the label fitting device 6 having the configuration shown in FIGS. 6 and 7, the second regions 29a and 29b including the folding positions are fed. Since this is a contact area with the belt 86, there is no problem of the protrusions falling off due to folding.

  Here, when the folding position is set to a different angular position other than 90 ° (for example, 50 °) with respect to the original folding position, the folding position is not included in the second regions 29a and 29b. It becomes. In that case, in the label base material LM and the label L, the region that does not contact the feed belt 86 and the shot roller 91 but includes the folding position is preferably a region that does not form a protrusion. Moreover, the label folding part may be provided on the upstream side of the protrusion forming device 5 with respect to the conveyance direction of the label base material LM.

  Moreover, in the said embodiment, although the case where the feed belt 86 and the shot roller 91 were arrange | positioned in the position which shifted | deviated 90 degrees regarding the circumferential direction of the mandrel 70 in the label fitting apparatus 6 was demonstrated, as shown in FIG. There are cases where the feed belt 86 and the shot roller 91 are arranged in the same phase. That is, the feed belt 86 and the shot roller 91 are included on the same vertical plane. In the case of this configuration, only the label substrate LM and the second regions 29a and 29b of the label L are regions that come into contact with the label transfer means. Therefore, in this case, the protrusions 26 may be formed in the first regions 28a and 28b of the label base material LM. However, as described above, in this case as well, when the first regions 28a and 28b of the label base material LM are regions including the folding positions, it is not necessary to form the protrusions 26.

  Moreover, in the said embodiment, although the protrusion formation apparatus 5 was provided in the upstream position close | similar to the label covering apparatus 6 regarding the conveyance direction of label base material LM, it is not limited to this, The label covering apparatus 6 It may be installed at an upstream position (for example, a position immediately after being fed out from the base roll 3).

  Furthermore, in the above-described embodiment, the description has been made on the assumption that the dot-shaped protrusions are formed on the label base material LM. However, the present invention is not limited to this. You may comprise so that a projection part may be formed, after being cut | disconnected by this label.

  Furthermore, in the above-described embodiment, the case where the label base LM and the label L are made of a heat-shrinkable film base has been described. However, the present invention is not limited to this. It may be applied to an elastic stretch label that is attached in close contact with the periphery of the part.
