Even with this distance, if the winding position of the adhesive tape 5 is shifted due to irregular rotation or the like of the reel 1 during winding of the adhesive tape 5, or the position of the adhesive tape 5 which has been wound is shifted due to impact or vibration during storage, the adhesive tape 5 may come in contact with the inner surface of the side plate 2.

In addition, the height hl of less than 0.05 mm is not preferable, since the injection molding conditions of the reel 1 are required to be controlled accurately. On the other hand, if the height hl of the projection 21 exceeds 1.00 mm, the projection 21 becomes excessively high, affecting the width dimensions of the reel 1. In addition, this height is not preferable since pushing pressure to the side surface of the adhesive tape 5 increases, and as a result, the side surface of the adhesive tape 5 may acquire marks from the projection 21.

If the width w1 of the projections 21 is less than 0.5 mm, the side surface of the adhesive tape 5 may become damaged. In addition, the width w1 of the projection 21 of less than 0.5 mm is not preferable since the injection molding conditions of the reel 1 are required to be controlled accurately. On the other hand, when the width w1 of the projection 21 exceeds 20.0 mm, the adhesive may adhere to the projection 21.

- the adhesive tape 5 is wound around the reel 1 which rotates in the direction shown by the arrow.
- the peripheral projection 22 provided on the inner surface along the peripheral part of the side plate 2 serves to prevent adherence of the adhesive constituting the adhesive layer to the peripheral part of the side plate 2, which is caused by the contact of the adhesive layer exposed on the side surface of the adhesive tape 5 with the peripheral part of the side plate 2 when winding the adhesive tape 5 around the reel 1 as mentioned above.

If the height h2 of the peripheral projection 22 is less than 0.05 mm, the effects of suppressing contact of the adhesive tape 5 with the inner surface of the side plate 2 are impaired. In addition, such a small height of the peripheral projection 22 is not preferable since the adhesive tape 5 may become scratched due to interference of the projection 21 and the adhesive tape 5 when winding the adhesive tape 5.

FIG. 8 is a conceptual view showing the positions of the projections provided on the inner surface of the side plate and the peripheral projections provided on the inner surface along the peripheral part of the side plate according to a modification example of the reel of the invention. - The preferred embodiments of the invention will be described with reference to the drawings.
FIG. 1 is an explanatory view showing the outline of the reel according to the invention, in whichFIG. 1(a) is a front view andFIG. 1(b) is a cross sectional view ofFIG. 1(a) taken along the line A-A inFIG. 1(a) . - A
reel 1 shown inFIG. 1 is provided with a columnar wind-upunit 3 and a pair ofside plates unit 3 is between the side plates. A D-shaped shaft hole 4 penetrates through almost the center of thereel 1. By inserting the wind-up shaft of a wind-up apparatus (not shown) into thisshaft hole 4, thereel 1 is installed on this wind-up apparatus, and the reel is allowed to rotate when the wind-up shaft is driven. - The
reel 1 with such a configuration is used for manufacturing and supplying variousadhesive tapes 5 by a method in which a film material on which an adhesive layer is formed by coating is cut into a narrow tape and the narrow tape is wound around the reel. The width of the wind-upunit 3, namely the distance between theside plates unit 3 can be appropriately set according to the cut width of anadhesive tape 5 as the object being wound. In addition, theside plate 2 is normally formed in a circular shape, and the diameter thereof can be appropriately set according to the winding length of theadhesive tape 5. - In this embodiment, the
reel 1 may be a reel which is integrally formed by injection molding or the like. However, the pair of theside plates unit 3 may be formed separately, and these parts may be connected by an appropriate means such as fitting and adhesion. By forming theside plates unit 3 separately, the following configuration can be realized. For example, theside plates 2 differing in diameter can be combined with the common wind-upunit 3, thereby allowing thereel 1 to correspond to various winding lengths, or the wind-upunits 3 differing in width can be combined with thecommon side plate 2, thereby allowing the reel to correspond to various cutting widths. - In this embodiment, as shown in
FIG. 1 (b) andFIG. 2 , aprojection 21 extending in the radial direction is provided on the inner surface of theside plates
Fig. 2 is an end view taken along the line B-B inFIG. 1(b) . - The
projection 21 provided on the inner surface of theside plate 2 serves to avoid contact of the adhesive layer exposed on the side surface of anadhesive tape 4 with the inner surface of the reel 1 (inner surface of the side plate 2) when winding up theadhesive tape 5 around thereel 1 or during the storage of the woundadhesive tape 5, whereby the adhesive constituting the adhesive layer is prevented from adhering to the inner surface of thereel 1. - That is, the distance between the
side plates unit 3, is set to be larger to some extent than the cut width of theadhesive tape 5 such that theadhesive tape 5 to be wound around the wind-upunit 3 is prevented from being adhered to the inner surface of theside plate 2. Even with this distance, if the winding position of theadhesive tape 5 is shifted due to irregular rotation or the like of thereel 1 during winding of theadhesive tape 5, or the position of theadhesive tape 5 which has been wound is shifted due to impact or vibration during storage, theadhesive tape 5 may come in contact with the inner surface of theside plate 2.
In this embodiment, even in such a case, by providing aprojection 21 on the inner surface of theside plate 2, the contact area of the adhesive layer exposed on the side surface of theadhesive tape 5 and the inner surface of theside plate 2 can be reduced, whereby adherence of the adhesive constituting the adhesive layer to the inner surface of thereel 1 can be prevented. - In this embodiment, when
such projection 21 is provided, the height hl of theprojection 21 is preferably 0.05 to 1.00 mm, more preferably 0.05 to 0.30 mm, and particularly preferably 0.05 to 0.20 mm.
If the height hl of theprojection 21 is less than 0.05 mm, it may be hard to obtain the effects of suppressing contact of theadhesive tape 5 with the inner surface of theside plate 2. In addition, the height hl of less than 0.05 mm is not preferable, since the injection molding conditions of thereel 1 are required to be controlled accurately. On the other hand, if the height hl of theprojection 21 exceeds 1.00 mm, theprojection 21 becomes excessively high, affecting the width dimensions of thereel 1. In addition, this height is not preferable since pushing pressure to the side surface of theadhesive tape 5 increases, and as a result, the side surface of theadhesive tape 5 may acquire marks from theprojection 21. - The width w1 of the
projection 21 is preferably 0.5 to 20.0 mm, more preferably 0.5 to 10.0 mm, and particularly preferably 0.5 to 5.0 mm.
If the width w1 of theprojections 21 is less than 0.5 mm, the side surface of theadhesive tape 5 may become damaged. In addition, the width w1 of theprojection 21 of less than 0.5 mm is not preferable since the injection molding conditions of thereel 1 are required to be controlled accurately. On the other hand, when the width w1 of theprojection 21 exceeds 20.0 mm, the adhesive may adhere to theprojection 21. - In this embodiment, as shown in
FIG. 1 , radial provision of a plurality of (8 in the shown example)projections 21 which extend in the radial direction is preferable, since adherence of the adhesive constituting the adhesive layer to the inner surface of thereel 1 can be prevented more surely. - In this embodiment, on the inner surface along the peripheral part of the
side plate 2, theperipheral projection 22 extending in the circumference direction are provided as shown inFIG. 1(b) andFIG. 3 .
FIG. 3 is an end view showing the cross section taken along the line C-C inFIG. 1(b) . - When winding the
adhesive tape 5 around thereel 1, which has been cut to have a narrow width, as shown inFIG. 4(a) , if theadhesive tape 5 is slightly tilted and the side surface of theadhesive tape 5 is guided by the peripheral part of theside plate 2, theadhesive tape 5 can be wound uniformly with flushed stacked side surfaces of the woundadhesive tape 5.
FIG. 4 is an explanatory view showing the winding-up state of theadhesive tape 5.FIG. 4(b) is a left side view of the state shown inFIG. 4(a) . In this figure, theadhesive tape 5 is wound around thereel 1 which rotates in the direction shown by the arrow. - In this embodiment, the
peripheral projection 22 provided on the inner surface along the peripheral part of theside plate 2 serves to prevent adherence of the adhesive constituting the adhesive layer to the peripheral part of theside plate 2, which is caused by the contact of the adhesive layer exposed on the side surface of theadhesive tape 5 with the peripheral part of theside plate 2 when winding theadhesive tape 5 around thereel 1 as mentioned above. - That is, in this embodiment, when guiding the side surface of the
adhesive tape 5 with the peripheral part of theside plate 2, in order to reduce the contact area with theadhesive tape 5, theperipheral projection 22 extending in the circumference direction is provided on the inner surface along the peripheral part of theside plate 2 to suppress the adhesion of the adhesive. - Therefore, it is preferred that at least part of the
peripheral projection 22 which is in contact with theadhesive tape 5 have a circular shape. The radius of curvature thereof is preferably 0.3 to 1.5 mm, more preferably 0.5 to 1.0 mm in order to reduce the contact area of theperipheral projection 21 with theadhesive tape 5. - In this embodiment, in providing such
peripheral projection 22, the height h2 of theperipheral projection 22 is preferably 0.05 to 1.00 mm, more preferably 0.05 to 0.30 mm, and particularly preferably 0.05 to 0.20 mm.
If the height h2 of theperipheral projection 22 is less than 0.05 mm, the effects of suppressing contact of theadhesive tape 5 with the inner surface of theside plate 2 are impaired. In addition, such a small height of theperipheral projection 22 is not preferable since theadhesive tape 5 may become scratched due to interference of theprojection 21 and theadhesive tape 5 when winding theadhesive tape 5. If the height h2 of theperipheral projection 22 exceeds 1.00 mm, theperipheral projection 22 becomes excessively high, and as a result, theperipheral projection 22 may interfere with theadhesive tape 5 when winding up theadhesive tape 5. In addition, since the gap between the woundadhesive tape 5 and theside plates adhesive tape 5 is completed, weaving may occur during storage, resulting in lowered storage stability. - The width w2 of the
peripheral projection 22 is preferably 0.5 to 20.0 mm, more preferably 0.5 to 10.0 mm, and particularly preferably 0.5 to 5.0 mm.
If the width w2 of theperipheral projection 22 is less than 0.5 mm, the side surface of theadhesive tape 5 may become scratched. If the width w2 of theperipheral projection 22 exceeds 20.0 mm, the problem of adherence of the adhesive to theperipheral projection 22 occurs. In addition, when theadhesive tape 5 which has been wound up around thereel 1 is unwound for use, theadhesive tape 5 may become caught in theperipheral projection 22. - The preferred embodiments of the invention have been described hereinabove. The invention is not limited to the embodiments mentioned above, and it is needless to say that various modifications are possible within the scope of the invention.
- For example, in the above-mentioned embodiments, both of the pair of
side plates projection 21 or theperipheral projection 22. However, if necessary, the radially-directedprojection 21 and theperipheral projection 22 may be provided on only one of theside plates
That is, if theadhesive tape 5 is wound near one of theside plates 2 in order to increase the distance between theother side plate 2 and theadhesive tape 5, the radially-directed projection 2l' and theperipheral projection 22 can be provided on the oneside plate 2. - In the above embodiment, the
shaft hole 4 in the shape of the letter D is shown. However, theshaft hole 4 may contain a key groove corresponding to a key provided on the winding shaft. The specific configuration of theshaft hole 4 can be changed corresponding to a means for mounting the winding apparatus to the winding shaft. - In the above-mentioned embodiment, the configuration of the winding
unit 3 is roughly shown. The windingunit 3 may have various configurations which can be applied to this type of reel, for example, provision of a rib for ensuring rigidity. - In the above-mentioned embodiment, the
adhesive tape 5 provided with an adhesive layer is used as an object to be wound. However, the reel of the invention can preferably be applied to an object to be wound provided with a sticky layer formed by applying a material generally known as a "sticky adhesive". - In the above-mentioned embodiment, the
projections 21 provided on the inner surface of theside plate 2 are provided as a concave line formed continuously from the inner perimeter to the outer perimeter of thereel 1. However, as shown inFIG. 5(a) , theprojections 21 may be formed intermittently. Furthermore, theprojections 21 may be provided from the center of theside plate 2 to the periphery so that they extend in the radial direction. In addition, as shown inFIG. 5(b) , theprojections 21 may be provided such that they intersect with the radial direction, and, as shown inFIG. 5(c) , theprojections 21 may be provided in a spiral shape.
If theprojections 21 are provided radially, the radial center thereof is preferably the same as the center of theside plate 2. However, it is possible to allow the radial center and the center of theside plate 2 to be different, if necessary. Furthermore, it is possible to form theprojections 21 in such a manner that theprojections 21 extend radially from each of these different radial centers. - Furthermore, the shape of the cross section of the
projection 21 is not limited to the above-mentioned circular shape. The cross section may have a rectangular shape or a rectangular shape with round corners, or the like. The cross section may have a shape as shown inFIG. 6 . - As mentioned above, there are no specific limitations on specific aspects, e.g. the number or shape of the
projection 21 provided on the inner surface of theside plate 2, insofar as adherence of the adhesive to the inner surface of thereel 1 can be prevented. - As in the case of the
peripheral projection 22 provided along the peripheral part of theside plate 2, various modifications are possible, as long as adherence of the adhesive can be prevented when winding is performed while guiding the side surface of theadhesive tape 5 with the peripheral part of theside plate 2.
In the above-mentioned embodiment, theperipheral projection 22 is provided along the entire circumference of the peripheral part of theside plate 2. However, as shown inFIG. 7(a) , the peripheral projection may be provided intermittently along the peripheral part of theside plate 2. In addition; as shown inFIG. 7 (b) , the peripheral projection may be provided in a spiral form, and as shown inFIG. 7(c) , a plurality of (2 in the in the shown example)peripheral projections 22 may be arranged in parallel to each other.
Furthermore, as shown inFIGs. 8(a) to (c) , theperipheral projections 22 provided intermittently may be connected with theprojections 21, which is provided to avoid adherence of the adhesive to the inner surface of thereel 1. - The cross section of the
peripheral projection 22 may have the same shape as that of theprojection 21. Specifically, it may have a circular shape, a rectangular shape, a rectangular shape with round corners, or a shape shown inFIG. 6 . - Here,
FIGs. 5 ,7 and8 are explanatory views which conceptually show the positions of theprojections FIG. 6 is an explanatory view which shows the outline of the shape of the cross section of the projection 21 (or peripheral projection 22).FIGs. 6(d) and (f) show two projections 21 (or peripheral projections 22) which are arranged in parallel in such a manner that they are dose to each other, andFIGs. 6(e) and (g) show two projections 21 (or peripheral projections 22) which are arranged in such a manner that they are in contact with each other. - As mentioned hereinabove, the invention provides a reel used to manufacture and supply an adhesive tape, which prevents adherence of an adhesive to the inner surface thereof.
