Detailed Description

Embodiments of the invention will be described in further detail with reference to the drawings, it being understood that the examples are illustrative only and should not be taken as limiting the invention, and that all of the features disclosed in the examples or all of the steps in any method or process disclosed herein can be combined in any way, except for mutually exclusive features and/or steps.

Traditional adhesive tape is formed by arranging several round web-shaped adhesive tapes side by side, because the cross-section of each adhesive tape all is circular or approximate circular in the adhesive tape for between the adjacent adhesive tape, because of reasons such as action of gravity or squeezing action, lead to adjacent adhesive tape in the adhesive tape to produce the bonding/adhesion of great area extremely easily, as shown in figure 6, this is because the adhesive tape cross-section is circular and leads to, separate the difficulty between the adjacent adhesive tape after bonding. The adhesion between adjacent strips can be divided into: longitudinal bonding, namely bonding between a first adhesive tape 91 and a third adhesive tape 93 in the figure; transverse bonding, bonding between the first adhesive tape 91 and the second adhesive tape 92. Longitudinal bonding is typically produced when a section of a strip is cut, which results from the bonding of layers of the same strip. The transverse bond is usually produced when separating different strips arranged side by side, which is produced by a bond between different strips arranged side by side. The main purpose of this embodiment is to solve the two adhesion problems described above.

The technical scheme of the utility model for providing a rubber strip is rolled up, including adhesive tape main part 10, be equipped with arch 20 on the adhesive tape main part 10, arch 20 is the strip, and arch 20 arranges along adhesive tape extending direction, and wherein, has at least one side position to be equipped with the arch 20 of bar in the adhesive tape main part 10. When the strip-shaped protrusion 20 is arranged at the upper side and/or the lower side of the adhesive tape main body 10, the view directions of fig. 4 and fig. 6 are taken as reference directions, the effect of reducing longitudinal adhesion can be achieved; when the strip-shaped protrusion 20 is disposed at the left and/or right position of the adhesive tape main body 10, it can play a role of reducing the lateral adhesion. Specifically, referring to fig. 3 and 4, when the adhesive tape is wound in a roll shape, the protrusion 20 is located on the outer side or the inner side of the adhesive tape, so that the protrusion 20 of the adhesive tape after winding is located between layers of the adhesive tape. Replace direct contact between the adhesive tape through utilizing protruding 20 and adhesive tape main part 10 contact, can reduce area of contact between the adhesive tape, protruding 20 can provide a support simultaneously, avoids laminating tension between the adhesive tape to reach the effect that reduces vertical bonding, vertical bonding reduces the back, and operating personnel when certain section on an intercepting adhesive tape, can be convenient many.

In order to further enhance the adhesion reducing effect, it is preferable that at least 2 strip-shaped projections 20 are provided at each side position on the strip main body 10. The 2 bar-shaped protrusions 20 provide two supports, under which the strip of glue is less prone to stick together than the one support provided by the 1 bar-shaped protrusions 20.

Preferably, 2 bar-shaped protrusions 20 are arranged in parallel.

Preferably, the bulge 20 is pointed, with the bulge 20 having a larger dimension at a location close to the main body 10 of the strip and a smaller dimension at a location remote from the main body 10 of the strip. In this way, the contact area between the projections 20 and the strip body 10 can be made as small as possible, reducing the adhesion between the strips. Specifically, the cross-section of the protrusion 20 is triangular.

Preferably, there is a region 30 between 2 protrusions 20, and the region 30 allows two protrusions 20 to be spaced apart from each other without being too close. Further, this area 30 is planar or is sunken form, it should be noted that planar or be sunken form on the area 30 that is sunken form the arbitrary position all be less than protruding 20 to the distance of adhesive tape main part 10 center, this makes the adhesive tape when the contact (including the contact between same adhesive tape layer and the layer, and the contact between different adhesive tape row and the row), all the time protruding 20 contacts another adhesive tape main part 10 (including another part adhesive tape main part 10 of same adhesive tape, and the adhesive tape main part 10 of another adhesive tape) earlier. Further, the area 30 is preferably planar, since planar more easily provides a support point for the bulge 20 on one glue strip body 10 with another glue strip body 10: even if the strip is being wound, there is a winding excursion (not perfectly aligned with the winding), as shown in FIG. 5; or the height difference exists between the side-by-side adhesive tapes, and the effect of better reducing the bonding effect can still be achieved.

Preferably, strip-shaped protrusions 20 are arranged on two sides of the rubber strip body 10. Especially, the two sides are spaced by 180 degrees, for example, the upper and lower sides of the rubber strip main body 10 are provided with strip-shaped protrusions 20, or the left and right sides of the rubber strip main body 10 are provided with strip-shaped protrusions 20. By comparison, strip-shaped bulges 20 are arranged at one side of the rubber strip main body 10, and 2 bulges 20 are arranged at each side of the rubber strip main body, so that one contact position can provide two supports; when strip-shaped protrusions 20 are arranged at two side positions on the rubber strip main body 10, and 2 protrusions 20 are arranged at each side position, one contact position can provide four supports. Although the quantity of the supports among the adhesive tapes is increased, the adhesion among the adhesive tapes is not easy, but the adhesive tapes are not easy to adhere, because the protrusions 20 are pointed, and the pointed protrusions 20 have smaller contact areas and have better support effects. As shown in the attached drawings 4 and 5, the upper side and the lower side of the rubber strip main body 10 are provided with 2 strip-shaped bulges 20, and the effect of greatly reducing longitudinal bonding can be achieved at the moment.

Preferably, strip-shaped protrusions 20 are provided on four sides of the main body 10. Especially, the adjacent two side positions are separated by 90 degrees, for example, strip-shaped bulges 20 are arranged on the upper side and the lower side of the rubber strip main body 10, and strip-shaped bulges 20 are arranged on the left side and the right side of the rubber strip main body 10. Thus, the two problems of transverse bonding and longitudinal bonding can be solved simultaneously.

In the practical use of the strip, it is generally easier for the strip to bond in the longitudinal direction relative to the transverse direction, i.e. less so in the transverse direction relative to the longitudinal direction. When the technical scheme that the two bulges 20 are arranged on the upper side and the lower side of the adhesive tape in the longitudinal direction is adopted, the problem of longitudinal bonding can be well solved; for the side-by-side arrangement of the glue strips, the glue strip body 10 is not necessarily provided with two protrusions 20 in the transverse direction (left and right sides), but can be replaced by other simpler technical solutions. For example, one side is provided with only one protrusion and the region 30 is no longer required, it being noted that although protrusions are provided both longitudinally and transversely: structurally, the bead of the main body 10 for reducing the transverse adhesion (left and right) and the bead of the main body 10 for reducing the longitudinal adhesion (left and right) are different from each other. In order to better distinguish the two protrusions, the protrusion for reducing longitudinal bonding on the adhesive tape main body 10 is a first protrusion 41, the protrusion for reducing transverse bonding on the adhesive tape main body 10 is a second protrusion 42, only one second protrusion 42 is respectively arranged on the left side and the right side (along the direction of the adhesive tapes side by side) of the adhesive tape main body 10, the second protrusion 42 is 90 degrees apart from the first protrusion 41, the second protrusion 42 is also pointed, for example, the cross section of the second protrusion 42 is triangular, for the first protrusion 41, the cross section of the second protrusion 42 is far larger than that of the first protrusion 41, and the angle of the tip of the second protrusion 42 is far larger than that of the first protrusion 41. When the second projection 42 is triangular in cross-section, the tip angle is preferably 120-170, for example 150.

In addition, the partial technical solutions can be applied separately for the problem of transverse bonding, and the application does not depend on the technical solution for longitudinal bonding. The utility model provides a rubber strip is rolled up, including two piece at least adhesive tape main parts 10, different adhesive tape main parts 10 are arranged side by side, and every adhesive tape main part 10 is equipped with the protruding 42 of second along the symmetry in side by side direction, and the protruding 42 of second is the strip, and the protruding 42 of second is arranged along adhesive tape extending direction, and the protruding 42 of second is located between the adjacent adhesive tape main part 10.

Preferably, the second protrusion 42 is spaced 90 ° from the first protrusion 41.
