To explain an example below, a core 1 for an adhesive tape of the present invention has a core 2 and a double-sided adhesive tape 9 is spirally applied around the outer periphery of the core at the same pitch interval, with the release paper 4 outside and an adhesive layer. 3, and consists of a cutout paper 5 on the outside of the double-sided adhesive tape, and a supporting paper 6 wrapped around the outer circumference of the cutout paper.In this case, the double-sided adhesive tape is attached with the same Since it is arranged in a spiral pattern at pitch intervals,
Not only is the amount used reduced, but the adhesive layer with release paper can be easily formed on the core in one step. Core 1 for the above adhesive tape
To wrap the adhesive tape on the support paper, wrap the adhesive tape 7
Attach and fix the tip of the tape and wrap it to the required length.
After winding a certain length, the core body 2, the double-sided adhesive tape 9 attached to its outer periphery, and the paper 5 on the outside are wrapped together with the supporting paper 6.
and 7 layers of adhesive tape wrapped around its outer circumference. When the cutout paper 5 and the release paper 4 of the double-sided adhesive tape are peeled off from the core, the double-sided adhesive tape, and the cut-out paper, the adhesive layer 3 of the double-sided adhesive tape is stuck in a spiral shape with an interval. and remains on the core body 2. In the above-mentioned peeling process, since the double-sided adhesive tape has a spiral shape with intervals, the adhesive side of the release paper is extremely thin, so it can be easily peeled off from the adhesive layer and easily removed together with the cut-out paper. can. The core body 2 having the adhesive layer 3 is loosened into the hollow part of the support paper around which the extracted adhesive tape is wound. In this way, a gap 8 corresponding to the thickness of the cutout paper 5 and the release paper 4 is formed between the adhesive tape layer 7 with support paper and the core with the adhesive layer. Due to this gap, even if the tape roll contracts in the radial direction due to the tension of the tape, the tape will not protrude laterally, and the so-called bamboo shoot phenomenon will not occur. Further, as described above, the support paper 6 is adhered to the core body inserted into the hollow part of the support paper through the adhesive layer 3 (Fig. 3), and the adhesive tape 7 and the core body 2 are integrally bonded. By doing so, the adhesive tape 7 can be held in the correct shape without being laterally displaced from the core body 2. Conventionally, the core 2 is removed from the tape roll 7 along with the paper 5, the paper is removed from the core, and then the adhesive 3 is applied to the core 2.
Since the core body is inserted into the adhesive tape roll again after being applied to the outer periphery of the adhesive tape, an adhesive application process is required, and the manufacturing process of the adhesive tape roll is complicated and time-consuming, and production efficiency is low. When using adhesive tape cores, there is a pre-formed adhesive on the core after removing the cutout paper and release paper as described above, so the adhesive application process is omitted and the production efficiency of tape rolls is increased. can be improved.
