Description of the Related Art There are a number of products on the market in which a synthetic resin film, an adhesive tape or the like is wound in a roll, and these products are wound around a paper tube, a so-called paper tube. ing. The core paper tube is generally manufactured as follows. That is, for example, to manufacture a paper tube having an inner diameter of 80 mm and a paper thickness of 2 mm, a width of 1 mm is required.
A high quality paper of 00 mm is spirally wound around a metal tube mandrel having an outer diameter of 80 mm so that the edges in the longitudinal direction of the paper are in contact with each other (this paper forms the innermost layer of the paper tube). . Next, a long cardboard having a width of 100 mm and a thickness of 0.5 mm is coated with an adhesive on the entire inner surface thereof, and then spirally wound so that the edges in the length direction of the cardboard are in contact with each other. Wound on the high quality paper to integrate the high quality paper and cardboard. Next, a long cardboard having a width of 100 mm and a thickness of 0.5 mm is coated with an adhesive over the entire inner surface thereof, and then wound in a spiral shape so that the edges in the longitudinal direction of the cardboard are in contact with each other. The cardboard is wound on the cardboard, and the high quality paper and the two layers of cardboard are integrated. This cardboard winding operation is performed a total of four times (that is, the cardboard layer becomes four layers). Thereafter, a long kraft paper having a width of 100 mm is coated with an adhesive over its entire inner surface, and then spirally formed. The kraft paper is wound on the wound cardboard such that the edges in the length direction of the kraft paper are in contact with each other, and the whole is bonded and integrated. Thus, a long paper tube in which the innermost layer of high quality paper, the four layers of cardboard, and the outermost layer of kraft paper are integrated is obtained. The long paper tube is extracted from the metal tube and cut to a desired length to produce a product paper tube.

提供することを目的とする。FIG. 8 is a front view showing a state in which both ends of the raw material cardboard are connected with the paper adhesive tape as described above using the conventional paper adhesive tape. Here, 6 is the end of the cardboard of the first roll, 7 is the tip of the cardboard of the new roll, and 8 is the joint at both ends. 1 is a paper as a base material of the paper adhesive tape, and 2 is its pressure-sensitive adhesive layer. 3 is a release agent layer. As is clear from FIG. 8, when the conventional paper adhesive tape is used, the release agent layer 3 is present on the back surface of the paper adhesive tape at the connection portion.
Then, when the raw material cardboard connected with this conventional paper adhesive tape is spirally wound, and when the cardboard coated with an adhesive on the inside to be the next layer is wound thereon, it is wound first. Since the release agent layer exists on the back surface of the paper adhesive tape at the connection portion of the cardboard, the cardboard does not adhere to each other at that portion. That is, there is a portion that is not bonded in the paper layer of the paper tube. The unbonded portions have poor strength, and the cardboard is lifted, resulting in poor appearance.
For this reason, the part where the defective bonding portion exists must be discarded. The number of unbonded defective portions increases as the number of cardboard layers increases. Although it depends on the type of paper tube, it is said that the ratio of discarded parts reaches 6 to 8% due to the defective bonding. An object of the present invention is to solve this problem and to provide a pressure-sensitive adhesive sheet for connection so that a connection point of cardboard as a raw material for a paper tube can be used as a product.
