【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、タック紙やラベル等の形成用材料として
用いられるスリットを有する積層紙の製造方法に関する
ものである。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing laminated paper having slits used as a material for forming tack paper, labels, and the like.
表面基材の裏面に粘着剤層を形成し、その粘着剤層に
離型紙を貼り合わせた３層構造の長尺な積層紙を一方向
に移送し、その積層紙を先端より所定の長さに切断して
タック紙を形成し、あるいは表面基材と粘着剤層を所定
の形状に切断してラベルを形成することは従来から普通
に行なわれている。An adhesive layer is formed on the back surface of the front base material, and a long laminated paper having a three-layer structure in which a release paper is bonded to the adhesive layer is transferred in one direction, and the laminated paper is moved from the front end to a predetermined length. Conventionally, it is conventionally performed to form a tack paper by cutting into pieces, or to cut a surface base material and an adhesive layer into a predetermined shape to form a label.
上記タック紙として、離型紙の剥離を容易とするた
め、第３図に示すように、表面基材１の片面に塗布した
粘着剤層２およびその粘着剤層２を保護する離型紙３に
スリット４を入れたものがある。As shown in FIG. 3, a slit is formed in the adhesive layer 2 applied to one surface of the surface substrate 1 and the release paper 3 for protecting the adhesive layer 2 as shown in FIG. Some have four.
上記スリット４は、普通、タック紙を形成する前段に
おいて、積層紙に形成され、従来は、次の２つの製造方
法があった。The slit 4 is usually formed in laminated paper before forming tack paper. Conventionally, there have been the following two manufacturing methods.
第１の方法は、離型紙の片面に粘着剤を塗布し、乾燥
処理して粘着剤層を形成し、この帯状離型紙の粘着剤層
の上に表面基材を貼り合わせた後、この帯状離型紙を剥
がして粘着剤層を表面基材に転写し、さらに、他の離型
紙に長さ方向にスリットを入れて、表面基材に前記粘着
剤層の上から貼り合わせる方法である（例えば、特開昭
59−164584号参照）。The first method is to apply an adhesive on one side of a release paper, form a pressure-sensitive adhesive layer by drying treatment, attach a surface substrate on the adhesive layer of the release paper, and then apply This is a method in which the release paper is peeled off and the pressure-sensitive adhesive layer is transferred to the surface substrate, and further, a slit is made in another release paper in the length direction, and the pressure-sensitive adhesive layer is bonded to the surface substrate from above the pressure-sensitive adhesive layer (for example, , JP
59-164584).
また、第２の方法は、離型紙の片面に粘着剤層を形成
して、この離型紙と表面基材とを貼り合わせる一連の粘
着加工を行なったのち、回転する円形スリッタ刃を用い
て離型紙の裏側より表面基材のみを残して離型紙および
粘着剤層を切断する方法である。In the second method, a pressure-sensitive adhesive layer is formed on one side of a release paper, a series of pressure-sensitive adhesive treatments for bonding the release paper and a surface base material are performed, and then the release is performed using a rotating circular slitter blade. This is a method of cutting the release paper and the pressure-sensitive adhesive layer while leaving only the surface substrate from the back side of the paper pattern.
ところが、この第１の製造方法では、先に用いられる
離型紙は剥がして廃棄されるので、無駄であるばかりで
なく、その後に他のスリットを入れた離型紙を貼り合わ
せるので、製造工程も多くなる不都合があった。However, in the first manufacturing method, since the release paper used earlier is peeled off and discarded, it is not only wasteful, but also the release paper with another slit is attached afterwards, so that many manufacturing steps are required. There was an inconvenience.
また、第２の製造方法では、表面基材の厚み精度の不
均一により、表面基材まで切断したり、離型紙に切り残
しが生じるなどの不都合があった。In addition, the second manufacturing method has disadvantages such as cutting to the surface base material and leaving uncut in the release paper due to uneven thickness accuracy of the surface base material.
この第１の製造方法や第２の製造方法の不都合を解消
するための第３の製造方法として、長さ方向に走行する
帯状離型紙の片面に粘着剤を塗布し、乾燥処理して粘着
剤層を形成し、この粘着剤層を有する帯状離型紙に回転
する円形スリッタ刃を用いて長さ方向にスリットを入
れ、このスリットを入れた帯状離型紙の粘着剤層上に表
面基材を貼り合わせる方法に想到した。As a third manufacturing method for solving the inconvenience of the first manufacturing method and the second manufacturing method, an adhesive is applied to one surface of a strip-shaped release paper running in a longitudinal direction, and dried to perform an adhesive. A layer is formed, slits are made in the length direction using a rotating circular slitter blade on the band-shaped release paper having the pressure-sensitive adhesive layer, and a surface substrate is attached on the pressure-sensitive adhesive layer of the band-shaped release paper with the slits. I came up with a way to match.
ところが、この第３の製造方法では、円形スリッタ刃
を用いてスリットを入れる離型紙の片面に粘着剤層が露
出しているので、この粘着剤がスリッタ刃の外周に付着
して切れ味を悪くし、また、スリッタ刃に付着した粘着
剤の一部が逆に離型紙側に不規則に転写して汚損する不
都合があり、この不都合を解消しないかぎり実用化は困
難である。However, in the third manufacturing method, since the adhesive layer is exposed on one side of the release paper in which a slit is formed by using a circular slitter blade, the adhesive adheres to the outer periphery of the slitter blade, and the sharpness deteriorates. In addition, there is a disadvantage that a part of the adhesive adhered to the slitter blade is transferred irregularly to the release paper side and is contaminated, and practical use is difficult unless this disadvantage is solved.
そこで、この発明は、上記の第１の製造方法のように
離型紙の無駄が生ぜず、第２の製造方法のように表面基
材まで切断したり、離型紙に切り残しが生じる不都合が
ない第３の製造方法を改良して、粘着剤がスリッタ刃の
外周に付着して切れ味を悪くしたり、離型紙側に不規則

る。Therefore, the present invention does not cause the waste of the release paper as in the first manufacturing method described above, and does not cause inconvenience of cutting to the surface base material or leaving uncut in the release paper as in the second manufacturing method. It is an object of the present invention to improve the third manufacturing method so as to eliminate the inconvenience that the adhesive adheres to the outer periphery of the slitter blade to make the sharpness worse, and that the adhesive is irregularly transferred to the release paper side and soiled.

製造方法であって、前記スリットを入れるとき、前記円
形スリッタ刃の外周に油剤を塗布しつつ前記スリットを
入れる構成を採用した。In order to solve the above-mentioned problem, the present invention applies a pressure-sensitive adhesive to one surface of a strip-shaped release paper running in a longitudinal direction, forms a pressure-sensitive adhesive layer by drying treatment, and forms a strip-shaped release having the pressure-sensitive adhesive layer. A slit is made in the length direction by using a circular slitter blade rotating on the pattern paper, and a surface substrate is stuck on the pressure-sensitive adhesive layer of the strip-shaped release paper containing the slit, a method for producing a laminated paper having slits, When the slit is formed, a configuration is adopted in which the slit is formed while applying an oil agent to the outer periphery of the circular slitter blade.

とにより、離型紙にスリットを形成した積層紙を得る。When slitting the release paper having an adhesive layer, since a slit is formed in the portion of the strip-shaped release paper having the adhesive layer while applying an oil agent to the outer periphery of the circular slitter blade,
The adhesive does not adhere to the slitter blade. Thereafter, a surface substrate is stuck to the pressure-sensitive adhesive layer of the release paper having the slit, thereby obtaining a laminated paper in which the slit is formed in the release paper.
