【発明の詳細な説明】
本発明はカツターを用いず、単に指で引き千切
るだけで切断でき、しかも強度の低下が極めて少
ない易切断巻回粘着テープに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an easy-to-cut wound adhesive tape that can be cut by simply tearing it with fingers without using a cutter, and which exhibits extremely little loss in strength.
一般に粘着テープ、特にポリプロピレン、ポリ
エチレン、ポリ塩化ビニル等のプラスチツクから
なる粘着テープを必要量巻出し、切断して使用す
るには刃物を必要とする。しかし常に鋏やナイフ
が傍にあるとは限らないため鋸歯を有するカツタ
ーが巻回した粘着テープに備えている。この鋸歯
が往々にして手指に触れ、怪我の原因となつた。 In general, adhesive tapes, especially adhesive tapes made of plastics such as polypropylene, polyethylene, polyvinyl chloride, etc., require a knife to unwind the required amount and cut them for use. However, since scissors and knives are not always nearby, a cutter with serrations is equipped with a wound adhesive tape. These serrations often touched hands and fingers, causing injury.
更に鋸歯の場合、切断線がぎざぎざの凹凸とな
るため、次の巻出時にテープの縦切れを起し易
く、巻出不良の大きな原因でもあつた。 Furthermore, in the case of serrations, the cutting line has jagged irregularities, which tends to cause the tape to break vertically during the next unwinding, which is a major cause of unwinding failures.
カツターを用いず、手指の力だけで切断できる
粘着テープとしては薄いフイルムを用いること、
横延伸した素材を用いること等が提案されている
が、薄いフイルムは当然に強度が低下し、補強効
果が低下する。そのため裏面を紙で補強したもの
もあるが、厚地プラスチツクフイルムの強度には
及ばない。 Use a thin film as the adhesive tape that can be cut with just the power of your fingers without using a cutter.
Although it has been proposed to use a laterally stretched material, thin films naturally have lower strength and a lower reinforcing effect. For this reason, some have paper reinforced on the back, but this is not as strong as thick plastic film.
また、プラスチツクテープの全面をサンドブラ
スト等により梨地加工し鉛筆等の筆記具で任意の
文字や記号を記入できるテープが販売されてい
る。このテープは梨地の窪み内に、筆記用素材が
嵌入し補捉されて筆記できるものであるが、その
反面非常に弱く、補強効果を期待できず任意の文
字、記号を付したラベルを貼着する用途に使用さ
れるにすぎない。 There are also plastic tapes on sale that have a satin finish on the entire surface by sandblasting or the like and allow arbitrary characters or symbols to be written on them with a writing instrument such as a pencil. This tape allows writing material to be inserted into the depressions of the satin material and captured, but on the other hand, it is very weak and cannot be expected to have a reinforcing effect, so labels with arbitrary characters and symbols can be attached. It is only used for purposes.
手指の力だけで切断できる粘着テープとしては
予めテープの側縁に多数の短い切込みを刻設する

法によると主としてテープの長さ方向又は厚み方
向に向かつて過擦傷が設けられるため、手指切断
のために有効な横断方向に設けられず充分な切断
効果が得られなかつた。 For adhesive tapes that can be cut using only the force of the fingers, a method is known in which a large number of short cuts are made in advance on the side edges of the tape. For example, Tokuko Sho 48-38462
No. 53-19448 discloses an adhesive tape obtained by cutting into a tape shape with a rotary knife having a sharpened blade edge cut with coarse grains to a minute serration state. has been done. However, according to this method, the scratches are mainly provided along the length or thickness direction of the tape, and therefore cannot be provided in the transverse direction, which is effective for cutting fingers, and a sufficient cutting effect cannot be obtained.

が開示されている。しかしこの方法によつても、
製品粘着テープの側縁となるべき部位に一本宛傷
を設け、テープ幅に切断し次いで巻回する手間を
要し、工業的に採用できる方法ではなかつた。 Furthermore, in Japanese Patent Application Laid-open No. 53-19448, the film before slitting is tightly pinched between a roughened metal roller and a rubber roller at appropriate width intervals to form cracks, and then the film is slit at the cracks to form a tape. A method is disclosed. However, even with this method,
This method cannot be adopted industrially because it requires the labor of making a single scar on the side edge of the product adhesive tape, cutting it to the width of the tape, and then winding it.

は過擦するのみで加工することができる。 An object of the present invention is to provide a wound adhesive tape which can be cut by hand with fingers without substantially reducing the strength of the adhesive tape through an extremely simple process of damaging the adhesive tape all at once while being wound. In other words, these are not scratches caused by a knife that weakens the strength of the adhesive tape, but are merely press scratches or scratches that are transferred from the abrasive grain surface, and are scattered in countless numbers in the transverse direction of the tape to be cut. The ring surface (hereinafter referred to as slit surface), which is a set of longitudinal cut surfaces of the ring surface, can be processed by simply pressing or rubbing an abrasive surface.

それがない。 According to the present invention, applying strain force to the edge of the tape by applying force with the fingertips creates the first notch where tearing begins, and thereafter this tearing is facilitated due to the low tear propagation strength of the plastic. It can propagate to the other end and be cut, and there is no risk of the adhesive adhering to the abrasive grain surface during processing and causing clogging of the abrasive grain surface.

らさない。 To process the scratches of the present invention, the slit surface of the wound adhesive tape is pressed with a hard abrasive surface such as an abrasive surface or a metal surface to which an abrasive surface has been transferred, or in some cases, excessive rubbing is performed. It's okay. The scratches that should be made on the adhesive tape are not deep enough to reduce the strength of the tape, nor are they sharp scratches caused by a knife, but are extremely shallow and can be considered as mere surface roughening. Because the slit surface was pressed or rubbed with an abrasive surface, the scratches were irregularly scattered along the side edge line of the tape, and most of the large scratches were formed in the transverse direction of the tape, causing unwanted damage. Not only is there no risk of cracks running in the direction, but the work is extremely efficient. Furthermore, since the scratches are provided on the slit surface that has already been wound, a considerable portion of the scratches straddles two or more wound adhesive tape layers, depending on the thickness of the tape and the roughness of the abrasive grain surface. The roughness of the scratches varies depending on the thickness and type of adhesive tape to be processed. Generally, plastic films have a high tensile strength, but when a flaw occurs in one place, the flaw tends to propagate easily with a small amount of force. Therefore, the flaw according to the present invention is such that it can be spread by pinching the edge of the tape and applying strain force with fingers, that is, it has a tear initiation effect. Normally, when unwinding or using tape,
After pasting, a large force is not locally concentrated on the edge of the tape, so if this degree of damage occurs, the strength will decrease, which can lead to practical problems such as the tape being cut mid-way when being pulled out or used. does not bring about

るため、0.2cmあたり１個以上の傷を要する。 The number of scratches with tear initiation effect is 0.2 at the side edge length.
It is desirable that there be one or more per cm. Since these scratches are small, strain force from hands and fingers can be applied without recognizing the scratches, and if the number of scratches is smaller than this, even if strain force is applied to an area distant from the scratches, the tear initiation effect will be exerted. In order to avoid this, it is necessary to make one or more scratches per 0.2 cm.

Guided by the wound, without running away,
Can be cut precisely at right angles to the longitudinal direction.
