本発明は、板類に貼りつけたフィルムの、板類側縁より
はみ出した部分を板類裏面に折返す折曲げ方法に係るも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of folding a film attached to a board, in which a portion of the film protruding from the side edge of the board is folded back onto the back surface of the board.
基板又は主テープにフィルムを貼付けると共にフィルム
の側縁を一部はみ出させてこのはみ出した部分を裏面側
に折返す方法として、その進行方向に対し回転軸線が９
０°以上の傾きとなす円錐形又は截頭円錐形のロールを
フィルム折返し面の方に配設したものがある（特開昭５
０−１０５７８０号）。A method of attaching a film to a substrate or main tape, making a part of the side edge of the film protrude, and then folding this protruding part to the back side is a method in which the rotation axis is 9
There is a roll in which a conical or truncated conical roll with an inclination of 0° or more is disposed toward the film folding surface (Japanese Patent Laid-Open No. 5
0-105780).
ところで上記従来の方法では折返したテープ縁を中央側
に引付ける作用を有するがロールの配設位置がフィルム
の折返し面にあることとで折返した部分に皺が発生する
という欠点がある。By the way, although the conventional method described above has the effect of attracting the folded edge of the tape toward the center, it has the disadvantage that wrinkles occur in the folded portion because the roll is disposed on the folded surface of the film.
この発明は上記従来の方法の欠点を解決したもので、そ
の目的とするところは折返した部分に皺を生じることな
き折返し法とするにある。This invention solves the above-mentioned drawbacks of the conventional methods, and its purpose is to provide a folding method that does not cause wrinkles in the folded portion.
この発明は、ロールをつゾみ形とし、且つ板類側縁が、
前記ロールの中央小径部に入り込む接触とすると共に前
記ロールの板類の流れ方向手前側が板類側縁より上位と
なるようにロールを傾斜させたことを特徴とする。In this invention, the roll has a tufted shape, and the side edge of the plate is
It is characterized in that the roll is inclined so that the contact enters into the center small diameter part of the roll and the front side of the roll in the flow direction of the plates is higher than the side edge of the plates.
以下本発明の実施例を図面に基いて説明すれば、１は表
面にフィルム２を貼りつけた板体であり、板体の側縁に
はフィルムの側縁ａがはみ出している。Embodiments of the present invention will be described below with reference to the drawings. Reference numeral 1 is a plate with a film 2 pasted on its surface, and a side edge a of the film protrudes from the side edge of the plate.
このはみ出した側縁ａは板体１の裏面に折曲げ貼りつけ
てしまうのであるがその方法は板体１を水平位で、且つ
フィルムのはみ出し側縁ａが板体１の側方になるように
して台（図示省略）上を走行させる。This protruding side edge a is bent and pasted on the back side of the plate 1, but the method is to hold the plate 1 in a horizontal position and make sure that the protruding side edge a of the film is on the side of the plate 1. and run on a platform (not shown).
そして板体１の側縁には之と向きが並行のつゾみ形ロー
ル３が配置され、且つ板体の側縁をロールの中央小径部
に入り込ませ接触させると共に板体の流れ方向に於てロ
ール３の手前側を板体１より上位になるように傾斜させ
ておくのである。On the side edge of the plate body 1, a tsuzo-shaped roll 3 is arranged parallel to the plate body 1, and the side edge of the plate body is inserted into the center narrow diameter part of the roll and brought into contact with the roll, and at the same time, the side edge of the plate body is placed in the flow direction of the plate body. The front side of the roll 3 is inclined so that it is higher than the plate 1.
ロール３の軸方向の長さはフィルム２のはみ出し側縁ａ
が折曲げられるときフィルムに皺が生じない最小長さに
しておく。The length of the roll 3 in the axial direction is the protruding side edge a of the film 2.
The length should be the minimum that will not cause wrinkles in the film when it is folded.
； この状態で板体１を矢印の方向に走行せしめると、
第３回者図に理解できるようにフィルムのはみ出し側縁
ａが順次折曲げられる。; When the plate 1 is moved in the direction of the arrow in this state,
As can be seen in the third person's drawing, the protruding side edges a of the film are sequentially folded.
第３図イ乃至へは第１図のロール３の符号イ乃至へに対
応する部分に於けるフィルム２のはみ出、し側縁ａの折
曲げられて行く状態を順に示しており、はじめは板体１

ルムを板体の側面に圧着し、次いで板体より下方にある
ロールの大径部がフィルムを板体側縁の下部隅角に向は
押圧し板体裏面に折返えさせて行くのである。3A to 3A to 3D show in sequence the state in which the film 2 protrudes from the parts corresponding to the numbers A to I of the roll 3 in FIG. 1, and the side edge a is bent. body 1
The large diameter part of the roll located higher up presses the side edge of the film toward the upper corner of the side edge of the plate, bends it downward, and gradually strengthens the bending. The film is pressed against the side surface of the plate, and then the large-diameter portion of the roll located below the plate presses the film against the lower corner of the side edge of the plate, causing it to be folded back onto the back surface of the plate.
第３図ト図は板体１がロール３より離れたところで板体
裏面を平ロール４で押圧しフィルムの縁を板体裏面に密
着せしめるのである。In FIG. 3, when the plate 1 is separated from the roll 3, the back surface of the plate is pressed by a flat roll 4 to bring the edge of the film into close contact with the back surface of the plate.
尚ロール３は必ずしも図示の如き１個のものに限らず、
このロールを複数個に分割して同一軸上にセットするこ
ともでき、又板体１の厚みが犬になればロール３の傾斜
を之に合わせて急傾斜となるように傾斜角を変更するも
のとする。Note that the roll 3 is not necessarily limited to one roll as shown in the figure.
This roll can be divided into multiple pieces and set on the same axis, and if the thickness of the plate 1 becomes too thick, the inclination angle of the roll 3 can be changed to make it steeper. shall be taken as a thing.
この発明は上記したようなものであり、この方法はロー

傾斜させたものであるから、その折曲げ過程が段階的と
なってきわめて円滑になり、皺の発生もなく美麗な仕上
りになるという効果がある。This invention is as described above, and this method uses a roll having a tufted shape, and the side edges of the plates are brought into contact with the center small diameter part of the roll, and the front side of the roll in the flow direction of the plates is brought into contact with the roll. Since the roll is tilted so that it is above the side edge of the board, the bending process is gradual and extremely smooth, resulting in a beautiful finish with no wrinkles.
尚ロールはゴムロール・ブラシロール・フェルトロール
等を適宜選択使用し得る。As the roll, rubber rolls, brush rolls, felt rolls, etc. can be appropriately selected and used.
