である。Detailed Description of the Invention 40 Object of the Invention The present invention is a method for cutting off unnecessary parts and sealing by heating a cutting blade for cutting off unnecessary parts at the end of a synthetic resin film for bag making, and using both warping and sealing. The purpose is to simplify the work.

係るものである。４け切刃２１の刃台を示す。0 Structure of the Invention As shown in the illustrative diagram, the present invention folds a printed film plain sheet A into two sheets while winding them up on a take-up roll L, and then inserts a blade at the starting end of the sealing position so that the two sheets are folded into a cylindrical shape. A cutting blade 2 with an electric heating 3 that forms a part into an arc-shaped body 2 is equipped on the front downward. 2I is cut into a tape shape on the outside, and the cutting edge 2ν
The sealing position remaining inside the cutting blade 21 is initially moved to the arc-shaped body 2, and the sealing position is integrally sealed by the heat of the cutting blade 2). The blade stand of the four cutting blades 21 is shown.

The two ends touching the outside of the cutting blade 2 (according to the glue removal operation, the inside of the cutting blade 2) move forward in the winding direction as one,
Since the cutting blade 2' is provided downward in the front, the integrated part
? It rises sequentially from the cut end and reaches the second part of the arc-shaped body with the second cutting edge.
A strong seal can be created by thickening the heat-fused seal.
その肉付けの度合いはシール部が弧形胴２全通過時間に
比例するので袋の大小や種類により切刃２ノの長さを適
寸にすればよい。何れＫしても継ぎ目は袋の折目である
から殊更に目立つことがなく、美麗な袋ができる。The degree of filling is proportional to the time the seal portion takes to pass through the arc-shaped barrel 2, so the length of the cutting blade 2 may be adjusted to an appropriate length depending on the size and type of the bag. In any case, since the seams are folds of the bag, they are not particularly noticeable, and a beautiful bag can be obtained.

汚州することがない。The cylindrical film formed by supplementary cutting is cut into the required dimensions 1.
Bags are made by sealing the bottom, but conventional synthetic resin film bags are made by printing the tube without cutting them into flat plates, which requires two printing steps on the front and back.
According to the present invention, bags are cut into flat plates, printed, and then sealed into cylinders, so bags can be made with the printed bag on the inside, so there is no wear or staining of the printing.
又、表面忙印刷する場合でも裏面に印刷する場合と同様

な発明である。In addition, even when printing on the front side, the design can be continuous on the top and bottom sides of the bag in the same way as when printing on the back side, and printing can be done in one process, reducing labor costs, etc. This is a beneficial invention. .
