Abstract

본 발명은 비디오용 필름이나 오디오용 필름등 각종 필름을 권취할 때 사용하는 지관의 제조방법에 관한 것으로, 1차로 제조된 지관의 표면을 1차 열처리한 다음 그 표면을 연마하여 가공하고, 2차로 양측이 경사지게 절단된 보조지폐를 접착제를 도포하여 지관의 표면에 부착하며, 3차로 지관의 표면에 왁스를 도포하여 건조한 다음, 지관의 내부에 고정봉을 삽입한 상태에서 2차 열처리하고, 4차로 지관의 양측 끝부분을 절단한 다음 절단된 부분에 수지를 코팅하며, 5차로 양측이 절단된 지관의 절단된 부분을 내경과 외경을 경사지게 압착 성형하여서 된 것으로서, 구조가 간단하여 제작이 용이하고 지관의 표면에 보조지폐가 권취되어 있기 때문에 필름이 파손되는 것을 방지할 수가 있으며, 또한 지관의 표면에 보조지폐를 권취한 다음 연마하고 다시 그 표면에 왁스를 도포한 다음 지관의 내부에 고정봉을 삽입한 상태에서 2차 열처리를 하기 때문에 지관의 휘는 것을 방지하고 이로 인하여 제품의 품질을 높이고 불량의 발생을 방지하므로서 원자재의 낭비와 인건비의 낭비 및 작업시간을 단축할 수가 있으며 제품을 대량생산 할수가 있는 유용한 발명인 것이다.The present invention relates to a method for manufacturing a paper tube used when winding various films such as a video film or an audio film. The surface of the first manufactured paper tube is subjected to a first heat treatment, and then the surface is polished and processed. Apply the adhesive to the surface of the paper pipe by applying an adhesive to the surface of the paper pipe, and apply wax on the surface of the paper pipe to dry it, then heat-treat it with a fixed rod inserted inside the paper pipe, and After cutting both ends of the branch pipe, resin is coated on the cut part, and the cut part of the branch pipe cut on both sides in 5th order is formed by obliquely pressing the inner diameter and the outer diameter, and the structure is simple. Since the auxiliary paper is wound on the surface of the paper, the film can be prevented from being damaged. Also, after the auxiliary paper is wound on the surface of the paper pipe, it is ground and polished again. Since wax is applied to the surface and the secondary heat treatment is performed while the fixing rod is inserted into the inside of the paper pipe, it prevents the paper pipe from bending, thereby improving the quality of the product and preventing the occurrence of defects, thereby reducing the waste of raw materials and labor costs. It is a useful invention that can reduce waste and work time and can mass produce products.

Claims

In the known paper tube manufactured by the shaping, the primary paper tube (1) manufactured first is heat-treated, and then the surface thereof is polished and processed. 2) is applied to the surface of the branch pipe (1) by applying an adhesive (5), and in this state the surface of the secondary bank (2) is second polished, and the wax (6) is applied to the surface of the branch pipe (3) After drying, the second heat treatment was performed while the fixing rod (3) was inserted into the inside of the branch pipe, and both ends of the branch pipe (4) were cut in four times, and then the resin (4) was coated on the cut portion. A method for producing a paper pipe, characterized in that the cut portions of the paper pipe (1) cut on both sides are formed by pressing the inner and outer diameters inclinedly.

A branch pipe, characterized in that the secondary bank (2) is attached to the entire surface of the branch pipe (1) so that the spiral line of the branch pipe (1) does not protrude.

The paper pipe according to claim 2, wherein both side surfaces of the auxiliary bank (2) are inclinedly cut in one direction to form an inclined cutting surface (7) and attached to abut the inclined cutting surface (7).
