Problems solved by technology

[0006] On the other hand, in the case of a so-called non-stretched film that is not oriented, since there is no rigidity on the film, as described above, when the subsequent resin film is connected to the preceding resin film, it is used as the film cutting mechanism. When the film cutter touches a point of the film, it immediately breaks in pieces and produces film fragments
The film fragments adhere to the bonded resin film and are carried into the next processing step, making it impossible to perform stable processing.

Abstract

A connection method and connection apparatus for connecting long belt-shaped non-oriented resin films that are continuously advanced. A leading resin film and a trailing resin film can be connected while processing in a following step is continuously performed. The tip end of a trailing resin film (22) is joined and connected to a leading resin film (11), and then a portion, immediately after the connected position, of the leading resin film is heated to a predetermined temperature range and cut.

Description

technical field [0001] The present invention relates to a connecting method and a connecting device of continuously running elongated strip-shaped resin films. Background technique [0002] Most of the resin films used as various tapes and packaging materials are continuously produced in the form of long tapes in the manufacturing process, cut into appropriate widths, wound into coils with appropriate lengths, and output to In the next process, the long tape-shaped resin film wound into a coil is processed according to various uses. In the processing step, the long tape-shaped resin film wound into a coil is continuously unwound. Processed and consumed. In order not to interrupt the processing process, it is necessary to connect to the next coil of resin film before the coil of resin film is unwound and completely consumed. [0003] The connection of the preceding resin film and the following resin film, such as Figure 6-8 Proceed as shown. That is, if Figure 6 As show...
