The nature of the PET high-temperature resistant adhesive tape is also the adhesive tape, and except the difference of the components of the material, the production and manufacturing processes of the PET high-temperature resistant adhesive tape are basically not different; in the actual production process of the adhesive tape, the mixing preparation of the raw materials of the base material, the selection preparation of glue, the coating of the glue, the rewinding of the large adhesive tape mother roll, the slitting of the small adhesive tape mother roll and the like are involved, wherein in the slitting and forming processing process of the finished adhesive tape, two processing modes can be adopted, wherein one processing mode is that: cutting a winding pipe, namely cutting a very long round pipe into short pipes with the same width and size for winding the adhesive tape, then cutting the adhesive tape of the adhesive tape mother roll, and finally winding each cut adhesive tape on each short pipe one by one; the second step is as follows: rewinding the large adhesive tape parent roll according to the length of the adhesive tape finished product so as to rewind the adhesive tape parent roll into small rolls, and then directly slitting the small adhesive tape parent roll according to the width of the adhesive tape finished product; in summary, the following problems mainly exist in the two processing methods:

1) when the first method is adopted for processing, the long winding pipe needs to be pre-cut in advance and then wound one by one, and the end pipe for winding needs to be sleeved and accurately positioned through pipe pulling equipment during actual operation, so that the whole operation process is complicated;

2) when the second method is adopted for processing, compared with the first method, although the operation of pre-cutting the winding pipe is omitted, the method mainly adopts the method of cutting the small adhesive tape mother roll section by section one by one in the process of directly cutting the small adhesive tape mother roll, the time consumption for cutting the single small adhesive tape mother roll is too long, and the processing efficiency is lower.
