Description

Technical Field

During this process, the discharge plate 3 corresponds to the external feeding device, and the other end of the discharge plate corresponds to the receiving device, and then the external control system controls the heating elements on the upper bending component 9 and the lower bending component 10 to make the bending part 93 reach a certain temperature; when starting to use a polytetrafluoroethylene filter material upper and lower knife staggered bending device: the feeding device will need to bend The bent polytetrafluoroethylene filter paper is transported to the discharge plate 3.
