Features
1 Glue dispensing and paper folding are both performed in the identical machine. After paper collected, the filter paper is conversed by longer conveyer belt, which helps to solidify the hot melt and get needed length.
2 The main frame and conveying mechanism are controlled by frequency converter which is easy to adjust.
3 The filter material’s journey after glued can be regulated among certain scopes. Which avails the dryness and humidity of hot melt and good for firmly folded.
4 Set xix pairs of rollers together in a round table, which is easier to change and apply to produce in different specifications.
5 Melt quickly, the glue dispensing quantity can be easily controlled by frequency converter.
6 High productive efficiency, good smoothness.
