There is a gap between the pressing rod 1051 and the supporting roller 4, which does not affect the transportation of the cardboard.

[0023] The working principle and use process of this utility model:

[0024] When the corrugated paperboard body 5 is transported and cut in the longitudinal cutting and creasing machine body 1, the corrugated paperboard body 5 is first cut by the thin knife on the longitudinal cutting roller frame 2;

[0025] The corrugated paperboard 5 is transported continuously after trimming, and the laser sensor 104 senses the trimmed paperboard;
