Different single-sided machines require different pressure and glue gap Settings, and the best use guide is from the manual and trainer provided by the supplier. However, a general principle is to apply the minimum pressure between the corrugated roll and the pressure roll, to be consistent with the good corrugated type and the new adhesive forming. The ideal pressure setting is determined by the shape and thickness of the paper, and varies according to the width. Generally, the better the condition of the paper and the higher the temperature of the roll, the less pressure is required. At the same time, the smaller pressure also helps to reduce the damage to paper and prolong the service life of the corrugated roller. According to the condition of corrugated paper, reduce the use of pretreatment steam as much as possible. However, a moderate amount of steam can help the paper pass through the corrugated roller to the overpass.
Similarly, the tension of the corrugated core paper that reaches the single-sided machine should be controlled to the minimum state, so as to avoid the appearance of folding or rolling on the paper. Ideally, the core paper will enter the compaction area under the driving force of the roller's overspeed.
The clearance of the roller in the gluing unit is very important. These intervals include the gap between the squeegee and the upper rubber roller and the gap between the rubber roller and the corrugated roller. The former determines the upper glue thickness of the lenticular part; The latter should be set according to the thickness of the paper, slightly higher than the paper, and also to prevent the friction between the metal caused by the stop of the machine (such as the rupture of the paper). Obviously, as long as the rollers are not parallel, it will make the glue uneven, and then lead to cardboard warping.
