Roller.So, produce desired multiple fiber web grade need number of different types technology production process line in it is necessary to
Change at least one of these rollers of processing equipment to adapt to the change of grade.The time that it consumes is very long, generally (replacing)
One roller at least wants 1.5-2 hour, and producing process line during this period must stop, and therefore produce and also will stop.
For example, when the fiber web applying glue to sheet lining or corrugated paper grade, using having based on being suitable to weight grade
The device of coating treated substance of soaking pit technology and the dress of the coating treated substance based on the film transfer technology being suitable to light grade
The sizing applicator type put, but due to for soaking pit technology hard roller and soft roller group (conjunction) will be favourable, and film transfer technology is then
Soft roller and soft roller group must be used, therefore can not obtain optimal sizing efficiency when using one group of roller.Generally every group of roller is also
Need different middle height (crowning).If this equipment is used for processing two grades of weight in shorter time interval,
Lead to each multiple roller of equipment needs and spare roll, and need repeatedly more roll change.
