Background

The stacking machine is mainly arranged at the back of a rotary press for books and periodicals and newspapers, receives single portions of the books and newspapers which are transmitted from a wheel turning page machine after printing, and finishes the functions of counting and stacking into bundles (200-250 portions) on the stacking. At present, the thickness of paper printed on one production line of a rotary press in China is different from 1 to 6, and the thickness of a single paper cut by the rotary folding machine is different from 4 to 24 paper. The thickness of each sheet is from 0.06 to 0.43 mm, so that the thickness of a single part is from 0.24 to 10.32 mm, and the thickness changes greatly.
