Brief Introduction Of The Working Proceure

Feed the paper roll into the Mill Roll Stand. In the Pre-heater, the paper roll is heated and its moistuure and
tension force are adjusted. The paper roll is pressed to a corrugated shape and fed with glue in the single
facer, and then it is agglutinated with another paper roll to form a piece of single face corrugated cardboard.
The conveying span bridge tidies and transports the single face cardboard to the muli-ply pre-heater for the
second pre-heat. The glue application machine puts glue on the sharp top of the single face corrugated car

-dboard before it is heating agglutinated with another paper roll in the double facer. After cooling formed in
the double facer.A piece of corrugated cardboard is made.According to the requipment of the order.The cor
-rugated cardboard is cut precisely in the slitter scorer and the cut-off. A piece of rectangle corrugated
cardboard is finished. After quantity counts and being piled up in the stacker, the finish cardboard can be
conveyed out. An entire working procedure of the production line is completed.
