Paper threading system is an important part of papermaking equipment. It consists of threading rope, rope pulley and transmission device. It is mainly used for threading and transferring paper strips to the next working area.

Paper dryer cylinder refers to a machine used in papermaking machinery to continuously dry the paper blank after the pulp is formed. Dozens of drying cylinders are placed crosswise in a paper machine.

The main components of the dryer cylinder​ are steam joints and spoilers.Steam needs to be passed through the dryer cylinder, and the condensed water inside needs to be drained. But the drying cylinder is a rotating cylinder, so a special joint is needed to complete this task, that is, the steam joint.

The common problem of dryer cylinder​ is the wear of the dryer cylinder shaft head. Due to the high temperature and pressure of the drying cylinder during operation, the shaft head of the drying cylinder is prone to wear and tear, causing the equipment to fail to operate.

The dryer cylinder​ is a hollow cylinder made of cast iron with covers at both ends. It is composed of a cylinder body and cylinder heads at both ends. The outer diameter is usually 1000～3000mm. During operation, the conveyed paper will be dried by internal steam. Burned.
