Among them, wet method copy paper making machines are divided into long-wire copy paper making machines, clamped-wire copy paper making machines, and inclined-wire copy paper making machines. The long-wire copy paper making machines involve a dehumidification step. When producing paper, the long-wire copy paper making machines use highly hydrated sticky chemical wood pulp obtained by a semi-free and semi-sticky pulping method. Its papermaking is characterized by high temperature of the paper material on the wire and difficult dehydration of the wire.
