Cylinder paper machine has a forming part of cylinder cage or net cage which is cylinder shaped. Felt goes on the cylinder and get pulp applied on it to form paper. Fourdrinier paper machine's forming part do not have cylinder forming, it is a long flat felt conveyor part to get pulp applied on it to form paper.
The rest section of paper machine are almost the same, there are one or more yankees in the drying section. It dries the pulp on the felt quickly to form dried paper, and then get released from the yankee and rolled.
Difference in final produts:
Cylinder paper machine is mostly used for producing tissue paper, towel paper, sometimes printing paper. Fourdrinier paper machine is used for making all kinds of paper and the paper will have much better physical performence. The performence includes horizontal strength and vertical strength ratio, extensive ratio, printing performence, etc. And fourdeinier paper machine has much faster production speed.
While the paper from fourdrinier paper machine has much better performence, but the cost for setting up this machine is much higher. It can reaches two to three times of cylinder paper machine, thus cylinder paper machine is mostly used for making tissue paper and towel paper, because normally these paper don't need very good physical performence.
