There are two main kinds of paper machine clothing: clothing for the wet and clothing for the dry end.

The paper machine clothing for the wet end is usually called the wire, because the first wires were made of woven wire. One of the first innovations of the woven wire was a staggered weave that eliminated the problems of wires hanging up or freezing in the suction boxes. Another important early innovation was the welded seam which replaced hand-woven seams. This eliminated the visible line created each time the seam made it way around the moving wire.

   

But wire is basically an inflexible material. If stretched, bent, or frayed, the anomalies remain in the wire and affect the look and consistency of the paper. Wire is also not very resilient and the older wires often broke.

The development of polyester forming fabric, or paper machine clothing which could stretching, made the higher speeds and increased productivity possible of today's paper machines. A paper making fabric usually lasts at least several months before maintenance is required.

Dry end clothing is usually made of felt. Felt is the fabric used to pick the wet stock off the wire. It also acts as a blotter, soaking up water, in the press section of the machine. The felt usually passes between a series of press rolls which squeeze out more water. This kind of felt can also be used in the multiple dryer section.
