Paper Making Clothing Single Layer Press Felt

Press Felt

Paper machine felt is an important consumption material in papermaking industry. It is mainly used in fourdrinier paper machine, cylinder paper machine, paperboard machine to transfer wet paper and dehydration. 

Press felt is the medium of wet paper dehydration. Based on the felt, it drives the guide roll, undertake the traction of the paper machine and the leveling effect of the paper surface. 

Structure

Press felt can be devided in to single layer felt, double layer felt and triple layer felt according to the weight and machine speed. 

The common synthetic fibers in the fiber layer mainly include nylon staple fiber, polyester staple fiber and other fiber raw materials; the staple fibers with the same or different thickness are laid in layers on the bottom net, and then The bottom mesh layer and fiber layer are processed by needling, heat setting and other special post finishing processes to make BOM felt.

The press felt needs to provide the following functions: dehydration, smoothness and runnability. In recent years, larger and faster paper machines require press felts with higher consistency and quality. 

Parameters

Installation of felt 

01 Keep the felt clean to prevent oil from sticking to the felt.
02 Before the felt is flattened on each roll, it is not allowed to drop the top press roll, couch roll or support roll. Never pressurize the press roll until the paper machine is running normally.
03 When the felt is running slowly until it is running well, moisten the felt evenly with water until the water is saturated, then adjust the tension to stretch the felts to the optimum length, width and dehydration condition.
04 There shall be sufficient gap between the spoke and the shaft sleeve or between the spoke and the spoke to make the felt easy to cover and avoid pulling the felt in through the gap.
05 Before starting the machine, check whether there are foreign matters on the top and bottom of the felt, as well as pressing and auxiliary devices.
06 The running direction of the felt on the paper machine shall be marked by the arrow on the felt surface.
