[0002] The forming cage used in the superforming papermaking machine, also called the cage or round mesh, is an important component of the papermaking process. This forming cage is a circular arc structure. Its main function is to dehydrate the pulp suspension from the headbox and help the paper web to form during the papermaking process. During the papermaking process, the fiber suspension passes through several baffles in the headbox and then enters the mesh slot in the forming area. Under the action of a certain liquid level difference, water enters the cage through the mesh of the cage and is pumped away, while the fibers remain on the mesh surface of the cage to form a fiber web, which is then consolidated to form a non-woven fabric.

The forming mesh cage is often supported only by the arc frame, so the compressive strength is relatively weak, and the arc frame and the mesh cage are not strong enough, so it takes a lot of time to repair. The forming mesh cage cannot withstand high temperatures and has poor flame retardant properties. Therefore, it is particularly important to design a forming mesh cage for a super-forming papermaking machine. Utility Model Content
