    摘要： A papermaker's pressure belt for extended nip presses, which comprises a belt base formed of a strong woven fabric having high dimensional stability, a squeezing layer to be in contact with a wet fibrous web on an extended nip press, having a large void volume and formed of a compressible elastic and porous or cellular material, such as fibrous batt, sponge or a foam resin, and formed on one side of the belt base, and an impermeable layer impermeable to oil, formed on the other side of the belt base. The squeezing layer facilitates the separation of the fibrous web from the pressure belt, while the impermeable layer inhibits the permeation of the lubricant applied to the acting surface of the pressure shoe of the extended nip press through the pressure belt.

    摘要： A method for manufacturing a pressure belt for use with an extended nip press in a paper making machine. The belt is characterized by a base fabric formed of a synthetic fiber filament, and formed with a synthetic resin layer on each outer and inner peripheral side thereof. The outer peripheral side which becomes in contact with the felt is provided with a number of drain channels. In the method of manufacturing, a base fabric in the form of an endless belt is trained around a heating cylinder, guide rolls and stretching rolls. The outer peripheral surface of the base fabric is coated with a curable synthetic resin as the fabric is moved. The layer of synthetic resin is semi-cured by heating means including the heating cylinder. This process of coating and semi-curing is repeated until desired thickness of the resin layer is obtained. Drain channels are then formed in the semi-cured resin by an embossed roll whereupon the resin layer is cured and then ground to provide a desired thickness. The inner surface of the belt is then coated with resin in a similar manner to the coating of the exterior surface followed by curing and grinding to provide a uniform thickness to the finished pressure belt. Such a construction is advantageous, for example, in improving the travelling stability of the belt and the dewatering efficiency with a web of paper.
