Abstract
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.
