摘要： This invention relates to a papermaking felt which makes it possible to increase the proportion of the base body thereby preventing flattening without costing extra production man-hour, and to maintain the functions such as the water drainage, wet paper smoothening capability, and wet paper web transport capability throughout its entire use period by. The papermaking felt composed of a base body and a batt fiber layer is characterized in that one or more thicknesses of endless base bodies are disposed on the felt back-face side and one or more thicknesses of open-ended base bodies is annularly wound not less than one turn on the felt front-face side.
