Abstract
This aims to provide a paper making machine belt (a shoe press belt) having excellent wet squeezability but less damages (such as cracks or wear) of the outer periphery of a belt being used. The paper making shoe press belt includes drainage conduits extended in the felt-side surface thereof. The drainage conduits are discontinuous grooves, and are made semi-arcuate on at least one of the belt ends in a belt running direction (an MD direction).
