Provided is a paper-making machine belt (or a paper-making shoe-press belt), which is excellent in a wet-web water-squeezing property, which is stable in a paper quality (e.g., wet-web smoothness or marking property), and which has little damage (e.g., cracking or wear) of the outer circumference of the belt being used. The paper-making shoe-press belt carries a felt for accepting the squeezed water from the wet-web and has draining grooves extended in the felt-side surface. The paper-making shoe-press belt is characterized in that the draining grooves extended in the felt-side surface have at least two kinds of different groove shapes in the transverse direction (or the CMD direction) of the paper-making machine. The groove shape enables the grooves of two continuous and discontinuous kinds to share the functions thereby to satisfy the improvements in the drainage and in the paper quality and the wet-web surface smoothness at the same time.
A shoe press belt for papermaking carrying a felt which absorbs water squeezed from a wet paper web, wherein two or more water drain grooves extend in a machine running direction (MD direction) in a felt side surface of said shoe press belt for papermaking and wherein said two or more water drain grooves include continuous grooves and discontinuous grooves, and the continuous grooves and the discontinuous grooves are substantially provided in alternating parallel rows.
