摘要： A wet paper web transfer belt comprises a base body, a wet paper web side layer, and a machine side layer. The wet paper web side layer is formed of a high molecular weight elastic section, and fibers and filler particles are exposed at its surface. The fibers and filler particles are exposed in the form of an island-sea structure comprising islands section where the fibers are exposed, and a sea section where the filler particles are exposed. The fibers and the filler particles, both exposed at the wet paper web side layer, hold water at different times in the papermaking process as the wet paper web moves out of the press part of the papermaking machine.

摘要： 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.

摘要： A belt for a shoe-press of a paper machine having water drain grooves which are resistant to the occurrence of cracks in side walls of the water drain grooves. The surface condition of the water drain grooves side wall is arranged to be a pear-skin state having minute unevenness. Preferably the surface has an average surface roughness in a range of 10 to 50 micrometers in at least the upper two thirds of the total distance (depth) of the side walls of the water drain grooves between the top of the groove and the bottom thereof. The water drain grooves can be manufactured by rotary cutting blades disposed in a position in contact with a roll around which a belt is wound. The roll and the rotary cutting blades rotate simultaneously and a groove cutting device is shifted in the width direction of the belt so that water drain grooves are formed in the belt. The belt running speed on the roll is set at 2 to 20 m/min, preferably 5 to 15 m/min, and rotation speed of the rotary cutting blades is set at 1,000 to 8,000 rpm.
