PROBLEM TO BE SOLVED: To provide a leader cloth for pulling a belt for papermaking onto a paper machine, in a shape in which the tension is uniformly dispersed and there is no portion with the tensile force unapplied.;SOLUTION: The leader cloth is used for pulling the belt onto the paper machine and laying the same onto rolls. The configuration of the leader cloth is formed by an apex portion, a base portion, and right and left side edge portions connecting between each end portion of the base portion and the apex portion, and has a chevron-like shape substantially symmetrical with respect to a perpendicular line dropped from the center of the apex portion to the base portion as the axis of symmetry, and the left side edge portion is a curved line residing between two curved lines expressed by the following quadratic equation (1) and the following cubic equation (2), with respect to the width direction x and the longitudinal direction y; and the right side edge portion is a curved line substantially symmetrical with respect to the left side edge portion: y=(b/a2)x2 (1) and y=(b/a3)x3 (2) (In formula (1) and (2), (a) is a distance in width direction between the end of base portion and the end of apex portion; (b) is a distance between the base portion and the apex portion).;COPYRIGHT: (C)2006,JPO&NCIPI
