Improvements in the manufacture of discs for polishing machines, characterized in that each plane in a circular crown, whose superposition with similar ones constitutes the disc, is obtained from a single piece of textile material cut substantially in an elongated rectangular pattern, its cutting being carried out, preferably , in the direction of the intersecting points of the warp and weft threads, and staggered, transverse and uniformly spaced fold lines are indicated which, in each fold to be formed, affect a plot in an isosceles triangle whose height is oriented in the direction of the longitudinal median line of the fabric, line that is also indicated as a line of future fold, the width of the piece being approximately equal to twice the width of the circular crown to be obtained from the expressed piece, while its length is equal to the circumference interior of the aforementioned crown, plus the product of the height of the mentioned triangle layouts isosceles by the number of these triangles, being in turn this height inversely proportional to the radius of curvature of said crown, within a determined staggering of such bends.
