The method comprises the following operative phases: - printing designs or similar with rotochalcographic and flexographic machines, on at least a strip of paper, and forming a plurality of perforations thereon to obtain a ribbon; - recoiling of each ribbon thus obtained and placing of a number of coils on a support frame; - unrolling pairs of ribbons by means of entrainment rolls; - superimposing a number of pairs of ribbons by means of a return roll to form a continuous pack of ribbons; - feeding said continuous pack of ribbons to an intermittent press by means of a belt; - shearing, forming and stacking the produced cups, equal in number to the number of the superimposed ribbons. |
