    (54) Method and apparatus for temporarily accumulating an excess of a paper web


    (57) An apparatus for the temporary accumulation of a web (N) of material, which is continuously fed to means (201, 203) for the processing of the same web, is provided with transmission means (205, 207) which define the web trajectory, and means for accumulating the excess material. The means for accumulating the excess web comprise: an element (211) forming a slide surface for the web (N); and members (213; 215, 217) able to generate a pressure force between the web (N) and the slide surface. The apparatus is particularly suitable for its application in rewinders.
