A variable-capacity store for articles of the tobacco processing industry, in particular substantially cylindrical articles; the store comprises a conveying system to convey the articles from an input station to an output station along a path (P) with a variable length; the conveying system comprises at least two conveying assemblies , each of which is adapted to convey the articles along a respective segment of the path (P) and comprises a respective first conveyor and a respective second conveyor ; and at least one movement assembly to move at least one between the first conveyor and the second conveyor relative to one another between a first configuration, in which the first conveyor and the second conveyor at least partially overlap each other, and a second configuration, in which the second conveyor has a first active portion , which is staggered with respect to the first conveyor , going through at least one intermediate configuration, in which the first conveyor and the second conveyor at least partially overlap each other; the variable-capacity store being characterized in that in the intermediate configuration the second conveyor has a second active portion , which is staggered with respect to the first conveyor and is shorter than the first active portion ; and in that in the first configuration, said segment of the path (P) has a first length; in the second configuration, said segment extends along at least part of the first conveyor and at least part of the first active portion and has a second length greater than the first length; in the intermediate configuration, said segment extends along at least part of the first conveyor and at least part of the second active portion and has a third length greater than the first length and smaller than the second length. the conveying system comprises at least two conveying assemblies , each of which is adapted to convey the articles along a respective segment of the path (P) and comprises a respective first conveyor and a respective second conveyor ; and at least one movement assembly to move at least one between the first conveyor and the second conveyor relative to one another between a first configuration, in which the first conveyor and the second conveyor at least partially overlap each other, and a second configuration, in which the second conveyor has a first active portion , which is staggered with respect to the first conveyor , going through at least one intermediate configuration, in which the first conveyor and the second conveyor at least partially overlap each other; the variable-capacity store being characterized in that in the intermediate configuration the second conveyor has a second active portion , which is staggered with respect to the first conveyor and is shorter than the first active portion ; and in that in the first configuration, said segment of the path (P) has a first length; in the second configuration, said segment extends along at least part of the first conveyor and at least part of the first active portion and has a second length greater than the first length; in the intermediate configuration, said segment extends along at least part of the first conveyor and at least part of the second active portion and has a third length greater than the first length and smaller than the second length. <EOS>
