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 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 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 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 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 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.
