The method and device for checking quality of rod-like products (R, R) for the tobacco industry, wherein the steps are performed of moving rod-like products (R, R) placed in a transport socket (4) of a conveyor (2) along an audit trail (P), checking the quality of a rod-like products (R, R) with a scanning device (5) placed on the audit trail (P), characterized further by rotating the rod-like product (R, R) placed in the transport socket (4), during the step of checking the quality of rod-like products (R, R), using at least one track (7) interacting with a lateral surface (6) of the rod-like products (R, R).

Variable-capacity store for cylindrical articles of the tobacco processing industry; the store comprises a conveying assembly comprising a first conveyor having a substantially helical shape; a second conveyor having a substantially helical shape and arranged above the first conveyor; and a linear transfer conveyor, which is adapted to convey the articles from the first conveyor to the second conveyor, having a variable length and, by extending and shortening, changes the area of the first conveyor from which it picks up the articles and the area of the second conveyor to which it feeds the articles, thus varying the capacity of the store.
