A transport system of cylindrical products to be labelled, for transporting the products and for causing the products to transit at a device for applying labels which comprises supply means for supplying and applying a label on the products and abutting means for abutting the products on which the label has been applied, characterised in that it comprises a first conveyor means and a second conveyor means, wherein: the first conveyor means comprises pairs of support members (12, 13) for supporting the cylindrical products to be labelled and is predisposed and configured so as to have a conveyor portion along which the pairs of support members (12, 13) are moved according to an advancement direction so as to cause the pairs of support members (12, 13) to transit at the device for applying labels, the support members (12, 13) of each pair of support members being predisposed parallel to one another and mutually distanced so as to identify a free space between them, and which are conformed in such a way as to have respective V-shaped housings (120, 130) defining a seating for restingly receiving a corresponding cylindrical product to be labelled with the cylindrical product being arranged with the relative axis transversal with respect to the advancement direction so that the product transits with the cylindrical lateral surface thereof, or a portion of cylindrical lateral surface, below the device for applying the labels so that the supply means can supply and apply a label on a part of the cylindrical lateral surface or a portion of cylindrical lateral surface, the second conveyor means is a looped conveyor means having an upper branch and is arranged with respect to the first conveyor means in such a way that the upper branch is situated at the free space present between the pairs of support members (12, 13) and positioned below the abutting means of the device for applying the labels, the second conveyor means comprising pairs of idle rollers (22, 23) and being activatable in such a way that the pairs of idle rollers (22, 23) are movable along the upper branch according to a movement direction in the advancement direction of the pairs of support members (12, 13) and with the relative axis arranged transversally to the movement direction and so that each pair of idle rollers (22, 23) is interposed with each pair of the support members (12, 13) and advances in synchrony therewith, the upper branch of the second conveyor means having an ascending portion that is conformed with respect to the conveyor portion of the first conveyor means in such a way that the rollers (22, 23) of the pairs of rollers moving along the ascending portion abut the products transported by the pairs of the support members (12, 13), on which the label has been applied, and raise the products from the housings (120, 130) of the support members (12, 13) so that the products are supported only by the rollers (22, 23) when they transit at the abutting means of the device for applying the labels so that the products, when abutting the abutting means, rotate about the relative axes and the label is folded and adhered to the cylindrical lateral surface, or portion of cylindrical lateral surface, of the products.
